How to enlarge a win VM

I had to enlarge a win VM because I made some bad calculation when I created it...

Virtualbox

1. Switch off the VM (do not save the state, properly switch it off)

2. In virtualbox go to file > Virtual Media Manager

3. Select a virtual hard disk in the list and use the “Size” slider at the bottom of the window to change its size. Click “Apply” when you’re done.

Extend your C:\ partition

1. Start your windows VM

2. Search for disk management in the start menu and click on this

3. If possible extend the C partition

Recovery partition in the way of the extention

If you can not extend it probably means that the recovery partition is in the way of the extention, no worries!

• If your disk management looks like this it means your recovery partition is blocking the extension of the C Drive

• You will need to delete the recovery partition so that you can extend C with the new space you added

• Search for diskpart in the start menu and launch it as admin

diskpart

1. list disk

2. select disk <number> (choose the disk number for your C drive)

3. list partition

4. select partition <number> (choose the recovery partition)

5. delete partition override

Extend your C

• Now if you co back to disk management, you should be able to extend the C:\ partition

• Do it and reboot :)
