MBR/BCD Missing/Invalid Unable to boot without Boot CD

Q: MBR/BCD Missing/Invalid Unable to boot without Boot CD

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

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.
Partition 2 (Windows 7) was moved to the beginning of the hard drive and enlarged to use the entire disc using Disk Management utility.
EasyBCD was started to revert GRUB so that Windows 7 could now load.
First problem After opening EasyBCD, but before messing with the settings, I closed my web browser, which automatically clears cookies, cache, and all temporary files. When I then pushed the button to 'Add New Entry' in EasyBCD, an error displayed saying it could not find C:\TEMP\somefile (which I believe was the working copy of the BCD store). No other operations worked in EasyBCD after that. Restarting the program resulted in an error message about it not being able to open the system's BCD store because it did not exist.

Rebooted, and current problem (blank screen with cursor) manifested.

Steps Taken So FarI rebooted with Hiren's BootCD, pointed it to Disc 0, Partition 2, and it booted to a Windows error message saying \Boot\BCD was missing. It stated I should boot with the Windows 7 recovery/repair CD and it would fix the problems. I rebooted with the disc, and after the progress bar "Windows is loading files...", a black and white Windows 7 background appeared with a mouse cursor, then the system rebooted before anything else happened. Thinking it might have made a change silently and rebooted, I left it alone. The same thing happened several times over again, and I decided it was stuck in a reboot loop, and it was not going to work.
I then rebooted with Hiren's BootCD again, and ran the Linux based partition manager live CD it contains. There were several utilities for fixing the MBR and the BCD, but none of them fixed the problem. The BCD program it contained would not work because it could not find the current BCD (which didn't exist).
I found the Microsoft article here: Error message when you start Windows 7: "The Windows Boot Configuration Data file is missing required information" which describes the problem, and proposes a fix. Rebooting to Hiren's BootCD again, I ran the Windows XP live CD it contains, and from there I was able to run some Windows commands such as bootsect.exe, mbrfix.exe, mbrutility.exe, mbrwizard.exe (I believe the versions on this CD are open source free versions, but I could be mistaken). With these utilities, I was able to do a few of the things on the list, but without bootrec.exe, bcdboot.exe, and bcdedit.exe, I was very limited.
I then found a Windows 7 rescue CD online which contained only the utilities (no operating system, just the repair utils), which was offered at a PC repair website. I burned this CD using Hiren's BootCD live Linux to a spare disk, and rebooted with it. This time it worked, and I was able to get to the repair menu.
I selected the option to fix the problems preventing Windows from starting, to which it said it could not find Windows 7 on my hard drive. I assumed this was due to the missing BCD, so using the methods here: Boot Manager gone :( [Archive] - My Digital Life Forums I was able to drop to a command prompt on the Windows 7 rescue disk and run them all. Everything worked perfect, no errors.
I rebooted with the rescue disk ran the fix boot problems option again, and it found my Windows 7 installation, and said there was an error with the partition table. I told it to fix it, and it rebooted and said there was no other problems.
When I boot, I still get a black screen with the blinking cursor, but now I can use Hiren's BootCD to select Disc 0, Partition 2 (Windows 7) and boot.
But I cannot figure out how to get the computer to boot to Disc 0, Partition 2 (or to make Partition 2 into Partition 1 if that is the problem?) on its own.

Preferred Solution: MBR/BCD Missing/Invalid Unable to boot without Boot CD

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.)

Any suggestions on how to recover my raid array or any of my files?

OS is windows Vista, the RAID is configured as a 10 (Mirrored/Striped) with 4 WD SATA 250GB hard drives,
mb is ASUS A8N SLI Deluxe, Silicon controller in use, NVidia controller not in use.

Rebooted machine, and received the following error:

No valide deivce!...press any key to continue

(yes the spelling is like that on screen...)


Tried rebooting a couple of times but no change. Ran the WD tools on the disks, "no problems".

If I do a Ctrl-S to enter the SiL-3114 (Silicon Image Controller) Bios,

it shows the 4 drives under Physical Drive but under Logical Drive it says "Invalid Raid drive".

If I click "Create Raid set it comes back with "Not enough single drives to create Raid set".

If I select ?Resolve Conflicts?, it says no conflicts exist.

So now I purchased 2 additional Wd 250GB Drives identical to the other 4.

In addition maybe for troubleshooting, I have another computer that can run 2 drive raid sets.

I am not sure which direction I want to proceed to recover either my disk array or my files

without causing more damage to the posibility of recovering my files!

Please advise, thank-you.

Have you checked the Asus Bios to see that the Silicon Image Raid is activated - Asus boards have that 'Crash Free' feature where, under static shock and other conditions, they reset to defaults.

I just got a computer for free, a Dell Studio 1555. When I got it, it would try to boot, then come to a screen that said that bootmgr.exe was missing. Sometimes I got a message that said something like mpio.sys was corrupted or missing. I have a Win 7 disk, so I put it in and tried to repair the installation. Each time I ran it, it said that the repair had failed. I tried to reinstall windows 7, and It made it to the first restart in the process. It showed the "Starting Windows" screen, but the colors of the windows logo never appeared, then I got the missing bootmgr screen. I decided to install Ubuntu and see if that worked, and it did (I installed it alongside the Windows installation). It was Ubuntu 10.04. I thought, "OK, so i'll just use this as a Linux machine"...and I decided to go back and reinstall so that I could use the entire hard drive. It never worked correctly again. Each subsequent time that I installed Ubuntu, I was told something along the lines of "Gnome Power Manager did not install correctly" and got a slow and choppy Ubuntu installation. Tried to install 11.10, and it failed completely. I opened the Ubuntu live from my usb drive, and opened the disk utility. I now cannot format, reformat, partition, or delete partitions on the drive. Is all of this just a case of a hard drive on its last legs, or is there something else going on here?
Thanks in advance for any help.

A:Bootmgr.exe missing... mpio.sys missing or corrupted. Unable to boot

You should try and use the bootable Partition Wizard CD. It should show you something similar to the Windows Disk Management tool. If it works, you should be able to see all partitions, shrink them, deete them, extend them, format them etc.
Partition Wizard : Use the Bootable CD

If you haven't already, also try running a Startup Repair using the following tutorial.
Startup Repair

If you can't format anything, your last shot may be using Darik's Boot And Nuke (DBAN). This can be put on a USB which when booted, completely wipes every hard drive recognised. So be sure to remove any other hard disk device or drive.

Hi..trying to salvage this mess. Dell Laptop PP05XB-Windows XP

Trying to fix computer for friend....

She has several Trojans, Vundo, countless others.....infested!

Norton detected 3, fixed them, rebooted and received the prompt for corrupt hal.dll, windows wont boot.

Had an XP upgrade cd..didnt work obviously...came across full version of XP professional..recognizes
partitions but wont repair due to no password known....tried everything..she doesnt recall setting up a Master

Bios works fine, In fact, no password has been setup, Bios tells me this. Can get to F8 options but it all leads me back to the corrupt dll message.

Ive put in a message to her for her OEM disc....will this make a difference? Will I still get the prompt for a password?

Any help would be appreciated!


A:Missing dll file and unable to boot

Password requests depend on the system involved, the CDs used, and user intent.http://www.microsoft.com/genuine/ProgramIn...8d-a541ba3aaba9If one has a Microsoft Genuine Windows XP install CD...a user is prompted for a password: a. When such has been implemented by the owner. b. When attempting to access the Recovery Console from that CD. In most cases, this prompt has nothing to do with implemtation of an actual password...and can be overcome by just hitting Enter, moving to the command prompt for RC commands.BIOS passwords have nothing to do with installing XP or Microsoft. Such (BIOS passwords) are implemented by the manufacturer/seller to enable restricted access to that particular system.Many laptops come with a very strong BIOS password capability that locks up the hardware and makes the laptop completely unusable. This is the password that has to be entered before the operating system loads, usually on a black screen a few seconds after the laptop is started.Of course BIOS password can be set on a PC too, but there it is stored together with the other BIOS settings - date, time, hard disk size, etc.!However, most laptops store the BIOS password in a special chip, sometimes even hidden under the CPU, that is not affected when the rest of the BIOS settings are reset. This makes the removal of a BIOS password on a laptop almost impossible. The only option in most cases is to replace the chip which is quite expensive and risky procedure and, of course, not suppor... Read more

HI There

XP based laptop
Fuji lifebook e2000

When windows tries to start I get Hal.dll is missing or corrupt now I have tried the normal steps and spent ages on google and ms knowledge base

I get to repair console and when the c: drive comes up I get the specified drive is not valid or there is no disk in the drive so it just shows as C: and not c:\windows, I dont even get asked which installtion I want to repair etc

Using map the \device\harddrive0\partition1 shows as ?

Same happens in diskpart

Therefore I cannot expand the hal file from the disk and then do the fixboot steps

I get the same error each time I try a command chkdsk /r gives the specified drive is not valid or there is no disk in the drive error and so on and so on

The laptop belongs to a friend so I am reluctant to format and reinstall as he is on holiday and I cannot get it touch with him

When I go through to do a repair install it shows partitions C and D and sizes but when I select the partition I get no option then to repair as setup does to detect the windows installation.

I even started the machine with a xp live disk and it comes on however no HDD is shown

Any advice is welcome as I am now stuck

Thanks in advance

A:Unable to boot xp - Hal.dll missing or corrupt

Hello marty584

I`m afraid these symptoms usually mean a clean reinstall of XP at the least.
If that does not work run the manufacturers diagnostics on the drive


If you don't know the make of hard drive Hitachi Drive Fitness Test will work with any make.

The Hitachi 3rd download is for a bootable CD

These files need to be burned as an ISO file using a program like Imgburn

Start ImgBurn. You will see the the main programme window and a log.
In the main programme window >> click "Write image file to disc".

New window: Make sure ImgBurn has found your CD/DVD burner (Destination).
Then click the "Browse for a file" icon.

Another window will open >> find and select the ISO image you want to burn >> click Open.

Back at the main programme window. Click "Write".

Configure your PC to boot from CD if it isn't already set up that way. You may need to enter the BIOS to configure the PC to boot from the CD.
Set the boot order to
floppy (if present)
Hard disk

Put the CD in the drive and reboot. It should run then.

Another option is to make an Ultimate Boot CD for Windows.

It is not difficult to do. The instructions walk you through it.
This will boot you into your system and has lots of tools on it too.

I've been wreckless with combofix, and now am unable to boot the XP OS.

My girlfriend had some issues with her Toshiba laptop freezing up. To make a long story short, I've somehow managed to corrupt her XP operating system and the Hard Drive now appears unpartitioned. Currently, if I boot the computer I immediately receive the following message:
"NTLDR is missing
Press any key to restart"

I now realize that I should have turned here first, as I am sure I have made things worse, and the data is now perhaps unrecoverable. I am in over my head and need to know what to do with the computer now. The computer will boot with the Windows XP CD (I had to change the boot order in the bios).
When the computer was handed to me, it would freeze each time after an error would appear regarding the built in fingerprint reader. The error displayed a message, as best I can remember it, "W32: err wstd 1702." This error would pop up after random seemingly intervals, but usually within a few minutes of booting up into Windows. My girlfriend had already run malwarebytes, and the log I found showed that two "trojan.dropper" file infections were found and deleted. I ran an additional scan in safemode, and it found another infection in one of the restore points. Otherwise, the system appeared clean, but continued to freeze up. I tried disabling the fingerprint hardware, but this did not prevent the above error from occurring. Nothing in event viewer appeared... Read more

I'm having some serious trouble with Win 7. I was trying to reclaim some unallocated space on the drive and in the process seem to have lost boot manager, so it won't load Windows.

If I put the disc in, it's not able to automatically able to repair because it says the repair disc I'm using is not compatible with the OS I have installed. This is the same disc I used to install Win 7 in the first place. Tried using cmd prompt to reload boot manager manually,and it completes the operation successfully but still says bootmgr is missing at start up.

What's scaring me is that if I try to just install Win 7 again (onto the unallocated space), the hard drive just turns off and the hdd light comes on solid. This is when I choose 'Install Now' from the opening screen before selecting partitions etc. I'm typing this post from a spare hdd. The only thing I can think off at this point is the get an enclosure and recover my files; then wipe the hdd in question and reinstall Win 7.

I would really appreciate any help anyone can give to avoid that route though.


A:Boot Mgr missing and unable to repair

Boot from the Win7 DVD Repair console, press Shift F10 to open a command line to mark Win7 partition Active using DISKPART: Partition - Mark as Active

Now boot back into Repair console to run Startup Repair up to 3 separate times with reboots until Win7 starts, which it should do if it is marked Active and not irreparable: Startup Repair - Run 3 Separate Times

If it won't start, boot back into Command Line and try to jump start the Repair by typing:

bootrec.exe /fixmbr
bootrec/exe /fixboot

Then try running Startup Repair X3.

You can copy files out of unbootable Win7 using DVD and this method: Copy & Paste - in Windows Recovery Console

If forced to reinstall, wipe the HD first as you likely have old code from a previous OS on there which needs overwriting with at least one set of zeroes: SSD / HDD : Optimize for Windows Reinstallation

I have a Gateway PC running Windows 7 Home Premium (64 bit) and last week it failed to boot. Also unable to boot to Safe Mode. Tried running Startup Repair and booting from last known good configuration but that didn't help. Also tried CHKDSK but didn't seem to find anything. 
Next step was to try the Farbar Recovery Scan Tool, which said that the winsrv.dll was missing from C:\Windows\System32 folder.
I retrieved the latest version of winsrv.dll I could find from the C:\Windows\WinSxS folder and copied that into the System32 folder but am now getting a BSOD with message:
"STOP: c0000142 {DLL initialization failed} Intialization of the dynamic link library winsrv failed. The process is terminating abnormally"
Have re-tried Startup Repair and ran sfc /scannow from the command prompt to see if that helps but no luck. 
Any ideas where to go from here?

Originally i thought something was wrong with the boot but now i think it may or may not be. All help is highly appreciated.

A:Unable to boot, invalid system disk. replace disk and press any key to continue

Few, if any, downloadable copies of WinXP are legal. The 'Invalid System Disk' error message is the tip off.

You'll need to buy a copy from an authorized source. There is no way to trick the system into recognizing an illegal copy of Windows.

If so, follow the steps in the Perfect Reinstall link in my signature box below to try correctly reinstalling.

You can cut and paste the questions below on your New Thread to easily give the answers:

Current Operating System, pre-install ? Do you have a single OS on your computer, are you planning on multi-booting with this installation? Single OS (XP Pro SP3), and yes I want to dual boot.

Current Hardware ? How many internal hard drives (HD) are connected to your system? 3
? Are they IDE or SATA? 2 IDE (D: Maxtor 60, G: Maxtor 80) and 1 SATA (C: WD 300). C is a newer drive, used to be G when it was first installed. G used to C. WD had some type of program that could copy drives, so I copied the old C to the old G, that flipped their drive letters. Since then I get the aforementioned dual boot screen for two versions of the same OS.

I still have windows 7 installed, and I have full access to ubuntu.

I tried copying a fresh version of the file to \Windows\System32. No dice. I tried renaming it all uppercase and then all lowercase. Nothing. I put a copy in the root directory. No effect. I tried everything I could think of, but nothing worked.

Then--doh!--I stopped thrashing and did what I should have done initially: I dug into the Microsoft Knowledge Base and learned about XP's built-in Rebuild command. It can often easily fix "Missing HAL" and similar problems in just a minute or two. If you know about this command and how to use it, you can potentially save yourself hours and hours of manually reinstalling or rebuilding a failed operating system.

Hi, I am starting a new post on this subject because the "solution" posted in prior years (2014-16) does not work for my computer. The solution recommended switching the boot mode from "UEFI" to "legacy support"On my device this requires switching the "sata controller mode" to "AHCI" from "Intel RST Prem" -- my computer will not start in this mode. I've performed every system and bios update i could find.  Can anyone help? Many thanks,Suzanne

Hi phelly , 
Welcome to the Community Forums. 
The IT guys may have also checked the BIOS if the SSD is being detected. 
Usually reseating the M.2 SSD (page 36) from its location and placing it back assuring that contacts are ok can help as well as loading the BIOS defaults then restart. 
If you would be having the same issue , I would suggest to call in technical support or have a representative in UK start a repair ticket for you and get their recommendation. 
Update us how it best work for you.

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.

After deleting the partition on which Ubuntu was installed and enlarging the windows partition to fill the old space at the same time( stupid I know), I am unable to boot to Windows 7.

Is this terminal and have I lost all data on that pc? Will taking it to a pc wizard do any good?

A:Unable to find boot drive insert boot disk

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.

Hey there all,

Earlier, about an hour ago, I left to go job searching, and left my computer in hibernate mode so I could bring it back up as soon as I got back. When I tapped keys on the keyboard, the computer powered up as usual, but it brought up the BSoD, stating it was missing files.

Prior to receiving this error, everything was working fine. I even set it to hibernate mode during the night, and it powered on this morning without any problems. I dunno if it's the multimedia keyboard I'm using or what that caused it.

I don't have an installation disc (since I bought it from Fry's Electronics about a year ago with 8 pre-installed), and neither do I have a recovery disc (since I didn't know how to make one.)

Computer info: Windows 8 x64
Manufacturer: ASUS

I'm just wondering mainly how to fix this, i.e: how to fix the missing boot files, and how to do it without causing any data loss from either of my hard drives.

I have a HP notebook(XP Home) that stop booting windows a while back after it crashed during an SP2 install. It does not boot from any mode in the advanced menu(safe, command, last known good config, etc.). I can't boot from my Knoppix disk because it says that there is a checksum error, even though I can boot from the same Knoppix disk on my desktop fine. Mind you this laptop has only a CDRW/DVDROM combo drive, no floppy or zip. I finally found my XP setup cd recently and tried to boot from it to perform a repair or access the recovery console, if it's possible. The problem is it won't even boot from that. It gives me the "NTLDR missing, press ctrl+alt+delete to restart" message when I boot from the Win Xp setup cd. I have read about some of the solutions involving a floppy boot disk, but I only have a cdrw/dvdrom combo drive to work with. Anybody have any ideas how to resolve this so I can boot the setup disk and run a repair?

A:HP Notebook/XP/Will not boot in any mode/tried to to boot from XP disk=NTLDR missing

Make sure your boot sequence in the BIOS is set to boot from the cdrw/dvdrom drive first. Place in your disc and reboot.
Normally tapping the Delete key at boot will take you into the BIOS

This in reference to when windows xp will not boot, and when trying to boot, it brings you to a text screen saying... Windows will not load. File HAL32.dll cannot be found or is corrupted. And this process lists several files that windows says are missing.

How can one go about using the command line repair interface to repair these files? Can someone provide me a link to the process on how to do this in such a scenario. The reason I want to do this is so I dont have to reformat (or at least try not to) if I dont have to. I know quite a few techs out there that just dont mess with it. But I would really like to know how to do this.

Any suggestions and or experiences would be great.

I have tried everything !! everything!. I've been trying for days and i hate asking for help, but i just cant get it to work!

I have an msi wind, and it runs Xp, but i tried dual booting osx and everything goes fine. Though now i cannot access Win Xp cause it says im missing the hal.dll.

So there is something wrong with the boot.ini file.

What can i do?

Things i have tried
1) Modify the boot.ini from osx but the file is protected!
2) Use the recovery disk but i dont have a cd drive! and getting a usb is not an option.
3) Safe mod or command promt mode did not work
4) Tried installing Ubuntu onto an external hard disk so i can modify the partitions, and i got ubuntu on my ext hdd now but when i in bios tell the pc to boot from usb it just have that flashing cursor and nothing happens!.

Seriously, for two days i have googled everything and been to msi wind forums, but i cant find a solution.. Im not that kind of guy who does not try before he asks!

How can i make that Ext Hdd bootable?? Or can i some how get Recovery console to run from Usb flash drive??

I need my msi wind for school, so i really could use some help. Thanks in advance, if you need more info please tell.

A:[SOLVED] Cannot access Win Xp (dual boot failed) hal.dll missing, cannot boot from Ex

I don't think there is anything you can do unless you boot from an optical disc. That means getting an external optical drive. But google for how to make an ASUS EEE PC boot from a USB flash drive and see if that procedure will work for you with the Msi Wind also.

Hi everyone, since two months I have the issue with my boot device. It looks like my laptop suddenly hangs up, afterward, it is shown shortly a screen "It is a problem ;(", my PC restarts and I get the caption "default boot device missing or failed". If I go to BIAS/Boot menu I see my boot device (Samsung....) and boot manager as well there. I already have used the Lenovo Solution Center for hardware scan, but no hardware problem was found. I have also reinstalled my Windows twice. This laptop is still under warranty and I have already sent in Lenovo service center because of this problem, but that brought nothing; I have got it back and after few weeks still have this problem. Do you have some ideas what could I do else?

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.

I've tried performing a chkdsk function which was not able to fix the problem.

I've tried using bootrec. one of the functions showed that I had 0 windows installed. looking up and following the /rebuildbcd function from the microsoft site I fixed that problem so that it shows ... Read more

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.
I've also tried chckdsk and used chkdsk /fix. this did report problems on the C drive and the /f run did say it corrected things on the ssd but still i am unable to load or boot via safe/system recover or ev... Read more

The problem about which I'm posting is with a Gateway 820gm XP Media Center 2005 PC. Some background information on the state of this PC before the incident:The system's main hard drive died last week (no mystery, I dropped the friggin' thing), so I recently put in a new HD and reinstalled the operating system. After many hours downloading all of the Windows Service Packs and other updates (the most recent of which was the Office 2007 Compatibility Pack), the PC was finally back up and running, and was doing so quite smoothly.I typically leave my PC on overnight and use an alarm clock program to wake myself up. When I awoke to my cell phone alarm instead, I noticed the usual signs of a power outage. (12:00 blink on microwave, stereo, etc.) Naturally, I switched on my computer. Then...The computer began to boot as normal and prompted me for the boot password, which it took as expected. It then continued to the usual Windows splash screen that precedes the Welcome Screen or the Desktop (depending on user settings). However, after the Windows splash screen, my monitors remained blank. After several minutes and, wondering if this was just a display failure, I began to take actions that would normally result in sound output (activating Windows Media Center, keying Shift 5 times for the StickyKeys beep, etc.) No result. I tested the "sleep" button on my keyboard which also yielded no result. I then did a hard reboot. Once more, I entered the boot pa... Read more
