Ubuntu 16.04 upgrade problem

[account_disabled]

Just attempted to install Ubuntu 16.04 beta over 14.04. I have used 14.04 for a couple of years with no issues whatsoever. However during the installation (by download) the new installation froze 2/3 of the way through.



I am using a two hard disc sustem 1x 128g disc running XP and a second x250g running Ubuntu 14.04. Storage no issue.



Hi,

Now, when I start up and reaching the options page, booting Ubuntu results in a blank screen. No mouse or Keyboard operational.

Reverting to Advanced options I can enter the generic recovery mode

All options tried, Resume, Clean, Failsafe X, FSCK, grub, network, root, System Summary.

If I then go to resume Ubuntu The screen displays white square blocks and lines in between. No mouse or keyboard operational.

Summary, I think I may have damaged the initial 14.04 programme with the part installation of 16.04.

With no keyboard and mouse I am struggling to find a way forward.

I now also have iso discs for 14.04 and 16.04

Please help.

Thanks!

I didn't find the right solution from the Internet.
