Topic: Can't grow EFI partition on GParted Live USB

Originally the EFI partition was 100 MB. I was able to move 400MB unallocated space into the partition but I cannot actually resize/grow the partition. Can you please help?

256GB SSD:

/dev/sda1 fat32 /boot/efi flags: boot
/dev/sda2 ext4 linux mint
/dev/sda4 ext4 xubuntu

Thanks!

Copying the log below:

Re: Can't grow EFI partition on GParted Live USB

Unfortunately the libparted library which performs the resize operation for FAT32 file systems does not work with file systems less than 256 MB.  See the following bug:

Bug 649324 - failure to move / resize fat32 partitions less than 256 MB in size

As a work around you might consider backing up all the data in the partition, re-format to ext2, resize the ext2 partition to the correct size, re-format back to fat32, then restore your data.
