Can the left side of the Arch Linux EFI partition be moved?

I installed Windows 10 giving it less space than I probably should have and I was just wondering if on an UEFI system if the left side of the Arch Linux partition can be moved to the right?
I've moved the right side before with no issues but, I understand moving the left side can be a big deal.

I'm only asking this because I have a friend that moved the left side of Arch with Gparted and it would not boot. He had to re-install it. That was on a MBR partitioned system.

I've got about 30GB spare on Windows 10 and could just use my 2TB RAID0 SATA drive for anything else I need to install if I cannot move Arch.

Any helpful insight would be appreciated.

There souldn't be a problem, but be prepared with a backup. So if things go wrong just remake the partition wherever you like and cast the backup in it. The kernel will find the new partition, if all moving has gone right.

What do you mean by the 'Arch Linux EFI partition'?

You should only have one EFI partition for all of your OS's.


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Are you fairly sure about this? Do you know that is has worked firsthand?

Thanks for the reply.

I 'm talking about the partition that contains Arch, mount point is / - scd6.

[cavsfan@ArchLinux ~]$ lsblk | grep sdc
sdc       8:32   0 447.1G  0 disk 
├─sdc1    8:33   0   550M  0 part /boot
├─sdc2    8:34   0    16M  0 part 
├─sdc3    8:35   0   150G  0 part 
├─sdc4    8:36   0   466M  0 part 
├─sdc5    8:37   0     4G  0 part [SWAP]
├─sdc6    8:38   0   155G  0 part 
├─sdc7    8:39   0  42.1G  0 part 
├─sdc8    8:40   0    40G  0 part 
└─sdc10   8:42   0    35G  0 part /Media

Perhaps sdc1 is the one you are referring to.

I'm booting Arch Linux, Windows 10 and openSUSE Tumbleweed and they all have entries in sdc1.

Thanks for the reply.

Re: Can the left side of the Arch Linux EFI partition be moved?

You have your terminology incorrect, sdc1 is your EFI partition, sdc6 is your Arch root partition.
That's why I got confused, as EFI partitions are usually at the start of a drive thus there isn't any 'left' to move them to.

You may want to edit the thread title to this effect.

Re: Can the left side of the Arch Linux EFI partition be moved?

There's no reason that it shouldn't work, at most you will have to reinstall/reconfigure GRUB (which is what your friend should've done on MBR and with which I have first hand experience) but afaik GPT and EFI systems are largely independent of the exact sector positions for purposes of operating system loading, so you are unlikely to even need to do that. In any case, you should make a backup, there's always something that could go wrong with deep changes to partitions like that (regardless of whether it is theoretically possible, which it is)
