What kind of prompt?

"Re-installing" bootloader has a different meaning with UEFI booting. One does
not
normally grub-install /dev/sda or /dev/nvme0n1 on UEFI systems.

The UEFI BIOS initiates boot by loading one or more files from the VFAT
filesystem, termed ESP, which mounts to /boot/efi/.

It's usually a good idea to disable CSM support (legacy/MBR booting), by
whatever
term your particular UEFI BIOS labels it.

Boot installation or rescue media in UEFI mode and provide us output from parted
-l, lsblk -f and efibootmgr -v, plus content of fstab.
