More kernel panic

Hi, i tried that after searching the forums but it doesn't work for me.
after booting into 6.17, the next time i boot it's still going default for 7.0

Hi i tried the GRUB_DEFAULT and GRUB_SAVEDEFAULT thing before, and while it shows a * next to 6.17 it still loads 7.0 when i just choose zorin os in the boot menu.

is there a way i can set the first boot menu option to 6.17?

I dont have dual boot with another linux, just windows for when i need it.
