The boot drive is actually the drive containing the operating system, it is also called the system drive. The computer needs to be booted through BIOS/UEFI to start. BIOS/UEFI is a program that is solidified on the ROM chip of the computer motherboard. It stores the most important basic input and output programs of the computer, the self-check program after power-on, and the system self-start program.
Usually, we use HDD to store the operating system. At this time, the HDD is the boot drive. But some users may replace the HDD with SSD due to better performance. After replacing the SSD, you have to set the SSD as boot drive. Because every time the computer starts, the BIOS/UEFI loads first, and they tell the computer which drive it should use to start Windows. If you are booting from a new drive, you should change the boot order of new drive to the first.
