GRUB rescue

n0man0r · 02-07-2017, 11:53 PM

Hello,

I have been running linux mint on my old laptop for the last few months. I booted it up today, and I have the message:

error: unknown filesystem.
Entering rescue mode...
grub rescue>_

I've tried this:

http://askubuntu.com/questions/11959...own-filesystem

But it doesn't seem to be working. I was wondering if anyone had any ideas.

n0man0r,

Welcome to LQ.

On another computer, download and burn to CD/DVD one or both of these tools and read the instructions carefully.

Boot Repair:

Welcome n0man0r! Ditto bb2: Boot-Repair worked for me: just click its 'post' (or 'repair').
I'm following this to learn. @n0man0r, did you know which partition was your / (root fs)?
The examples in the link you followed use sda6; your's may be sda1 [?].

Best wishes. I'm glad to see LQ responded so fast (and a great response!)

p.s. IF you want doc/tech-tutorials on the details ('theory') of "grub rescue>" (vs. "grub>")
some of the LQ "Similar Threads" at bottom of this page, lead to things like:

rescatux has a very nice grub rescue feature that has indeed rescued me many times without fail.
don't be put off by the "beta" version, it's really very stable.

Grub or any bootloader doesn't usually just 'decide' to stop working. Your post indicates you have Linux Mint installed and the link you reference indicates a multi-boot with two windows versions. Is that what you have? Also in the link, the OP indicates a modification of the system by creating another ntfs partition. Without the output of the bootinfoscript or boot repair this will just be guessing.
