I installed aomei and it won’t boot up [closed]

I installed aomei backupper to my hp desk computer using an external drive. When it restarted it won’t boot up. I’ve tried changing the boot order but it won’t boot. How do I get it to boot? Also I get a message before it says that it won’t boot. It reads checking media presence…
