Cannot Reformat HP Stream 11 Laptop

[Ngand]

Description of problem
Cannot Reformat stream 11 PC. The laptop was purchased from a school with it being locked. F11 cannot be used.
Cause/Steps to recreate the issue
So I created an ISO Imaged thumb drive (To act as DVD) this allowed me to try and reformat the laptop to Win 10, Issue is i tried to reformat in that menu and it told me that the drive couldnt be formatted(so i gave up turned off the pc and went to sleep). I then wake up turn it on and my HP stream says no boot device found

What I’ve tried so far to resolve the issue
I have tried making a Nuke an boot iso image to see if it would read that, I tried just using the regular windows creation tool on usb to see if it would read it, I tried turning legacy support on, i have tried reorganizing boot order, i have tried opening the PC disconnecting the battery and letting the PC discharge and then letting the CMOS reboot still does nothing. Please help

We have no way of telling that you own the system legally or not. You will have to contact them or take the system to a service center so you can validate ownership.
