I struggled for days … pre-OS boot problems give me nightmares, no logs, output just flows by if there’s even one … playing around with partition schemes … Prelude My Knowledgeįairly familiar with grub.cfg, able to click-through BIOS. It uses a new descendant of BIOS called UEFI, which requires Grub2, which is beta. I received a brand new laptop with bleeding edge hardware on Monday. I’m writing this done because I see myself halfway through it and want to take notes.
Todo: Rewrite this now that I know how to do this simple. Then you have to resort to one-time using the EFI-shell (search below) to boot the kernel, then use efibootmgr (search below) to place the boot-option. If you’re lucky, your UEFI has a nice gui to select the kernel and set boot options – my gui is crap and has a wrong help info too! The only tricky part is putting your kernel as new boot option into the UEFI-bios. Just follow the handbook on Gentoo installation and make sure your kernel is EFI-bootable (rtfm).įorget about boot-loaders, although you should know the kernel options that you would put into grub.cfg (root=, initrd, etc.) UEFI is actually really cool, you don’t need GRUB2 or any bootloader!
The info below are my scrambled notes taken when I hit the problem.
Read my articles at the Pentoo WIKI for pretty examples on how to tackle UEFI.
