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. – 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). 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 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
