Bug Description

Selecting Windows shows a frozen fuzzy screen. Find attached a photo of it.

Bug found in ubuntu 15.10 and earlier. (Ubuntu derivatives included).

Sometimes the frozen fuzzy screen stays for a few seconds and then I get the windows login screen. (successful boot).
Sometimes the frozen fuzzy screen lasts forever. however I could here the windows welcome sound play on the speakers; which indicates that it successfully boots but the display has this frozen fuzzy screen.
Sometimes the frozen fuzzy screen lasts forever with no signs of Windows booting whatsoever.

This bug is more likely to occur when dual booting with win8, win8.1 or win10.

There is a work around that often times work:
1- Highlight the windows entry.
2- Press e to get into the edit mode.
3- Press ctrl-x
4- It boots normally.
