I am using an HP Pavilion 20 All-In-One

I used a USB to install Ubuntu and went through the basic start-up options. I selected to finish installing Ubuntu while erasing everything else on my computer. After Ubuntu finished installing I was given a message saying that I needed to restart my computer for everything to go into effect. Now everytime I restart my computer it gets stuck on the HP logo and refuses to boot.

**Things I've Already Tried**
- Unplugged the computer and held down the power button for 15 seconds
- Ran a DPS Self-Test and received a completion code of 0
- Tried booting from the USB again

Any help would be greatly appreciated, I've tried nearly every solution I can find online.

Try to see if reseting the boot order works, if not try to see if it is setup in the correct mode of bios emulation (CSM) or efi booting. If it is confused on this the computer will not boot.
