Windows 10: [MBR 2 GPT] Move or create new system partition

Hi,I want to enable secure boot on my SSD to install Windows 11, but I first have to convert it from MBR to GPT. The command mbr2gpt /convert doesn't work because my boot partition and my system partition aren't on the same drive - the system partition is on an old drive drive 0 on the screenshot where Windows was installed before I get my SSD drive 4 on the screenshot.Is there a way to move the system partition or to create a new one the my SSD without being forced to reinstall Windows ?Thanks for your help !

:)

 

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.

 

Convert only one partition on the disk from MBR to GPT

Follow the steps listed here on using GPTgen. He also lists how to create and restore backups.

clone MBR HD to bootable GPT partition?

My HP Vista laptop took a swim and died. I pulled the 320MB HD, put it in an external enclosure and found it still good. Bought a new Dell Win 10 machine w/ 1TB HD. Plan was to:

• 
  Partition off a piece of the new 1TB w/ native Win10 Disk Management.
  
• 
  Clone the 320MB Vista drive into the new partition w/ Easeus Partition Manager.
  
• 
  Run Paragon-adaptive-restore on the Vista partition.
  
• 
  Set up as dual-boot Win10 / Vista.
  

Ran into problems right away. Apparently can't clone the MBR HD to a GPT partition and have it remain bootable. Don't see a way to do this without wiping the new Dell 1TB clean – which I'm hesitant to do, especially since I'm about 6000 miles from
home right now.

• 
  What's the solution to cloning the MBR drive to a bootable GPT partition?
  
• 
  Am I on the right track? I really want to preserve this Vista installation - I have 30+ years of data in legacy programs on it that would be very difficult to access in Win10.
  

TIA
