So, I finally got the second install running, too... Don't know exactly where the error came from, but this is what I did: According to a PM from Carl I edited the fstab's of both the existing system and the new "fallback" system and removed in each all partitions that belong to the other. So now every system has a fstab mentioning only it's own partition(s). Then I did a complete new install of the "fallback" system on /dev/hda1. Again according to Carl's PM I did not install GRUB again (it is already installed in the MBR from the running system), I just said "install GRUB to floppy disk", but haven't used that floppy later. Just to see if it works I rebooted after the install finished. As I already had edited menu.lst before I could easily boot the new system from there. I have been so far before, too... Then I splitted up the YOU updates, to see where the failure could have arised. After each "part" downloaded and installed by YOU I re-booted to see if it still works. These are the parts: 1) unchecked everything but the new kernel 2) unchecked everything but GRUB-update 3) unchecked everything but Yast2 liby2util, perl-bootloader, yast2-booloader, yas2-users, yast2-packagemanager, insserv 4) unchecked everything but xorg-x11-server, x11-tools, xorg-x11. xorg-x11-libs, xorg-x11-server 5) all the rest So, I guess, I did a lot of unnecessary re-booting, but at least the new system now works perfectly, too... I have no idea why it didn't work last time, could be: - kernel update should be done separately, and/or - two GRUB installs (one in MBR, one in boot sector of /dev/hda1) don't work together, or - fstab containing mountpoints of other system is not liked by YOU regards Daniel -- Daniel Bauer photographer Basel Switzerland professional photography: http://www.daniel-bauer.com special interest site: http://www.bauer-nudes.com
