Windows 10: MBR to GPT; 25GB Factory Recovery partition for windows; ASUS laptop

I have an ASUS laptop with a 25GB factory recovery partition of 64bit windows on MBR disk drive. Since this partition contains the image of windows 64bit which should support UEFI and GPT, will I be able to use this partition for factory recovery if I convert my drive from MBR to GPT?

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.
