Why unboot USB pen drive to normal?
Sometimes, you create a bootable USB or SD card to access your computer and fix the boot issue and do other operations. After that, the bootable USB maybe not necessary any longer, and you may want to unboot the USB stick so that you can reuse it as a storage device to store or backup data and files again.
Compared with a normal USB pen drive, a bootable USB stick contains a starting program and a pre-stalled Windows environment. Thus, you just need to delete the starting program and Windows environment by formatting and your USB will be converted to its normal state.
Now, let’s see how to unboot your bootable USB/SD/disk to normal.
3 methods to unboot USB pen drive to normal in Windows 11/10/8/7
Here we are going to provide you with 3 methods to help you to restore USB pen drive to the normal state in Windows 11/10/8/7.
Plugin the bootable USB stick. And follow the steps to format USB with disk management.
