Accidentally booted ASUS laptop from Surface Hub 2S Recovery USB, now can't boot/reinstall Windows

Thank you, Cezar!

I had actually followed that article closely in the hopes I could get out of my situation that way. Unfortunately I could only make it about 90% through the process because the final step involves booting into the Surface UEFI and installing the management file on a special screen available there for that purpose. I had created a management file with my own self-signed certificate per the instructions, but since my UEFI is ASUS and not Surface, I have no screen/section available where I can put the new management file. If there's anything I'm missing with this, I would be happy to check anything else. I don't know if it is possible to install the new device management file some other way, perhaps through Linux or something, but I can't do it via the normal Microsoft directions, unfortunately, since my situation is so different.

I had considered opening a support case and would love to do so, but I'm not sure how to do it since this is a personal laptop and not for an actual Surface device. Do you think Microsoft will let me open a support case as just a normal consumer about this issue? If so, do you perhaps have a link to where the best place to enter that support ticket might be? 

Thank you so much for reading my post and offering help and suggestions.
