I recently had the logic board in my 27" iMac replaced. Everything works beautifully, except my Boot Camp install. Using my Quicksilver script to reboot into my Windows 7 partition I am presented with a solid gray screen for several minutes before the system automatically restarts into OSX. When booting with the option key held down, the screen stays stuck on the disk selection screen after selecting the Windows partition. Then, as with before, the system automatically reboots into OSX. Has anyone had a similar issue? My assumption is to use the Windows disk and do a repair installation, but I was trying to prevent this as the disk is currently unavailable and I need to access some applications as soon as possible.
