The above implies an MBR partition table approach to booting your OS, which a non-UEFI (BIOS only) MoBo will need. However you are meant to be using UEFI *only* and GPT ... > 2 3146kB 137MB 134MB ext2 boot boot, esp and this partition is what should be used for an UEFI MoBo, but the fs is wrong. Change it to fat32 and check with gdisk that its partition code is EF00, which according to your 'boot, esp' flags it should be. This is your EFI System Partition (ESP). > 3 137MB 4429MB 4292MB linux-swap(v1) swap > 4 4429MB 5503MB 1074MB root > 5 5503MB 1000GB 995GB vg > > Partition-1 was created like this: mkfs.fat -F 32 -n efi-boot /dev/sda1 > Partition-2 was created like this: mkfs.ext2 -T small /dev/sda2 > > GRUB_PLATFORMS was set to "efi-64" in make.conf before emerging grub:2 > > /boot and /boot/efi is mounted like this > # mount | grep boot > /dev/sda2 on /boot type ext2 (rw,relatime,errors=continue,user_xattr,acl) > /dev/sda1 on /boot/efi type vfat > (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mi > xed,errors=remount-ro) > > I had to remount /sys/firmware/efi/efivars in rw-mode, otherwise > grub-install would complain. Yes, this has been the case for some time now. You will always need to remount it as rw before you change the contents of the ESP boot partition. It is also mentioned here: https://wiki.gentoo.org/wiki/GRUB2 > grub-install was run like this > "grub-install --target=x86_64-efi --efi-directory=/boot/efi" But ... /boot/efi is not your ESP. > And "grub-mkconfig -o /boot/grub/grub.cfg" has been run without any errors. > > efibootmgr shows my gentoo as the first entry > # efibootmgr > Timeout: 1 seconds > BootOrder: 0000,0001,0002,0003 > Boot0000 gentoo > Boot0001 Hard Drive > Boot0002 Network Card > Boot0003 UEFI: Built-in EFI Shell Use 'efibootmgr -v' to check the path of the .efi image it tries to boot and check the path is correct without any typos.
