Hi Kristof,

Here are a couple of ideas that you might want to try before completely
destroying your system:

1) Try to boot to a lower runlevel, most likely single user mode, and
hopefully you can gain enough access to your system to fix with fsck.
To get to single user mode from lilo you can simply type "linux single"
without the quotes at the boot prompt. From grub, this process is a
little different. All you need to do is select the kernel you want to
boot, press "e" for edit, then add the word "single" to the end of the
boot command. After this, go back to the grub screen ("Enter") and boot
this modified kernel line ("b").

2) Boot your system using an operating system that sits entirely on a cd
or a usb device. If you can boot to this operating system and mount the
bad drives from this OS, then you quite possibly can fix most problems
of your broken disk. Personally, I prefer knoppix (www.knoppix.org) for
this kind of work.

Best of luck,
