I have a dual boot Windows 10 + Ubuntu 18.04, I wanted to install Centos 7 which I did. That broke my Ubuntu boot!
- I deleted Centos 7 (partitions), deleted
/boot/efi/EFI/centosfolder/bootis in a different partition
- Ran
grub-mkconfig -O /boot/grub/grub.cfg - It keeps generating using
linux, initrdinstead oflinuxefi, initrdefi.
Why?
FYI, my secure boot is disabled in the bios.
I'd like to just delete the whole /boot/efi partition and reinstall grub and the config. Is that possible? How about windows 10's boot?
I wish grub's information was much cleaner, it's so confusing.
