so I have installed ElementaryOS (that is based on ubuntu) on my 16GB flash drive. Everything worked just fine on my main laptop, until I had to use it on another one and it doesnxe2x80x99t boot up. When I select the Flash Drive as the boot device, it simply shows up an empty screen with a blinking cursor (my flash drivexe2x80x99s xe2x80x9cin usexe2x80x9d light blinks synchronous to the cursor on the screen). I have Safe boot disabled, CSM enabled, and it boots up on Legacy. I have tried all of the ports as well as my second Linux USB drive, nothing has changed.
My laptop is an old 2012 Asus with an i3 processor and 4GB of ram. It has Windows 10 installed on the internal SSD and it runs just fine.
I have seen people with a similar problem, but no fix worked for me.
