I run a dual boot w/ Windows 7. Recently, I installed Windows 7 Service Pack 1 which, surprise surprise, screwed up Grub and left Windows the default OS w/ no option to boot into Ubuntu. This is usually a pretty easy fix (boot-repair), but the problem is I can't get a LiveCD that boots.

When I boot from a LiveCD usb, the screen flicks to TTY1, then to a black screen. The screen stays black unless I press ctrl + alt + F1 to get back to TTY1, where I'm then asked for a username and password. I've tried ubuntu with a blank password and this does not work.

I'm using this image. I've tried with a fresh USB multiple times. Anyone have any ideas?

  • To start solving the issue you probably need to post `/var/log/Xorg.0.log`… But, as the actual problem you need to solve is to just restore grub, [you can do it from the tty perfectly fine](http://askubuntu.com/a/88432/266507), there's no need at configuring Internet, and alike. If you really need Live CD/USB, you could also try to boot from Fedora with Gnome, because… err… I struggle to say specifically, just a number of trivia tends to be more stable. – Hi-Angel Sep 06 '16 at 19:33
  • Ah, yeah, blank password didn't work. Well, in this case give a try to another LiveCD. At the very least, where password is working – Hi-Angel Sep 06 '16 at 19:40

Try using EasyUEFI in Windows to adjust the boot order -- move the ubuntu item to the top of the boot list. This should fix the problem; however, be aware that there are buggy EFIs that may forget boot entries or have problems with re-ordering them. There's also a slim chance that Windows has deleted the Ubuntu entry, in which case it will have to be re-created.
