Caution: Converting a disk drive from MBR to GPT or conversely erases all data from the drive. Ensure that all files have been backed up to a different hard drive or storage device before following the instructions below.Converting from GPT to MBR won't erase your data, but it's crucial to back up your data before making any changes to your partition table. The conversion process changes the way your hard drive is partitioned and how it's interpreted by your computer's operating system.Re: How do I convert MBR to GPT without losing data

1. Open Command Prompt as an admin.
2. Type mbr2gpt /convert /disk:X (replace 'X' with your disk number).
3. Hit enter and let it do its thing.

Should I pick MBR or GPT : Choosing the Best Partitioning Scheme

MBR is compatible with legacy and older operating systems that do not support GPT. On the other hand, if you have a newer computer with UEFI firmware, GPT is recommended for better compatibility and support for modern features.

Can I use MBR and GPT at the same time

Mixing and matching GPT and MBR disks on the same system

GPT and MBR disks can be mixed on systems that support GPT, as described earlier. However, you must be aware of the following restrictions: Systems that support UEFI require that boot partition must reside on a GPT disk. Other hard disks can be either MBR or GPT.

Is it OK to clone MBR to GPT : Luckily, the answer is Yes. If you're in the same case, you could read this article to check how to clone from MBR to GPT.

To answer OPs question – initializing a drive does NOT erase the contents of the drive.

Here are the detailed steps:

1. Run EaseUS Partition Recovery on your PC. Select the disk or device where you lost partition(s), click "Scan" to continue.
2. Wait for the scanning process to complete.
3. Preview and restore the lost partition(s).
4. Click "Recover Now" to finish the partition recovery process.

How to tell if drive is MBR or GPT

In Disk Management, right-click on the Disk # that you want to check, then click on Properties, and it will open a new window. Go to the 'Volumes' tab and there you will find Disk Information. There you will see if your Partition Style is MBR (Master Boot Record) or GT (GUID Partition Table).There is no big difference between GPT and MBR besides the partition number and disk capacity. Most geeks suggest that GPT is always better than MBR because GPT is newer, while MBR is not much used any more and because GPT is more widely used on most modern operating systems.Because the maximum number that can be represented by using 32 bits is 4,294,967,295, it translates to 2.199 TB of capacity by using 512-byte sectors (approximately 2.2 TB). Therefore, a capacity beyond 2.2 TB isn't addressable by using the MBR partitioning scheme.

If you have a hard drive that you would like to use and it is 2 TB or smaller, select MBR when you initialize the hard drive for the first time. If you have a hard drive that you would like to use but not boot from and it is larger than 2 TB, select GPT (GUID).

Can MBR and GPT be same system : You can't have MBR and GPT on the same disk. You can use separate MBR and GPT disks together on a Windows computer. MBR and GPT are types of partition tables; they are not file systems. You can have two partitions formatted with different file systems but you can't have two types of partition tables in the same disk.

Is MBR bad for SSD : 2. Use SSD as 2nd disk or data drive: MBR is probably the best option if the SSD is 2TB or less incapacity. If the SSD is greater than 2TB in capacity, GPT is perhaps the better option.

Should I initialize disk MBR or GPT

If you have a hard drive that you would like to use and it is 2 TB or smaller, select MBR when you initialize the hard drive for the first time. If you have a hard drive that you would like to use but not boot from and it is larger than 2 TB, select GPT (GUID).

Try the MBR2GPT conversion tool

As an alternate approach, you can use the MBR2GPT.EXE tool to convert the MBR disk to the GPT partition format.Luckily, the answer is Yes. If you're in the same case, you could read this article to check how to clone from MBR to GPT.

Should I use MBR or GPT for new drive : Most PCs use the GUID Partition Table (GPT) disk type for hard drives and SSDs. GPT is more robust and allows for volumes bigger than 2 TB. The older Master Boot Record (MBR) disk type is used by 32-bit PCs, older PCs, and removable drives such as memory cards. You don't usually have to worry about partition style.
