I'm trying to install Ubuntu in a separate hard drive from windows 10.
I have 50 Gb free space, I can create successfully the root, home, swap partitions but when I try to create the EFI system partition (in order to place here the bootloader) I get a ubi-partman code 141 error.
I have disabled secure boot and fast boot.Any help would be appreciated.
