I brought the HP Clereon from JB with windows 8.1 installed on it , had troubles with iTunes . Was cut of half way through on a Friday afternoon . Not gonna drag it out but have put a new motherboard on because the one well ....anyway put the hard drive on new mother board but wanted an activation key ....after a few weeks thought well got 8.1 go and buy pro from JB and just upgrade the 8.1 . Didn't work and was told I wasn't allowed to do this . Ok so now again I've gone back to JB HI and have brought 8.1 , spoke to them and yep just put disk in and all will be good , I've just feel like after two copy's 8,1 , an 8.1 recovery disk , recovery usb and a copy of not really needed pro , can't put my windows 7 and what ever else back on . I'm actually feeling like my photo and so over it . I'm not blaming anybody because I'm at fault as well , but I've tried to do the right thing to fix and am out of pocket . Just need a little bit of help or advice .
