I used to have a W7 system in IDE, MBR and since I had to reinstall everything from sratch, I decided to set my drives to AHCI, UEFI/GPT. After install, I checked the BIOS settings and saw that in my Boot Options I had the "Windows Boot Manager" set as #1, my SSD set as #2 and DVD drive as #3.
When I change the boot priority and set my SSD as #1, my computer won't boot and asks for a bootable device although the system is install on my SSD. I don't have a multiboot system, there's only W7 present so why do I have a "Windows Boot Manager" in my BIOS? I thought it was only for multi boot systems so I don't get why it's showing up here.
When I go to msconfig, startup, there's only one system displayed (W7).
Since I'm new to AHCI/GPT, I don't know what's normal and what's not. If it's not normal, how come I got this Windows Boot Manager in my BIOS? Maybe the old MBR wasn't erased even though I ran a secure Erase on my SSD?
