Details

When burnt to a CD the ISO is unable to automatically find itself during the bootup process. This results in it falling back to an interactive prompt.

This can be circumvented by mounting the disc drive manually to /run/archiso/bootmnt. After mounting you need to exit twice as the first time it would give an error about it being mounted; the second time you exit will actually boot the ISO.

The issue occurs under the December and October 2020 ISOs. Both were burned with an Acer branded Slim DVD burner, the firmware reports it as a Hitachi burner, and they were read from a Matsushita Desktop DVD burner. The motherboard is in UEFI only mode. I believe the October ISO was burnt using k3b; the December ISO was burnt using the built in Windows Burning Program.
This task depends upon

It may actually be an issue with the Matsushita burner as I've just tested it on the Acer and it boots no issue.

I've tested the Acer burners on two machines with the October ISO and it boots without issue.

I also have this issues trying to boot the ISO in a virtual machine. (Screenshot attached)

Earlier this week I also used the ISO to boot on a UEFI machine and I had no problem. So maybe it is only happening when booting with BIOS? (My virtual machine is booting from BIOS)

btw the Matsushita drive is a SW-9588-C manufactured in November 2006.
