A workaround [1] (adapted from the respective mailing list submission [2] with minor edits) has been submitted to mainline Linux and was just released as part of Linux v6.8-rc7. Automatic backports into Linux 6.1, 6.6, and 6.7 are pending.
I'll submit separate linux-stable backports for 5.15, 5.10, 5.4, and 4.19 (required due to changed paths) once we get the first stable release on 6.8, that should be ample time for figuring out whether the approach introduces any issues.

Two weeks back, I installed a Live-USB with Ubuntu 14.04. All working well, but I struggled getting it persistent, so I decided to do a full Ubuntu installation to another USB-drive. Leaving my Windows hard drive untouched. What I did: 1) I entered my "BIOS" to change boot order, and booting from my Ubuntu Live-USB. 2) I tried following the installation guide https://help.ubuntu.com/community/Installation/UEFI-and-BIOS, but sizes were changed to: - 1MB BIOS Boot (pretty sure I left this unformatted,but it now reports as Ext4) - 666MB EFI System, FAT32 - 30GB Linux Filesystem, Ext4 - 999MB Linux Swap, Swap 3) I installed Ubuntu on a second USB-drive. Leaving my Windows hard- drive "intact" (?) The result: Now, I can only boot my machine by inserting my second full-installation-USB-drive. I cannot boot Windows, and I cannot boot from my LiveUSB. If I boot without inserting my full-installation-USB-drive, I get the boot screen telling me I can press F2 or F12. However, none of these have any effect, apart from making the beep. Then the computer enters the "Boot menu" (as well as the second menu "Application menu").
