If this HTPC is previous generation processor/chipset, the image isn't likely to work anyway. You are better off installing Windows and tools from scratch...
thanks for your response Scott but as a principal i dont opt for reinstalling unless its really unavoidable but in this case i overcame over 90% of the issue and if you didnt notice in my somewhat long overview of the process i got the image to finally load am just stuck at adding usb3 driver that will actually load by he loginscreen phase or find a solution to force autologin from reovery or advanced boot options. one way or another i am sure its resolvable and i aint close to giving up and reinstalling.
well Scott, i love the taste ove success especially when i hear someone saying it cant be done!!!!
to summ it up like i figured as neither network nor usb were working i had to find a solution that could be done offline. i enable autologin from the recovery console by loading the software registry hive and adding proper autologin configuration keys. once that was done i created a batch file that basically runs the usb3 installation unattended. once this was done i had o push the installation to the machine as well as put the batch in the statup.
needless to say that now everything is working and i successfuly migrated my 10 years old machine to the new nuc fully working.
many thanks to.. well me and i hope this helps someone out.
p.s thanks scott for saying it aint likely to work anyway..
cheers and good night.
