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.
\n
\nFor the following article …<\/p>\n
All said below is probably also true for for different OSs, but I used W7\/U1404.<\/p>\n
So … the initial situation is …<\/p>\n
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.<\/p>\n
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 …<\/p>\n
An example …<\/p>\n
In this scenario, U1404 image restoration also restores an outdated W7 bootloader located on the common EFI partition, hence creating possible W7 boot problems or other issues which might be related to this outdated bootloader. Also, future W7 updates won’t detect the outdated bootloader since for W7 update mechanisms, the update took already place.<\/p>\n
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.<\/p>\n
ubuntu forums : Install 14.04 Desktop with second EFI partition<\/a> Now … if a second EFI partition is used, 3 things need to be done:<\/p>\n 1. U1404 bootloader needs to be moved to the ESP partition<\/b><\/u><\/p>\n “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:<\/p>\n Partition 1 – ESP partition used by W7 and initially U1404 prior ESP move to partition 5 Now, U1404 is installed. Both ESP partitions look like this (the new ESP partition \/dev\/sdb5 first needs to be mounted):<\/p>\n Now … let’s move the \/EFI\/ubuntu (U1404 bootloader) directory from \/boot\/efi to \/mnt\/esp2.<\/p>\n 2. \/etc\/fstab needs to be adjusted accordingly<\/b><\/u><\/p>\n The UUID of \/boot\/efi is changed from \/dev\/sdb1 to \/dev\/sdb5. blkid tells us about the UUID.<\/p>\n 3. UEFI also needs to learn about the new location of the EFI partition<\/b><\/u><\/p>\n This is how UEFI looks like before U1404 was installed. U1404 USB installation device was used to produce code block below.<\/p>\n Boot0000 : Windows Boot Manager First, the efibootmgr help (no option for help ?!?!):<\/p>\n This is how UEFI looks like after U1404 was installed. U1404 USB installation device was removed and HDD installed U1404 used to produce code block below.<\/p>\n The only change is Boot0001. The U1404 USB installation device entry was replaced by the just installed U1404.<\/p>\n Boot0000 : Windows Boot Manager 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.<\/p>\n 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).<\/p>\n 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!<\/p>\n Some fine tuning. The boot order should be 0000, then 0001 and the timeout 3 seconds. The is achieved as followes:<\/p>\n 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.<\/p>\n BTW … my last update from today (15.08.2014) still doesn’t contain a bootloader update. Let’s see if this continues like that …<\/p>\n md5sum checksums of U1404 initially installed bootloaders (from original distribution):<\/p>\n md5sum checksums of U1404 from today (after U1404 updates):<\/p>\n References:<\/b><\/u><\/p>\n Please comment and\/or correct … Thanks!<\/p>\n","protected":false},"excerpt":{"rendered":" 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…. <\/p>\n
