When I first read your message, I thought you must be confused. There
is only 1 MBR on a PC. That's why it is the MASTER boot record.
Since you have changed your BIOS to look for the MBR in a different
location (/dev/hdb instead of /dev/hda) that might solve that issue.
I haven't tried this yet -- I need to get some Debian CDs to reinstall
first -- but according to GRUB's documentation (and assuming BIOS
compatibility) you should be able to make /dev/hda the linux disk and
/dev/hdb the NT disk (physically switching the disks on the bus).
THen use grub's swap functionality to make NT *think* it is on the
primary master disk. (But switch the BIOS back to using /dev/hda as
the MBR)
Another alternative you have is to always boot off the floppy. Not
quite ideal, but it isn't so bad either.
BTW, GRUB is the coolest thing I have seen yet. I was able to use it
to dual boot a Win2k/RH6.2 system I had to install at work the other
week with no trouble. The linux kernel is above the 1024 cylinder
too. I tried LILO on a floppy first, but after a fair amount of
difficulty, it still couldn't boot windows. Being able to configure
it /before/ an OS is running is very crucial for inexperienced users.
It's shell is very cool
too.
