How to Create Partitions from BIOS in Windows 11, 10, 8, 7 Easily?

Is it possible to create partitions from BIOS?

Generally speaking, BIOS is the firmware used to provide runtime services for OSes and programs and to perform hardware initialization during the booting process. To enter BIOS, for example, on Windows 10, users must repeatedly press F10, F2, F12, F1, or DEL (decided by the manufacturer) during the computer startup. For different purposes, some users wish to create partitions from BIOS and want to know if it’s possible to do that. Although the answer is negative, you can still create partitions before booting into Windows.

Method 1. Create a partition from BIOS using a Windows installation media

By using a Windows installation media and setting it as the first boot device in BIOS, you can create partitions in Command Prompt by inputting corresponding commands. It might be a little difficult if you’re not a professional user, but it does work well.

1. Create a Windows installation media using a Windows media create tool.

2. Boot your Windows PC from the installation media after setting it as the first boot device.

3. Once the Windows Set is fully loaded, you’ll be presented with the window as the screenshot shows. In the windows, you can set the language, time and currency format, and Keyboard or input method. When everything is complete, hit "Next".

4. Hit : "Repair your computer" at the bottom left of the window.

5. Choose the "Troubleshoot" option.

6. Choose "Command Prompt".

7. In the CMD window, type "diskpart" and hit "ENTER" to launch Diskpart.

8. Type "list disk" and hit "ENTER" to list all hard disks on your PC.

9. Type "select disk *" and hit "ENTER". Here, * represents the hard disk where you want to create partitions.

10. Type "list volume" and hit "ENTER" to list all partitions on the disk.

12. Type "select volume *" and hit "ENTER". * represents the partition you need to shrink.

13. Type "shrink desired=10240" and hit "ENTER". Here, we take 10240 for example that’s the amount of space to shrink.

14. Type "create partition primary size=10240" and hit "ENTER" to create a partition.

15. Type "assign letter=G" and hit "ENTER" to give the new partition a drive letter. Here, you can replace other letters as long as they haven’t been occupied by other partitions.

Quit Diskpart and reboot your PC. Then, you’ll find there’s a new partition of 10GB.
