Hello, I have a navtive EFI machine, I could not find a way to manually boot in BIOS mode. I have disk already formatted with data and an MBR. I read in the fedora web site "f you are installing alongside an existing UEFI-native operating system, there should be an existing EFI system partition (it'll be a fairly small partition near the start of the disk, and the installer should identify it as an EFI system partition), and the neatest choice is probably to mount this existing EFI system partition at /boot/efi: it is perfectly safe and indeed intended for multiple operating systems to share an EFI system partition. You can create a new one instead, though, if you like, and this should work fine. " My understanding is that I should 1) have a partition EFI for /boot/efi that I can probably create with fdisk. 2) move to a GPT Here my present partition Number Start (sector) End (sector) Size Code Name 1 2048 33556479 16.0 GiB 8200 Linux swap 2 33556480 34580479 500.0 MiB 8300 Linux filesystem 3 34580480 149923839 55.0 GiB 8E00 Linux LVM 5 149925888 150949887 500.0 MiB 8300 Linux filesystem 6 150951936 266295295 55.0 GiB 8E00 Linux LVM 7 266297344 351651887 40.7 GiB 8300 Linux filesystem However, gdisk says: Warning! Secondary partition table overlaps the last partition by 33 blocks! You will need to delete this partition or resize it in another utility. Disk /dev/sda: 351651888 sectors, 167.7 GiB Does it mean that I need to repartition my disk (with gdisk?) In addition, I do not understand, "it'll be a fairly small partition near the start of the disk, and the installer should identify it as an EFI system partition" Why?
