Please read again what I wrote above, if the partition table is of the MBR type then the fdisk output is indeed "dos". > Booting from Gparted is showing: > Boot partition is - ext2 > swap > and root/ - ext4 > > I was thinking to boot strap the disk /dev/sda/ and partition it to GPT/UEFI > if I have gdisk installed on this computer. The UEFI MoBo firmware will not boot any .efi image from an ext2 partition. It requires a FAT32 partition in which GRUB must be installed: https://wiki.gentoo.org/wiki/EFI_System_Partition https://wiki.gentoo.org/wiki/GRUB https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Bootloader Don't forget to create a backup of your data, before you embark on this exercise.
