UEFI загрузка¶

Создаем новую таблицу разделов:¶

gdisk /dev/sdb

GPT fdisk (gdisk) version 0.8.4

Partition table scan:
  MBR: not present
  BSD: not present
  APM: not present
  GPT: not present

Creating new GPT entries.

Command (? for help): o

This option deletes all partitions and creates a new protective MBR.

Proceed? (Y/N): y

Command (? for help): n

Partition number (1-128, default 1):
First sector (34-488395021, default = 2048) or {+-}size{KMGTP}:
Last sector (2048-488395021, default = 488395021) or {+-}size{KMGTP}: +195M
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): EF00
Changed type of partition to 'EFI System'

Command (? for help): n

Partition number (2-128, default 2):
First sector (34-488395021, default = 401408) or {+-}size{KMGTP}:
Last sector (401408-488395021, default = 488395021) or {+-}size{KMGTP}:
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): FD00
Changed type of partition to 'Linux RAID'

Command (? for help): p

Disk /dev/sdb: 488395055 sectors, 232.9 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 47C154D0-7F67-4EDB-8871-9C80E6836A6F
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 488395021
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048          401407   195.0 MiB   EF00  EFI System
   2          401408       488395021   232.7 GiB   FD00  Linux RAID

Command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.

Готовим ядро для загрузки через UEFI:¶

CONFIG_EFI=y
CONFIG_EFI_STUB=y
CONFIG_RELOCATABLE=y
CONFIG_FB_EFI=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_EFI_PARTITION=y
CONFIG_VFAT_FS=y
CONFIG_EFI_VARS=m

Устанавливаем пакет для управления UEFI.¶

/etc/paludis/keywords.conf

=sys-boot/efibootmgr-0.5.4 ~amd64

cave resolve -xz efibootmgr

Создаем нужные папки¶

mkdir /boot/efi

Создаем ФС¶

cave resolve -xz sys-fs/dosfstools

mkfs.vfat -F32 -n efi /dev/sdb1

mkfs.vfat 3.0.12 (29 Oct 2011)

Добавляем в fstab¶

/etc/fstab

LABEL=efi   /boot/efi  vfat    noatime   0 2

Пересобираем grub2 с поддержкой uefi-64¶

/etc/paludis/use.conf

sys-boot/grub GRUB_PLATFORMS: efi-64

cave resolve -1xz sys-boot/grub

2. Готовимся к первой загрузке через UEFI

Для работы с UEFI нужно чтобы ОС загружена через UEFI.
Это можно сделать через специальный UEFI shell.

x86_64 UEFI Shell 1.0 (Old)¶

https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi

x86_64 UEFI Shell 2.0 (Beta)¶

https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/ShellBinPkg/UefiShell/X64/Shell.efi

Выбираем 1.0 (Old)

wget -O /boot/efi/ShellX64.efi 'https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi'

Отключаем лишнее¶

chmod -x /etc/grub.d/{20_linux_xen,30_os-prober,40_custom,41_custom}

Устанавливаем загрузчик по временной схеме (без прописки в UEFI)¶

grub2-install --target=x86_64-efi --efi-directory=/boot/efi --removable --modules='part_gpt lvm'

Перезагружаемся через uefi shell (через BIOS)¶

Попадаем в UEFI консоль

shell > fs0:
fs0> cd EFI
fs0> cd BOOT
fs0> BOOTX64.EFI

Устанавливаем по нормальной схеме:¶

grub2-install --target=x86_64-efi --efi-directory=/boot/efi --boot-directory=/boot

BootCurrent: 0003
Timeout: 5 seconds
BootOrder: 0000,0003
Boot0003* UEFI: Built-in EFI Shell 
Boot0000* gentoo
Installation finished. No error reported.

Удаляем старые загрузчики:¶

rm -rfv /boot/efi/EFI/BOOT
rm -rfv /boot/grub/i386-pc

Перегенерируем конфигурацию grub2¶

grub2-mkconfig -o /boot/grub2/grub.cfg
