And the instructions from a message in private mail: OK, I tested the file I sent you and it works :-) I did dd if=both of=/dev/fd0 bs=512 and then I rbooted with that floppy, and I dropped into the grub shell. I hope it works for you too. in grub you need the folowing commands: root (hdb0,3) -- tell grub you are looking at disk 1, partition 4 kernel /boot/youkernel boot=/dev/hda4 ro -- tells grub your kernel boot -- tells grub to go ahead (I managed to load it, but didn't feel like learning something new after I managed to load my system from the slackware floppy, see below). Actuaklly in the end I used a slackware boot image, and used 'mount root=/dev/hda2' This was basically what I needed: a floppy image that allows me to load my existing partitions. As for the CD: I'm not sure if it is a hardware problem or not (it was set to load from the CD, and it worked in the past. I tried various CDs, at least one of which I tried quite recently). My guess is that this is a hardware problem, maybe with the IDE controller connections. However if I touch it there is a reasonable risk that it will escalate into a situation where all the IDE disks are not accessible (in other words: I hate hardware, and don't like touching it when I don't have to).
