TLDR...

Dells UEFI boot process ignores anything that is not exactly EFI\boot\bootx64.efi

I predict adding this to the host-installer will be low hanging fruit.

Relevant function is here: https://github.com/xcp-ng/host-installer/blob/master/backend.py#L1292

I believe a second invocation of grub-install using --removable may achieve this goal, but the side effects of it need to be verified to be sane.

We need to put that on our kanban backlog 👍

Done.

When this gets added will there be somewhere I can get a nightly ISO to test that the issue is resolved? Seeing as you need pretty specific hardware to encounter this issue.

Hi, yes we will provide a test ISO indeed! :)
Your tests and reports will be very helpful and appreciated!

Closing as fixed. Will be in the future updated installation ISOs.
