Change USB-Drive from GPT to MBR

Most USB drives have a MBR partition style and will work fine on our CTOUCH screens. In case your USB drive has GPT (GUID Partition Table) please follow the steps below to set it to MBR

WARNING back up all files from your USB-Drive before proceeding and instructions below are on own risk since selecting the wrong disk can erase all of your PC's data!

Open Disk Management on your Windows PC

Check if your USB-Drive is GPT by right clicking the desired disk (6 in our case) and choose properties

Here you you can find the partition style from the Volumes tab

Since our USB drive has a GPT partition style as shown in the picture above you can close Disk Management and proceed to the next step to convert it to MBR.

Use Windows search to find Command Prompt and right click on the result to run it as administrator.

The command prompt will pop up:

Now type diskpart and press enter

Type list disk and press enter to see all available disks (only drives marked with * are GPT)

Type select disk followed by the correct number and press enter to select it. In our example disk 6

Only if you are 100% sure the correct disk is selected type clean and press enter

Now type convert mbr and press enter to go from GPT to MBR 

In case you want to proceed with formatting the USB drive please type the following command:
create partition primary



Type select partition 1 to select the newly created partition

Type active to mark the current partition as active

Please type the following command to format the USB drive as Fat32 and give it the name Data.
format fs=fat32 label=Data quick

Now you are set and you can close the Command Prompt
