Legacy GRUB had many virtues, but it became old and

its developers did yearn for more functionality, and thus did GRUB 2 come into the world. GRUB 2 is a major rewrite with several significant differences. It boots removable media, and can https://www.quora.com/How-do-I-fix-a-grub-rescue-unknown-file-system-error be configured with an option to enter your system BIOS. It's more complicated to configure with all kinds of scripts to wade through, and instead of having a nice fairly simple /boot/grub/menu.lst file with all configurations in one place, the default is /boot/grub/grub.cfg. Which you don't edit directly, oh no, for this is not for mere humans to touch, but only other scripts. We lowly humans may edit /etc/default/grub, https://www.linux.com/learn/how-rescue-non-booting-grub-2-linux which controls mainly the appearance of the GRUB menu. We may also edit the scripts in /etc/grub.d/. These are the scripts that boot your operating systems, control external applications such as memtest and os_prober, and theming./boot/grub/grub.cfg is built from /etc/default/grub and /etc/grub.d/* when you run the update-grub command, which you must run every time you make changes. The good news is that the update-grub script is reliable for finding kernels, boot files, and adding all operating systems to your GRUB boot menu, so you don't have to do it manually. We're going to learn how to fix two of the more common failures. When you boot up your system and it stops at the grub> prompt, that is the full GRUB 2 command shell. That means GRUB 2 started normally and loaded the normal.mod module (and other modules which are located in /boot/grub/[arch]/), but it didn't find your grub.cfg file. If you see grub rescue> that means it couldn't find normal.mod, so it probably couldn't find any of your boot files. How does this happen? The kernel might have changed drive assignments or you moved your hard drives, you changed some partitions, or installed a new operating system and moved things around. In these scenarios your boot files are still there, but GRUB can't

The system has three drives. Multiboot is configured with Windows XP, Windows 7, and Ubuntu - all on the first drive. I had a lot of unpartitioned space left on the drive and error unknown filesystem was reserving it for adding other OSes and for storing files there in the future. One day I went ahead and downloaded Partition Wizard and created a logical NTFS partition from within Windows 7, still some unpartitioned space left over. Everything worked fine, until I rebooted the computer a few days later. Now I'm getting: error: unknown filesystem. grub rescue> First of all I was surprised not to find any kind of help command, by trying: help, ?, man, --help, -h, bash, cmd, etc. Now I'm stuck with non-bootable system. I have started researching the issue and finding that people usually recommend to boot to a Live CD and fix the issue from there. Is there a way to fix this issue from within grub rescue without the need for Live CD? UPDATE By following the steps from persist commands typed to grub rescue, I was able to boot to initramfs prompt. But not anywhere further than that. So far from reading the manual on grub rescue, I was able to see my drives and partitions using ls command. For the first hard drive I see the following: (hd0) (hd0,msdos6) (hd0,msdos5) (hd0,msdos2) (hd0,msd

However, after I rebooted the system, instead of being greeted by a friendly GRUB screen, I get the following screen instead: L99 99 99 99 99 99 (ETC) It's the strangest error I've seen in a while... I tried runnign the repair utility on the suse dvd, and it claimed to successfully reinstall GRUB, but I still get the same error. Any ideas?

Perhaps the previous boot loader was LILO? Make sure GRUB was installed in MBR, possibly by reinstalling it with grub-install. But of course, first you need to access your system. Use your SuSE DVD, boot into rescue mode, mount the root partition somewhere, chroot to somewhere, run grub-install to the hard disk device *without* a partition number. In my case that would be Code: grub-install /dev/sda Then reboot and see what happens. Don't know how to do the mount/chroot maneuver? Let us know and we can go into further detail.
