while I don't have any of those machines readily available, i am curious if this USB image [1] would work. It's a lightly customized Alpine which can be written to a flashdrive using either Rufus, usbimager, or this command: xz -dkc <asm.usb.xz >/dev/sdi
the image was built using this repo [2] and this command: ./build.sh -i dl/alpine-standard-3.19.0-x86_64.iso -p min -s 0.3
Would've been happy to try this, but this device has already been shipped to the recipient. FWIW the consensus was that Secure Boot on the Inspiron was still partially active, even after disabling it in BIOS. If this image is capable of running with Secure Boot enabled, then it should work. If it requires disabling Secure Boot, then it probably wouldn't.
In that case we probably have the answer already :) The next question then would have been whether secureboot-signing it yourself and replacing the PK/DB in the BIOS would have made it work, but it's really unfortunate that we've gotten to this point.
Yeah. I was genuinely surprised at how hostile the process has become. These were the most difficult installs I've ever had by far, and for entirely different reasons than in the past. Contrary to past installs, once I finally got the OS on there, everything else worked better than expected.
