I need to install Ubuntu on my USB pendrive 3.0 in order to have my "portable computer" everywhere i go. BUT i need it to work also on EFI systems. I've tryied by installing ubuntu on a VirtualBox hd (the copy of the USB pendrive) and it works if i set the VM as EFI. The problem is that it doesn't boot on other computers. I've done a manual partition with this scheme:
32GB USB pendrive:
- 150 MB: efi partition (EFI BOOT) - 258 MB: ext2 partition (BOOT) - the rest: ext4 partition (root)
Any ideas why the bios recognize all the partitions but when i try to boot from the efi one nothing happens? If anyone can suggest me a guide or something useful for what i'm doing it will be very kind...
Thanks in advance for the answer
