I'm trying to install Linux from a live CD (Elementary OS)
I set my boot priority order so that CDROM was first in the BIOS.
However my PC always chooses to load my SSD drive instead.
To check that the live CD is working correctly I unplugged all my drives EXCEPT my CDROM drive.
With this configuration the CDROM boots and I'm able to trial Elementary OS.
Upon plugging the SSD back in, the SSD always loads first.
I have checked my BIOS at least 3 times and I am ensuring that CDROM is the first to boot. I have also attempted to load CDROM via the boot selector after post (via f12). Still, it loads the SSD instead. So I KNOW for sure my live CD is bootable and works correctly.
It's bizarre! I know the live CD works and I have triple checked the boot order, but it simply will not load if my SSD is plugged in..
Extra info which may help
On the SSD I already have a dual boot setup with ubuntu and windows 7. I wonder if somehow this could effect the boot order. I don't really know how....
Is there something else I'm missing? can MBR's somehow override BIOS boot order?
My motherboard is a Gigabyte GA-970A-UD3
- I checked my cdrom drive for a master slave jumper on the back. There are no jumpers. This is a SATA drive
- I swapped the SATA connectors on the motherboard so that the CDROM is plugged into the first SATA port, still the hard drive loads instead of CDROM
- The BIOS version is AMD ACHI version 3.07
