GRUB issue after in-place upgrade to Mint 21

Post by zebop917 »

My system is a dual-boot with Windows 10 and previously Mint 20.3. After running mintupgrade, I can now only boot Mint 21 from the Advanced Options line of the grub menu. The regular option appears to be trying to boot a now non-existent Mint 20.3 (with non-existent kernel version 5.4.122). I've tried running a boot-repair session from a live USB but this can't seem to delete the grub2 files. Is there any other solution I could try?
