I have a HDD Momentus Thin (500GB) + mSATA Samsung (32GB) and I intend to install Ubuntu 13.04 in a UEFI - GPT - Secure Boot - Linux only System.

I'll set the "/" (root partition) to use the whole 500GB HDD (dev/sda) and I'll partition the mSATA (dev/sdb) like this:

  • sdb1 = EFI Partition (300MB)
  • sdb2 = SWAP (8GB)
  • sdb3 = EXT4 Volume (rest)

My question is: Do I need a "/boot" (Boot partition) even though my system is UEFI and I've already created an EFI Partition?

No, you do not need an additional, separate, /boot partition. /boot will reside on / on sda and that is fine.

  • So, the system will always have a "/boot" partition even if I have an UEFI PC + EFI Partition? In performance view, is it better to let the "/boot" reside on "/" in HDD or the best way is to create a separated "/boot" in the mSATA? – JChris May 30 '13 at 2:46
  • Your system will always have a /boot directory. The directory can be on a separate partition and mounted at /boot or not. There is no need for a separate /boot partition unless you are using LVM or encryption (luks) or some RAID – Panther May 30 '13 at 2:50
  • Thanks, I'll separete the "/boot", because I intend to encrypt the "/" and Swap using LUKS. I should point the "Device for boot loader installation" asked in Ubuntu's installation to the EFI partition (/dev/sdb1)? – JChris May 30 '13 at 3:01

    Correction: I should point the "Device for boot loader installation" asked in Ubuntu's installation to the EFI partition (/dev/sdb1) OR to the "/boot" partition? – JChris May 30 '13 at 3:11
  • Probably /dev/sda – Panther May 30 '13 at 5:03
