OS on MBR, other disks GPT

Hi,

Problem

I don't see the Data Disks in the Windows Explorer

History: What I had before the problem occurred (worked fine)

• Disk 1: 4TB / GPT / Used as Data Disk
• Disk 2: 4TB / GPT / Used as Data Disk
• Disk 3: 4TB / GPT / Used as Data Disk

What I actually have

• Disk 0: 450GB / NTFS / 2 Partitions / used as Windows 10 Pro OS Disk
• Disk 1: 4TB / GPT / Used as Data Disk
• Disk 2: 4TB / GPT / Used as Data Disk
• Disk 3: 4TB / GPT / Used as Data Disk

What I see in the Windows Disk Management

What am I doing wrong?

Convert only one partition on the disk from MBR to GPT

Step 2
Convert MBR to GPT without data loss

 

clone MBR HD to bootable GPT partition?

Hi,

1. You cannot convert mbr to gpt without data loss. otherwise, you can follow directions here:

FROM WINDOWS RECOVERY CONSOLE:

To change a master boot record disk into a GUID partition table disk using a command line

• 
  Back up or move the data on the basic master boot record (MBR) disk you want to convert into a GUID partition table (GPT) disk.
  
• 
  Open an elevated command prompt (right-click Command Prompt, and then click Run as Administrator) and type diskpart. If the disk does not contain any partitions or volumes, skip to step 6.
  
• 
  At the DISKPART prompt, type list disk. Make note of the disk number you want to convert.
  
• 
  At the DISKPART prompt, type select disk <disknumber>.
  
• 
  At the DISKPART prompt, type clean.
  

2. I'd suggest converting your vista drive to a virtual machine, load that up on your windows 10 system and use a program like virtualbox to run it.
