Repair Windows XP installation (0x000000ED and 0x0000007B)


I have an old Toshiba Tecra A3x portatil computer with Windows XP. I had to switch it off by unplugging the power cord after the SO hanged. Since then the computer doesn't start. It shows the awful blue screen of death instead with the code 0x000000ED: BSOD 0x000000ED

I have tried to repair the installation using a Windows XP SP3 ISO image but I keep getting another error: 0x0000007B BSOD 0x0000007B

The problem seems to be that Windows can not find the hard disk controller. I have read that changing the HDD mode in the BIOS does fix the problem, but my computer does not have such option: BIOS Page 1 BIOS Page 2

I can mount the filesystem in Linux (Knoppix) and it seems to be ok. I have also tried to fix it with ntfsfix but nothing has worked.

These are some other things I have tried without success:

  • Boot in safe mode
  • Boot with the last working configuration

Can I pick your brain about how to fix this error?

If you believe the drive to be OK (may not be - may have errors) and further attempt to repair did not work, then your option with XP is to re-install XP.

Boot again with Linux as you did, recover the data to a USB connected HDD / SSD.

Once you have your needed data, re-install XP and recover the data you need.

You still may possibly find a disk drive error when you attempt to reinstall which means replacing the disk.

Good luck.
