Hi, First post from me! I purchased a laptop a few months back just as Vista was launched, I did not want to use vista so I formatted the HD and installed XP. I then realised that the recovery disk was stored on a partition that I deleted!! I'm now ready to install Vista on my laptop and have a real copy(OEM) that I purchased from Ebuyer. The real copy has been installed on my desktop pc and I have used the licence code for that PC. Can I now use the same CD but use the Vista licence code that I have on the bottom of my acer laptop??? Will it work???
