MBR partition table, only GPT disk
Last week or so, I posted a thread about my MacBook having no DVD drive. It is MBP 13" Early 2011.
I was able to boot from external DVD drive (my original DVD drive is no good) and USB to install Windows 8.1.
The error message I have while before installing Windows 8.1 was as follows: WIndows cannot be nstalled on this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed on GPT disks.
My main harddrive is a SSD, Samsung SSD 850 PRO 256GB. Do I have to reformat the whole thing and make sure it doesn't format as MBR? I think this is no brainer, based on what I've researched. I just need confirmation. I'm still struggling to install Windows and it has been exhausting. The error message was the exact same when I was able to burn Windows 8.1 ISO to DVD and boot from DVD.
Any help will be greatly appreciated. Thanks.
MacBook Pro (13-inch Early 2011), OS X El Capitan (10.11.3)
