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.

 

Cannot merge C drive (disk 0) with unallocated space (on disk 1)

Hi all,

I need some advice on whether it is possible - and if yes, how to merge my C drive on disk 0 with D drive on disk 1.

The problem is: my C drive is getting full soon, but previously after I deleted D drive and make it unallocated space (the bar of current D drive will change to black from blue), I still cannot expand C drive by adding the 100GB unallocated space into it.
If I right click on C drive, the "expand" item is in gray.

I've searched online for solutions but so far only have seen same questions around. Does any one know the solution and do a big favor to explain how to do it step by step? Thanks much in advance!

P.S, sorry that the interface is not in English. Below page shows the "Disk Management" function, and you can see that:

1) Disk 0 has 55.78G, including C drive (55.21GB), 100MB of something I don't know what it is, and 473MB of recovery zone

2) Disk 1 has 100GB D drive, and 831.51GB E drive

 

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!
