How To Create A UEFI Bootable Ubuntu USB Drive Using Windows
Lead discussions. Quick Links Explore popular categories. You will need them both! Nowadays, in the interest of security, performance and backwards compatibility, there are many semi-hidden options and features which can get in your way. Given enough experience and patience you can work around them. Below is a selection of problems that got me moderately stumped along the way.
I have only tested these instructions with Secure Boot turned off. Even though Ubuntu does support Secure Boot it comes with signed bootloaders I have no idea if my method uses the signed bootloaders or not.
I suggest turning off Secure Boot if possible. I had to disable both. This feature takes some shortcuts when it comes to booting and also makes the NTFS filesystem remain in a dirty state, making it unwriteable from Linux. However, your root filesystem is inside a device attached to this USB controller. Therefore the controller resetting means that Linux can no longer communicate with the USB-attached hard drive.
Therefore the Linux boot will hang forever without any further indication as to what went wrong. If you are only using modern operating systems with USB 3 support anything newer than and including Windows 8. Install Ubuntu Linux regularly. When it prompts you about the disk layout choose Something Else and partition your external HDD the way you want.
Caveat: I chose to use btrfs which — as I learned along the way — makes things a bit more complicated down the line. This guide assumes the use of btrfs and will point out the caveats with this approach. Unfortunately the Ubuntu Installer assumes that you want a dual booting configuration alongside Windows. This causes two problems. For starters, the external HDD is not portable as you cannot boot with it on another computer.
We have to fix that. We have to create one on your hard drive. Why not just click on GParted on your desktop? Of course it is, I am using it to run the computer off it, duh! Resize the first partition on disk to have another Mb of free space after it. Create a new partition on the free space, changing the file system to fat Apply operations. You need to do that now for the next step to be possible.
Right click the new partition. Click on Manage Flags. Set the boot and esp flags. One more thing! Note down the the partition that contains the ESP filesystem.

The process is different depending on the format of your root partition on the external hard disk. If you DID use btrfs, you made your life complicated. We need to mount the btrfs subvolume containing the root partition instead of the entire partition.
The rest of the instructions are common, no matter if used btrfs, ext4 or something else. Right now our external drive has an empty ESP. We need to put a bootloader in it to make it actually, well, bootable. First caveat: all the instructions you find on-line assume you are using a dual boot system with Windows or macOS. When you have an external drive it is critical that you use the —removable option in the last step.
Normally this not supposed to be used for permanently installed Operating Systems. Second caveat: installing the bootloader is only possible from inside the Linux installation we want to boot. However, we need the bootloader to boot that installation, leading to a Catch issue.

The solution is to run the bootloader installation through a chroot jail. The error is misleading! The actual problem, as I understand it, is that there is a discrepancy between the mounted device and the path to the chroot root.
