OK, thanks for the info. With the boot disk I am now able to get into linux and to mount my windows drive. Still, when I boot-up without the diskette, I see "LIL-" and the system hangs. So I don't get into X. I tried to copy the files on my windows disk to the linux disk, but it gives an error. I am really new into linux, so maybe i give the wrong command for copying the entire tree of files.
I also checked the /etc/lilo.conf, and that one looks ok. To me, it looks like there is something wrong with booting-up. The computer tries to start the lilo prog, but fails to run it. Any sugestions!!!!!
