I have installed Ubuntu on my USB drive. Currently, it holds 4 partitions:
- /dev/sda1 - fat32 mounted on /boot/efi
- /dev/sda2 - swap
- /dev/sda3 - ext4 mounted on /
- /dev/sda4 - ntsf for working with windows
I want the first 3 partitions (EFI, swap, and ext4) to be hidden from any Windows pc because it asks users to format them, which will break the installation.
How can I achieve that?
