    Dual booting Windows 10 with 8.1


    Hi I have installed Windows 8.1 on a separate drive. Windows 10 (20h2) already installed on my Dell desktop. 8.1 was installed independent of 10 (drive disconnected) so the boot loader choices was not picked up
    I have two questions :
    1. Do or should I disable fast boot and secure boot in Bios?
    2. I am using easy bcd to set up the dual boot option screen. Which bootloader should I use as default 10 or 8
    1?
    Any and all advise appreciated

    :)

    Dual Booting with Windows 8.1


    The procedure below will allow you to boot Windows separately or in dual boot configuration.
    Here's what I recommend to do:
    1. Disconnect the drive containing Windows 8.1
    2. Install Windows 10 with one drive connected.
    3. After step 2, reconnect the drive containing Windows 8.1
    4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
      NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
    5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
    6. Reboot the PC. You should have a dual boot screen.

    NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

    Dual booting Windows 10 with 8.1

    windows 10 slow boot

    I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

    I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

    In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.
