hi
I want to install windows 8.1
here is the Error when i want to install:
"windows cannot be installed to this disk.the selected disk has an MBR partition table.On EFI Systems,windows can only be installed to GPT disk."
after that
I format My C partition drive,and now i have no OS :D
but nothing happened.
What should i do?
