I had a perfectly functional Windows 7 x64 Pro installation on my Mac mini (2011) until recently. Now when I attempt to boot it I get nothing but a black screen indefinitely. I don't recall having done anything in Windows that may have caused this; in fact, it's been some time since I booted into it. So, I'm suspecting it must be something I did whilst booted into OS X.
I've tried booting into Safe Mode by tapping F8 after selecting Windows from the Startup Manager - no change.
I've tried selecting the Windows install from the Startup Disk preference pane, but it doesn't actually appear there, oddly enough.
I've tried booting from a Windows 7 x64 Pro DVD in order to perform a Startup Repair, but this also goes to a black screen indefinitely. The DVD also spins down very quickly, which suggests to me it's not attempting to load anything much (if at all) from the DVD. I've tested this Windows DVD on a different Mac and it boots fine.
My Mac mini uses the Intel HD 3000 integrated graphics, and I don't recall this being a problem when I initially installed Windows.
Here's the partition information for the disk with the Boot Camp partition on it:
Here's some additional info on that disk:
From what I can tell, this means my hybrid MBR is intact.
NB: The disk containing my Boot Camp doesn't have a bootable OS X install on it. That's actually safe, and perfectly functional, on a separate internal drive.
I asked for help on the Apple forums but didn't get anywhere. Hopefully someone here will know more?
