No user interface

[Hanniballec]

I have an HP Stream 8 5901 Tablet (model K4F55UA#ABA), that is/was running Windows 10.  OVER  A YEAR ago, I tried to performed an update... either a firmware or Windows (don't remember what...ugh), but the update required a user confirmation on reboot.   Unfortunately, the user interface drivers are apparently not yet loaded (touch screen or keyboard/mouse) and I have no ability to cancel or confirm the process.  I got frustrated and left this thing sit in my desk, and am now trying to resurrect it... HELP!!!  How do I move forward or backward (prefer to cancel)

If you can't see the picture, the message reads:

• A configuration change was requested to clear this computers TPM (Trusted Platform Module).  Warning:  Clearing erases information stored on the TPM.  You will lose all created keys and access to data encrypted by these keys.  Press YES to clear TPM.  Press NO to reject this change request and continue

Hi:

I wonder if you bought one of these, and plugged a USB keyboard into it, if you would be able to use the enter key/arrow key /Tab key to accept/not accept the change...

One of the reviewers uses this device for a standard USB KB, I read.

Thanks for that Paul.  I do have the micro to USB adapter and have tried all manner of mouse, keyboard and USB boot device without any luck.  It appears the USB port is not recognized yet.

Problem solved from [edit].  It turns out that ONLY the ESC and F12 key will work on a USB keyboard during boot... ESC for NO and F12 for YES.
