Am I going to lose any data?

You could run TreeSize on the host server to see where space is being consumed and then delete unnecessary files:<br />

You could also run CCleaner if you still trust it

Go to the Settings of the VM in HyperV Manager, go to the VHD(x) in question (state MUST be off, not saved!) &nbsp;Click on Edit and then follow the wizard to Compact (this will take some time, but if memory serves USUALLY not more and 15-30 minutes, though clearly it depends on the size and type of the disk).
</div>


<div>
The vmachine is the only thing on that drive. Funny thing is that when I look at the properties it shows the flies are 420gb but the drive itself shows 446GB used.

<div>
You shouldn't, but that's why you have backups, RIGHT?<br />
<br />
The process doesn't normally lose data, but you're mucking around with disks (virtual or otherwise) - it's unwise not to be prepared for the POSSIBILITY that something goes wrong.

<div>
It says edit is not available because checkpoints exist for this virtual machine. Can I just delete the checkpoint?
</div>


<div>
Now I got a major problem. I clicked snapshot to see if there was a dialog for snapshots. I tried to start the machine to see if I can backup an sql file but it says windows failed to start a<br />
<br />
<br />
File: \boot\bcd\<br />
status 0xc000014c<br />
the boot configurationd ata for your pc is missing or contains errors.
</div>


<div>
thats all I did was click snapshot
</div>


<div>
Im sorry checkpoint! not snapshot
</div>


<div>
I deleted the checkpoint and it started normally. So I just need to compact that disk right?
</div>


<div>
I'm not sure about a saved/paused-Critical situation, HOWEVER, in 2012 R2 and later you can delete checkpoints while the VM is running (merger takes longer).

<div>
Thanks for everyone's help. I deleted the checkpoint, then compacted the disk and it freed up 120GB!

I have a major time sensitive issue. I need to get this server online so they can work until later today I can provide a more permanent fix. The Main server 2012 has 25 GB free. When I start the vmachine it goes down to like 30MB. I moved files from the virtual machine to free 25 GB of space but that didn't effect the numbers on the main server.

Hyper V Pause - Critical Disk Space Issue

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
