try this in your Windows guest

right click on my computer and select manage
Go to the disk management
Right click on the drive and click extend volume
Confirm the amount of extension. By default this will be the drives maximum.

I'm not sure Matt. It works for others. Hopefully someone else may have an idea.

you could try doing a search on something like, can't extend volume Windows 7. There may be a reason it fails on metal as well.

I just tried it with my Windows 7 guest. I enlarged it 20GB. Started the guest and my extend volume was not greyed out and it worked. when your .vdi was only 50GB did you partition it? did you have snapshots when you resized it?

[Matt USA]

I believe the answer to when my .vdi was only 50GB did I partition it? is No
Did I have snapshots when I re-sized it the answer is Yes?

you are not supposed to resize a .vdi if you have snapshots unless you actually resize the highest numbered snapshot.vdi. I'm not sure how one goes about fixing it if you resized the guest .vdi instead.

I confess I do not understand loukingjr when you say "you are not supposed to resize a .vdi if you have snapshots unless you actually resize the highest numbered snapshot.vdi. I'm not sure how one goes about fixing it if you resized the guest .vdi instead." This is my first VM
I found this thread here: http://social.technet.microsoft.com/For ... proinstall

" You certainly can extend a boot volume in NT 6.1 (Win7/Server 2008 R2), as long as you first convert the volume to a dynamic disk. You do this by right-clicking the Disk (not the volume) in Disk Management and clicking "Convert to Dynamic Disk", or by running the required commands using diskpart.

I can do it but am nervous! I think I will sleep on it and check to see if anyone else chimes in with suggestions.Thank you!

You should read this
How to resize a Virtual Drive

Please don't send me questions by personal message: stick to the forums.

To address your problem as simply as possible: you can't resize a drive if you use snapshots. So, you need to get rid of the snapshots - utterly get rid of them, as if they had never existed. The easiest way to do that is to clone the VM: when asked you answer full (not linked) clone, current state only, and don't reset the MAC address.

You will then be able to resize the clone VM's disk. After thoroughly testing the clone you can delete the old VM. I suggest you avoid snapshots in future.

Hi, I created a video tutorial that shows step by step how to successfully resize a Fixed .vdi drive. Since this is my first post here, I am not able to post the link, I will add it later. But here is a summary of each step I walk you through.

01 Introduction - Yes you can re-size a fixed VDI drive
02 Review 6 Steps to re-size successfully
03 Release and remove (don't delete!) the Fixed VDI Drive you want to re-size.
04 Use command line CMD (run as administrator) Navigate to VboxManage Directory.
05 Clone the drive with VBoxManage clonehd.
06 Resize the VDI Drive with modifyhd.
07 Start Virtualbox, add new cloned VDI drive and extend partition.
08 If your OS does not have a Partition tool what can you do?

Or, you could just do all that in one step with CloneVDI.
