To boot a Windows computer from an SD card, you need to make the SD card bootable first. There are generally two ways to do this:

• Download a Windows ISO file that contains the installation files required for the Windows operating system. You can get the Windows ISO file from the official Microsoft website or other trusted sources.
• Or you can also migrate your computer operating system and applications to the SD card by cloning them.

Step 4. When the process completes, you'll see a confirming message, asking "if you want to start up computer from the clone target disk". 

• Reboot Now means to reboot your PC and configure the computer to boot OS from the new disk immediately.
• Done means you want to make the changes later. 

 

By using this way, you can also install Windows 10 from USB.

Guide 3. Boot OS From SD Card

Upon successfully creating a bootable SD card, the subsequent stage involves booting your operating system (OS) from the SD card. This allows you to start up and run your computer using the Windows installation on the SD card, providing a portable and independent Windows environment.

To ensure that your system prioritizes booting from the SD card, you need to modify the boot order within your computer's BIOS settings. Here you will need to prioritize the SD card as the primary boot device. These are the steps you need to boot Windows from an SD card:

Step 1: Insert your bootable SD card into your computer and reboot it. During the rebooting process, use the BIOS key to open BIOS settings. The key differs for each model and brand. It can be F2, F8, Esc, F10, etc.

Step 2: When in the BIOS menu, select "Enter Setup" and move to the "Change Boot Order" option on the following window. Now use the arrow keys to give the SD card the highest boot priority. Afterward, save the BIOS settings and reboot your system to boot from the SD card.
