Before checking this link, i had always been using Disk Management or Diskpart to convert disk from MBR to GPT, or GPT to MBR. But everytime i need to first delete all existing partitions on the selected disk, then i can successfully finish such conversion, so i have to first move important data from the disk to another, then convert it to MBR or GPT, then get data back again. So so time-consuming! But now everything gets changes. Use the recommended software, i can freely convert disk between MBR and GPT without removing partitions or losing data.
Sometimes, you might find the option convert to MBR disk not available or greyed out in Disk Management. So what you should do next? No further worries! AOMEI Partition Assistant allows you to convert GPT to MBR with ease, and avoid data loss.
