So my windows 10 < C: Drive > is all in tact except it won't boot up .. I do have on the partitioned drive < D: windows XP>.. so D: boots up and C: does not boot up ..

so I am currently looking to find an ISO download to fix my windows 10 which I upgraded from window 8 retail disc back in 2015 .. and have been using windows 10 ever since and unfortunately do not have the USB ISO created back then ..

so I see lts of google site to do this ,, but they appear to be complicated and hard to find to download the free from microsoft ..

any one know a direct link to do thsi and maybe offer some advice on why or how to fix my un boot-able windows 10 ??

thanks

Terry
