My ultimate aim is the following: - A portable installation of ubuntu 16.04 LTS that will run on BIOS and EFI and UEFI machines - An encrypted disk (not just home folder)
I have the following machines: - Mid 2015 Macbook Pro - 2007 PC - BIOS motherboard, core2 quad processor, 8GB DDR2 RAM - running windows 10
So far I have installed ubuntu 16.04 LTS on a 64GB usb key with the following partitions: - 300MB EFI partition - 300MB Boot Partition (ext2) - 63.4GB (or whatever) encrypted partition (ext4) - boot loader installed to the USB device (not a partition)
this configuration allows the USB to boot on the macbook pro, but on the windows machine I get the following:
error: unknown filesystem
I saw on this page (https://help.ubuntu.com/community/Installation/FromUSBStick#Multiboot_pendrives) that a "multiboot pendrive" is discussed, however this page (https://help.ubuntu.com/community/Installation/UEFI-and-BIOS) suggests that it is unstable.
Is it possible to install ubuntu 16.04 LTS on a USB such that it is encrypted, and that it can boot on EFI and BIOS machines?
Edit: all computers are 64bit
