Hello everyone, I use the opensuse 42.2 and my grub and boot screen are the same as the image from my opensuse 42.1. How do I fix both? I have no more manjaro in hd and it still appears on the bios boot screen.
To update grub2 menu, boot into openSUSE and run “update-bootloader --refresh”. This assumes you actually overwrote Ubuntu partition so it has different content or is not mountable.
For BIOS - you should have some options to delete boot entries in BIOS setup. If not, it depends whether you boot openSUSE in legacy BIOS or EFI mode. Do you have /sys/firmware/efi directory in openSUSE?
