    Dual Boot Windows 7 & 10

    Dual boot XP on an existing Windows 10 installation.


    I have a Toshiba Satellite S875-S7136 laptop. I already have Win10 x64 installed on the disk's primary main partition and the remaining half of the disk is unallocated space. In the BIOS, I set the bios to look for the DVD drive before loading the hard disk.

    I first tried to run setup from the disk while Windows 10 was running. However, the install/setup option is greyed out and non-functional. I then tried rebooting the laptop to the DVD drive, but it skips past the DVD and runs from the hard drive instead. Any way I can get past this impasse?

    Looks like CD/DVD inserted is not bootable.

    Have you turned off Fast Startup in Windows 10?
    Turn On or Off Fast Startup in Windows 10

    If Fast Startup is on, then when you 'Shut Down' Windows 10, it actually does a form of Hibernation, which I think means the BIOS doesn't let another OS boot.

    That's a good point, but a restart (reboot) is not affected by Fast Startup. I would turn it off, in any case.

    Also, check your BIOS setting for boot sequence once more. I know you said you set it, but if you accidentally exited with a save of the settings, it did not take. Just check it one more time to be sure.

    Also a question. This DVD.....is it an OEM XP Install Media? If it is and it did not come with your current machine (i.e. matches the key in the MB), it will not work. OEM Install media will not work on different machines.

    Has your pc got secure boot as that would stop it. You always install the oldest o/s first as it wont understand the boot for new o/s so if you install xp after 10 things wont boot you will have problems. Why not run it from a virtual pc with virtualbox which is free Downloads – Oracle VM VirtualBox

    Another good point. I had the same issue when I tried to put Win 7 on after 10. It got all messed up in the BCD. Still, if that's an OEM XP media, he's gonna have problems with the license.
    @idigweeds , do you have any other bootable DVD, like a Windows Rescue or anything you could try to see if your BIOS is set right and will boot from any DVD?

    May have been bootable once upon a time but CDs are not most reliable media.
