Solve the Windows To Go U disk without a drive letter

We have to use the Windows built-in Diskpart command line tool to reset the disk:

1. Open the cmd command prompt window (to the administrator Identity Run);

2. Execute diskpart, and list disk, find the number of your USB drive (in this case, 1), and then select the disk by select disk 1;

3 Execute the clean command to clear all data, format, and post-initial information on the disk (this is the step to clear the NODEFAULTDRIVELETTER flag);

4. Next, you must create a disk partition for Windows to format. For U disk, we default to a partition, so execute create partition primary.

5. To use the disk, you have to format it. However, if you are fed up with the command line, you can finally go to the resource manager to format it~ If you still like the command line, then we can continue to execute format fs=fat32 quick.

Execute exit twice and exit the diskpart tool and cmd. Now the U disk is back to normal, and the computer will get an automatically assigned drive letter.
