I have an MDR disk with Windows 8 installed and system reserved partition. I have tried installing Ubuntu from both disk and USB, and it just cannot pick up on my partition table either way. It thinks I have an empty disk.
I tried formatting, installing Ubuntu, and then Windows, but the exact same problem happened - Windows could only see an empty disk. When I have Windows installed, Windows installation media can see my partitions fine, and the same with Ubuntu.
I'm guessing this is because my Windows disk refuses to install in UEFI, and my Ubuntu disk refuses to install in BIOS. Why is this? I thought that either could install either way without a problem.
In my boot menu, I am offered two options:
- [UEFI] Sandisk
I assumed that the UEFI selection would install Ubuntu in UEFI, whereas the option without it would install in BIOS. They both seem the same to me, though - maybe I'm just being stupid.
