For MBR-style partition, each partition will have one Partition Type ID. System can tell the types of partitions by the ID. By changing the partition type ID, users can prevent the system using or initializing partitions. This function is not available for GPT-style partitions, as GPT partitions have no partition type ID. The following is the most frequently used Type ID.
Step 1. Launch AOMEI Partition Assistant Professional, right click the drive you want to change partition type ID and select "Advanced" > "Change Partition Type ID".
Step 2. In the pop up window, select the new partition type ID. (take 0X08 fat32 as an example )
Step 3. Click "OK" to confirm your change.
Step 4. Press "Apply" button to proceed.
