    Windows 8 Laptop Windows 7 Desktop

    Made a huge mistake!


    My aunt purchased a windows 8 laptop, hated windows 8 and asked me to put windows 7 on it.

    Having installed windows 8 on my laptop and then reverting to windows 7 and going back to windows 8, I thought that this would be easy.

    I had trouble booting to the windows 7 cd, so I ran it from the logged-in desktop. Then the stupid thing just wouldn't do anything at all, so I plugged it's hard drive into my windows 7 desktop and deleted all of the partitions (the big mistake). I thought surely now it will boot from the windows 7 CD. But all it does is say secure boot failed.

    I cannot for the life of me figure out how to get into this computer's BIOS settings to turn secure boot off and legacy boot on. I had no idea what either of these things were before I deleted windows 8 and couldn't do anything else with the computer.

    I tried a bootable MS DOS but it didn't work, and then when I tried it on my desktop I realized that I have no idea how to use MS DOS.

    The computer is a Sony Vaio SVE15126CXS

    I was a master at windows 7, but the new windows 8 sharades have got me all confused and stuck.


    Any help would be hugely appreciated!!!!!

    Welcome to EightForums

    1) Downgrade to Windows 7.
    Downgrade Windows 8 to Windows 7
    Warning you must have the uEFI/BIOS firmware setting in Step Three set.


    2) If Using a USB Pendrive on a PC with a uEFI BIOS.
    USB Pendrive need to be formated to FAT32 as in
    UEFI Bootable USB Flash Drive - Create in Windows
    Take note of Step 11 for Windows 7.
    Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

    Thank you, I already got drivers for it, I got them before I tried to re-install. I am tech-savvy enough to know to check for windows 7 drivers haha.
