[Bug 1259701] [NEW] 14.04 installer does not detect Windows 8.1

[Smot]

Public bug reported:

Just tried using 14.04 daily build (10th Dec) on HP Pavilion Touchsmart
11. (Aside note: This is the first build since 12.04 that actually runs
on this PC - previous releases lock up with a black screen or terminal
login prompt that doesn't run anything).

The installer starts, but does not detect that Windows 8.1 is already
installed on the PC.

I was hoping to install 14.04 alongside Windows - I'll scrub Windows
when the full LTS is released, but until then I need to keep it.

I did not proceed with the install as I wasn't confident that I'd mess
up the partitioning and end up without an OS.
