It sounds like you are telling the kernel the wrong root partition in grub (or not specifying any root partition). For example: menuentry "BLFS Dev (LFS-SVN-20121013), Linux 3.6.2" { linux /vmlinuz-3.6.2-lfs-20121013 root=/dev/sda16 ro } GRUB is finding the kernel, but the kernel is not finding the right root partition. Try: menuentry "BLFS-7.2" { set root=(hd0,3) linux /boot/vmlinuz-3.3-rc1-lfs-7.0 root=/dev/sda3 ro } -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
