In checking to see if I could find any help for your problem, I came across this..... http://community.insigniaproducts.c...-bootloop-after-windows-10-upgrade/td-p/80567
Looks like you may need an OTG cable, through which you would attach a USB hub, and then a keyboard (to get into the BIOS for the boot menu) along with a USB thumbdrive containing the installation media to that hub.
Looks like a usb mouse might also come in handy.
