I am currently dual-booting Windows 10 and a different Linux distro, which I want to replace with Neon. My plan is to format my /
partition but keep my /home
partition, which is separate.
I use the latest Neon ISO, currently neon-user-20250123-1319.iso
, written into a USB stick.
During installation, I select “manual partitioning” as I’ve done in the past. I select the following in it:
- My EFI partition mounted at
/boot/efi
, NOT formatted - My root partition mounted at
/
, YES formatted - My home partition mounted at
/home
, NOT formatted - A couple of other partitions mounted at
/mnt/
subdirectiories, NOT formatted.
When I click “next”, I get a popup window warning me that I have not selected an EFI partition, and I should go back and select one. However there was no special field in the manual partitioning screen to select one.
I also noticed this popup says the partition should be at least 300 MiB. My EFI partition is 99 MiB. Is this why the popup appears?
I tried to use KDE Partition Manager to enlarge it, but even after I tell it to shrink the partition after (which is the Windows one), enlarging the EFI partition is not an option.
So, two questions:
- Is the size of the partition the reason why that popup appears? If not, how do I “properly” select an EFI partition?
- If I need to resize it, how can I do it without losing data?
