Just do "sudo /bin/bash" to start a root-privilege shell. If you really
need direct login as root, then run "sudo passwd root" to set a
password. *buntu variants are really big on discouraging direct use of
the root-user login, and making people get access to root privilege

When you say "grub", here, what specific thing are you asking about?
There's a program called /usr/sbin/grub, which writes bootable
information to locations specified in /boot/grub/menu.lst .
SystemRescueCD has that program in a useful place on its live-CD
system; you don't need to worry about _its_ location. You just use it.
You'll want to grab your regular menu.lst out of /mnt/mydir/boot/grub
and copy it to /boot/grub (on the live system). Review it to make sure
it's correct, then do the usual with grub-install, and so on.

That is correct.
> When grub attempts to start Debian, it halts on unknown partition type
According to information in /sbin/fdisk, partition type 7 is
"HPFS/NTFS", so that's presumably your MS-Windows main (only?)
Again, correct the references in menu.lst, then re-run grub-install.
