GRUB2 disappeared from boot somehow..

[Zekester2097]

How did this happen?? Somehow yesterday, I booted up my laptop, saw the usual EFI "Toshiba. Leading Innovation" screen, then instead of loading into GRUB2, It showed the Windows loading wheel... I can't figure out how to get it back. I cannot use my live CD (actually its an 8GB flash drive), since its acting up for some reason, for example, it freezes constantly, and when i open the applications box thing, it doesn't show anything... I somehow got it (by "it", I mean my PC) to load into Ubuntu from the Boot Options thing in WIndows 10, but I forgot how I managed to do it . How can I fix GRUB2? since I can't access Ubuntu 14.04 without it....

Add an entry to the Windows bootloader for your Ubuntu partition. Then you should be able to boot into Ubuntu and either keep the Windows bootloader, or repair GRUB from within Ubuntu if you want to go back to using GRUB.

Looks like that's by design since you're booting in EFI mode. You'll need to get into Ubuntu somehow again and reinstall Grub from there, it sounds like.

as a last resort, couldn't I reinstall Ubuntu? would that reinstall GRUB??

You shouldn't need to totally reinstall Ubuntu...if you can even get into an Ubuntu LiveCD / installer, you can reinstall GRUB.
