I have a boot able USB disc and I can start installation on my computer but Windows stops at Rapid storage technology Override with the order to "stop installation and restart", not an error message.
Computer: HP Envy 64 desktop model TEGY1-0250X1
OS: Windows 10 1909 home Version 10.0.18363 Build 18363
Also. Ubuntu does not ask what type installation i want. I want to remove windows.
If Ubuntu will take charge of my computer and install I will pay a reasonable amount. I am 77 years-old and doing this is difficult.
