I have had this system running perfectly for a year:
Asus p8z68 vpro
RAM 8 GB DDR3 1648 MHz
Corsair F60 SSD
Western digital 1 TB hard drive
Western digital 250 Gb hard drive
The issue is that I secure erased all of the hard drives with partition magic because I want to sell this computer on. I then installed windows and updated the SSD sandforce controller the latest version (2.4 I think).
Now the computer will not automatically boot past the American megatrends splash screen. It detects and list the mother board and detected devices. Then it says press f1 to run setup. I do this and can enter the boot menu and boot the hard dive no problem.
I have tried removing everything including all usb devices, the other hard drives, disabled everything that is not needed in the bios and of course I have the boot priority sorted. I have also cleared the CMOS with and without the battery. I'm now stuck.
I have a feeling the fix is in the EFI shell. Any suggestions or help greatly appreciated.
