I bought an Acer Travelmate with Vista installed and received a free upgrade to Windows 7. May laptop has a problem that requires a reinstall of windows however my update disk is scratched. Can I use any windows 7 home premium disk and my key or do I need to reinstall vista and obtain a new upgrade disk.
I think that it is more straightforward (although not easy) to do just a straightforward upgrade - it is complicated if you have to reinstall the upgrade for some reason and don't have access to the original version. I don't think Microsoft have explained things very clearly about their upgrades as lots of people are having varying degrees of difficulty.
I agree with you about the easy option would be to just have installed the new version of windows with the upgrade key - some marketing ploy perhaps because an upgrade is cheaper.
I am assuming everything is working ok now - if so could you please turn the grey tick to a green one so other readers who may be having the same problem may be able to more easily find a solution.
