  1. I tried to install Windows 7 Profesional I have now ruined my computer


    I tried to install Windows 7 Professional I have now ruined my computer. I formatted the hard drive now nothing works. Won't even let me install Windows 10. What code do I need to take my computer back. I can't remember what you call it! It's an HP pavilion and a phone number for them would be most helpful. It's saying I can't install it on the 1 TB hard Drive. And I need to have it repaired. What a bummer. I am beginning to hate Windows now. Just seems to be headache all the time with them. Thank you in advance.

    :)

    HI I have 22 hp prodesk 400 g4 sff from hp for my corporation with windows 10 profesional 64 bit oem license, I want to deploy all this pc to windows 7 profesional 64 bit oem license as all my organitation has all de computers in windows 7 64 profesional
    and I want to keep it in that situacion for diferent reasons like homogenius profiles, the question is that I do not know what is the process to downgrade these 22 pc's into windows 7 profesional 64 bit oem license, I know that hp has given me the posibility
    of downgrading rights as I can see that rigth in all the cases of the pc's sent to my organitation.

    On another hand I do not have any license key, my doubts are:

    Do I need a windows 7 profesional 64 bit oem license from hp?

    who can give me the windows 7 profesional 64 bit oem license?

    where is the oem license , is in bios?, is involved in this process any kind of certificate or commands to do it?

    is this posible to do it just with a windows 7 64 bit iso and how do I set the oem license in each windows 7?

    I have so many question to do this process that I need some help.

    thanks in advance.

    EDIT :
    FWIW on a clean install even on a drive with another OS or prior Windows install Windows set up can usually format and partition the drive correctly for you .. ( see the next post below )

    If you delete all partitions where everything shows unallocated, it should install fine. You can do that in advanced options when you get to 'Where do you want to install Windows'. Just have the hard drive you want to install Windows on the only hard drive connected during the install.
