Lenovo X1 Carbon Gen 6 only creates bootable install when installer is booted with Legacy mode

[Ranguvar]

Qubes OS version:

4.0-rc5

Affected component(s):

System boot after booting and running installer using UEFI boot

---

Steps to reproduce the behavior:

Boot Qubes installer using UEFI with or without CSM enabled.
Install, completely wipe target disk, no changes to settings beyond encryption.

Expected behavior:

Successful boot of installed USB media.

Actual behavior:

Attempt to boot USB using UEFI (CSM off/on) or Legacy mode - both return to the boot select screen after a second.

Boot Qubes installer using Legacy mode.
Created USB now boots.

General notes:

I'm going to use Legacy boot to install to a USB and use Qubes like this, but it is annoying to switch between UEFI CSM off (for Windows and normal Linux) and Legacy for Qubes.

I did check to ensure the install media has the perfect checksum.

Please let me know if I can provide any relevant information.

Are you installing to external USB? See https://www.qubes-os.org/doc/uefi-troubleshooting/#boot-device-not-recognized-after-installing

And better use qubes-users mailing list for this type of problems.
