Hi, so far it was easy to install and run Qubes OS 4.0 RC3 (and RC2) on this hardware - as long as I keep boot mode on "Legacy Only".
However, the TPM chip on this hardware works in UEFI boot mode only; and even with secureboot disabled and CSM support enabled, I can't get Qubes OS to boot in UEFI mode: - The installer doesn't run in UEFI mode (I get text mode grub, but whatever i select simply does nothing and returns to grub) - If I turn UEFI mode on after installing Qubes OS, I don't even get grub. - I tried the UEFI troubleshooting guide to no avail, although I was unable to run efibootmgr directly while in legacy boot mode ("EFI variables are not supported on this system") so in order to run efibootmgr, i booted a separate Fedora 26 Live image which does boot in UEFI mode. However, even with updated records, the result is the same: selecting those options from the UEFI boot menu simply makes the screen flicker once and then i'm back in the UEFI boot menu. - I tried copying the EFI and CFG file to /EFU/BOOT and renaming them to BOOTX64.EFI and .CFG, and also created new entries with efibootmgr for this, again without success. I also tried installing Qubes OS 3.2 on this system which didn't work and initial troubleshooting failed; but I'd like to concentrate my efforts on making this work for Qubes 4.0 so i didn't spend too much time on getting Qubes OS 3.2 on the T470. Any hints about troubleshooting the UEFI boot option are appreciated; i can also provide more exact details about what i already tried. Given the specs of this machine, I'm really determined to not give up easily. For now, I'll test other functionality in legacy mode only.
