What 's Mean ?Create a mebibyte partition {+1MiB with gdisk) on the disk with no file system and type ef02 (or bios_grub in parted). This partition can be in any position order but has to be on the first 2 TiB of the disk. This partition needs to be created before GRUB installation.

跟下面兩個描述是一樣的Doesn't Need ESP Partition? Why?
Create a mebibyte partition {+1MiB with gdisk) on the disk with no file system and type ef02 (or bios_grub in parted). This partition can be in any position order but has to be on the first 2 TiB of the disk. This partition needs to be created before GRUB installation.

1-1. 如果 開機硬盤 是 GPT 一定要 efi 分区
efi 分区 在硬盘第一个分区 是 比較建議的選擇 不是必須的選擇
1-1-2. 如果是 Legacy Bios 開機
efi 分区 掛載在 (空白 不要填 讓安裝程式自動決定)
分割區型態 bios_grub (稱為 BIOS boot partition)
EFI(sda1),/boot(sda2), / (sda3) , /usr (sda4), /var (sda5)

1. 你原來 /dev/sdb 安裝 並沒有確定能成功開機my idea:
1. sudo fsarchiver -v restfs /dev/sd....
2. https://help.ubuntu.com/community/UEFIB ... FI_systems ==> follow this..
1. UEFI enabled 硬盤必須是 GPTMy computer has UEFI mode
I want to Install Ubuntu In UEFI mode...(Install to SSD)
My SSD has GPT ...
所以 /dev/sda1 格式化成 fat32 掛載在 /boot/efi1-1. 如果 開機硬盤 是 GPT 一定要 efi 分区
efi 分区 在硬盘第一个分区 是 比較建議的選擇 不是必須的選擇
1-1-1. 如果是 uefi enabled 開機
efi 分区 掛載在 /boot/efi
efi 分区 分割區型態 fat32
4. grub 2 安裝到 /dev/sda 不是分割區/dev/sda1 at32 /boot/efi
/dev/sda2 ext4 /boot
/dev/sda3 ext4 /
/dev/sda4 ext4 /usr
/dev/sda5 ext4 /var
/dev/sda6 ext4 /diskdata # diskdata 可以自己取名
/dev/sdb3 ext4 /home

恭喜现在已经把ubuntu14.04安装到了ssd中.
能夠描述一下 做了哪些優化 ?对ssd也做了一些优化.
