If you’re seeing the message “We couldn’t create a new partition” or “Windows Setup can’t find or create a partition” during installation, it usually means that Windows is having trouble configuring the target drive.
This issue commonly occurs due to:
A USB installer confusing the Windows setup process
Existing partitions or drive formatting errors
Drive not being listed as the first boot device
BIOS settings like RAID/AHCI interfering with detection
Drive is not correctly initialized or previously used in a different OS (e.g. Linux/Mac)
Leave only the drive where Windows will be installed
Disconnect other internal or external storage devices
Also unplug secondary USBs, hubs, or dongles
Then restart the installer.
💡 This will erase all data on the drive. Be sure to back up anything important first.
At the “Where do you want to install Windows?” screen, press Shift + F10 to open Command Prompt
Enter the following commands:
diskpart
list disk
select disk X ← (replace X with the disk number)
clean
exit
Close Command Prompt, click Refresh, and try again
Windows should now be able to create a new partition from the unallocated space.
A faulty or outdated installer can also cause this error.
Use the official Media Creation Tool to recreate the installer:
Windows 10
Windows 11
Make sure to use an 8GB or larger USB stick and format it cleanly before re-creating the installer.
Using a USB 2.0 port helps avoid driver issues that could interfere with disk detection during setup.
