Is there a way to determine if a OS partition is MBR or GPT?

[BobBuilder]

I have a bunch of image files of MBR and GPT Windows 7 OS partitions, is there a way to determine if the OS is MBR or GPT by looking at the files? Like I know there is a way to determine Windows version by looking at ntoskrnl version number.

 

Thanks in advance.

P.S. also if anyone knows a way to convert MBR to GPT and vice-versa, it would help a bunch

Look at windows disk management.

I have image files, not drives, so no, that would not work

If you're in windows, open Disk Management and it will tell you. Right click the disk (not the volume), go to properties, then the Volume tab. It will tell you the disk partition type.

Thanks but I have image files of the drives, not actual drives.

You asked how to see if a drive was GPT or MBR.

Don't pretend like I didn't see you edit the title and post.

I'm fairly certain the partition type doesn't leave residue on the files themselves.

 

Edit:

Maybe if you had a disk dump you might see something? In the raw file itself there will be no difference.

I did edit the title, but the post was NOT edited, I saw how you guys could just read the title and mistake the question, so I edited the title. the original POST was not edited though.

Also, I appreciate your help, but I'm not PRETENDING to hide the fact I edited the title, if you had read through my post, you would have saw what I actually meant. Thanks for trying to help though.

Don't you make the system image MBR or GPT when you are creating a boot drive?

Hmm, is that possible with images in the .GHO format?

[BobVonBob]

Wait do you just have pictures of the drives themselves?

 

No. There is absolutely no way to tell if it is partitioned as GPT or MBR just from that alone unless the disk is larger than 2TB. If it is it will be GPT, since MBR only (usually) supports 2.2TB

No I have disk images, not like actual jpeg images, like I have a copy of the contents of the OS partition of the drive that I could clone to another drive and it boots.

The problem is that when I restore a MBR image to a GPT formatted drive or vice-versa, it doesn't boot

Sorry what is a disk dump? is a ghost image file counted as a disk dump?

Oh that kind of disk image. I've got no idea. You could check if someone knows the answer over on Symantec's forums, since the files would have been created with Symantec's Ghost software.
