LMDE 3 Live Installer Partitioning Errors

[kylebaker]

I'm fairly new to Linux but I know how to poke around pretty well.

My issue is in the LMDE 3 Live Installer when it gets to the Partitioning page.

When I select a partition in the list and set the Mount Point, it doesn't "stick" when I hit OK. If I type out the Mount Point (ie /boot/efi) and hit OK, it sticks. However, when I set all of the partitions to what they should be and hit 'Forward', I get an error that states "The EFI Partition is not bootable. Please edit the partition flags."

My drive is a 256Gb nvme drive. These are the commands in terminal I did (based on this site:https://www.addictivetips.com/ubuntu-li ... ine-linux/) to try and fix the issue:

'sudo parted /dev/nvme0n1'
'mklabel gpt'
'Yes'
'mkpart ESP fat32 1MiB 550MiB'
'mkpart primary linux-swap 550MiB 21030MiB'
'mkpart primary ext4 21030MiB 50GiB'
'mkpart primary ext4 50GiB 100%'
'quit'
'sudo mkfs.vfat -F32 /dev/nvme0n1p1'
'sudo mkfs.ext4 /dev/nvme0n1p3'
'sudo mkfs.ext4 /dev/nvme0n1p4'

From here I tried the installer again and tried the manual input of the Mount Points but still came with the same issue.

My goal is to have 4 partitions:
Partition 1: EFI
Partition 2: swap
Partition 3: /
Partition 4: /home

What am I doing wrong? Thanks in advance.

"The EFI Partition is not bootable. Please edit the partition flags."

In the installer's partitioning page, mark the EFI partition > Edit > set the flags: boot, esp > Ok
Hope this helps!
