Would you like to force mounting of this medium?Ĭould not mount the media/drive 'C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).Īnd I get a choice to "Force Unmount" the mounted ISO file within (which is indeed the VBoxGuestAdditions).Īlso, when I click on the CD icon on the bottom right of the Ubuntu window so that I can "remove disk from virtual disk", I get a similar error message, except this time it says that it cannot unmount: The correct steps you should follow is (which worked for me at the time of posting): After mounting using: from lab import drive drive.mount ('/content/drive') Unmount using: drive. Have you ever tried to format a disk in Mac OS X and Disk Utility wont Unmount the Hard Drive for formatting It can happen for external (USB and Firewire).
Unable to mount the CD/DVD image C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso on the machine Ubuntu Desktop 12.04 64-bit. Then, when I go to "Devices->Install Guest Additions" within Ubuntu (running it by simply starting VB and clicking start on VB GUI for Ubuntu), I get the following error message: For information about locking a volume, see FSCTLLOCKVOLUME.

For information about using the FORCE option, refer to 'Mounting Disk Groups Using the FORCE Option'. You can also specify the optional FORCE option.
Force unmount disk code#
Is there a separate step to have a selection menu at start-up or does this not apply for VirtualBox runs of Ubuntu? The FSCTLDISMOUNTVOLUME control code will attempt to dismount a volume regardless of whether or not any other processes are using the volume, which can have unpredictable results for those processes if they do not hold a lock on the volume. You can mount or dismount disk groups by name, or specify ALL. Once youve found the disk, type in sudodisktilunmountDisk force/dev/diskx. First, when I restart my computer, it just goes straight to Windows 7, as normal. Look for the disk you want to force unmount and take note of the drives number. I've installed Ubuntu (64-bit version) on a vm through VirtualBox on a Windows 7 64-bit host, but I fear that I've done something wrong.
