IIRC, no.

That's a pity. IIRC, lilo used to save that under /boot.

If it were in place, I wouldn't have the problem -- it would have
protected the internal drive's MBR.

It's Windows XP with Sophos Safe Guard Easy. I added the Windows
partition to grub2. It seems to load the partition boot sector. After
that it should have asked the filesystem password. But it says that MBR
checksum is not correct and refuses to continue.

IIRC, it didn't boot from the USB drive, so I switched to the internal
drive.

I would be happy to know a way to restore the MBR (or, in general, boot
Windows) without having to reinstall it.
