Consider that you could have a disk problem or the last shutdown did not write the cached data to the disk for some reason, like a bad shutdown. I say fix grub 2 and then if it works, back up your data and consider it may be time for a new hard drive.
I ran fschk on /dev/sha5 (ext4 file system) and it reported no errors
memtest reports no errors
before I had tried to fix grub the first time (dual boot, I went into windows and ran disk check on NTFS partitions and they reported no errors)
I am sure if I can get into the suse install its ok, just can’t get there
I am using 64 bit system, AMD 1090T , 4gb ram, 500gb hard drive with 4 partiations, 1 windows, 1 ntfs backup of windows (acronis images) , 1 swap and 1 ext4
I have decided to try to re-install without formatting the ext4 partition and see if the files are still there, might be a mess but I will try to patch the changed files if it loads
I can’t say anyone has ever said they had to switch to ext3 in order to get openSUSE to boot grub, but what ever works is all we are ever looking for and happy to hear you did find a solution.
