How to dual-boot?

[Cayden]

So I've already installed windows 10 and had running it for months now. But few days ago I created a partition on the same drive and installed windows XP on it. Now i cant find the answer to boot back to windows 10 as I'm only booted to XP.
Is there a way for me to boot to windows 10 or is it impossible to do that now?

Good question and I do not know the answer .
In previous generations you always had to install the older OS first .

Now it may be possible to add a bootloader that can start either operating system . I would suggest you research that and see what you can find

Boot from Win10 installation media.
Go to Repair your computer/Command prompt
use bootrec command to fix bootloader.

• 
  bootrec /fixbmbr
  bootrec /fixboot
  bootrec /rebuildbcd

After that boot into windows 10 and use EasyBCD to add winxp boot option to bootloader.
