2011 iMac won't install Windows 7 in Boot Camp
I'm attempting to install Windows 7 x64 on my 2011 (Thunderbolt) iMac via a burned, bootable DVD which was previously used to install Windows 7 x64 on my friend's MacBook Pro. Apparently, the disc works. After partitioning one of my internal drives in Boot Camp, downloading the drivers and stuff Apple provided, putting that stuff on a FAT-formated flash drive, then attempting to install Windows, the install fails. Well, it doesn't really fail. Before I'm even given the option of installing, right after clicking the "start setup" button in the Windows Installer, I get an error saying "No device drivers were found. Make sure that the installation media contains the correct drivers, and then click ok." I go to scan and browse the flash drive for the drivers which Apple provided, and I get the same message over and over again regardless of what I click. I ran Software Update before doing any of this, and I have also attempted to install the x32 version of Windows 7 as well, as to no avail. I would try burning the Apple-provided drivers and stuff to a CD or DVD, but obviously there is no way to insert such a disc into the drive since the Windows disc is already in.
These are my computer's specs, if they matter:
2011 Thunderbolt iMac
2TB storage, partitioning 100GB for Windows
3.4GHz i7 quad-core
16GB RAM
Radeon 6970 with 2GB VRAM
...attempting to install Windows 7 Home Premium (I think) x64 (or x32 if I have to)
iMac, Mac OS X (10.6.7)
