Hi there I don't know what to do at this point so I figured I would ask you guys. So I'm fixing a friends pc it is a Acer E1-510 and the hard drive died in it. I know it is the hard drive 100% it sounds like it went thru a blender so obviously the recovery is gone and the HDD is toast my friend is going to buy a HDD and I'm going to replace but my question to you is actually its a 2 parter 1) there is no sticker on the pc and I contacted Acer and there no help. and question number 2) my friend doesn't know what version of Windows she had on her pc. From what I can gather online either 8,8.1 or 10 I'm thinking one of the first 2 because she knows it was updated a few months ago and looked different after that....I've been told that if I reformat with the right windows verison that it will recognize the key embedded in the bios I don't know if that's right and another question and last question is there a way on Microsoft's site do download the OS without having your key because well I don't have it
