After having trouble with my Ubuntu installation on a USB drive (I found out that I had to create EFI System Partition), I can't launch Ubuntu. I read that Safe Boot Mode might be the issue, but it is turned off. The second USB drive broke down while trying to install Ubuntu on it, so I can't try out a different device.

Here's what it looks like.

  • Are you sure that your second USB drive broke down? Maybe there is 'only confusion' due to some written data, and it might be possible to restore it to a standard storage device. See [this link](https://askubuntu.com/questions/144852/cant-format-my-usb-drive-i-have-already-tried-with-mkdosfs-and-gparted/933035#933035). – sudodus Feb 06 '19 at 15:37
  • What system do you want on your USB drive? 1. A **live-only** or 2. a **persistent live** or 3. an **installed** system (installed like into an internal drive)? The advice will depend on what kind of system you want. – sudodus Feb 06 '19 at 15:42
  • I want an installed system – majster_klepka Feb 06 '19 at 16:51
  • I suggest that you try according to the following link: [How do I install Ubuntu to a USB key? (without using Startup Disk Creator)](https://askubuntu.com/questions/16988/how-do-i-install-ubuntu-to-a-usb-key-without-using-startup-disk-creator/942312#942312). It helps if you can unplug, disconnect or via software settings disable the internal drive (particularly if you want to install in UEFI mode). – sudodus Feb 06 '19 at 17:57
  • @majster_klepka Could you please check the contents of */etc/fstab* on USB flash - for what partition this UUID is used? Please add this info to the question. Also add output of `sudo lsblk -f` with inserted USB flash y – N0rbert Feb 06 '19 at 18:45
  • @N0rbert /etc/fstab was empty and I didn't get any output of the command you suggested. However, I installed Ubuntu according to the link from sudodus and it works! Thank you. I have another question: Can I manage remaining space and create a partition to be used as a regular flash storage? After installation I have 49 GB of free space. I am going to use Ubuntu to learn web development so leaving 19 GB for it and 30 GB for storage would be great. – majster_klepka Feb 07 '19 at 13:56
  • @majster_klepka for compatibility with MS Windows ordinary data storage partition should be the first partition. This will prevent accidental formating of it in Windows. But you having data partition is a good idea, anyway :) – N0rbert Feb 07 '19 at 14:34

Well, I should have mentioned at the beginning that I want to have a second partition for storage. I used the LiveCD to unmount the USB drive with Ubuntu installed on it (with the method from sudodus) and allocate some space for storage. However, after creating second partition I could no longer run Ubuntu. I tried installing it once again, this time making the storage partition the first one. I chose FAT32 and set mount point to /windows. Then I allocated remaining space for Ubuntu, chose ext4 file system, set the mount point to /, and chose the USB drive (not Ubuntu partition) as the device for bootloader instalation. However, it still doesn't work. Here's the error message I get when trying to run it. https://i.stack.imgur.com/QL0RA.jpg
