    how to add dual boot to Windows 10


    new around here, so hello everyone ....

    Just got new desktop tower with Win 10 Pro on it. Added two old drives to it, one with XP pro, and one with Win 7.
    Wanted to have multi-boot option on it, like I had with the old machine, but Win 10 loads right away, w/o giving me option to choose.

    I did some digging around, found the info about UEFI firmware settings (listed @ How to Access the BIOS on a Windows 10 PC), and started to play with it, but got stock on Secure Booting, meaning the "UEFI Firmware Settings" window opens "zoomed in", and I can't see the options menu listed on the left side ...

    Open a command prompt (admin). Just click on the start icon, start typing the word command. Command Prompt should appear at the top of the list, right click on it, run as administrator.

    Let's say your Windows 7 partition shows up as F: drive in file explorer and your Windows XP shows up at G: drive. You would run the following commands:

    bcdboot F:\Windows /addlast /d
    bcdboot G:\Windows /addlast /d
    exit

    The paths in red are to the alternate Windows folders that you want to add to the boot menu change the drive letters to whatever they actually are on your system.
