Can I increase my hard disk space in virtual box which is running Windows 7 currently?

I have my first attempt to install an OS using virtual box and for that I made a 25 gb partition to my hard disk and now I want to increase its size. Is that valid, and if yes, how can i do it?

Solution 1:

For example in order to increase the virtual disk size to 60GB you need to run the following command:

VBoxManage modifyhd "/home/agha/VirtualBox VMs/agha rehan abbas/agha rehan abbas.vdi" -–resize 60000 (size is in MB)

Then you need to start you Windows machine and go to Control Panel -> Administrative Tools -> Computer Management -> Disk management right click the disk and select Extend volume to add the unallocated space to the current volume.
