How exactly do I do that? I'm new to this kind of installation.
In your BIOS there should be a boot options menu or something along those lines; in that menu you can set the order in which the BIOS checks your drives for bootable installations. If the Windows drive has a higher priority, the BIOS will check that first and boot Windows without ever checking if the other drive has something on it.
Alternatively you can bring up your boot menu, on most motherboard that's done by pressing f12, del or another f key - you can find out exactly what key that is for you by reading your motherboard's manual or looking it up on the internet. The boot menu will let you select the drive you want to boot from.
by the way, quote or mention me if you want me to see your answers - I saw this by chance because I still had the page open
