Cannot extend W7 C: Drive Partition

Hi All,

I am running a RHEL 6 laptop with a Windows 7 KVM virtual machine loaded.

I am needing to expand my virtual machine's hard drive space allocated, so I used the KVM's inbuilt function to allocate an additional 20GB. There was no errors when performing this task.

Then, I open up my virtual machine only to see that the additional 20GB had been allocated to the C drive, however I don't have access to it (as you can see in the screenshot below). Any ideas how I can resolve this?

Thank you in advance!

You should be asking in a Linux forum for best support. I remember the same issue not long ago but we didn't have any resolution. Perhaps you should try: fixmbr or load defaults in virtual BIOS (if there is any such feature)

I see nothing to allocated. No room.
Their is a very small drive with 98% used.

Yeah that is the problem. I have extended my drive but cannot find any disk space to allocate.

Thanks, i'll take your suggestion. If not, i'll contact our help-less desktop support.

The thread I mentioned - How to find the missing space in the disk.
See a resemblance? :)

fixmbr as in run in cmd in recovery environment
Bootrec /Fixmbr

Ah, I found out a solution. Instead of increasing the volume using KVM, I decided to extend it using "qemu-img resize vmdisk.img +10G". That gave me some "Unallocated space" for which I could extend my C: Drive partition to, and in turn also free'd up the 20GB that was somehow lost (in the above picture).

Either way, it is resolved. Thanks for the help guys.

Thanks for sharing! Will help the next person :)
