As the title Says.. Im trying to install a New OS on a Laptop with Uefi(Pre-installed Windows 8). I have a Entry-Mid Level knowledge on Installing OS and stuff..but almost New to Uefi. so what i did what Change the Boot from Uefi to Legacy then Booted into the OS installation.When i reach the Partition Part. it says that the following Hard Disk was a GPT..as far as i know. you cant boot make that HDD Bootable anymore or so i know. Its the MBR thats can be bootable,, so Any Tips? Thanks in Advance
