[Tfug] newbie questions

[Jeremy D. Rogers]

Also, if you want to avoid changing drive order, you can use the boot
loader to switch what windows thinks is the "master" and "slave" drives via
map-drive in lilo for example:

other=/dev/hdb1
label=WindowsNT
map-drive = 0x80
to = 0x81
map-drive = 0x81
to = 0x80 

man lilo and search for map-drive for more. Grub is slightly different:

title win
map (hd1) (hd0)
map (hd0) (hd1)
rootnoverify (hd1,0)
chainloader +1 

I've done this before in LILO with windows on the slave drive and no
problem, but I haven't tried swapping drives ingrub. Here is the thread
where I found the grub info:
