Talk:Undead USB Install

updating to both uefi & legacy mode sandbox

https://www.funtoo.org/Talk:Install/GPT_Partitioning <--correct partitioning to load legacy mode, and uefi mode.

rest of the drive jfs partition name root partition label root.

root # mv /etc/fstab /etc/fstab.backup
root # echo "LABEL=boot /boot vfat noauto,noatime 0 2" >> /etc/fstab
root # fatlabel /dev/sdc2 "boot"
root # jfs_tune -L "root" /dev/sdc3

stab 2 at getting uefi going from legacy machine.

root # mkdir /boot/efi
root # mount /dev/sdc1 /boot/efi
root # grub-install --target=x86_64-efi /boot/efi

/boot/efi/efi/gentoo/grubx64.efi is generated. doesn't load probably secure boot unsigned image or something like that.

stab 3 gpt partitioning via official install method gdisk. testing legacy grub + gpt to verify that MBR can be deprecated.

legacy loaded grub this time from a gpt partition. i think i didn't delete the fstab defaults, it wasn't mounting root correctly but very close to running.
