Q: Unable to boot - please help

Hello,
I am having trouble getting into Windows XP. Every time I boot I get this message:

STOP: c0000218 {registry file failure}
The registry cannot load the hive (file):
\systemroot\system32\Config\SOFTWARE
or its log or alternate.
It is corrupt, absent or not writable.

Beginning dump of physical memory
Physical memory dump complete.
Contact your system administrator or technical support group for further
assistance.

The system then restarts and repeats itself.
Does anyone know how I can fix this? I don't want to lose my files.

Any help would be greatly appreciated.

EDIT: I have also tried getting into safe mode and that will not work either.

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.)

Win 7x64
Acer-5251
Everything seems to be working fine, but as the title suggests, when i tap F8 the Advanced boot options DO appear, but when i engage "Repair Windows" it just goes into a normal boot. Ive tried booting from my installation CD that i've purchased from Acer, but does nothing. And Yes My CD Drive is working, as well having this set as top priority in BIOS and CD is in good condition.

In addition to this, ive tried using the "Advanced Recovery options" from within Windows itself but when i go to click restart computer, i get an error message, with red-x, stating windows is unable to restart.

Additional info that may be relevant, is that a few months ago, i had a friend work on my computer, because windows wouldnt boot at all. When My laptop was returned to me, everything was fresh, but there was missing programs etc...He said, he had to format the hard drive to get it up and running again.

Anyway i appreciate any help as to what i should i do next, or answer any questions you may have-Thank-you!

When I try to start my laptop the 'Acer' logo flashes with 'press f2 to enter setup, f12 to change boot device, then to a black screen with a flashing cursor but unable to type, then screen turns off and it just repeats over and over. I'm unable to start in safe mode. I don't have the original Windows disc and no access to another computer, at this stage. I have a wireless keyboard and when I plug in the dongle am able to use it. 
 
If I press f2 then I'm able to access 'Phoenix Securecore Tiano Setup' with tabs for Information, Main, Security, Boot and Exit.
 
Before the laptop refused to start it was having an error about not being able to write to drive. I ran two programs, one anti malware and the other I think was Glary. I was able to start both in normal and safe mode at this stage.
 
Anyone have any ideas how to fix this? Dumbed down advice would be great!

Hi,
This morning I went to use my laptop and it is no longer booting.  The power will come on and the power button lights up, the keyboard lights up.  If I let it sit it will stop running after around 30 seconds to 1 minute.
If I click the power button after it started, I can hear the fans spin up then the system shut down.  I have ran the LCD test and it works.  Their is no boot screen at all or dell screen.
I updated the bios last week and I had run it since.  I also took the whole thing apart today to remove the bios battery for 1 minute and put it back together but it still does not run.
Is their a way to diagnose motherboard issues?  why would it not boot or is their more steps to look at?Thank you

Welcome,
I'm assuming that you are currently communicating from another computer.
Do you have the installation disk? If not, then the trip to the PC wizard sounds like a wise choice.
The data loss will depend on what is wrong and when you made your last backup. It could be very little to total.

Hello there,

I have a problem. I have a dual boot computer with Xp on C: and Win2k3 on D:

As my XP is behaving very weird lately, I intend to reinstall my C: again with XP again. But if I do so, my Win2K3 on D: will fail to start. I have done this experiment on a spare machine.

Does anyone know how I can reinstall XP on my C: and yet make sure that my Win2K3 still works well on my D: ?

Any help is greatly appreciated.
 

A:Win2K3 unable to boot after installing WinXP as a dual boot

Yes. You need to restore the boot environment that was installed with Windows 2003 server. Its more up to date than the one that was installed with XP, and is capable of booting both, whereas the older XP one you now have can only boot XP and not 2003.

I believe you will be able to get round this:

Install XP.

Backup your boot.ini file.

Boot from your Windows 2003 CD and begin an installation.

After the text based stage, where the files are copied to the hard drive, STOP THE INSTALLATION BEFORE THE GRAPHICAL STAGE, AND DON'T FORMAT!!!! You can do this by booting from the Windows 2003 CD instead of the HDD.

Then, boot from the Windows 2003 CD into recovery console, and rename your old boot.ini file as the new one.

Basically, you are wanting the Windows 2003 installation program to write its boot environment to the HDD again, but not to reinstall the OS.

You get around this in future by installing OSes in the order they were released, from the oldest to the newest, so that the following would be installed in this order:

Windows 95
Windiws 98
Windows NT 4
Windows 2000
Windows XP
Windows 2003


I hope this helps. Sorry if this is a little vague but its early in the morning. Post back if you still have questions, but I've encountered this problem many times and that was how I fixed it. I don't recall fixboot or fixmbr from the recovery console helping.

Hello,

I own a HP Pavilion Tablet with Vista Business. I haven't noticed it until just recently that the CD-ROM drive disappeared off device manager. In an attempt to remedy the problem (hoping it was a software problem), I do what I usually do: rstrui. When recent restore dates didn't work, I turned the clock back the oldest state I had, which was back in late September. Next thing I knew, it wouldn't boot properly. It would pass the initial stage but would eventually end up on a blank screen. However, the cursor is visible (and movable). I can't progress through this point. BIOs is unreachable and it cannot boot from CD. I am unsure as to how to proceed from here. Any help would be appreciated, thank you.
 

A:Unable to Boot; Unable to detect CD

First and foremost, read your manual as to how to do a system recovery. There will be a key or key combo to hit when powering up like F11 or whatever. This starts the system recovery.

Note many of these will overwrite ALL data on the drive. If there is info you need ie work files, data files, etc; I would pull the drive and slave it to a working system. Copy whatever data you need. Reinstall the drive and do the recovery.

So I recently got some laptop parts to upgrade my laptop with from my friend who had the same model. Everything was working until I switched the harddrive (Big mistake). I thought since the model of laptops was the same, it could just be swapped in, but I was wrong and now I can't completely bootup my laptop with either drives. (I'm currently trying my fixes on my original drive)

On a restart after it downloaded some drivers, the device scanned the harddrive for consistency which deleted a few things. Since then it is mostly unable to boot (there have been a few times that it booted up but they are few and eventually they shut itself back down) and throws me in a bootloop even after I switched the original harddrive back in. I can boot it up successfully into safemode and use my windows recovery disc to boot up my laptop but neither of those are permanent fixes.

I've tried using the built in startup repair multiple times but it says it is unable to fix the problem. Looking at the logs of the scan, it says the root of the problem is a corrupt system volume disk.

I've also tried using system restore to earlier time but no luck. I've tried last known good configuration but didn't work.

Dear All,

My computer has been infected with a Boot.TidServ.B virus.

Norton Recovery Tool has detected it, but can't fix it. Is Norton Power Eraser likely to be able to kill this kind of virus? What other options are available? NB the computer can't boot up, including in Safe Mode, so any solution would have to be run from CD/DVD ROM.

I've done a bit of research and come across an application called "TDSSkiller" from Kaspersky - is this likely to work? Note that, again, it would have to be run-able from CDROM.

Thanks in advance for your help.

Hey all.
This is probably the biggest problem i've encountered with windows ever and i actually suspect its my hardware but not sure how to prove it and what step to take next if it is.

I have w7 installed on a SSD 64gig (C ) and most of my apps/games etc on a standard 1tb HDD (E )

The problem:
-as of yesterday, on starting the computer, windows 7 fails to boot, it goes to the w7 splash screen for about 15secs and then the monitor flickers off and the system restarts. W7 then gives the option to start normally or in repair mode.
-I've gone through repair mode now and tried both the startup repair (9 times, it finds no specific problem),
-the system restore, which lists 3 possible restore points (each one says success but then the same loop as above occurrs anyway)
-Ive also tried the bootrec commands via the command prompt available in system recovery.
-When i try to boot in with safe mode it goes black with a cursor and stops there
-when i try to boot via the dvd, it loads the windows background and cursor and stops there.
-In safe mode via the dvd it loads black screen and the 'safe mode' text in each corner and white cursor and stops there.

so at the moment i can't actually even do a repair or even clean reinstall via the disc which is pretty disturbing.

Problem
My hard drive will not boot without using a bootable CD to reference the Windows partition.

Symptom
When I power on my computer, the BIOS POST displays, then a black screen with a blinking cursor (_) in the top left appears. Nothing happens after this, no error messages or anything.

Current Workaround
I can place Hiren's BootCD (Hiren's BootCD 15.1 - All in one Bootable CD ? www.hiren.info) into the drive, and allow the computer to boot to this CD. Once it is booted, I can scroll down to the menu option "Boot from Disc 0, Partition 2", and the Windows 7 install on my C:\ drive will boot like it should.

BackgroundThe drive originally shipped with Partition 1 as a 10gb recovery/restore partition, and Partition 2 is where Windows 7 was installed.
At some point, the recovery partition had data on it accidently deleted, rendering it useless.
Ubuntu was installed as dual-boot with Windows 7. This shrunk partition 2 (Windows 7), and added partition 3 (200gb) and partition 4 (50gb) for Ubuntu. It then booted to a GRUB bootloader which had Windows 7 as the last option on the list.
Uninstallation of Ubuntu. I used the methods shown at this link: The Non-Geek?s Guide To Safely Uninstall Ubuntu From A Dual-Booting MachinePartitions 1, 3, and 4 were deleted using EASUS Partition Manager in Windows.

Rather than using the Linux boot menu because it showed me Windows 7 twice rather than Windows 7 and XP So I used EasyBCD in Windows XP and added XP to find the drive its self and linux as well. Linux and windows 7 I can boot ok but when I choose the option for XP it just goes to a black screen no windows loading screen or anyhing just a black screen.

Does any have ides with this for me?

My first view of this is that you failed to check the box in EasyBCD
Run EasyBCD.

I have to unplug and plug the power back in again for this to happen once more. I've tried taking out the power button connector and bridging the gap with a paper clip and I get the same effect as pushing the power button, so I can assume it's not the switch. I've also had a good luck around the case and I can't see anything that could be causing a short. Has anyone else got any ideas or could it just be that I need a new power supply?

'Houston we have a problem.'

I think I have a problem for which there is no easy solution but I thought I'd post in case any of you guys can help.

Came to switch on my desktop PC yesterday which runs XP Home and has been happily running OK for many years but after the initial boot up the message "Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM. You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair."

I tried the above but it then appeared that the CD drive wasn't being recognised, despite its LED flashing, since the CD was ignored on the re-boot and the same message then appeared. I trawled the web looking for solutions, tried a few things but have got nowhere. I managed to download an XP recovery .ICO file and burn it onto a CD but again that seemed to be ignored on a re-boot.

I seem to have big problems but can anyone suggest how I can fix this in the easiest way, if at all, and at least get to a point where I can copy in the missing file(s), as explained on the Microsoft website, or at least get to where I can reload Windows XP again from the CD. Otherwise it looks like I'll need a new hard drive at least or another PC.
 

A:Unable to boot up

Hi,

You can try booting with a Win98 floppy disk (google for how to make the disk and where to get the source), copy there the missing file and move it to your HD.

Another thing is to ensure that the computer can boot from CD, check on this within your pc bios settings.

Ask the owner if it has happened before. Don't worry about being blamed. It's probably related to their CMOS settup.

I'm in need of some hardware tech support... My desktop is a Dell Inspiron 580. It's about 5 years old and running Windows 10.
Last night I was updating iTunes and iCloud Windows and when it wanted to reboot to finish the install it never recovered.
When I boot up, I get the Dell progress bar and the options to select F2 Setup or F12 Boot Operations, then a black screen with a blinking cursor in the upper left corner.
All the diagnostics run fine. All the keyboard lights work appropriately.
I've created a Windows 10 recovery USB but it won't let me use any of the recovery took with the message "This option is not supported on the operating system you've selected"
If you've got any helpful suggestions on restoring this computer (first choice) or recovering my data (second choice) PLEASE chime in.

Long story short my computer cant boot from a bootable usb.

Long story long, Yesterday i tried to format my computer with my windows 7 original disk, my computer does not have a slot for a cd player so i plugged one in and it was just laying there on the ground, i put my windows disk in and it was vibrating like crazy so i wanted to move it on a pillow, while doing so i tilted it a bit at it and it completely ruined the cd, i cant boot from it anymore so i lend a bootable usb with windows 7 on it, and put my bios priorites to boot from the usb and it gives me a screen with lines going down in different colors ( Blue, green, light blue, red) With Weird compination of letters ( C ? L O( @ C, ) and so on. Like the same effect of a blue screen, i cant press anything and only thing i can do is turn it off and on. What causes this? Its not just this usb its also if my computer boots from my extern harddisk ( Without windows7 files on it just picutres) So im guessing the usb isnt bootable? Or is there a setting im missing in the bios.

Thx for reading my rambeling

Setup:

intel i7 3930k
gigabyte x79 ud3

I made a mistake of re-partioning the 2nd HD ( 1 of 2 40Gb drives) this somehow corrupted the boot sector of the other drive with XP installed, I cannot boot the XP from the CD-rom drive the disk is not recognised as a system disk.

So I installed a new WD 160GB drive but still the same problem the message says non system disk and I have also tried soem diagnostic disks like the the one from WD.

The bios is correctly identifying both the new 160Gb HD and also the CD-ROm which is an Imation, which is now about 4-5 years old.

Everything was working before I screwed up, except I cannot be certain about the CD-rom, could it be this is not working properly.

I have a floppy drive but no boot disk and no way of making one.

Please anyone can you advise what to do.

I am trying to format my computer to install Windows 7 as support for my current system XP Pro. runs out in 2014. My problem is the computer refuses to boot to the Win 7 installation disc I might add this is a legally bought retail disc of Win 7 Home premium with valid key. I go into the BIOS set the boot sequence to CD first HDD second when the splash screen comes to press any key to boot from CD it just continues a normal boot into Win XP.

I have checked the installation disc in my spare computer and it starts to load the Win 7 OS with no problem so that confirms the disc is OK. I have re-set the CMOS, disconnected the onboard optical drive and tried an external optical drive went back into the BIOS and set it to boot from the USB CD Drive but all to no avail. I have run scans with AVG, Malawarebytes, Super Anti Spyware, and the E set online scanner all have come up clean. Also I have tried booting with other bootable disc i,e, Killdisc and so forth, none of them will boot after I hit any key to boot when the splash screen appears. I have also tried to set the boot menu in F12 to CD first but when I enter it the up and down keys on the screen to change the boot sequence are not active.

I disconnected everything from the computer except my keyboard and tried to boot to the disc, but that did not work. I would have tried a non USB keyboard but my MOBO only supports USB. My computer specs are as follows.

Hi all,

So I am trying to do a PXE boot for an HP 450 G4.
I tried to change some settings in the BIOS like enabling legacy support and disabling secure boot.
When I tried to do that, and then re-enter the BIOS to see if those settings were applied.
It went back to square one as if I did not request that change in the BIOS.
The settings will not stay as enabled, it goes right back to being disabled.
So I tried to disable every boot option to get the UEFI option unchecked and I have not been able to.
I even created a BIOS password but nothing.
When I changed the settings and rebooted the laptop, I got a code to enter and tried the network boot but every thing I tried carried me back to the setup screen.
Other laptops work with the network boot so its not an issue with the network boot (i think?).

I need this laptop to do the PXE boot, I do not know what else to do to get this thing to work.
Thanks for any assistance that can be provided.
 

A:Unable to do a PXE boot for HP 450 G4

PXE boot has nothing to do with UEFI. First your network adapter has to support PXE boot. Second, you need to change the boot order of the laptop to have the network adapter in question at the top of the list.

I recently had some issues and I reinstalled xp professional. I started the upgrade installation and I turned off the machine. I should have just let it continue with the installation, but I was concerned it would overwrite data.

After some research, I learnt that the "upgrade" installation doesn't overwrite data. It's similar to a repair installation. I have restarted and completed the installation. I sat here and watched it copy all the files to the drive.

When I boot into windows, it takes me to a black screen with my mouse curser right in the middle. Nothing else... Did it get confused or something? What is causing it to not take me to the desktop?

How can I fix this?

Hi, scking!

"When I boot into windows, it takes me to a black screen with my mouse curser right in the middle. Nothing else..."

Please, answer the following questions:
* When you first turn on your PC, do you see your HDD light flickering/turning on/being on?

* Can you boot into safe mode?

* Can you get into your BIOS at all?

Your HDD could be dead, which is a very bad thing, meaning you'll have to replace it - but lets not jump to conclusions yet.

How to create a Windows XP boot floppy disk

Is it possible to use another installation CD or perhaps, try installing again? You could always boot into Safe Mode with CMD and type "FORMAT C:" to erase all your data and your OS (I think it gets rid of your OS), so you could get a fresh start.

I could be mistaken but it sounds more like a hard disk error.
At the post screen can you see the hard drive initialize.
Can you here the hard drive spin up
Do you know how to enter bios and check on the hard drive settings. If so make sure the primary ide master is set to auto detect or manually detect it, make sure it states the correct size for your hard drive.

I was trying to fix a friends computer because it wouldn't connect to the internet...when my tech son came in and checked it all out and told us she would do well to do a restore or repair. So he started the restore and I am not sure what he did, but it really made it lots worse! LOL Now this is all I can get the computer to do:

Hi, I'd like to ask you for your help. This morning I turned my PC on and immediately after that there was a crazy fan loud noise, nothing on the screen at all, all mobo lights were on and there was one beep, bit louder and longer (about 1 sec long) than the usual POST beep. And of course it didnt boot.

I need the computer for work real bad so I cant afford to leave it somewhere for a week for repairs.

I didnt see or smell anything burned.

The configuration is:
Gigabyte GA-P55-UD3 (rev.1.0)
Intel Core i5-750 BOX
Kingston HyperX XMP Genesis 4GB (kit 2x 2GB) 1600MHz
Sapphire ATI Radeon HD 5850 1GB DDR5 21162-00-50R
Enermax PRO82+ II 525W Bronze
Intel X25-M (34nm) 80GB
Seagate Barracuda LP 3.5" 1.5TB ST31500541AS
OS: W7 Home 64bit

After googling up the problem and reading several similar threads (interestingly though all of them had no beep so I dont know how much relevant they were to my problem) I tried:
- reseting mobo battery
- vacuing the dust in fans
- reseating videocard
- booting up with just one of the two RAMs (both of them of course)

None of that helped.

What I do for about two years and might be relevant to this problem because I don't think it's standard on desktop PCs is that I don't turn the PC off, just hibernate it.

What would you guys please suggest?

Sorry for missing aposthropes etc., im posting from a tablet.
