Boot Corrupt And Unreadable, Repair/re-install Of Windows Fails
Nov 26, 2012
It's my daughter's computer. A little e-Machine, 250G HD, Windows 7 32-bit on it. Out of nowhere her computer wouldn't boot up. I can get it to try to boot using the Windows disk, it gets so far, and then the repair fails saying:
The file or directory C:/Boot is corrupt and unreadable. Please run chkdsk utility.
I try to re-install. she had backed up everything on my external just days before. It gets near the end, and then the same error comes up. I cannot get into anything else. Nothing else will load. I don't even know how I can run chkdsk. Unfortunately the computer is about three years old and she can't remember the specifics except there is only one HD in it. She had no internet at her place so it's not because she suddenly installed something. She was using it to watch movies and listen to music mostly. I'm at wits' end, can't figure it out.

1. Same computer in my signature/specs except for the optical drive.
2. Hardware passes Windows 7 compatibility test.
3. The install DVD can be read properly. Creating an ISO image of it works perfectly. No read errors on the disk itself.
4. The optical drive is practically brand new, the cable is brand new, never had any I/O errors using this drive.
5. RAM passes MS memory testing 6 times. 0 errors.
6. Windows 7 Ultimate install fails at the same point, during file unpacking, 3 times. Says files are missing or corrupt.
The install disk was created at home from an ISO download, student licensed Windows 7 Ultimate, 32 bit but I don't think that really matters. See #3.Is there anything else left to look at? Any ideas why this won't work?

Then i tried to system restore which failed also , but the catch is my system boots fine from Safe Mode.. what to do from Safe Mode to return my boot up back to normal?

I have a dual boot machine, Windows 7 Pro 64-bit and Kubuntu 9.10. Everybody was getting along just fine.
Today I booted from Windows, no problem; booted Kubuntu, no problem; then later rebooted to Windows. I now get a message that my Program Files (x86) folder is corrupt and unreadable. [While in Kubuntu I did nothing other than look at the list of files using Kubuntu. No file was opened or modified.]
- I tried dropping to a command prompt to run chkdsk (as recommended by the error screen) but cmd is corrupted
- So I booted off the Windows 7 disk and was able to run chkdsk - no problems found (with the /f and later the /r switches)
When Windows 7 opens, all my 32-bit programs are unusable, and I can't explore the Program Files (x86) folder. Properties lists it as 0 bytes. However, when I browse the folder from a Kubuntu boot, everything seems normal and is accessible.
I (gently) used some Kubuntu ntfs tools (such as ntfsfix to flag the volume as dirty so Windows would check/repair the volume on boot) but got nowhere. [I have no idea if this is useful, but I included the ntfsinfo output from both my Program Files and Program Files (x86) folders.]

I started the StartUp Repair again and it has this error: Code: Root cause found:
Boot manager is missing or corrupt.
Repair action: File repair.
Result: Failed. Error code = 0x15
time taken = 0 ms
What does this mean?

I'm in desperate need to recover things from my corrupted D drive. When I click on it, it says D: is not accessible. The disk structure is corrupted and unreadable.When I restart it always does chkdsk for that drive, but it can't repair the corrupt master file table, and it's the same result where the drive is unreadable. I used the Getdata recover my files software to recover the drive. It didn't find the things I desperately need, and I noticed a bunch of files it recovered is now corrupt.The most important thing I need to recover is a windows movie maker project that I've spent hours upon hours upon hours on for a music video. I so desperately need that .mswmm file. This software found just about all of my windows movie maker projects except that one, just my luck.
The second most important thing I need is my Adobe Audition session files along with the wav's for the sessions. I have a new computer I should be getting today, and my friend will be over in 2 days. I need to figure something out quickly cause he will need to format the drive which will make it lose everything. He is pretty sure that the drive will be unreadable on his laptop which he's bringing over.It recovered 2 936gb files and a 465 gb file with no file extensions that were labeled $BadClus~$Bad_1 $BadClus~$Bad_3

I've got a corrupt file on my TomTom ONE Third Edition. TomTom support has been unhelpful, and Google has let me down for the last 2 hours. I've tried programs like ChkDsk, Move On Boot, Unlocker, and FileASSASSIN.
I am running Windows 7 Ultimate, and the file that needs to be deleted is ttsystem.

Ok so after years of running XP, I finally got an external HDD to back all my crap on and Windows 7 Ultimate. I backed up all my stuff, ran the win7 DVD through start up, reformated my hard drive, installed windows 7.
It installed fine, rebooted a couple of times through the install, finishes, and logs me to the desktop. Its all working fine, I can use the net etc. I shut it down to restart it, and it doesn't start back up. It gets to the bios window where it decides to start off the dvd or hdd, just prior to where it should normally change to the 'windows is loading' screen, and just sits there, blinking and doing nothing.
I've done three installs, I took out the hard drive, reformated it with another computer, made sure it had a ntfs file system, everything, it's working fine. But every single time I install windows 7, It logs me into the desktop for the first time, I can do everything fine, but then if I Shutdown or restart, it hangs on the screen prior to windows loading. I can't even choose a boot option.
I've seen some ideas on other forums, pulling the power out, resetting the bios/cmos, changing boot sequence, unplugging all non-essential hardware.. nothing. It's like as soon as I install windows 7 my hard drive isn't there anymore.
Specs:
Abit AX78 - Latest BIOS version
AMD 9950 quad core 2.6
4GB DDR2-800
ATi HD 5870
Western Digital 500GB

I was originally dual booting XP and Ubuntu on my main 240gb drive. I decided to give 7 a shot and in doing so wiped my ubuntu install, formatted a nice 50gb ntfs partition for 7 and installed it fine. However now when trying to boot into my "Previous Windows Installation" I'm getting a blank screen. I've tried using the XP recovery console from the disk to restore the bootmgr however chkdsk fails. I think somehow the partition table got rearranged during my install, and 7 didn't fix it for me. I have no idea what to do anymore since 7 won't allow me to change the partition value in my boot.ini file. I have a feeling that's all i need to do. I'm getting "Access is denied" on bootmgr and boot.ini in my XP home folder when accessing from Windows 7..

I was having trouble migrating my OS to a new ssd and received the "Bootmgr is corrupt system can not boot" screen repeatedly after restoring from system image, kept happening so I just decided on a fresh install. Install went well and was fully functional (eg drivers and devices) yet when restarting after installing microsoft office, I got the "Bootmgr is corrupt system cannot boot" appeared and now cannot get the pc past this point no matter how many reboots.

Clean installing Windows 7 x86 is no problem. But
1) upgrading Vista x86 to Windows 7 x86 fails and automatically rolls back to Vista, and
2) attempt to clean install Windows 7 x64 results in BSOD when rebooting to finalize the process.
Any suggestion would be appreciated.

I have just bought 7 Profession 64-bit and upgrade from my Vista Home Prem install. Everytime i install graphics drivers it fails on re-boot.
As far as i can see the drivers install fine (newest ones on nvidia site 195.55 and 186.whatever) then i restart, it loads the "starting windows" page, goes through that fine, but when it tries to go on it just crashes forcing me to use system restore to remove the nvidia drivers so i can run it again.

I have downloaded windows 7 home premium upgrade ISO from the microsoft store. The burned the iso to disk using the image burner in windows.
My problem is that the disk will boot, and a "windows is loading" screen appears which only takes a minute. Then a windows background appears on screen with a cursor. That is all. No setup at all. What might be wrong here. I would like to make a bootable disk that works.
I can run setup from an OS, but that is not what I want to be able to do.

I've just built my own computer with a friend and we installed windows 7 and it worked fine for 3 days. Then it started to not respond. Restarted the computer and it wouldn't start up again, came up with a bunch of errors. So I reformatted and it says "windowssystem32driverwdf0100.sdf is corrupt or missing." I've tried system repair but it won't work. It won't open command prompt or anything.

I have run sfc/scannow in win 7, and have followed instructions to run sfc at boot in command prompt, but nothing has solved the errors. i have saved the file sfcdetails.txt to desktop, and have extracted only the problematic parts and saved it in another file problems.txt kindly check the file, as i have attached it here.
all the files are either .inf or with .nlp extensions.windows is running fine. but i want to get rid of the problems before they become a serious issue. I have a pre-installed OEM version of win 7 basic SP 1, and i have a HP G6-1117TX laptop. There is a drive named "System", which is the active and boot-able partition, and is not the same drive where windows is installed.

I recently took my pc in for repair of the raid drive. The service center used a software which allowed them to change my password, so that they could access the pc. however I believe it damaged my profile because now, I can not change the password from password and outlook no longer remembers any of my email passwords, I must reenter them all each time I run outlook. I am trying to avoid creating a new profile.I am running Windows 7 Professional 64x with a mirrored 2TB drive. Simple peer to peer workgroup

I have a Sony Vaio VGN-NW270F 15" laptop with Windows 7 (64 bit) Home Premium. 320 gb. Oh i'm also out of warranty.Computer always freezes at the point where it says "starting windows" and stays frozen. I even left it for alone for 24 hrs and it stayed on that screen.
Things I've tried:
1. I used safe mode to repair windows = just restarted in normal mode and froze at "windows is starting"
2. Used safe mode to restore to earlier point = could not to restore message
3. Created repair disc from another Vaio win 64 = froze at "windows is starting"
4. Used registry clean and malware bytes in safe mode = malware bytes found nothing & reg clean did nothing
5. Fresh install of windows 7 = windows bar loaded then froze at "windows is starting"
6. Reformatted hard drive & performed fresh install = windows bar loaded 7 froze at same point
7. Bought new Western digital 320 gb SATA Hard drive & tried install of win 7= same results

I am running Windows 7 64 bit Ultimate on two PCs on my home network. I went to use one yesterday and was presented with a black screen. I rebooted the PC hoping that would solve my issue and was presented with the following error message while trying to reboot:
Windows failed to start. A recent hardware or software change might be the cause.
File: BOOTBCD
Status: 0xc000000d
Info: An error occurred while attempting to read the boot configuration data
I checked my other PC and saw that it had been updated with several Windows patches yesterday. I'm guessing that the broken PC had an issue installing or rebooting from one of the patches. I ran the repair utility on the windows 7 dvd as instructed by the error message. It was unable to find a previous installation of windows with an error box saying: The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility.
I tried the auto repair anyway, which appears to be working until the end when it gives me the "The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility" error again. Then it says it can't save the fixes and says it can't be repaired. When I check the details it says I need to "repair offline" and that it cannot find an OS installed.
In my searches for an answer, I read about rebuilding the BCD through the command prompt. I ran the following commands:
BOOTREC /FIXMBR - said it was successful
BOOTREC /FIXBOOT - said it was successful
BOOTREC /REBUILDBCD - failed saying The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility
I ran chkdsk and got no errors. I only have one hard drive, but when I go to a command prompt (from the repair section on the Windows 7 Install disk) it defaults to D:. I checked C: and it appears to be making the reserved system space drive C:, which would explain why I can't find a windows install on it. Worst case, If I just go down the path of re-installing windows without formatting the drive, will it pickup my old settings?
Here is what system info I could get (from the BIOS startup diagnostics):
Main Processor: AMD Athalon 64x2 Dual Core Processor 3800+
Memory Testing: 2030592K +64M shared memory
Memory Information: DDR2 533 Dual Channel, 128 bit
CPU L2 cache size: 512K x 2

This maching was turned off and unplugged while owner went on vacation.On return it just goes to the auto repair parocess every power up.Went to DOS prompt and the drive with windows on it was given the letter D, the system partition was given C.I tried bootrec /rebuildbcd and /fixboot to no avail. Then I assigned the windows partition to C and the system partition to D and tried again to no avail.I have removed this drive and scanned it on another PC as a secondary drive and found nothing other than cookies with Malwarebytes, SuperAntiSpyware as well as nortons. I also looked for rootkit with TDSSkiller. After renaming cbs.log I looked in D;windowslogscbs after doing a sfc /scannow process for the repair log and there was none created. I looked on the system boot drive "C" but of course there was no windows folder so I created a windows/logs/cbs folder to see it it might be created there, it wasn't.This appears to not be due to a bug but maybe a shutdown while it was in hibernation or something like that.

I'm trying to repair my Windows 7 ultimate installation. When the procedure reaches its final step, I keep getting a message that the repair failed and that my system is being restored to its former state.Is there a way to depict the cause of this failure? Does Windows 7 keep a log? Is it accessible?Do you know of any other method to overcome this obstacle?

After I tried to make a dual boot with Ubuntu and Windows 7 Ultimate (64-bit), Windows now does not boot. I have tried to reinstall and repair the HDD but the disc fails to recognize my HDD (Western Digital Scorpio Black 500 GB). My HDD is Basic, has 3 primary partitions and 1 extended (3 logical). Ubuntu 11.10 can boot fine.

When I bought the kit and built my new computer last year, I noticed that Windows 7 didn't like being turned off for any period of time over 5 minutes. Anytime longer and it would BSOD on me. Sometimes it gave me a full coded screen, other times notSometimes it would take me to a repair screen, sometimes not. Sometimes it would just boot up (I liked those times best) Every so often, I would have to system restore. It was annoying, but I could not find a fix, and when I did diagnostics on the disk, I was never given any errors on for the Hard drive or anything. Fast forward to a month ago when My monitor up and died on me. I had to send it to be repaired. This meant that I had to turn the hard drive off. I hooked it up today and it decided not to work. I tried system restore and the system repair and they have been useless. I contineu to get the following message upon every boot up now[CODE]

I have a Toshiba Satellite C655-S5132 that just shut down & now will not boot Windows 7. Just goes to black screen w/blinking cursor then goes to 'startup repair' (which I'm postiive this is a virus of somekind) & will not allow me to do anything. Just repeats itself. I downloaded Windows 7 repair to a CD-R, chgd BIOS settings to CD/DVD to boot first, saved changes, and will NOT pull/boot up from disc. I've tried 2diff repair discs, both do not work. 'F8' does not do anything for me, not able to get to 'safe mode'. Computer is only 2yrs old.

I was getting notification bubbles in W7 about many of my .exe files being corrupt, including chrome.exe and a few other programs. The notifications recommended that I run Chkdsk, so I went to the C: properties and chose Disk Cleanup, or whatever Chkdsk is called in the menu, I forget at the moment. Well, when I did that, I got yet another notification, this time saying that Chkdsk.exe is corrupt, and recommending that I run Chkdsk (lol). Well, I apparently chose to schedule Chkdsk to run on next startup. But after I shut down to let it run I booted up and after my Dell screen I get....nothing.
Just a blinking horizontal bar, looks like that little input cursor flipped on its side, in the top left corner. I'm running Ubuntu 11.10 on a USB flash drive at the moment, what can I do from here? Until this happened I've never used a Linux OS before so I'm not very savvy with it yet, but when I view my partitions on here (500GB HDD) I see that 451GB is Unknown, in a partition manager there is a red flag notification saying that I have bad sectors, which I already knew. I've heard a lot about running a program called ntfsprogs, but I can't find it. Is there any way to recover my Windows 7 boot without losing any of my data on there?

It was doing this once before, but this time there is no BSOD. My system is biostar TH55b hd mobo, Asus ATI 5450 HD Graphics, 4 gigs ram, and several hundred gigs oh hd space. The description of the issue is that my pc freezes daily without any specific messages. Wish I could give you a better desription. This is a fresh reinstall of the os. Also there isn't any bluescreen hence there's no dump file, atleast that I know of.

I have an OLD computer with a 2.4 GHz processor and 1 GB ram, running XP 32 bit. I wanted to upgrade to Windows 7, So I tried to install 32 bit windows 7, knowing my computer couldn't handle 64 bit. However, at the end, it simply told me "Installation Failed" and reverted to XP, with all my files. I tried multiple times, then I tried installing 64 bit windows 7, and surprisingly, it worked. However, it is laggy beyond belief, so I tried installing 32 bit again. Again the installation failed. Now I'm thinking of reverting BACK to XP.
