GPT disk conversion for both data drives and C drive


Macrium Rescue disk can be used to convert from MBR to GPT and vice versa without doing a fresh install of Windows.

1. Download Rescue6.1.1081X64.iso - Google Drive and use Rufus to create a bootable USB disk. Skip this step if you've already created the Macrium Rescue disk.
2. Download: BootEFI_Only-00-00.zip - Google Drive . Unzip to an external or an internal HD
   NOTE: This is a copy of the first 3 partitions of my current Windows 10 x64 (450MB Recovery, 100MB EFI and 16MB MSR)
3. Boot up Macrium Rescue disk and create a backup of your current Windows to another internal/external HD. It serves 2 purposes: you'd have a backup of your current Windows in case things go wrong and then use it to restore the C drive on the next steps.
4. Next, switch the BIOS to UEFI and use Macrium to restore the first 3 partitions downloaded in step 2 to your current MBR Windows. No need to convert or Format, Macrium will do it.
5. Again with Macrium, select the backup image from step 3, and copy back the C drive after the 3 partitions.
   After this step, you should have: 450MB, 100MB, 16MB and C drive (GPT partition scheme)
6. From Macrium, click on Fix the Windows Boot Problems
7. Reboot. Your Windows should be in UEFI mode.

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?
