I installed Xubuntu 18.04 on my 32 GB USB stick by choosing USB as a partition instead of the drives on my HDD. It took a long time to install (around 2 hours), but at the end it said that the installation was successful and to restart my PC.
Now after I restarted my PC, it wouldn't boot to my USB with Xubuntu on it.
When I view them from Windows, my USB drive appears as these two icons:
There are two of them because I used some space for swap area.
Is there anything i can do to make this bootable or should I reinstall? If I need to reinstall, is there anything I should do differently?
