This computer was running fine until I rebooted it on April 1st. Hmmm. Sounds like a virus, eh? My anti-virus software subscription is up to date and a system scan was run about 30 hours prior to the reboot.

When I move the drive to another XP box, all the files are still present. I've backed them all up to the other system and have been working with it.

My non-booting drive has 7tools BootManager on it. When the machine starts, it reads the boot manager from the hard drive, but only lists drive A: as being bootable. It used to list C:. Using the XP Repair console, I've verified that the files NTLDR and NTDETECT.COM are both on C:\. Using the fixboot command does not fix the problem. Using fixmbr tells me that the MBR is either damaged or non-standard, so it suggests not overwriting it.

Is there a way to overwrite the 7tools boot manager with the default Window boot manager? I don't know exactly what 7tools is looking for, but maybe it's corrupted.

I could just buy a new drive, install XP, then put the old drive in as D:, but I'd prefer to get the original disk booting again.

Any suggestions?

It could be a virus. Iím not one to quickly blame computer problems on viruses but
I have had a similar experience some time ago. NtLDR and NTdetect is the most
Common misunderstood targets for viruses. Not to say that these boot files canít be
Attacked by a virus they just rarely arenít. You may have a Virus in your System
Volume Information folder. No antivirus software in the world will locate a virus in the
System Volume Folder. Every time you remove a virus and reboot it will reinstall itself
From this folder.
You can reformat you HD and reinstall windows. If you do I would download NTFS4DOS and format your HD first. Then install windows. When Windows install
Formats your HD it doesnít replace the System Volume Information folder, It copies
files to it. Its worth a shot. Good luck

It's possible that the 7tools boot manager rewrote your boot sector using it's own format - and that would explain the results of fixmbr.

I'd suggest a bit of research on the 7tools software - and then use the fixmbr command to repair the MBR. This will remove references to other OS's that you may have installed, but should be a small price to pay for getting your XP back.
