    lean OS Install-Windows 7 Ultimate/Home OEM over Windows 8

    Tech forum noob here. Quick & possibly dumb question for you Windows 7 & 8 tech people out there.

    I have OEM discs for Windows 7 Home & Ultimate as well as corresponding product keys. I can't stand Windows 8 or 8.1 on my Lenovo any longer. I want to do a fresh Windows 7 install on my Windows 8 laptop. I'm adept at reinstalling Windows 7 operating systems on any Microsoft Windows machine (pre Windows 8).

    With OEM Windows 7 discs, I essentially wiped the 1-3 partitions clean and combined them to create 1 raw partition to install whichever Windows OS I happened to be installing on any particular MS Windows computer. I think I have like 8 partitions on my Windows 8.1 Lenovo.

    Before I get to the point of no return on this, can my Windows 7 OEM discs successfully delete 8 partitions to create 1 partition to install an older OS on a Windows 8.1 Lenovo? (I have valid product keys).

    Yes, you should have that option at the beginning of Win7 installation.

    Note: If you want to install Windows 7, you must disable Secure Boot, because it is not compatible with Windows 7. But if Windows 7 64-bit installation does not succeed in UEFI Boot Mode (if you have an OEM PC that came with Windows 8 preinstalled), try installing Windows 7 in Legacy BIOS Boot Mode, but then you will need to delete all partitions.


    First, try this:

How Windows 8 is performing in home/home office operation
Just My opinion.. Windows in the Win8 version is not suited for home use any longer. It is overly complex, and, even for experienced Windows users, it is counter intuitive in many areas. I think Windows 8 has taken complexity “one bridge too far” for ordinary users. This comment by me, a MSEE...
