BOOTCAMP HELP! Posted: Mar 6, 2010 2:54 AM Reply Email Hello all - need some help please if possible. I've tried to bootcamp my Imac with windows. I installed my windows disc but now get the following error message on a Black screen Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: it goes on and on... Anyway - the mouse and keyboard no longer work - and when i restart the mac manually - (power button) when it goes back on - it goes back to black screen with "Windows is loading files..." then back to the intial screen above - any help would be most appreacited. (Also i'm unable to eject the disc?) Many thanks Parkie.
