[gentoo-user] Can't boot using UEFI

[-- Attachment #1: Type: text/plain, Size: 977 bytes --]

Hi list,

I've bought me a ultrabook dell vostro 5470, and I'm trying to get gentoo
running on it.

I'm having a few problems, but I'd like to correct the boot one first.

I'm installing it from ubuntu live cd, and the comand:

efibootmgr --create --disk /dev/sda --part 7 --label "Gentoo" --loader
"\boot\efi\boot\bootx64.efi"

seems to work. It put a entry on bios - Gentoo - but when I select it, the
windows start (second boot).

The handbook is not that clear, so I'm not sure if I should call /dev/sda7
of "--part 7". Other difference is I'm not using a separate /boot. Its
everything at /, so I'm also not not sure if this path is ok.

This seems to be the very simple, and I'd like to have it on my system. But
I've also tried grub2, and got the following error:

"grub2-install: error: cannot find EFI directory."

What should I do?

Thank you,

Have you tried gummiboot? AFAIR, it's a simple matter of doing:

gummiboot --path=/boot install

/boot should be yout EFI System Partition (ESP).

so you don't have an efi boot partition?

That would be your answer.

Volker, the efi is already working for Windows. I just want to create a new
entry. Is it really necessary to create a new partition?

Can you please tell us what this shows:

gdisk -l /dev/sda

or 

fdisk -l

assuming that /dev/sda is your drive.

If you are multibooting then gummiboot would be advisable, but GRUB will work 
too.

I think you have confused the too partitions EFI and /boot.

Your EFI boot code will jump to the FAT32 EFI partition.  In all likelihood 
this is /dev/sda1.  Unless you have some boot manager in there to point to 
your Linux partition at /dev/sda7 you will only boot what the EFI partition 
bootx64.efi code offers.  Presently the bootx64.efi in the EFI partition is 
the MSWindows boot code.  Create a back up if you intend to mess about with 
this, or you will need to use a MSWindows CD to recreate it with.

Clearly it can't find the appropriate EFI partition.  Have you mounted it?

you have to put your gentoo binary into that efi boot partition. And
tell efibootmgr to look there

OK, so this is your EFI partition, not /dev/sda7.

Mount /dev/sda1 and create your Linux-bootx64.efi in here.

Then set Gummiboot which will detect and list the different .efi boot files 
you have created.

I've Just installed grub2. It's ok for now. Gentoo is working and windows
isn't. I'll back to bootloader another time.

Thank you all for your tips :)
