I had a dual-boot system of Ubuntu 14.04 and Linux mint 18. From grub I used to be able to choose Ubuntu, or Linux mint 18 on sda2. Recently, I deleted the Ubuntu partition, which was on sda3, but now whenever I boot my computer, grub2 doesn't know what to do and I just get the grub2 command line. I'm not sure what course of action I need to take to boot into Linux Mint, which has all my files.

If any more information about something is needed, I can probably provide it.

Thanks

    What is the output of ls and set from the grub rescue? – GAD3R Nov 3 '16 at 16:31

You can boot your system from grub2 rescue Then reinstall it :

First run the command set, it will give some information about the tow first command ( boot + root) to run from the grub rescue :

set prefix=(hd0,1)/boot/grub
set root=(hd0,3)
insmod normal
normal

If you cannot boot from the grub rescue , boot from a linux live CD/USB and reinstall grub on your hdd following this tuto

  • Thank you! I was aware of the set command, but not of insmod. I'm able to boot by set prefix=(hd0,2)/boot/grub and then insmod normal and normal – Osmiridium Nov 3 '16 at 17:52
  • Use this tuto howtoubuntu.org/… to restore grub , if you have a separate /boot partition mount it also . – GAD3R Nov 3 '16 at 17:54
