I have looked through many of the questions, and haven't found anything that quite satisfies this problem. I have an ssd hard drive that is bootable from my old computer. It is a standard BIOS, however, I built a new computer with Z87 motherboard that is a UEFI. What I'd like to do is boot from this hard drive without wiping out the hard drive. I've tried booting from legacy mode, doesn't seem to work. Part of the multitude of problems is my partitioning scheme, which is GPT. sdx1 is the btrfs system, sdx2 swap, sdx3 is bios_grub.
I've tried setting the UEFI/BIOS to boot in legacy mode, I've tried turning my swap partition into a Grub EFI boot, I've tried copying the file system onto a new drive installed on the new system. However, copying the information doesn't keep the filesystem or subvolumes intact. I've also tried boot-repair which is when I overwrote the swap space. I'd really rather not start over on a new install, so any other suggested trees to bark up would be appreciated.
For the record, I hate you Microsoft, and ASUS I understand complying with microsoft, but make it optional... I'm really disappointed in that I have to deal with Windows 8 when I have nothing to do with it.
Something I think I could try, but would like to hear from more experienced users. Moving the sdx1 (btrfs /@/@home) partion and opening up a 100 MB partition on the beginning sectors and install efi compatible Grub2 installation. Would it work? How to move a partition?
