I had an Ubuntu 14.04 and Windows 8.1 dual boot system with Grub2. After my recent upgrade to free Windows 10. GRUB is broken, it gave me the
grub rescue> prompt.
Reading on internet I figured I had to change prefix and root for GRUB to work correctly, and it did, but it reverted back every time it booted.
I am not a techie so to fix things instead of meddling with changing
/etc/grub.d etc., I used a boot repair USB key. It changed something and now I get
error symbol 'grub_term_highlight_color' not found
and I also can't find
normal.mod. The link is pasted that was generated by the grub-repair USB key. Help is much appreciated.
