Welcome to the HP Forums 🙂
I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand you are unable to boot from USB on windows 10 64 bit for HP x2 detachable PC- model 10-p020ca,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Did you check the different types of recovery done on HP Products?
Installing Android could have deleted the partition to revert back to windows, do you have HP recovery media kit on the USB drive?
While you respond to that, here's what you need to know:
If you don't have a recovery media kit, please order one using this link: Click here
