Preferred Solution: windows 7 booting stopped booting

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I have two HDs on my desktop PC and Win 7 installed on both of them. Recently there have been issues when trying to load either copy of windows.

One tells me there is disk inconsistencies and the disk needs to be checked. The other loads up the startup repair and tells me it's been repaired and to reboot my PC. When I reboot my PC the same process repeats.

I tired reinstalling a fresh copy of Windows but all that did is give me three Windows 7 OS to choose from when it asks me which one to load.

At this point I don't care if I have to format both of my HDs, I'd just like to get a copy of Windows working. It's weird that both copies on separates HDs stopped booting, could it be a virus? Anyways, please advise.

A:Windows Stopped Booting

Try booting with only one HDD connected. If that one doesn't work, try the other one alone. Post back what you find.

An image of your Disk Management screen would help too.

But here's my question: What reason do you have to load W7 twice on the same machine?

The system has worked in the past, and now after entering the user password the computer crashes and starts.
This may have been caused because the drive was run on the command "attrib -R -A -S -H *.* /S /D /L".
I do not remember if the system worked properly since then.

Two weeks ago I purchased an ASUS M32CD PC Desktop with Windows 10 Home 64bit pre-installed, and now all of a sudden it's not booting.

When I set up my pc for the first time after I bought it, I mistakenly agreed to participate in Windows Insider Program, and shortly after setting my pc up, Windows Update automatically downloaded and installed a newer Windows 10 build which took about 4 hours to complete.

Since everything was still working great after the new build, and I had the option of going back to my previous build through recovery settings within 30 days, I decided to test it for a bit. Last night I decided I wanted to go back to the build which came pre-installed on my pc, and when I clicked on it via the recovery section, it said the files needed to revert back had been deleted and that I could not go back to previous build. So I decided to just Reset my PC instead. It gave me the option of keeping my files and settings or deleting all files and settings and reinstalling Windows. I chose the latter. It went to a blue screen that said Resetting your PC, and once it got to 2% complete, it abruptly ended and said there was a problem resetting my PC. I tried it one more time, and at 2% it again ended and said there was a problem resetting my pc, and I was given the option of going into advanced recovery.
From there I chose to continue to Windows 10, but it would not load anything. Since then I have tried to use the Windows Repair function, but it doesn't re... Read more

In this form I hope to solve PC errors, thanks for the help everyone!

I've a lot of PCs, all of whom have Windows 7 Enterprise and XP dual boot.

Nowadays, suddenly in many PCs both the OSs stopped booting, but I'll query about Windows 7 in this forum.

When Windows 7 starts to boot, as soon as the 'glasses' of the Windows logo appears, Windows 7 reboots.

On booting from safe mode, the restart happens after classpnp.sys is loading/loaded. I tried renaming that file, but then the restart happens on disk.sys, on moving that file too, it happens with fvevol.sys.

I tried to enabling boot logging (from F8), but there's no ntbtlog file in the Windows installation directory.

Please help me solve this PC problem!

A:Windows 7 suddenly stopped booting.

Welcome to SevenForums!

You mentioned you have many PC's with the same problem. The first thing I would look for is any updates that were installed on the machines shortly before the problems started.

If the PC's have System Restore active you might want to boot using a Install or Repair disc and restore to an earlier date.

Also try running Startup Repair, Startup Repair You may have to run it three times, booting between each run.

I try to never touch any machines that are dual boot, sorry I don't really have a lot of suggestions.

I have a Dell Inspiron n5110 and, like the subject states, the fan stops working after booting up Windows 10.
I just noticed this lately, so I can't really pin point the cause, but, I believe that it's only recent since my laptop ran smoothly in the past (I was playing the Witcher with medium settings, I was rendering 3d models/scenes with thousands of polygons, etc.), but now, it overheats every time I play and then shuts down.
I already tried cleaning the fan, replacing the thermal paste on the CPU and the GPU.
The fan works when I ran Dell Diagnostics and when the system is POST-ing (upon start up), then when the Windows 10 logo appears, the fan stops. I already tried looking for a driver, but I think fans don't require drivers...?

Any help/suggestion is appreciated. Thank you! :)

Had to to a format :drive /p:2, that is format with zeroing out the secondary flash drive which still had some boot loader, that activated randomly screwing up the system boot. Turns out the Asus Flash Erase is worth sh*t.

I've got Windows 8.1 Pro x64 installed for a month now and up until today everything was running smoothly.
Today the Os will not boot though, the boot process hangs during the loading animation, similar thing happens, when I try make a new install or repair the system using the repair tools from the dvd - when I click "Repair Tools" or "Install" nothing shows except for the blue background.
The problem goes away, when all other drives, except for the one with the OS, are disconnected.
I use a following build:
MB: Asus Maximus VII Gene
- Plextor m6e m.2 pci-e ssd<- Windows 8.1 installed
- 4 x WD Green as archive
- Crucial m4 SSD for vm's
Removing all drives except for the helps, however that is not really a solution. Disabling the SATA Ports does not help either, they have to be physically unplugged.
Also! - after disabling the Plextor drive an keeping the other drives connected, right after POST there is a message about a missing windows bootmgr. It's in my native language (now I have 8.1 en_us, a month back I had another installation on the Crucial ssd), so it seems the second bootloader is somehow interfering (?) although like I said, everything was running with no problems for a month.

I searched the threads for an existing post and I couldn't find one that matched my problem. Sorry if a solution has already been posted somewhere.

I have a new Acer 1410 w/ 4GB of DDR2 memory and a 1.6 CULV processor. It came with Vista Home Premium installed, but I downloaded Windows 7 Ultimate from my technet subscription. Because I don't have an optical drive I had to install from a USB stick. I did this without any problems at all.

Windows 7 has been booting fine and running great for about a week now. I haven't recenly loaded any new software or drivers. Yesterday I shut down my laptop normally; when I tried to reboot an hour later I was shown the "loading files" screen and was then taken to the Windows Startup Repair option. Windows spent an hour trying to repair whatever was wrong with my startup and I was finally given an error message that it couldn't make any repairs.

I tried going to the DOS prompt and fixing the boot manager and boot file; interestingly all this did was suddenly give me the option to boot Windows 7 or Windows Vista (!!!). I still get the Windows Startup Repair when I try booting Windows 7. If I try to boot Vista (I was curious) it takes me all the way to the login screen but then tells me I have files missing if I try to login, which is fine - I wasn't trying to set up a dual boot anyways.

I partitioned hard drive and everything. Then I installed XP Pro and Vista. Then I updated both and whatnot. I was on Vista then I restarted and booted into XP. Now when I try to boot into Vista it gets to the loading screen then it just restarts. I can still boot into XP fine.

Also I have lost all access to my BIOS. Does anybody know how to get that back?

My PC has two SATA drives, for storage, and two 128GB SSDs. One of the SSDs has Microsoft Flight Simulator (FS9) installed on it. The second is divided into two partitions: the first has the O/S, the second Microsoft Flight Simulator X (FSX).

The first sign of trouble was when aircraft fuselage textures stopped loading in FS9. Eventually, when this didn't clear, I decided to reboot. After I did so, the FS9 SSD was completely missing from My Computer. Tried rebooting a couple more times. No joy, and the Asus BIOS splash screen was taking ages to move onto the Windows is starting up phase, so I assumed that the drive had failed. I unplugged the faulty SSD, and all was OK. For two or three reboots...

Then, rebooting once again a little later, all I got was, after the BIOS splash screen, a black screen with one line of strange characters. A few letters and numbers there, but mostly stuff like you might find in Wingdings font, musical notes, patterns and shapes. I took a photo of this. I can post it if really needed, but don't expect the exact string will help much. It's the same string of characters every time..

I booted using a BartPE DVD and went into the explorer utility. The O/S drive itself is clearly OK (it would be a bit much for both to fail in 30 minutes!) as both partitions on it, the one with the O/S and the one with FSX, are accessible in BartPE and I can browse through the various folders.

Also, the small System Reserved partition with a folder called 'Boot' an... Read more

I got a new disk drive for my pc and as soon as I got it installed Windows 7 would no longer boot after the start up screen. The error I get says "Windows has failed to start. A new hardware or software change may be the cause."

I've looked up the error and I've tried starting it in safe mode which won't work, I don't have a backup to reset my computer to and the option it gives me to repair the computer works but it sits on the repair screen infinitely. The only option I have found left is to reinstall windows or use the repair disk, but the computer was unfortunately gifted to me and was gifted to someone else before me so there is no disk. I just wanted to know of any more options before I got but a new OS to save my baby.

Hey there,

I have a Dimension C521 Dell desktop PC. It is a glorious computer; have had it for 5+ years now, and have had very few problems with it, and when, nothing a virus scan or system reformat wont fix. Its all been great, until we got this. My sister went on a website (Roblox, I think), and my brother occasionally plays Runescape on it. The anti-virus software has always been iffy with Runescape, showing multiple viruses, but we could always fix it. Not until Roblox went up. Shortly after, the PC froze, so I had to do a hard reset. While rebooting, we got an annoying ticking noise from the computer, down where I think the HDD is. I'm unsure if this is the "click of death", but comparing to Wikipedia's media of it, it sounds different. The noise is somewhat a click, sometimes going 2-6 times in a row, stopping, then repeating. Father (who has been helped before on this site; thank you!) thinks its the PC trying to boot from the CD drive yet failing. Well, being the ignorant person I am, I ignore it and continue...

Everything is similar, except...

Boot from CD:

What we think is that something deleted our boot drive.

So we find the system disk, and insert it. It downloads the files, and then goes to:

A:Windows XP PC stopped booting, lost boot drive?

Try pressing F2 and entering the setup menu. Once there, find the boot disk priority (usually in the boot tab) and make sure the hard disk is at the top of the boot list. If the hard drive is not on the top of the list the computer will try to boot from other devices and could cause the error you're seeing.

Ok computer has been doing scandsks for the last week all of a sudden when starting up and now it splashes the boot screen and hangs on the black screen with a blinking cursor at the top left.
I have been researching this for the past couple of days in the net and unfortunately have been unsuccessful at finding ananswer.

heres what i have done so far:
1-booted from windows cd and did STARTUP REPAIR, it found my windows installation and finished without no problems - PROBLEM STILL EXISTS
2-command propmpt and fixboot command unsuccessful since it stays on x: dir and i cant find the c: dir for the right commands
3-SYSTEM RESTORE found no earlier restore points which i found odd but it is what it is.. lol..
4- went ahead and tried installation of windows to see if it recognized my drive on array and it did with the correct size and data.

I tried installing the regrun reanimator to see if it maybe was a root kit problem but the boot up disk didnt recognize my c drive either.

so here i am stuck on stupid!!..

I was trying to install a ubuntu distribution to my primary hard drive (along side Windows 7) and at 99% of copying files the setup reported there was not sufficient memory to install backtrack. I cannot boot back into windows 7 as the computer resets before getting past the boot screen (shows 'starting windows' as normal then the screen blacks and takes me back to BIOS).
this process loops unless I select windows repair option, which does not fix the problem.
The Backtrack live CD won't let me delete the new, half-installed partition, so therefore I cannot change the windows partition back to it's usual (small) size of 55GB.

All help would be appreciated as I need windows on my PC for work

Just tried to add Crucial ram to a used Precision M6500 Win7 Laptop - 2.8GHz core i7 *GB SP1 on EBay last week. After taking advice from Crucial tech this laptop will no longer boot.
Apologies for the long explanation: 
Working machine came with 8GB (2x4) of Hylinks Ram. I added 8GB (2X4) of Crucial memory under the keyboard of the machine. The machine would not boot. Pulled memory from all four slots. Put one stick of Hylink and one stick of Crucial in battery side slots to see if they work together there. The machine booted windows. So I put the other Hylink and Crucial sticks under the keyboard. The machine did not boot.
I called Crucial. Tech told me to pull the cmos battery. Wait 15 minutes and plug it back in. This is were the real fun begins!
Now the machine won't boot windows under any condition. 
I pulled the the additional memory out from under the keyboard. The machine runs the memory test and blue screen flashes on and off in a split second. It goes into startup repair mode. And ends with the following report every top I push the start button:

"Windows failed to start. A recent hardware or software change might be the cause.... 
Launch startup repair (Recommended)"
Start up repair does not work. The machine will not boot Win7 with either 8 or 16GB in place.
So it seems pulling the cmos battery is at the bottom of this. But for the life of me I can't figure out why?

Recently I purchased a laptop with windows 8 64 bit pre-installed in it. For my job purpose, I needed windows 7 32 bit. After searching the web and also using the information I got from this site, I disabled secure boot, deleted the recovery partition and converted GPT partitions to MBR. Then I shrink the Big partition in which windows 8 was installed to make room for the windows 7 partition. Then I created a new partition and installed windows 7 on it. After this whenever I switch on the computer, a message come up, saying that a required device cannot be found and windows is to be repaired. The only way in which I can start windows is to go to bios, select the boot options and then select boot from notebook hard drive.

Can anybody please tell me how this problem can be solved

A:Booting problem with dual booting with windows 8 and 7

when you created the new partition did you make itin front or behind the existing partition?

If your boot manager is looking to boot Win 8 on Disk 0 Part 1, and you created the new partition in front of Win 8, your Win 7 will now be located on Disk 0 Part 1 which is where the boot manager is expecting Win 8

can you send us a screen cap of your disk management?

Hello All,

I have a HP Pavilion zv5000 running XP and i can't get it to boot anymore.

It did boot and work for a few times after i got it but now it doesn't. It would do the initial surge where the fans come on but then it would silence and turn off after a few seconds and the screen stayed black.

I removed one of the memory sticks and booted, after the initial surge it stayed on unlike before, but it didn't kick on further and still nothing came on screen.

I did try a different screen from one of my other pavilions as i know they are prone to inverter problems but still it just stayed black.

Does anyone have ideas please, i really don't want to have to take it to a shop.

A:Laptop has stopped booting up.

If it was a faulty hard drive you would still get something up on the screen, with an error message relating to the hard drive, so that's not the problem.

Similarly, with faulty RAM. you would get a series of fault beeps from the BIOS which I assume you are not getting?

I assume you've tried turning it on while it's connected to the A/C adapter (in case the battery is flat)?
If yes, then it's my guess the motherboard is faulty. Only an inspection by someone who knows about the insides of a laptop can confirm that I'm afraid.

I've had this computer for several years and just recently it's been having various problems and now it's not even booting up anymore.

Some previous problems that led up to the boot up problem.

Most recently when using the computer, suddenly it seems to freeze up and after several minutes the display/resolution goes from my regular setting (I believe it was set at 1024x768 32 bit, to 256 color 640x480.

It was happening almost on a daily basis. It got so bad that instead of using the computer locally, I would log in from my laptop using Remote Desktop and using the computer this way instead. I was not sure if this was caused by a faulty video card or maybe the motherboard was having a problem.

I have an ATI All In Wonder 9800 AGP video card. It's been working fine for about 2 years but recently I was having problems using the TV tuner. When trying to use the TV Tuner I get driver errors. I've tried several different drivers from ATI but to no avail.

I have an advent verona netbook which had win7 installed from new.

recently it was becoming very sluggish, this was followed by it not responding at all and all i could do was boot into safe mode.

Now it will only boot to the recovery options (startup repair) and regardless of what i click (attempt to fix error / reinstall windows / etc ) the computer just hangs, freezes or does not respond at all to key / mouse presses.

So what are my options ?

The computer has no disk drive and came with no install disks etc - so thats not an option.

I can enter command prompt from the start up repair so my inital thought was f disk and try to install my copy of vista on it which ive put on a memory stick - but even when i boot from the memory stick i get the options to install vista but then its just the same freezing / hanging and doing nothing .

Is there a way i can completely wipe the computer ?

Any help much appreciated as im at a complete loss now


A:win 7 has stopped booting .. what are my options ?

Burn a Win7 Repair CD to run Startup Repair which doesn't depend on OS files: System Repair Disc - Create. You can write ISO to flash stick using Win2Flash.

Make sure Win7's 100mb System Reserved is still marked Active so it will repair: Partition - Mark as Active.

If it won't start after running 3 separate Startup Repairs with reboots, mark Win7 partition itself Active to run Startup Repair x3 again to write the System Boot files directly to it as the 100mb boot partition may have become corrupt.

System Restore should be automated in Startup Repair, but run it next anyway.

You referred to a choice on your System Recovery Options list to Reinstall Win7, which means you have a Recovery Partition from which you should have made Recovery Disks. You can order these disks from manufacturer's Tech Support for a nominal fee if you didn't make them earlier.

You can also clean reinstall with the Product Key on your COA sticker following these steps: Reinstalling Windows 7

Copy out your files with Repair CD or DVD using this method: Copy & Paste - in Windows Recovery Console. If you can find the install.wim file in the Recovery partition which won't run, you can also mount it to run Factory Recovery.

I have an HP 15-F233WM laptop that suddenly stopped booting.  After pressing the power button, all that would happen is the power light would come ON as well as the wireless button light (F12). I was able to determine the single 4GB memory stick has become defective.  I put a 2GB RAM chip into the laptop from my wife's working machine and it came back to life.  As a test I put the original stick of RAM back into my laptop and it wouldn't boot. My question is, the machine is still under warranty for 45 days.  Can HP send me a new stick of RAM for it instead of having to send the machine in?  The defective memory is made by Kingston, and has an HP replacment part number sticker on it 891740-001. I don't think I ever had Kingston memory fail before.... Thank you!

A couple weeks ago following a Windows update (may or may not be related), my Toshiba Satellite L675 failed to boot up. After trying a few dozen times to reboot (and a lot of simple/ineffective internet troubleshooting), I let it sit for a number of hours, after which it booted up and I could find nothing wrong. But after powering down, it failed to boot again until the next day, again after trying to boot it a few dozen times. Before powering down, I did a restore to before the Windows update initiated, so the update doesn't seem to have been the problem.
What happens: When I push power, the machine powers up, the disk drive powers up and the wi-fi light comes on, but it won't boot. Nothing else happens. I have to hold down the power button to power down again.
The next time it finally booted up, following the advice of a Bleeping Computer mod, I moved a lot of my files to an external storage drive to increase the free space to over 25% (currently its over 50%). This got it to start booting again. He also checked out my system and said there are reasons to believe I may have an infected machine, and to bring my problem here.
After about a week of booting up properly, my computer has gone back to not booting up again. It takes so many tries and only boots up about once a day.
Thanks in advance for any help you can offer!

Got a feeling this is a hardware issue...

My Dad returned to his summer cottage after being away for the winter, had his cable turned and went to power up the pc and got nothing... the hard drive light comes on and it spins and sounds good but nothing on the monitor...however if I open the cd drive and put his 98 cd in... turn the power off by holding button...wait a few minutes...sometimes but not every time it will boot to a Gateway screen and stick there...at the left side of that screen are a column of numbers like this...



I have tried taping various keys as soon as I power up
pulled the battery from the mobo

I'm thinking I'm going to pull the hard drive out and try it in another machine

Any thoughts before I do that

I built my PC about a year ago and it had been working well until recently when it just stopped booting up. I asked my friend (who is IT savvy) and he suggested that I test/ replace my PSU. I was able to get a free replacement PSU from Amazon but even after connecting that (the one outside the tower in the photo), the PC doesn't seem to boot up. No lights, no sound .. nothing. The only thing that makes a little bit of noise is the new PSU. Is my motherboard gone? Or is it my power-switch that I need to fix? Or is it something else completely. Any help would be much appreciated.

Processor: Intel Core i5-6500 3.20GHz (Skylake) Socket LGA1151 Processor
PSU: Corsair CXM750 ATX/EPS Semi-Modular 80 PLUS Bronze Power Supply Unit, 750 W
Motherboard: GIGABYTE Z170-HD3
RAM: 2x4GB 2133MHz Kingston HyperX Fury DDR4 Memory
Storage: 250GB Samsung EVO 850 SSD and a 500GB HDD
OS: Windows 10 Pro

Some photos attached for reference.

I Installed Win7 ultimate yesterday on Fresh HDD .By default it took for System: 100 MB space, C:\123.22 GB (Boot drive) space and E:\174.77 GB .
Then I decided to resize C: drive partition to make more free space in order to create other partition.

I mean when I boot my PC it detect WD SATA HD but no go ahead from that status.Even I cannot change Bios nor change Boot option.

I am very worried. Please help me.

A:HD Stopped booting after resize C: drive

Are you able to enter BIOS?
Do you have a Laptop or a Desktop?

If you have a Desktop, try resetting your BIOS, by removing the battery.

Hi, I don't know if this is the righ forum, if not pls send me elsewhere...

Yesterday we did a disk defragment and today the hdd won't boot. It is accessible if I plug it into another computer as a secondary. So am backing up data now.

Can you recommend a utility that would allow me to sys the hdd?

It is running XP Pro and was installed as an upgrade from 98, so the XP CD I have does not boot.

I am going to try to sys it from 98 and was wondering if anyone has any other ideas.

Hey guys,
I own a Toshiba U500, bought it some months ago. Lately, it's been randomly crashing, and now, whenever I try to boot it up, Windows stops at the flag loading scene. Safe mode works perfectly, and I have tried startup repairing without success. I have also tried repeating the process from the installation DVD and it has failed as well. The last thing I tried was restoring the system to an earlier state (four days before), but it didn't work either. Any ideas?
Thank you all in advance.
These are the computer specs:
Windows 7 Home Premium 64bit
4GB RAM Memory
Intel HD Graphics (not useful here, but whatever)
I have NOD32 v4 installed, but I don't think it's a virus issue, since I haven't installed or downloaded anything new lately.
A quick answer would be appreciated.
It doesn't shut down properly either.

my specs are : intel c2d e4600 2.4ghz 2gb ram intel dg31pr mobo and nvidia 9500gt

wht should i do???? could it be a power supply issue?? and shud i try removing the small coin like battery and if i shud,then wht happens when i remove that battery and how long is it to be removed for?

A:PC stopped booting up, no display output

What power supply is it? (company, model, wattage,)

Most low quality power supplies will have little or no transient filter, which filter the incoming AC power and suppresses any voltage spikes. Most of the time when the power is cut the voltage spikes a bit.

Try removing your CMOS battery and you suggested and leave it out for about 10 minutes, and make sure you psu is unplugged and discharged.

You can discharge it by pushing the power button immediately after you unplug it, the lights and fans should flash for a second, then go off.

Hi there,

Recently, my computer has been very strange... I have been having unwitnessed BSODs (showing up in the reliability monitor), lots of hardware errors in the reliability monitor and multiple programs stopping working. The troubleshooting steps I took to try to solve these issues were: updating all drivers, testing ram with memtest86+ (8 passes OK), testing the hard drive with Sea Tools (all ok) and refreshing windows 10.

A couple of days ago, I experienced my start menu, Cortana all ?apps? etc. not working. So, I logged off, only to find a black screen with a curser! The only way to turn off was to do a hard shut down. After turning back on again, I got the usual windows start up screen and normal ?AVG watchdog starting up? text (see attachment). However, my computer freezes at this stage. AVG stops at ??finished? and the computer freezes!

After trying to boot into safe mode, I simply get the black screen and curser again.

Luckily, I have all files backed up and other computers to use, but I am really concerned about the root cause of my problems as I have had similar errors in previous installs of windows.

Would these problems be caused by hardware? I am happy to clean install if necessary? but I would like to find out the causes of my problems first.

Thank you very much for your help.

A:Laptop is not booting. It starts booting but restarts before it gets boot properly.

First thing to do is run an extended (NOT just 10 minute) diagnostic on the hard drive.  If you need further assistance, post the results of that (numeric error codes) along with the full model information - i.e., Inspiron N5110, XPS L501x, etc.).

Press F12 a few times immediately after powering on to get into the diagnostics.

So here's the deal, my GF's 3 year old HP laptop, a Pavilion dv6000 series, suddenly stopped booting correctly yesterday, every time it boots, a message appears saying:

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer".

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \windows\system32\config\system

Status: 0x000014c

Info: Windows failed to load because the system registry file is missing, or corrupt."

If I press enter, it then shows the OS I want to load, when I select Windows 7 Home Premium, the same message appears.

Any help would be greatly appreciated.

Have tried Repair your computer?

Boot up using the Startup disk CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, you will need a CD/DVD drive.
Make sure no USB drives are plugged in.

Do a Strartup Repair:

Note: You may need to do startup repair 3 to 4 times.

A:Vista stopped booting after update...or virus?

If you have Vista DVD, try to boot from DVD and performed system restore or if it fails you can do manual system restore by renaming the 5 files ( system, software, config, sam and security ) to e.g, sam.old in c:\windows\system32\config. Once you renamed those file try to copy those files from c:\windows\system32\config\regback to c:\windows\system32\config. You have to do a mual system restore by booting from Vista DVD -> Repair your computer -> Command prompt.

Good luck.

I have a dual boot w/XP and Win7

I've resized the two partitions to create a third data one.

Now XP hangs on this screen when booting. Same in Safe Mode

I can't enter recovery because it doesn't detect my installed WinXP.

Windows 7 works fine.

Thanks for any help.

PD: I've used MiniTool Partition Wizard.

A:[SOLVED] After partition resize XP stopped booting

Press F8 at the XP bootup in the Advanced Boot menu choose Safe Mode, does that work? If so, go to Start/Run and type chkdsk X: /F and press enter (X: being the drive letter that Windows XP is installed on). In the Command Prompt type a Y for Yes and reboot the computer. Check Disk will run at next bootup.
If this fails, boot off the XP CD and get to the Recovery Console and type the command.

I seem to always one into this problem every couple of months it seems.

I have a dual boot pc. One Partition has Windows 7 the Other XP. The XP boot looks like it got corrupted because when it boots it asks for I have to select "Last known good configuration".

I hit that it the xp boot screen comes up but it never gets past it. It looks like it searching for something that is missing.

I have EASYbcd but there help notes are not great.

Is there a simple way of fixing this with EASYbcd ? Or do I have to put off the Windows 7 DVD and fix it that way.

I just got a ASUS G75V series and updated it to windows 7 professional with Intel core i7.
I was able to work with it and everything was fine until I had to install XP because some softwares are not compatible with Win 7 x64.
I have Win 7 on drive C: and windows xp on drive E: which in windows XP environment it is shown as drive C: again(I have two HDDs, 500GB each).

So as you can predict I tried using the dual booting and followed the tutorial for that on the website, I wasn't able to get it to work exactly and each time I had to change the bios settings to boot either win 7 or win XP,

I downloaded easyBCD and was trying to get it to work but my silly mistake was I Reset BCD configuration under BCD backup/repair tab and ever since I haven't been able to load windows 7 and the laptop directly loads windows xp.

I ran easyBCD in windows xp and tried to fix the problem by adding the bootloader for windows 7 there but nothing seems to work.

I am really stuck and I can not reinstall windows 7 because it is set up with all the softwares for my work

A:Issue booting Win 7, booting directly into XP & no boot manager

It sounds like you have the OS's installed on two separate HD's, and were booting them correctly via the BIOS - setting preferred one first to boot in BIOS setup, then booting the other one using the one-time BIOS Boot menu key.

To restart Win7 unplug all other HD's, Mark the 100mb System Reserved (preferred) or Win7 Partition Active then run Startup Repair - Run 3 Separate Times.

Once Win7 starts, plug back in the XP HD and boot it using the Asus F8 one-time BIOS Boot Menu key, or install EasyBCD to Win7 to add XP on its Add OS entry tab.

I am trying to help a friend. Her computer would hardly boot yesterday, but after 10 minutes or longer, it would load. Programs hardly run and if they do are impossibly slow to run. Windows task manager keeps popping up. It won't close. We tried to set the registry back to an earlier date, but it won't take. My guess is that is a virus. She had AVG anti-virus running now it won't run either. Any thoughts? Any reliable online site which could scan the computer?
