You can select default boot drive using 'msconfig' (push Win key and type: msconfig).

Its only showing my default boot drive. Its not showing my other drive. It is also running Wndows 10. It is also Labled"C"when Im in that drive but it Its labled "G" when i view it from the other system. Could that be the issue?

I thought of this causing some kind of conflict but changing the main drives path from"c" to anything else i was told was going to cause problems.

If you have installed Windows on first disk, disconnected that disk and install Windows to second disk then it's not build boot menu to select which windows to boot. If that's the case then that boot menu must build.

Easiest its done with EasyBCD:

- Set your main disk to boot disk on bios

- Boot to Windows

- Install EasyBCD

- Open "Edit Boot Menu" (Only one is shown)

- Open Add New entry

- Select G:\ (Another Windows disk)

- Click "Add Entry"

- Open "Edit Boot Menu" (Two entries shoud be seen)

- Rename those entries, check "Use Metro bootloader", set time to wait boot selection

- Save settings, close EasyBCD

- Check with 'msconfig'
- Restart, on first boot you may see some short disk check, let it run.

When everything is working you can uninstall EasyBCD if you wish.

Here is screenshots how I did this with two separate test disks on my test environment:

(See disk configuration screenshot end of this posting.)

Running Windows set always used boot drive as drive C: and then add next letters to another disks.

If you don't want to see another Windows disk when another one is running then right click start button and open Disk Management. Right click that disk you want to hide, select "Change Drive letter-...." and  then select Remove.

Don't mind warning at this step. Now running Windows see only its own disk.

When dual boot is in use it's better to disable "Fast Startup".

- Open Control panel / power options

- On left click "Choose what the power button do"

- Click "Change settings that are currently unavailable"

- Un-check "Turn on fast statup"
