Can't use "touch /forcefsck". Root file system is mounted read-only due to disk problems. Cannot write to /. Cannot "mount -o remount,rw /" either. What now? :)

at grub boot screen, hit 'a', append 'init=/bin/sh', after booting into shell you should be able to do the fsck, or do the remount and touch /forcefsck also try single user mode (just append '1')
