    OP would have to either select which drive to hard drive to boot from in bios (if it allows that), or run msconfig to select it.

    Alternatively, OP could try and rebuild dual boot sectors, but with XP and 10 having very different bootloaders, I am not sure if this is a good idea.
    Computer has only Windows XP HDD installed. User adds the SSD on the next available SATA port and boots from Windows 10 USB to install to it. The bios is still probably set to boot from the HDD and Windows 10 will recognize that and update the boot files contained on the HDD rather then create new boot files on the SSD. Hence the advice to only have the SSD connected during install of Windows 10. After the Windows 10 install and after the XP HDD is reconnected if the bios goes back to booting from the Windows XP HDD, the user will know it because they will boot in to Windows XP with no choice to pick Windows 10 because the boot files on the Windows XP HDD will never have gotten updated.

    True but on some pcs, the bios does not always allow you to select which physical drive to boot from.

    On my Sony Vaio, I can only choose hard drive, and I have to select the drive I want to boot from via msconfig.

    Easy enough from windows 7/8/10 pcs but I cannot honestly remember far enough back if that would work on XP (I assume so).

    That was the only point I was really trying to make.

    Yup Done in my computer already. 4 partition with xp, 10, data, hackintosh.
    0. goto bios set legacy mode, boot non uefi per install with usb/disc
    1. Install xp first in first partition while creating win10 partition in second, and others max total 4 partition as primary. We use mbr method.
    2.install via usb or disc win10 or win7/8first if you upgraded win10 ticket.
    3. Pick manually install to second partition.
    4. Use easybcd manual to put the xp loader.
    5. Copy Ntldr from xp to win10, and win10 bootldr to winxp

    That's it.

    Just one point, starting with Vista, Microsoft Operating Systems do not have to be installed on a primary partition, just the Boot files, so it is possible to install more than four OS's on a single drive, as long as they are controlled from a system partition on a primary partition :) probably not of use to most but I have found it handy at times during Pre Beta and Beta testing

    There could be another problem considering SSD and Windows XP. For SSD it's best to run on SATA port in AHCI mode for which XP is very difficult to set because of lack of built in drivers. If it was installed in IDE mode, it wouldn't even boot,
    Unless XP ends up on another SATA controller that runs in IDE mode it's impractical to use in such a combination.
