 MBR + rack
Author: kdi

Hello to everyone!

I have encountered the following problem:
1. There was a tuned system with a BIOS Award and one 120 Gb HDD and Windows Xp OS.
2. Another system HDD was put into the rack. This HDD contained 3 OSs: FReeBSD, DOS and XP. Booting was controlled by the FreeBSD multi-boot system. The rack HDD was immediately detected, the computer booted from the rack HDD and the MBR screenshot appeared. We tried to load the rack XP but it failed to do so. Reboot followed. The MBR loaded again and we started DOS. We succeedeed. We were working on the rack HDD and we managed to do everything we wanted (it was not system related). Therefore we do not know if DOS detected the other HDD. We switched the computer off.
3. We took the rack out and turned the computer on. Although the computer did not have the rack HDD, the screenshot that appeared was that of the rack one. When we tried to start Xp the logo appeared but after a few seconds the computer reseted.
4. Cause of the error: the partitional table of the original 120 GB HDD is overwritten and it contains the partitional table of the rack HDD.

Concerning the solution its indefferent how the partitional table was overwritten, however, I am really eager to find it out. In what cases could the FreeBSD multi-boot system cause such a disaster? How could I find the error and simulate it once again just to avoid such disasters in the future?
