I want to dual boot Linux Mint with my Windows 8.1 installation right now. What I didn't realize is you can't install an OS on a logical partition. I have the three partitions already for primary. I can copy my steam partition and back it up and make it a logical partition but I really don't want to do that again. I already backed it up just to extend it about a week ago and it took a really long time and I'd rather not do it again. So I have 3 primary partitions and 50gb unallocated space that I would be using for Mint. Is it safe to remove the System Reserved drive? What exactly does that contain? I am using legacy boot (in my BIOS settings I changed it to that, and it's been like that since before I installed Windows 8 on it) so it's not UEFI. What are my options to get a freed primary partition to use for mint?
