Move Ubuntu 14.04 Desktop ESP partition15.08.2014
Ubuntu
0 Comment

The following article describes how Ubuntu 14.04 is installed on the same HDD having Windows 7 already installed, Ubuntu 14.04 using use a separate ESP partition.

For the following article …

  • Ubuntu 14.04 Desktop = U1404
  • Windows 7 = W7

All said below is probably also true for for different OSs, but I used W7/U1404.

So … the initial situation is …

  • An UEFI motherboard
  • HDD initialized using GPT

A HDD connected to an UEFI motherboard is usually only using one single ESP partition. All installed OSs use the same ESP partition to store their respective bootloaders. However, there are situations where an ESP partition per installed OS is an advantage.

That’s the case for me. I use image backups for W7 and U1404 partitions, both OS backups include their respective ESP partition. Assuming if there was only one common ESP partition and the OS image backups would include this common ESP partition, there is a potential risk for data inconsistency of the ESP partition after an image restore in case of an OS update from another installed OS the image restore was done. Ok … complicated … I explain …

An example …

  1. W7 is backed up (system + common ESP partition)
  2. U1404 is backed up (system + common ESP partition)
  3. W7 update changes the bootloader in common ESP partition
  4. U1404 is restored

In this scenario, U1404 image restoration also restores an outdated W7 bootloader located on the common EFI partition, hence creating possible W7 boot problems or other issues which might be related to this outdated bootloader. Also, future W7 updates won’t detect the outdated bootloader since for W7 update mechanisms, the update took already place.

U1404 installation process doesn’t allow selecting an existing ESP partition the bootloader is supposed to be copied to. It simply uses the first EFI partition found in the GPT. An UEFI entry is also done accordingly, id est the U1404 UEFI entry points to this ESP partition. A existing second ESP partition is ignored by the U1404 installation process.

ubuntu forums : Install 14.04 Desktop with second EFI partition
(in fact, I should have called it “Install 14.04 Desktop with second ESP partition”)

Now … if a second EFI partition is used, 3 things need to be done:

  1. U1404 bootloader needs to be moved to second ESP partition
  2. /etc/fstab needs to be adjusted accordingly
  3. UEFI also needs to learn about location of the second ESP partition

1. U1404 bootloader needs to be moved to the ESP partition

“Ubuntu 14.04 ESP”, “Ubuntu 14.04” and “Linux swap” partitions are created (using gdisk) before U1404 is installed. This is how the HDD looks like:

root@ubuntu:~# gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.8

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help):

Partition 1 – ESP partition used by W7 and initially U1404 prior ESP move to partition 5
Partition 2 – MSR partition used by W7
Partition 3 – W7 system partition
Partition 4 – Data partition (not relevant in the context of this article)
Partition 5 – ESP partition which will later be on used by U1404
Partition 6 – U1404 system partition
Partition 7 – U1404 swap partition

Now, U1404 is installed. Both ESP partitions look like this (the new ESP partition /dev/sdb5 first needs to be mounted):

2. /etc/fstab needs to be adjusted accordingly

The UUID of /boot/efi is changed from /dev/sdb1 to /dev/sdb5. blkid tells us about the UUID.

3. UEFI also needs to learn about the new location of the EFI partition

This is how UEFI looks like before U1404 was installed. U1404 USB installation device was used to produce code block below.

The only change is Boot0001. The U1404 USB installation device entry was replaced by the just installed U1404.

Boot0000 : Windows Boot Manager
Boot0001 : U1404 HDD installation, still pointing to first ESP partition
Boot0002 : Points to empty second ESP partition (/dev/sdb5) [ generated by UEFI boot process ] Boot0003 : Points to empty second ESP partition (/dev/sdb5) [ generated by UEFI boot process ] Boot0004 : ? [ generated by UEFI boot process ] Boot0006 : CD/DVD Drive [ generated by UEFI boot process ]

Now, the bootloader is moved from /dev/sdb1 to /dev/sdb5 (point 1. above) and /etc/fstab adjusted accordingly (point 2. above). From now on, Boot0001 “ubuntu” doesn’t start U1404 anymore since it doesn’t find shimx64.efi – though it starts W7, which is somewhat unexpected! Nevertheless, Boot003 “UEFI: Samsung SSD 840 PRO Series” starts U1404.

Hence … (a.) Boot0001 can be deleted and (b.) a new U1404 entry can be created if desired (since it doesn’t do much else than the existing Boot0003 entry).

After next reboot, Boot0003 entry was gone. UEFI seems to detect at boot process that it is a double entry doing the same thing, and consequently deleting the self-made generic entry “Boot0003* UEFI: Samsung SSD 840 PRO Series”. Not bad!

Some fine tuning. The boot order should be 0000, then 0001 and the timeout 3 seconds. The is achieved as followes:

root@deimos:~# efibootmgr -o 0,1 -t 3
BootCurrent: 0001
Timeout: 3 seconds
BootOrder: 0000,0001
Boot0000* Windows Boot Manager
Boot0001* Ubuntu 14.04
Boot0002* UEFI: Hard Drive 
Boot0004* Hard Drive 
Boot0005* CD/DVD Drive

The W7 is my default OS, this is the optimal solution. If I would like to use U1404, I press F12 during boot process and the UEFI menu shows up and allows me to choose the boot device.

BTW … my last update from today (15.08.2014) still doesn’t contain a bootloader update. Let’s see if this continues like that …

md5sum checksums of U1404 initially installed bootloaders (from original distribution):

root@deimos:~# md5sum /boot/efi/EFI/ubuntu/*
e325709285f9535445b9dba5eb4ebb77  /boot/efi/EFI/ubuntu/grub.cfg
