Hi, I have recently tried to get a factory reset on my Aspire 5742G and after introducing the SN or SNID in the eRecovery webpage, I got error. The reason why I want a factory reset is because the laptop was delivered to me with an un-genuine windows(7Ultimate 64bit) and I want the genuine windows(7Home Premium 64bit) to be able to upgrade to windows 10 later on without problems. Otherwise the laptop works great and I had no problems with it but this is my only concern, the un original windows OS. Also I should mention the laptop doesn't have the Win 7 sticker anywhere on it and I don't have the original packaging. Any ideas how I can fix this?
