Boot Camp iMac mid 2010 Ultimate 7 x64 BSOD (?)

[hazerjohn]

Hi everyone

I have an iMac (mid 2010) and am desperately trying to install Windows 7 Ultimate x64.

The installation went perfectly fine until the final reboot. Upon that, it is suppose to boot in Windows.

However, a black screen with a blinking underscore (_) shows up immediately when I boot the HD, nothing happens. I've been trying to find a solution for hours, any help or advice would be greatly appreciated!

Thank you for your time

Okay, stupid question maybe but do iMacs mid-2010 tolerate Windows 7 x64?

I don't see it on the list: http://support.apple.com/kb/ht1846

After countless hours of search, I found the solution on this thread.

Here are the steps:

Repair startup issues
1. Put the Windows 7 installation disc in the disc drive, and then start your computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then 4. Click Next.
5. Click Repair your computer.
6. Click the operating system that you want to repair, and then click Next.
7.In the System Recovery Options dialog box, click Command Prompt.

Type (these commands are safe - more information)
Code: Bootrec.exe /FixMbr
Code: Bootrec.exe /FixBoot
Code: Bootrec.exe /RebuildBcd
Press ENTER after each command.
Restart your computer.

Not sure if you have fixed it yet, but just thought I'd point out that I have a new iMac 27" i7 w/ ATI 5750 and I have Windows 7 x64 boot camp installed and working fine.

I never had any issues installing, however, I did install the drivers on the OS X DVD, and upon reboot I got a BSOD and I had to reinstall Windows. I opted not to install the drivers this time. This has it's own issues though, cos the Mic doesn't work properly and USB 2.0 and FireWire 800 are ultra slow... so I need the drivers for those, but now sure what manufacturer the are to get the correct drivers.
