Grub config on hassoss

I’m trying to get rid of the A/B boot options from grub. The B option can’t boot so i dont want it to be tried at all anymore
tried to edit the grub.cfg, but it’s not helping. Grub commands dont seem to be present on the hassos image.

anyone a suggestion to get rid of B tried at any time?

Hello, editing of grub config file worked for me. My location was:

/mnt/boot/EFI/BOOT/grub.cfg

Can you elaborate how ?

So far I had to do it from the local machine; attach KB and display.
May be possible remotely; unsure.
At the local “ha” prompt, type “login” then enter.
Then you can use vi to edit said file:
vi /mnt/boot/EFI/BOOT/grub.cfg
vi is not too easy, but not too hard.
