Corrupt Boot Sector
Apr 1, 2008
Vista SP1, 500GB disk, 3 partitions: system, data & other Used Paragon Parition Manager 8.5 to resize partitions (shrink system, expand data), rebooted and now can't boot. In System Recovery options get "Operating System: Unknown on (Unknown) Local disk". Open a command prompt and can only see the data partition. If I run Startup Repair, I get the following output:
Problem Event Name:StartupRepairV2
Problem Signature 01:System Disk
Problem Signature 02:6.0.6000.16386.0.0.0.0
Problem Signature 03:1

Problem Signature 09:FixBootSector
Problem Signature 10:1168
OS Version:6.0.6000.2.0.0.256.1
Locale ID:1033
Looking at http://support.microsoft.com/kb/927392/en-us, if I try 'bootrec /scanos' I get 'Total Identified Windows Installations: 0'. Should I try the /FixMBR or /Fixboot options? If not, what else can I try?

I've been trying to install First Defense-ISR Rescue on this computer and it won't install, it gets a -11 code and quits. The code means This means the boot sector is not a standard Windows boot sector. I have Windows Vista Home Premium 64 bit. My question is, if I remove the Recovery Partition D will this change the boot sector. I have factory backup DVD's and made my own DVD's, plus I have a TI image of the drive so I'm OK in that department.

I had a perfectly good dual boot Vista and XP system until I installed Windows 7 RC. I installed Windows 7 RC to a new partition on the Vista (slave drive) with XP installed on the master drive. Vista and Windows 7 booted okay but despite there being 3 options in the boot menu - Earlier Version of Windows (XP), Vista and Windows 7, XP would not (and will not) boot. The error message when selecting XP from the boot menu was that the boot.ini file is invalid; I then get a message saying that the system32hal.dll is corrupt or missing.
I used EasyBCD to restore a backup of the previous Vista boot loader which worked with XP. Windows 7 disappeared from the boot options but I still cannot boot in to XP - I get the same error message (boot.ini and hal.dll). I can boot in to Vista. EasyBCD tells me that there are 2 entries in the Vista bootloader:.....

I have a toshiba laptop. It is running Vista Home Premium 32bit. I did a dual boot and installed windows 7 premium 32bit on a second partition. It installed fine but I ran into driver problems as well as a corrupt disc error. I decided to go back to vista and formatted the 7 partition. When I restart my pc I still get the option to boot into 7. How do I remove this option?

wanting to add XP as an addl os using dual boot. I managed to get XP installed along with Vista home basic, but apparently messed up the boot sequence. I can can boot Vista, but not XP ...error window says file: tldr status: 0xc000000f the selected entry could not be loaded as the application is missing or corrupt
I used Vista Boot Pro 3.3 to set the booting. If I set VPR to install legacy booting, it will boot up with XP (no dual boot choice), but not Vista. If I select use legacy boot for selected drive E (XP), it says it is set, but a reboot brings me back to the error above. If I use VBR and set booting for Vista, only Vista boots. I have tried using the XP CD to do a repair install, but it asks for a password, which I never have set. When I hit enter, it keeps asking for password, then times out after the 3rd failed attempt. I only have the Vista backup CD (2 actually) from Dell, not an install Vista CD. My hd is a SATA, and I see that may be a problem by reading other threads here, but I have no floppy drive, only the cd/dvd. If I need another file which may be missing, can someone point me in the right direction ?

I use a 160 Gb Seagate Momentus 7200.2 SATA HDD (ST9160823AS) in my Asus F3Sa notebook and I have the following problem : For security reasons, the encryption software I want to use check if the last sector of my HDD is readable before installing. As it says there is a problem, I wanted to check by myself using the following command : dd if=[harddrive] of=[output file] bs=512 count=1 skip=[total guaranteed sectors - 1]
Under Vista (see dd for Windows on Wikipedia), it returns an empty file, meaning that the last sector is unreadable. Under Linux, the very same command returns data without any problem. The last sector is perfectly readable. Thinking to a driver problem, I wrote to Intel (ICH8M chip) and they replied "We understand your concern but the problem you described is directly related to the motherboard or hard drive manufacturer, not chipset software". Very strange as the problem does not exist under Linux with the same hardware.
I wrote to Asus and they told to me to ask Seagate... I asked Seagate and they explained to me the problem seems to be software/driver/OS related. So... Now I'm stuck and I can't install my encryption software. What can I do. Could it be a problem of Windows Vista ? I use the latest computer bios, updated Vista and latest Intel chipset driver. The HDD health has been checked with a dozen of Linux or Windows tools. It's in perfect condition.

Back up stopped working. Got the error message "Cannot find the sector requested.(0x8007001B)". I saw one reply that said to backup to C drive, but this is not an option on the setup page for backup. What next?

I went to turn it on this morning, I just had a black screen showing the following words;
Press F2 to run
Press F11 to boot menu
Auto detecting PRI Master Atapai CDROM.
It then went to reboot and select proper boot device or insert boot media in selected boot device and press a key. I went into the BIOS to change the boot order and inserted my Vista home premium 32bit. I then got windows is loading in files. After a short while I got the black start up screen with Microsoft Corporation but after a few seconds it just froze. Moments later it went to a blue screen with white writing part of which said the following; A PROBLEM HAS BEEN DETECTED AND WINDOWS HAS BEEN SHUT DOWN TO PREVENT DAMAGE TI YOUR COMPUTER.

I turn on my computer and it tells me that my c drive is corrupt and to run chkdsk.
I go into command prompt (right clicking on it to run it as an admin) and run the command sfc /scannow.
It says that it's starting the system scan and that it will take some time, but as it's getting it's "Verification" it stops at 9 percent complete and says that "Windows Resource Protection could not perform the requested operation."
I've also tried going in through computer>right click>properties>tools>error-checking>check now and then clicking both check-boxes >start>schedule disk check and then I've tried restarting, but nothing happened.

I have a problem with my PC with windows updates. When I turn the computer on in the morning it starts installing new updates. this takes about 35 minutes on stage 1 of 3 then it shuts down. When it restarts again I get a tech guys message to say "Your computer was unable to start. Running start-up repair"
At the end of this when I look at the diagnosis it says:
Boot critical file C:
toskrnl.exe is corrupt
Repair Action: File repair
Result! failed error code OxA
Time taken = 4462ms
Repair action: System restore
Result: Completed successfully
Error code = OXO.
This is now happening every time I restart my computer and it takes about an hour. Windows then starts OK until the next time
Do I need to reinstall windows Vista Home Premium??? It was already installed on the PC when I bought it and they did not give me a CD.

I've been having some trouble with my installation of Vista today. It had been running without a hitch for nearly a year. I think the problem started since Windows was taking a long time to shut down, I assumed (wrongly perhaps) that it had frozen, and so I forced it to shutdown by holding the power button for 5 seconds. Another possible cause could be I plugged in a USB joystick (driver conflict?).
When I started my PC back up I noticed things seemed to be running very slowly at times, as if the system was having trouble accessing some files. I scheduled a Disk Check and restarted. It found and fixed some errors, brought me into my desktop, and then a pop up kept appearing in the bottom right tool bar saying '*.exe could not be accessed' and something about a folder named '$Secure'. My browser bookmarks wouldn't load, for example. I restarted again and this time during startup the green loading bar would run its course, and then a black screen and a cursor appeared, rather than the Vista logon screen. I booted off my Vista DVD and ran Startup Repair. It found and fixed some errors but I still have the black screen problem. I also ran another Disk Check, as well as some HDD diagnostic software - it said everything was fine. When I try running Startup Repair again, it tells me it doesn't see any errors and to remove any recently added hardware (I have). I'm stuck at this point. I would like to repair (upgrade) my installation of Vista, but I need to be able to get into a working install in the first place to do that.

I recently partitioned my 500 GB hard disk on my Vista computer into multiple drives in order to keep data files and picture files separate. In doing that I succeeded in
screwing up the folder line-up in my user folder. In spite of many tries I haven't been able to "unscrew" it. There are two main problems:
1. There are now two folders called Pictures (E referring to ther new partition
Both of these folders contain the same subfolders and files. No matter what I try, I cannot delete one of these listings.
2. There is an additional folder called Pictures.
However this folder contains all the music folders and files. When I try to rename this folder to Music, I get the error message:"This action can't be completed because the
folder is open in another program", even though no other programs are running.

My Vista Premium will not run autochk.exe. I ran sfc/ scannow and the cbs log file found autochk.exe corrupt. I tried to copy autochk.exe from another Vista PC to the c:windowssystem 32 folder and it will not let me. I'm running as administrator and click continue when user account control pops up, but it won't copy.

Something has been bothering me a lot in Vista 64 Ultimate SP1. Every now and then, when Windows starts, it says my disk structure is corrupt and I should run chkdsk in order to fix it. When I try to run CHKDSK under Vista, I get a "insufficient disk space to fix master table (MFT)", and CHKDSK aborts. I can't create folders, files, Windows Update fails ...
The good thing is a have a dual boot system and when I choose XP, Windows XP detects that the Vista partition needs chkdsk and this time, chkdsk runs completely and fixes the Vista partition. So I can restart the computer, choose Vista partition again and this time everything will work fine.
Problem is, this is happening too often. Like every day. And it is such a hassle to start Vista, get the error message, restart, choose XP, fix Vista, restart, choose Vista and then have everything normal. Any of you guys have an idea on WHY my disk structure is getting corrupt all the time? My Vista installation is very recent, and I did a full format in the partition before installing it.

LOng story short, I had to restore last night due to what seemed like a video driver problem. I restored, back a couple weeks and it fixed my video issue. It then did the automatic windows updates, including SP1, which I thought was odd, but I went with it. After the download & update the system rebooted...and then it all went downhill. I actually got another error message which I can't recall at the moment, but it was a black screen not a blue.... I then broke out my original windows recovery discs, rebooted and it went directly to the recovery options and screens as I was expecting. The first disc ran fine, backing up files, blah blah.....it said to reboot...and then THIS stuff started.......

I just tried three times to download the Windows 7 .ISO beta through the Download Manager. I only succeeded once and when I finally got it down it seemed there was a corrupt image. Does anybody have a clean link to the image? I'm anxious to try it out in my VirtualBox.

When Vista Home Premium 64 bit boots, an error pops up from the system tray saying that C:Users(username)AppdataRoamingMicrosoftWindowsCookies is corrupt, and suggests to run chkdsk (which did not help). I've tried renaming the folder to see if Vista would recreate a new one, but the same error appears, with the new folder name. I tried to delete the folder, would not delete, gave no reason why. I tried booting into the hidden admin account to delete it, still would not delete. If I try to open the folder, it says the folder is corrupt, it cannot be opened.

My Laptop was taking about 8-9 mins on average to boot. But Runs Great once running. also shut down was 4-5 mins. I tried Defrag, CCleaner Defrag Registry, Registry Cleanup,enable both cpu's at start up,ran Avanquest's System Suite Utilities, Chkdsk/f /r,also sfc /scannow.so reading on some forums, a lot of advice was to update all drivers. So I got Driver Genius Pro 9 by avanquest (Driversoft company when installed)this program found 22 drivers out of date. so I created a restore Point and did a full registry export(backup).next, I let all the drivers completely download, then First, I installed Intel turbo memory drivers,everything was functioning well, so I proceeded to install Intel chipset device software.
3rd was the Nvidia Display Drivers so I made a second Restore point (I had issues in the past with display drivers) So I installed the Nvidia drivers and on reboot I input my password and it says The User Profile Service service failed the logon. User Profile cannot be loaded. I tried to run Restore but it says Disk OS(C) has errors(Windows detected file system corruption on OS(C). you must check the disk for errors before it can be restored. checking disk OS (C) - Some Problems were found and fixed. But at reboot - same issue. so I went to vista forums."Brink" had some great advice I used that I found in a thread, to turn on the "Real" administrator account in safe mode to gain access and I uninstalled the Nvidia drivers under the admin acct. at reboot states corrupt system files (CheckDisk) But when I tried to run driver Genius in admin again to reverse the intel drivers (this shows up as Intel Matrix Storage Manager in Start>Programs) the PC crashed.
I ran CHKDSK /f .NOW I can boot into my acct. but there is NO sound device found, sidebar gadget shows no battery,or battery activity.Also bluetooth Hardware not functioning. The Drivers for bluetooth and sound show "Functioning" in device manager. Someone HELP Please as I spent many many months customizing and lots of money on software that will be lost. It seems to be fixable but HOW?

After two days of trying to recover my vista installation I've got a new version of vista and it it's still telling me i've got missing or corrupt files. Where can get the correct files/ a good recovery disk/ a bootable virus cd (tried bit defender - didn't work). I've read soooo many pages about this and nothing works. Startup repair - doesn't work; complete system recovery - doesn't work; formatting during the vista installation - doesn't work.

Recently I have had three files turn sour on me for no visible reason (corrupt). One of them is a very imporant bit of course work. Im running office 2007 and 32bit vista home. I have been storing the files on a USB stick I thing there may be someing wrong with the usb stick I have now changed it but this dose not solve my problem of the lost files.
I have tried downloading various recovery programs none of which have worked. I have also downloaded open office and that will not open the files either. I don't know where to go from here. If someone can send me back the "energy survey" in working order im willing to send them £5 via PayPal. Only 2 the first person.

when I powered up my Vista I noticed that it was unusually slow and all of a sudden, it froze for no apparent reason. I rebooted [by pressing reset on case as keyboard wouldn't respond] and booted into XP and ran chkdsk on the Vista partition. Sure enough, it found two errors but in the index area. Here's the output of DOS window:
Code: C:>chkdsk /r d:
The type of the file system is NTFS.
Volume label is NEW_C.
CHKDSK is verifying files (stage 1 of 5)...
File verification completed.
CHKDSK is verifying indexes (stage 2 of 5)...
Deleting index entry SBEServer.exe in index $I30 of file 1153.
Deleting index entry SonicMCEBurnEngineIcon.png in index $I30 of file 1153.

I run on Windows Vista Business x64 SP1. I was updating a while back, and an update failed with an error code. So I followed the error code in Windows Help and Support, and it asked me to delete all the updates in my update folder and then try updating again. I did that, and now update gives me the 80070424 code, which is access denied.
So, here are the solutions I tried: sfc /scannow (cmd prompt was in admin) It does find corrupt files, except it can't start Windows Repair Service to repair it. So I tried going into Services.msc to turn Windows Modules Installer to Manual. However, since I technically "never updated", that is not in Services..................

I've lost the sound on my laptop and I don't know how to get it back. I have an HP Compaq nx9430 with 2 Gigs of RAM. Everything was going great after a clean install of Vista when all of the sudden (I don't know what happened or updated) the sound stopped working. Now, the strange thing about the sound is that I can uninstall everything, get rid of the dlls and .sys files for the drivers. Do a clean install of the sound drivers from HP's website and I can press my mute button to get the icon in the systray to go to mute and back. There are even little "sound waves" coming from the speaker in the systray. However, when I open Mixer, I can see "Speakers" but in the "Applications" groupbox, Windows Sounds and none of my applications come up. Applications is empty - yes, totally missing Has anyone ever run across this before? If so, what did you do to fix it? I'm at my wits end as I can't listen to music on my laptop while I'm at a coffee shop coding anymore!!
