Hi,

I installed grub by connecting the hdd to my workstation. This did not
change anything.
Also I changed /etc/fstab . Now I have 0 0 for every partition. The pc
boots fine now. I can use it but ... There is no /dev/hd* . Running
mount /boot I get the answer /dev/hda1 does not exist. Also there is no
/dev/sd*

Any ideas?
