Janusz asked about where to install the boot loader when running grml2hd
By default it is placed in the partition boot sectors rather than the master boot sectors at the beginning of the disk. I always use grub rather than lilo as a bootloader. I'm more familiar with it. Write down which partition you installed grml and grub to. Let's say it was /dev/sda3
Installing to the mbr should be fine but when it goes wrong you may lose access to XP also, as well as the newly installed grml. This usually means you made a mistake somewhere. It can be rescued using the cd. But make sure you have a copy of the original mbr on a floppy or pen drive.
Installing to the partition means you avoid that but you will probably find that the 1st reboot loads into XP instead of grml. This can be overcome in several ways a) by making a boot option in C:\boot.ini in XP (Does not work in Vista as it boots differently) b) by booting the CD then at the first (isolinux) prompt go grub enter enter c) by having already make a separate boot floppy or usb pen.
You should now have a list of options but go 'c' to give you a grub command line
grub>
In grub terms /dev/sda3 is (hd0,2) So now go
grub> configfile (hd0,2)/boot/grub/menu.lst enter
This should load the grub menu and you just hit enter again to make it boot. If you had installed to the mbr instead of the partition then you don't need to do this it will boot straight into grml.
