Hello, i already prepared a usb drive with e2b, and some payloads in iso and imgn, i have two partitions for legacy and uefi boot, all going well. What i need now is a 3rd partition to make backups, so i can use a all in one pendrive, for live tools booting, backup, etc. i created a pendrive with 3 partitions, but every time i use switch e2b to boot imgn images, all the partitions are deleted. how can i do this maintaining the 3rd partition ???
