Not sure if it’s just my end but from what I’m seeing this link does not work. (if it is working for other please let us know!)
you should be able to install windows from scratch (will have to look at other forums as you’ll have to get into bios to be able to boot from an external device.)
without having to flash the TD image, as flashing at the moment may actually be a more tedious task due to the lack of TL image as far as I am aware.
spam F8 before windows boot, you should get to the boot menu, from there choose “last known working configuration” and see if that solves the problem for you
