Hello 51lieal,
I’m afraid you might have linked the same thread twice, haha. I’ve checked out the thread, and I’m afraid I run into the same problems described in my original post. The file I am supposed to edit is not present in Qubes 4.1, and in Qubes 4.0, I am unable to edit the BOOTX64.cfg file without the file resulting in an unbootable file
So far I’ve been unable to find a thread explaining the steps you have to take to edit the BOOTX64.cfg file in Qubes 4.0 without the file becoming unbootable. The steps listed on the wiki: UEFI troubleshooting | Qubes OS do not seem to work for me. When I mount the USB and type sudo su -, and ls, I only see a file called anaconda-ks.cfg. I don’t seem to have write permissions for editing the BOOTX64.cfg file. When I edit the file like described in How to modify the Qubes-R4.0.4-x86_64.iso, it results in an unbootable file
