Ever since I have removed Ubuntu from my HP 15s-eq247ng Laptop and installed Debian on it, I had issues with the boot entries. It had kept the Ubuntu entries in the beginning until one day I must've forcefully got rid of them.
Currently, the EFI files for GRUB exist, but I have to interrupt the boot every time to select the correct file. I have tried to fix this issue with efibootmgr and it looked like it fixed it, until I rebooted my computer. It looks like this issue is most commonly related to dual-boot environments. There is, however, just one operating system installed on my machine. Also, secure boot is greyed out and on disabled for me.
This is what I tried:
root:~# efibootmgr
