So my iMac is away for repairs and im stuck with my old laptop witch runs XP. I have a computer in the house that is brand new runs windows 7 and has obviously come with the install disc's. Would i be able to put that windows 7 disc in this and install it successfully? One thing i am worried about though, if i do do this, will my dad still be able to use the disc if he ever wants to reinstall windows 7 on his computer? Cheers.
