Hi there and welcome
Can you please remove the power cable to the Asus then hold the power button down for 60 seconds then release.
Then connect the power cable, and try to power it on
Let me know if it now starts correctly please.
Can you return here to your question please?
ok, can you power it off.
Then hold down ALT and with it held down, power it on and keep tapping F9 until you get to the recovery manager
Are you able to get to this?
Please let me know.
