How to change Windows boot manager priority

I recently had to reinstall Windows 10 on my PC due to some issues, the problem is whenever I start my computer I always have to press F11 to select what Windows boots from. I have 4 options to select from to boot Windows:

1. Windows Boot Manager (P1: [Drive Name])
2. Windows Boot Manager (P5: [Drive Name])
3. [Drive Name]
4. [Drive Name]

All of the drive names are identical (I do have 2 HDDs but only 1 has any data on it, multiple formats of the spare drive have made sure of that). Windows can only boot from boot option 2 but by default, it tries to boot using boot option 1. I have managed to swap options 3 and 4 with 1 and 2 but I would need to swap 2 and 1 so the computer boots correctly without having to select the correct boot option.

I have been through the BIOS and boot order settings and I haven't been able to find a way to swap boot option 1 and option 2 around because they are group together as 'Windows Boot Manager'.

How would I go about swapping them?

Solution 1:

Start > Run > msconfig

Go to the Boot tab. Choose a different drive, and click Set as default.
