I had a system with a M810-xp motherboard, i changed this for an intel based 925 motherboard, and my OS displays an unmountable_boot_device, is there anything i can do to have my Win Xp running again? I mounted another disk with Win Me, but i don?t know what to do.
Thanks

Fdisk, activate partition ?
Else, boot on XP cd, and start install from scratch.

Your essential problem is that the IDE controller on your new motherboard is different than the IDE controller on your old motherboard and thus uses different drivers (which don't exist on your hard drive. Therefore, your new motherboard has no wayof accessing the hard drive.

Solution: If your old motherboard still works, reinstall it and implement the solution found in Microsoft KnowledgeBase article 314082 (You Receive a Stop 0x0000007B Error After You Move the Windows XP System Disk toAnother Computer). Your new motherboard essentially makes your computer a different one from the one XP was installed on.

If this doesn't work, your options (in order) are to attempt a repair installation (as suggested in Answer 2, or wipe the disk and install XP from scratch.

Hope this helps.

Reboot from the CD and start the install. When it asks to repair from the console continue as if you were installing a new OS. when the installer looks for a current install of windows and finds one, choose repair. It will reinstall drivers and somesystem files. You will need to run Windows update if you so choose.
