I have a desktop pc and I need to install linux urgently, I boot it fine without problems but an error appears when I run the pendrive, I already tried with ubuntu, kutunbu, ubutntu mate
this is my pc i5-9400F asus prime h310 r2.0 gpu gtx 1650 16gb ram
The message on the screen is clear, it says that it did not find any Operating System, it is likely that the OS was not copied to the pendrive correctly.
I use the Rufus program to create my bootable pendrive with Ubuntu and I never had any problems.
It is also likely that the pendrive has read/write problems. It would be good to also try other pendrives and see if the problem persists.
