筆者今天上班時碰上了一個狀況. 就是機房的 SERVER 換顆硬碟, Ubuntu 不能開機, 這怎麼辦呢? 這個問題我後來使用了 UEFI 來解決. 如果 BIOS 有支援 UEFI, 我們可以使用 UEFI 開機. 什麼是 UEFI ? UEFI 是統一可延伸韌體介面（Unified Extensible Firmware Interface, UEFI）的縮寫, 是一種個人電腦系統規格, 用來定義作業系統與系統韌體之間的軟體介面, 作為BIOS的替代方案. 

 

UEFI SHELL

1. 首先 BIOS 設定 UEFI 開機.
 

2. 進入 UEFI SHELL ; 如下圖所示: 

3. 進入 BOOT PARTITION
 

Shell> FS0:

4. 進入 EFI\ubuntu 資料夾
 

FS0 :\> ls
...
09/04/15   07:07a <DIR>      512   EFI
...

FS0 :\> cd EFI\ubuntu
FS0 :\EFI\ubuntu> ls
...

5. 執行 grubx64.efi
 

FS0 :\EFI\ubuntu> grubx64.efi
...

STARTUP.NSH
 

 /boot/efi/startup.nsh

FS0:
cd EFI\ubuntu
grubx64.efi

 /boot/efi/startup.nsh

if exist FS0:\EFI then
  FS0:
  cd EFI\ubuntu
  if exist grubx64.efi then
    grubx64.efi 10
  endif
endif

Script for Building LOLLIPOP-SEATTLE ( mk-selinuxtarballs.sh )

下面這個 BUILD SCRIPT 也有用到 UEFI 唷.
