openSUSE 12.2 grub2 problem Feb 10th 2013, 20:57 Yesterdays kernel update from 3.4.11 to 3.4.28 left me unable to boot. - The PC was stuck at the boot screen. It was unable to find the 3.4.11 kernel. I did get it to boot by booting the install DVD, used the Rescue System, chroot, and then: Code: # grub2-mkconfig -o /boot/grub2/grub.cfg I did try to use yast when I was in the chroot but when I went into >system >>bootloader I received this: Code: Error:  because of the partitioning the bootloader cannot be installed properly The PC has only 1 operating system openSUSE 12.2 64 bit. - I did a new installation from the install DVD. - The PC had openSUSE 12.1 on it but I did not perform an upgrade. I do remember having issues right after I installed the system with getting the PC to boot, but I can't find my notes with how I "fixed it" then. The disk layout is: Code: baird-suse:~ # fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c7d83   Device Boot      Start        End      Blocks  Id  System /dev/sda1  *        2048    37752831    18875392  83  Linux /dev/sda2        37752832    46139391    4193280  82  Linux swap / Solaris /dev/sda3        46139392  312580095  133220352  83  Linux Disk /dev/sdb: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000bef49   Device Boot      Start        End      Blocks  Id  System /dev/sdb1  *        2048  488396799  244197376  83  Linux Code: baird-suse:~ # cat /etc/fstab /dev/disk/by-id/ata-WDC_WD1600AAJS-00L7A0_WD-WCAV26464221-part2 swap                swap      defaults              0 0 /dev/disk/by-id/ata-WDC_WD1600AAJS-00L7A0_WD-WCAV26464221-part1 /                    ext4      acl,user_xattr        1 1 /dev/disk/by-id/ata-WDC_WD1600AAJS-00L7A0_WD-WCAV26464221-part3 /home                ext4      acl,user_xattr        1 2 proc                /proc                proc      defaults              0 0 sysfs                /sys                sysfs      noauto                0 0 debugfs              /sys/kernel/debug    debugfs    noauto                0 0 usbfs                /proc/bus/usb        usbfs      noauto                0 0 devpts              /dev/pts            devpts    mode=0620,gid=5      0 0 /dev/disk/by-id/ata-WDC_WD2500AAJS-55M0A0_WD-WCAV2W720129-part1 /mnt/share          ext4      acl,user_xattr        1 2 I did look through this forum thread https://forums.opensuse.org/english/...grub2-efi.html . This is similar to my problem but this is a desktop PC without efi.
