if you can get win 8.1 for $30 bucks do it. I loved it when I got win7 pro and office pro for like $60 total back in 08 -09 thru academic pricing.
Get it and you will be fine (if you cant retrieve your old key from bios). I just installed 8.1 to my new air ii and also did the upgrade to win 10.
My plan was to install win7 home because I had one laying around unused, then do the upgrade to win 10.
I didn’t realise that 64bit didn’t work. So then I tried to buy a key online….didn’t work…..so then I just went out and bought a retail copy.
I only bought the android version because I was going to save money but now I have spent $130 extra for an OS I didn’t think I was going to have to buy.
I could of actually got it cheaper if I ordered from one of the authorized resellers and waited a few weeks for it.
Not to mention I didn’t realize the x98 pro came out, so I could of just bought one of those win windows already.
I had to go through such a hassle to flash my air ii (HG5N), if I could do over I would of just spent the extra $50 and got a dual boot version…..lol I would have saved money hahaha LOL
