Can't boot my parrot OS after upgrade.

No man
Boot again from p10
And run command
update grub
grub update
Amd sorry i forget to say in past post

Still same problem…no luck again

reinstall, i dont agree with the kernel deleting advice but thats where @Amzker and I differ, i would have just changed res and then rebooted into 20. ive never seen this error on my machine tho its kinda odd
