I'm trying to setup my machine to dual boot Ubuntu and Windows 10. I have done this before on my primary PC, but I'm now running into issues doing this on my secondary machine with an older motherboard (specifically 760GM-P34(fx)).
I have Windows 10 installed (UEFI) and have a bootable flash drive that I've installed Ubuntu from by choosing "install Ubuntu alongside Windows 10 boot manager". The installation exited without error and appeared to have completed successfully. I now have both Windows 10 and Ubuntu installed on the same HDD.
On my newer machine (on which I have a functioning dual boot), booting into the GRUB menu was as simple as finding Ubuntu in the boot order and setting it to a higher priority than Windows boot manager. Unfortunately, things are not that simple on the older mobo; the BIOS boot sequence only displays the name of my hard drive, and I cannot see or edit the order of specific boot managers. I have followed many guides and scoured AskUbuntu: I have disabled FastBoot, I've executed bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
in hopes of switching the default boot manager, but I simply can't get anything to work.
It's perhaps worth noting that a screen displaying "2.2TB Infinity" appears after the BIOS screen exits that allows me to enter a boot menu. From there I only have the option to select my HDD, after which it boots straight into Windows.
What can I do to get to the GRUB menu? There is no option to choose Ubuntu/GRUB in my BIOS boot sequence or the 2.2TB Infinity boot menu, so I have no idea how I can access the GRUB menu. As stated, by default the HDD boots straight into Windows. Thanks
