I’m still having some trouble, but I did try using Boot Repair, and here’s the new report it generated: https://paste.ubuntu.com/p/VnG78GvsH5/.
When I went through it, I noticed this message:
"Locked-NVram detected. Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.4 LTS entry (sda1/efi/ubuntu/grubx64.efi file)!"
Could this be related to the issue I’m facing? And if so, would you have any advice on how I can go about fixing it? I already have ubuntu as my top priority for booting in the BIOS, but I don't know if that's exactly what this is referring to. Thanks!
Thank you so much for your help!
