Cannot dual boot or boot from usb/dvd.

Hi Bill,

Thank you for posting in Microsoft Community.

I understand your concern and frustration you have been through. I will be glad to assist you.

1. Have you changed the boot priority to USB/DVD?

First you need to verify and if necessary change the boot order in the BIOS settings so that your PC will boot from the DVD drive (or USB device if you created a bootable USB Flash drive). You can do this by making the DVD drive / USB device the first device
listed in the boot order and the hard (or SSD) drive your second device the BIOS, exit as save the BIOS changes.

I suggest you to follow the link suggested by J W Stuart on January 23, 2015.

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.
