Automatic Repair couldn't repair your PC.

Press advanced options to try other options to repair your pc, or shut down to turn off your pc.

I can't even select either of these options as my keyboard and mouse won't work...I am running os lion too which works perfectly...I haven't created a bootable copy of windows 8 either...please help me solve this problem...

    Windows 8 is not supported in Bootcamp You can expect to get errors and non useable hardware.

    Make sure you use the win7 amd driver not the win8 one

    There are no Win8 drivers for Boot Camp yet.

    Well I'm planning to delete that partition now...but is there any way I can create a bootable flash drive for windows 8? I have the licence key...but not the iso file...I don't know how I could download the ISO file again...

    no official apple drivers but apple dont make video cards AMD does and when one updates a win7 install to win8 windows will find a newer driver for the amd video card in my iMac and if I install that all **** breaks loose

     

    as in it crash with fatal bluescreen of death and many times at startup but if it makes it passed

    that critical point it works fine

     

    same deal with the apple soundcard it's a cirruslogic and cirruslogic have win8 drivers ready

    win 8 worked fine for a number of weeks on my 2009 mac pro, i got four drives, os x, opensus 12, win 7 and win 8, as I said everythiing worked out of the box, no isues with drivers at all,  until I got some update for win7, it trashed win 8, win 8's auto repair trashed win 7, yada yada, finally got win 7 back again, but still 0xc0000021a error on win 8, look like a reset for me :-(.    (Win 8 was working fine two days ago - prior to win7 update btw)
