I am using a server. Since, MBR is limited to 2 TB. How can I convert it to GPT. I know it is very simple but, have question as below
1. Will there be any downtime of partition?
2. Will I loose my current data located on partition ?
3. If I have 2 TB partition, how much time will this take to get convert into GPT.

Hi azahri miya,
In case of something wrong, suggest you could backup your data first.
In addition, you could refer to the thread discussed before.
Best Regards,

Three methods in total:
1. Delete all volumes in Disk Management and then convert the disk to GPT. You cannot do that on system disk unless you have bootable media.
2. Delete all partitions using Diskpart and then run convert gpt. Also, you cannot do that on system disk unless you have bootable media.
Deleting partitions means deleting stored data. It is suggested to backup all partitions before you start. Then, restore the backup image after converting to GPT.
3. Convert Server from MBR to GPT without data loss using third-party software. It works on both system disk and data disk. No need to prepare bootable media because you do the operations under Windows and it will complete the converting within several reboots.
