Stop error 0x7b, tried chkdsk /r - didn't help, no restore points. It's XP pro on DELL desktop.
I need to save all applications installed on client's computer. I'm wondering if after repair install, I will be able to run all those apps (financial software, that cannot be reinstalled).  Or maybe there is another way to fix BSOD.
Thank you.

Any app that stored it's configuration info in the registry will no longer run after a repair install and will have to be re-installed. A repair install will ONLY preserve the data files on the system.

Boot into the recovery console and try these two commands:

fixboot
fixmbr

Answer Yes to each when prompted.

Was something recently changed to cause this?  Copied drive, new hardware, new driver?  If not this could potentially be due to a virus.  I would suggest a virus scan of the disk, but if the drive is physically failing the more you do with it the worse it will get.  If file recovery is a necessity, and disk failure is a possibility be very limited in what you do and consider a professional data recovery service.

drive is physically in good condition. I did fixboot and fixmbr also - didn't help. Client told me that before crash he removed some programs and temp files. I will try to scan it with malwarebytes. Do you think if it will remove some malware - windows will boot?

if it is a virus that can be repaired it is a possibility.  so you will need a bootable virus scan that can repair rather than just delete.  you may be able to install avast from safe mode and schedule a boot time scan from there.  Sounds more likely that someone just grabbed a bunch of files and hit delete, and something had to do with a driver.  Can you boot into safe mode to find a possible driver problem and repair it?

no, can't boot into safe mode, doing scan with malwarebytes on HDD attached to another PC - it's clean. I found a restore point (Oct 2008) on registry restore wizard (UBCD4Win). will it work?

Client says, it's better than loose all of them. I hope restore would work, if not.... I have no idea what to do, except reformat. (all data backed up)

0x7b is an "Innaccessible Boot Device", which can be a multitude of things.....

I would ghost the drive prior to trying any disk checks etc.... That way you have a scratch drive to run tests on, HDD diags etc....

Once you have a ghost, I would try running a chkdsk from another machine while it is slaved....

chkdsk /f /r

And actually, I havent had a need to do many repairs, and personally I dont like them. I would rather reformat... But in your case, of a critical need for apps to work, I would try the Repair Install.... I am more than positive it doesnt  hurt MOST apps, but Updates will need to be reapplied. I have seen apps like Office/AV not funtion right, but those were easy to remedy.....
