What Is a Boot Drive

A boot drive is a hardware device that contains the operating system for booting a computer. It could be a hard drive, floppy disk drive, CD-ROM drive, DVD drive, and USB flash drive.

A hard drive is the most commonly used boot drive. When you buy a new computer, an operating system is pre-installed on the hard drive and you can boot it directly.

As long as a computer has been used, users usually need to change boot drive. In other words, they want to replace the system disk with another one, and they often do it due to one of the following reasons:

They want to move boot drive to a new SSD for better performance.

Their old boot drive is

running out of space

and they need a larger one.

There are signs of hard drive failure and they plan to replace their boot drive before it damages.

It might be a little difficult for most common users to change boot drives by themselves, especially for the first time. If you are one of them, don’t worry. There is a detailed tutorial on how to change boot drive in the following contents.

Stage 2:Migrate OS or Clean Install Windows 10

After backing up data, you can change the boot drive without any worries. As mentioned, a boot drive needs to contain files required for a computer to start. If you want to boot from another hard drive, you need to install an operating system on the drive at first.

You have two options now: the first is to migrate OS from your old boot drive to the new hard drive with a third-party program; the second is to clean install Windows 10 on the new hard drive.

Option 1: Migrate OS to SSD/HD via MiniTool Partition Wizard

MiniTool Partition Wizard is a professional and reliable disk partition management tool. It can help you a lot in your daily life. For example, you can use it to resize partition, recover lost partition or data, check for hard drive errors, and clone disk.

This might not be the best option when the operating system on your old hard drive is corrupted, as you could also encounter problems even after changing the boot drive.

Now, let’s see how to use MiniTool Partition Wizard.

Step 1

: Connect your new hard drive to your computer.

a second hard drive

. Otherwise, you would need a USB adapter to connect the new hard drive to your computer.

. Then click


to start the data migration process.

The process would take some time, and you should wait patiently. Don’t shut down your computer during the process. When the data migration is finished, you can shut down your computer and change the boot order to boot from your new hard drive. If it works properly, you can go to the next stage.

Option 2: Clean Install Windows 10

If you expect a fresh system without any hidden corruption or you don’t need to move your data to the new boot drive, you can clean install Windows 10. To do this, you need to download the latest Windows 10 installation ISO file from the Microsoft website and burning it to a USB drive or CD/DVD, and then use the USB drive or CD/DVD to install Windows 10.

Here are the detailed steps about how to clean install Windows 10.
