“There is no disk in the drive. Please insert a disk into drive” is an error that occurs when you assign a drive letter to an unmounted disk device.

There is no disk in the drive. Please insert a disk into drive


Each hard disk drive, floppy disk or CD/DVD drive will be assigned a drive letter to help users easily identify and access them. However, after removing the above devices, for some reason the system has yet to unassign their drive letters. These drive letters are still in the list of drives but they are not assigned to a real device. This leads to an error when the program checks the drive: There is no disk in the drive. Please insert a disk into drive. AIO Boot Extractor also encountered this problem.


The solution here is that we will unassign all the drive letters that have been assigned to devices that are no longer on the computer. Microsoft has documented how to fix this here.

  1. Open Disk Management, or run the following command:
  2. Right-click the disk device that is assigned to the drive letter in the error message. Here is G :.
  3. Select Change Drive Letter and Paths.
    Disk Management: Change Drive Letter and Paths
  4. Select the drive letter, click Remove to unassign.
    Disk Management: Remove Drive Letter
  5. To remove a disk device from your computer:
    1. Open Devices and Printers or run the following command:
      control /name Microsoft.DevicesAndPrinters
    2. Right-click on the device and select Remove device.
      Devices and Printers: Remove device

Note: After attaching the USB or hard disk to the computer, if you do not see the drives, assign the drive letter manually by clicking Add in step 4.
