I installed Ubuntu 14.04.1 from a DVD I burned. Ubuntu runs perfectly, but when I select Windows 7 from GRUB, the screen goes blank (with some coloured lines at the very top of the screen). From here, the only way to get back to GRUB to force shut-down the machine from the power button.

I have updated grub2.

I have also tried boot repair, but all it did was create two Windows options from GRUB menu:

  • Windows 7 (loader) (on /dev/sda1)
  • Windows 7 (loader) (on /dev/sda2)

Both of them have the same result as earlier. Blank screen with some colourful pixels at the top of my monitor (top 2 or 3 pixels). Here's my boot repair pastebin.

P.S. This is not a duplicate of Can't boot Windows 7 after installing Ubuntu as I am able to select Windows from the grub menu but it crashes afterwards.

  • why don't you use startup repair with a windows cd or any windows media? – Chinmaya B Jul 26 '14 at 6:58
  • @bain please remove the duplicate flag, I have specified as to why it is a separate problem and have discovered a solution and would like to post it as the answer. – Chwana Jul 31 '14 at 11:44
