grub rescue> question
I would appreciate any suggestion as to how to proceed here. I have gone as far as I know how without screwing up. Thanks in advance!
My linux Mint 17 Cinnamon has run into a grub rescue> situation after trying to play a video online. The ls command produces the following: (hd0), (hd0,msdos3), (hd0,msdos2), (hd0,msdos1), (hd1), (hd1,msdos2) and (hd1,msdos1) I tested all 7 possibilities with the commands recommended online set boot= (hdX,Y)/boot/grub set prefix= (hdX,Y)/boot/grub insmod normal normal 6 of them resulted in "error: unknown filesystem" BUT the (hd0,msdos3) showed "error: file boot/grub/i386-pc/normal.mod not found". After booting with the original Linux Mint 17 "Qiana" - Cinnamon (64-bit) installation CD, Gparted shows this: /dev/sda1 - unknown - boot (about 28Gb) /dev/sda2 - linux-swap (about 9.5 Gb) /dev/sda3 - ext4 (about 112 Gb) and a message 'unable to detect file system" and listing possible reasons. Personal data is all there. Looking at this drive with Gparted on my other Mint 17 system, I get similar result, only the the partitions are called /dev/sdb1 through 3. QUESTION: Which of the drive/partition names do I need to use in the commands set boot= (hdX,Y)/boot/grub and set prefix= (hdX,Y)/boot/grub etc....? What else should I do?

I have gone as far as I know how without screwing up. Thanks in advance! My linux Mint 17 Cinnamon has run into a grub rescue> situation after trying to play a video online. The ls command produces the following: (hd0), (hd0,msdos3), (hd0,msdos2), (hd0,msdos1), (hd1), (hd1,msdos2) and (hd1,msdos1) I tested all 7 possibilities with the commands recommended online set boot= (hdX,Y)/boot/grub set prefix= (hdX,Y)/boot/grub insmod normal normal 6 of them resulted in "error: unknown filesystem" BUT the (hd0,msdos3) showed "error: file boot/grub/i386-pc/normal.mod not found". After booting with the original Linux Mint 17 "Qiana" - Cinnamon (64-bit) installation CD, Gparted shows this: /dev/sda1 - unknown - boot (about 28Gb) /dev/sda2 - linux-swap (about 9.5 Gb) /dev/sda3 - ext4 (about 112 Gb) and a message 'unable to detect file system" and listing possible reasons. Personal data is all there. Looking at this drive with Gparted on my other Mint 17 system, I get similar result, only the the partitions are called /dev/sdb1 through 3. QUESTION: Which of the drive/partition names do I need to use in the commands set boot= (hdX,Y)/boot/grub and set prefix= (hdX,Y)/boot/grub etc....? What else should I do? Bootinfoscript Results.txt: is included in my second post "grub rescue> question part 2" |
Hi there.
Have you tried booting off a boot-repair-disk CD/DVD/USB (https://sourceforge.net/projects/boot-repair-cd/)? That successfully repairs the mbr/gpt/grub setup in many cases. |

Hydrurga -
Even before trying the boot-repair-disk, I checked the filesystem of my /dev/sda1 (boot partition) with fsck. It offered to do some changes there and I allowed it to do so. It is fixed and bootin - back to normal Thank you for your trouble, I do appreciate the kind help. Take care. |

It would be a good idea for you to consider making yourself a boot-repair-disk CD/DVD/USB anyway and keeping it around in case you need it some day. It has certainly proved very useful for me (I keep it along with all my other tools on a YUMI multi-boot USB stick). |
