bobbyflay397 Posted May 22, 2010 Report Share Posted May 22, 2010 When I bought this laptop, the gateway nv 5214u or something, it had windows vista premium. I then ordered a free windows 7 home premium(full version I'm presuming since it wasn't downloaded from the internet and it was sent by microsoft and it was part of a deal where after january you get one for free)and I installed it. When my computer started slowing down, my friend offered me to upgrade to windows 7 ultimate because I reinstalled the windows 7 premium and it didn't have internet. Now that I realized it wastes two times more resources than the previous version, I want to change it back. I tried using the same disc I used to upgrade from vista - windows 7 but finally figured out that its suppose to be windows vista premium to windows 7 premium. Can anyone help me on how to turn it back to the previous version?(I used the regedit method and many more) Quote Link to comment Share on other sites More sharing options...
ɹəuəllıʍ ʇɐb Posted May 24, 2010 Report Share Posted May 24, 2010 Did you install all these various Windows 7 version in the same partition (on top of each other), or each in a separate partition? Quote Link to comment Share on other sites More sharing options...
bobbyflay397 Posted May 24, 2010 Author Report Share Posted May 24, 2010 Did you install all these various Windows 7 version in the same partition (on top of each other), or each in a separate partition?I believe in the same partition, because I only had one version each time and I still have one version on this laptop right now.

ɹəuəllıʍ ʇɐb Posted May 24, 2010 Report Share Posted May 24, 2010 In my view it would be the best to format that partition, then install the Windows version of your choice. Quote Link to comment Share on other sites More sharing options...
bobbyflay397 Posted May 24, 2010 Author Report Share Posted May 24, 2010 yeah... but anyone have an idea on how to install windows 7 home premium on the disc that I used to install it when I had windows vista? Quote Link to comment Share on other sites More sharing options...
Boris Posted May 25, 2010 Report Share Posted May 25, 2010 Yes - exactly as Pat stated above :-......... format that partition, then install the Windows version of your choice. i.e. Win 7 HP Quote Link to comment Share on other sites More sharing options...
bobbyflay397 Posted May 26, 2010 Author Report Share Posted May 26, 2010 How can I format it? It doesn't let me format the local disk c because the windows folder is in there. It also doesn't let me move it or alter it.(I'm administrator of this computer) Quote Link to comment Share on other sites More sharing options...
Boris Posted May 26, 2010 Report Share Posted May 26, 2010 You cannot format your current (working) partition from within Windows, you need to boot from your Win 7 HP disk.Read this - re. doing a custom installation of Win 7 :-http://www.pcmag.com/article2/0,2817,2354696,00.asp.
