Windows 7: Convert MBR Disk to GPT Disk

That has nothing to do with Legacy BIOS or UeFI - your getting yourself confused. Just follow Shawn's advice, and carry on.

Well I am sure I did download the wrong ISO because I used the paid for OEM DVD I originally installed on this machine I built and where it wasn't updating it is going nuts doing so right now.

PW readout is exactly the same and frankly I don't care whether it is MBR or GPT now as long as this fourth clean install works.

Just as a by the by I used a 7 Pro ISO to clean install onto a SSD on the small laptop I bought and PW checks it out as a GPT drive - it is all quite confusing and I was really looking forward to getting back to my machines after 14 weeks in hospital only to find I have run into all sorts of crap.

However one of the main issues I did have with this Ivy Bridge - the losing of replies to threads has now gone - hallelujah!!

Hi,
Ideally you wouldn't have a 100mb partition at all but even if you do nothing wrong with an 100mb NTFS one rather than a 100mb EFI one that Jack shows

You can only create 2 more partitions using the current 100mb ntfs setup and that is "if" you'd want too

Ok Mike look I am not complaining about this I am more curious as to why the drive on reinstall was not made a GPT one. I mean my small laptop did the GPT stuff and why not this machine now??


Yep Colin mate I am getting more confused by the day as it seems to me that any of the OS's are getting very convoluted even the Linux based stuff. I have followed as you say Shawns advice as per I always do but this machine has been functioning for a very long time now in a very odd manner for example replies to posts disappearing never found out what that was all about.

Impossible to convert following above as far as i see.

look at my pic again >>>

NOTE: The unalaocated is div. into two blocks. I see no way to merge them.

both disk management nor mini partition tool offer a solution (as far as i can see)

Your set-up is using the MBR system - This has a maximum partition size of 2TB hardwired into the coding, so the leftmost partition is set to this with the remaining space forming the "partition" on the right, you can use all of the space you have there as is - to do this you need to format the partitions and allocate them a Drive letter - Windows 7 Drive Management does not support the merge Function whereas 3rd party software does

If you wish to create a single partition, as the drive has no data on it at present you do not need any 3rd party software, just the built in Disk Management, you need to delete the existing partitions, convert the whole drive to GPT format, and then re-create a partition of all space

Shawn's Step by step should guide you through the actual process

sorry peeps.... still confused.

right click doesn't offer what Shane's instruction says ??

Shanes instruction was for one space. This damn thing is two blocks both unallocated. Can't seem to merge into one as per shane's info.

You need to right click on the disk area on the left, rather than the partition, you should then see the disk based options - and best to avoid the option of dynamic disk that's offered

Thanks Nigel. right-click on left panel NOT unallocated space section has solved it.
