hello ,
i am trying to install W10 on a machine that has a legit copy of W8.1 in place .
i have tried three methods :
windows media creator
iso usb installer
the windows "mount-n-boot" installer
in each case the machine chokes on the first reboot and reverts to 8.1
there is an error message :
0xc1900101-0x30017
and it mentions "first phase boot failure" (or similar wording)
also mentioned was an expired security exe .
i did not see a specific thread for this model of comp .
some recon/google-fu shows that there are a lot of people having issues installing W10 .
any help will be most appreciated .
