Guest Additions is an extra piece of software that unlocks some more advanced features of VirtualBox. However, you might be able to use partitioning software to format the hard drive and make it available to Windows.Previous step Next step 5. TL:DR: Theoretically anything that contains a virtual machine is highly unlikely to help. ) little chance that you can access the host (physical computer) from the guest (virtual machine)

Unless you get very technical in virtual machines or are a highly skilled computer hacker, there is (very very.

So, the virtual machine will have to be stored on the hard drive that windows is installed on.

Since windows can not access the hard drive as is, it is highly unlikely it can use it to provide services to software running on it, like a Hypervizor (e.g Storage).

To create a virtual machine, you need to create a file that will act as a virtual hard drive.

Windows is unable to use the hard drive at its current format.An example of such software is VirtualBox. To do so, you need special software known as a Virtual Machine Hypervizor. One of them has windows installed, the other uses a (currently) unknown linux filesystem. I was able to resize the partition easily using a bit of freeware called EASEUS Partition Master 9.1.0 Home Edition.ĭisclaimer: I loooove deductive reasoning. Further, the partition will need to be resized from WITHIN windows, because you will have this empty space: The vdi must be reattached to the VM after VBoxManage command. But now I can't boot the virtual machine, I get this worrying screen:īy the way, it says FATAL: Could not read from the boot medium! System halted. vdi from VirtualBox before calling VBoxManage command, then adding it back in, was successful. VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBox, interface IVirtualBox, callee nsISupportsĬontext: 'OpenMedium(Bstr(pszFilenameOrUuid).raw(), enmDevType, AccessMode_ReadWrite, fForceNewUuidOnOpen, pMedium.asOutParam())' at line 210 of file VBoxManageDisk.cpp

VBoxManage: error: Cannot register the hard disk '/media/data/winxp_vm/wim.vdi' already exists The suggestion below gives this error VBoxManage modifyhd wim.vdi -resize 20000 Is there an easy way to increase it to, say, 20 GB? I can't see any obvious option in VirtualBox settings.

I have run out of space on my WinXP virtual machine, which I only gave 10 GB space for when I created it.
