I recently installed Win7 x64 on my Sandisk Extreme 120GB and the system worked well. Then one of my other programs started locking up, so I decided to clean the SSD and re-install Win7 x64. (My motherboard is EFI)
The Win7 disk will not re-install on the SSD, and I receive the following error message: “The disk has an MBR partition; on an EFI system it can only install to GPT disks.”
When I try to use Disk Management to change the SSD drive to GPT, the option is grayed out.
Please advise how I can re-install Win7 x64 to my SSD.
