I'm still strugling with this thing. So far I managed to get kde of the old installation working with reinstallation of nvidia drivers. However problem with fresh installation still remains, but is somewhat different. When I got new disk I decided to make partitions with gparted, so I thought that suse may not have liked that. So I deleted all created partitions and created them again with suse during installation. This time the installation completed successfully with kde running. Momentary I was pleased everything went ok, but after I rebooted pc, I got stuck at the same point I was with previous installation attempt, that is the new disk is not bootable. Therefore I susspect grub did not manage to write it self to mbr. Grrr
....any ideas why there is not mbr on my new disk? Thanks again.
