h1. UEFI загрузка
h2. Создаем новую таблицу разделов:
*gdisk /dev/sdb*
<pre>
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.
</pre>
*Command (? for help): o*
<pre>
This option deletes all partitions and creates a new protective MBR.
</pre>
*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*
<pre>
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
</pre>
*Command (? for help): w*
<pre>
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
</pre>
*Do you want to proceed? (Y/N): y*
<pre>
OK; writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.
</pre>
h2. Готовим ядро для загрузки через UEFI:
<pre>
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
</pre>
h2. Устанавливаем пакет для управления UEFI.
*/etc/paludis/keywords.conf*
<pre>
=sys-boot/efibootmgr-0.5.4 ~amd64
</pre>
*cave resolve -xz efibootmgr*
h3. Создаем нужные папки
*mkdir /boot/efi*
h3. Создаем ФС
*cave resolve -xz sys-fs/dosfstools*
*mkfs.vfat -F32 -n efi /dev/sdb1*
<pre>
mkfs.vfat 3.0.12 (29 Oct 2011)
</pre>
h3. Добавляем в fstab
*/etc/fstab*
<pre>
LABEL=efi /boot/efi vfat noatime 0 2
</pre>
h3. Пересобираем grub2 с поддержкой uefi-64
*/etc/paludis/use.conf*
<pre>
sys-boot/grub GRUB_PLATFORMS: efi-64
</pre>
*cave resolve -1xz sys-boot/grub*
h2. 2. Готовимся к первой загрузке через UEFI
Для работы с UEFI нужно чтобы ОС загружена через UEFI.
Это можно сделать через специальный UEFI shell.
h3. x86_64 UEFI Shell 1.0 (Old)
https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi
h3. 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'*
h3. Отключаем лишнее
*chmod -x /etc/grub.d/{20_linux_xen,30_os-prober,40_custom,41_custom}*
h3. Устанавливаем загрузчик по временной схеме (без прописки в UEFI)
*grub2-install --target=x86_64-efi --efi-directory=/boot/efi --removable --modules='part_gpt lvm'*
h3. Перезагружаемся через uefi shell (через BIOS)
Попадаем в UEFI консоль
<pre>
shell > fs0:
fs0> cd EFI
fs0> cd BOOT
fs0> BOOTX64.EFI
</pre>
h2. Устанавливаем по нормальной схеме:
*grub2-install --target=x86_64-efi --efi-directory=/boot/efi --boot-directory=/boot*
<pre>
BootCurrent: 0003
Timeout: 5 seconds
BootOrder: 0000,0003
Boot0003* UEFI: Built-in EFI Shell
Boot0000* gentoo
Installation finished. No error reported.
</pre>
h3. Удаляем старые загрузчики:
*rm -rfv /boot/efi/EFI/BOOT*
*rm -rfv /boot/grub/i386-pc*
h3. Перегенерируем конфигурацию grub2
*grub2-mkconfig -o /boot/grub2/grub.cfg*
<pre>
