Hi, I tried to upgrade to 11.1 yesterday but I ended up with an unusable system. At startup, after choosing OpenSUSE 11.1 in the GRUB boot menu I get the following error message: ------------------------------- VFS: Cannot open root device disk/by-id/ata-MAXTOR_STM3320620AS_6QF1LW22-part 4 or unknown-block(0,0) Please append a correct "root=" boot option; here are the available partitions: kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) ------------------------------- I started with a perfectly working dual-boot config Vista/OpenSUSE 11.0. I ran the install wizard from the LiveCD and selected "Edit Partition Setup..." to confirm the existing config of the drive: ------------------------------- Device Boot Start End Blocks Id System /dev/sda1 1 25527 205045596 7 HPFS/NTFS /dev/sda2 * 25528 25539 96390 83 Linux /dev/sda3 25540 25601 498015 82 Linux swap / Solaris /dev/sda4 25602 38913 106928640 83 Linux ------------------------------- File systems / mount points: ------------------------------- sda1 NTFS [Vista] sda2 EXT2 /boot sda3 SWAP sda4 EXT3 / ------------------------------- The install process worked without apparent problem but when I rebooted I got the error message above. My menu.lst looks like this: ------------------------------- # Modified by YaST2.
