How to install multiple OS on a Custom or Retail PC, (dual boot Windows 8 and 10 USB Installation).
Setting up a dual boot can be a risky task if you have no idea what to do. I hope this video helps or can help you, however, if you are stuck on anything at all just reply to this comment and I will help you out some more or you can just simple do some research.
Do bare in mind, one persons PC can be very different from another persons PC. so I tried my best to make this a general video. Overall the whole process should take you about 1 - 2 hours.
I FORGOT TO MENTION THIS IN VIDEO... PLEASE MAKE SURE YOUR RESET YOUR BIOS SETTINGS TO DEFAULT AFTER YOU'VE FINISHED!

WINDOWS & GPT (WHAT IT MEANS AND IF YOU HAVE GPT ERRORS):
Booting from GPT is only supported for 64 bit editions of Windows 7 (and Vista) on UEFI based systems.
If your computer does not support UEFI, delete all the hard drives partitions and create a new partition (backup any data first):
1. Boot from the Windows DVD
2. Click Install Now
3. At the setup screen, click Custom (Advanced)
4. Click Drive Options
5. Select the partition(s) you want to format
6. Click Format - this will delete EVERYTHING on that partition
7. Create a new partition and select a partition to install Windows on.
8. Continue with install.
GETTING GPT ERRORS?: "windows cannot be installed on this disk. The selected disk is of the GPT partition style.":
try the commands bellow in the windows setup section.
(N.B do this at your own risk!!):
>> press shift +f10
>> list disk
>> disk "number"
>> clean (exclude if you don't want to format the disk)
>> convert gpt
