Dualbooting windows and ubuntu (ubuntu is mostly working) and as in the picture, grub shows up in the boot order list as a bunch of gibberish.
Why is this? Could it hint at something wrong? How can I fix it even if just to make it look nicer?
I did have to restart the installation a bunch. Including once because it failed to create the partition, but the installation completed once that was done.
EDIT: I reinstalled grub and this persists so Im still curious.
I'm pretty sure Ubuntu works with secure boot. Debian 12 does and since Ubuntu is based off of that, you should be fine.
As for the blank name, it could be a grub bug or bios failing to detect names.
To test if the name works, boot (but don't install) a debian iso and see what name appears. It should show the device name.
If you choose to switch to Debian, a grub name "debian" should appear.
