You are better off not removing the header. |

Are you running grub2-mkconfig from the chroot? The kernel+initramfs |
| 10 |
should be located at /boot. In the case of btrfs you can make it a |
| 11 |
subvolume but at the time of running grub2-mkconfig you should be chrooted |
| 12 |
into your root subvolume and your kernel has to be at /boot. |

From what I can remember you don't need any of that - if anything would be |
| 22 |
relevant it's subvol=rootfs but grub should be able to figure that out. |

/dev/sda1 is your EFI partition, formatted as vfat. You can have it |
| 35 |
mounted under /boot or under /boot/efi (I recommend the latter). Install |
| 36 |
like this |
| 37 |
|
| 38 |
# grub2-install --target=x86_64-efi --efi-directory=/boot/efi |
| 39 |
|
| 40 |
|
| 41 |
You can also use dracut to build an uefi executable that includes your |
| 42 |
kernel, the kernel commandline and the initramfs. |
| 43 |
|
| 44 |
# dracut --uefi |
