We couldn’t create a new partition Windows 10 USB

For USB’s here are reliable solutions to fix the error.

Solution 1 – Use a bootable DVD

Some users complain that their USB 3.0 flash drives cause partition creation errors. USB 2.0 drives are also not immune to this kind of error too. To be on a safe side, install Windows using a bootable Windows 10 DVD instead of a flash drive

Solution 2 – Disconnect additional USB drives from your PC

If you don’t have a bootable DVD but a flash drive is all you have, make sure you disconnect any other flash drive from your PC and leave only the flash drive you are working with.

Solution 3 – Reconnect your USB flash drive

Another trick that may work is to unplug the USB drive from the USB port and then reconnect it. If you still can’t create a new partition, try connecting the drive to another USB Port.

Solution 4 – Set hard drive as the first boot device

Some systems have been known to set BIOS as the first boot device and this often triggers a “we couldn’t create a new partition” to message. To fix it, set your flash drive as the first boot device then reconnect the drive and restart the system again. As the system is booting, press (F12, F11, and F10) to select the flash drive as a boot device.

If the Boot menu is not enabled on your device go to BIOS to change it manually.

Solution 5 – Use a 3rd party Media Creation Tool to create a bootable USB drive

Your Media Creation tool may be the cause of the error message but no need to fret over it. Simply go on online and download a third-party creation tool for free. There are so many of them you can use like Recoverit Partition tool to create a bootable flash drive.

DO NOTE THAT CONVERTING MBR TO GPR WILL ERASE ALL FILES SO MAKE SURE YOU DO A PROPER BACKUP OF ALL YOUR FILES FIRST.
