Installation not possible "Minimale BASH-like line ..."

[Pete]

Hi,

I suspect the same problem described here:

UEFI boot, "variable 'prefix' isn't set"

Attempting to install UCS 4.1 on a Beelink Z83 II, I’m experiencing a similar issue to the one described in Bug 39009. I’m getting this: Booting in insecure mode error: variable `prefix´ isn´t set. Loading step 1 …and then a grub prompt. I have tried a couple of workarounds mentioned in Bug 39009: I have removed /efi/boot from the ISO. This didn’t work because the Beelink Z83 II does not support legacy boot mode. There is no way to disable UEFI. I have tried installing UCS_3.2-4-UEFI-amd64.…

I stumbled across some other posts and bug reports describing this issue. It seems I’m not the only one having this one, is there any solution already?
