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*

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>
