describe the problem

I was installing Arch Linux on my laptop using archinstal. It went smoothly, i set the partitions, added multilib and selected GRUB as my bootloader.
I booted into my newly installed distro, installing some essentials and using configuring it, and a problem occurred when I rebooted.

It couldn't boot into Arch using GRUB. In older versions of Archinstall, It used to boot after waiting on a BIOS error that says

>> Checking Media presence
>> No Media Present.

And would boot into grub after 15 seconds. I used to fix it by making the GRUB entry resemble Windows Boot manager. Well in this version of archinstall "latest", it just keeps deleting the GRUB boot entry every time i make it.

Yeah sure, it may be janky hardware but this issue doesn't happen when i use an older version of archinstall. I gave up on this method since it gave me permanent connectivity issues.

Any clue? feel free to ask for info.

Halo thanks for reporting this, think I might have left some code for the new UKI features that was breaking new way of handling grub. See previous PR #4073

Anyways should be just native support now :) And my bad
