3. Re-read the burned image
Re-read the image that has been burned
This tutorial is for the image that has been burned, but the drive letter cannot be recognized by the computer, resulting in the inability to re-burn the image.
Generally, the win7 system cannot recognize the burned Ubuntu system drive letter. Win10 can use SDformat software to format.
This tutorial takes the USB flash drive as an example. After the solid-state drive is installed in the solid-state drive box and connected using USB, the operation is similar to the USB flash drive.
1. Determine whether the USB flash drive is recognized.
Right-click the computer and select "Manage", select Disk Management, and find out whether there is a removable disk with the size of the USB flash drive.

2. Delete partitions
You can use the partition assistant to delete all partitions of the USB flash drive, and then format the disk, so that the drive letter can be re-recognized, and the image can be re-burned.
You can also use Disk Management to select all partitions. Note that not only the partitions below are deleted, but also the small extra partitions in the list above must be deleted. After deleting, create a new partition and format it into fat32 to correctly recognize the drive letter.
Finally, follow the steps of burning the image and you can re-burn the image.
