Can't Open CDROM Drive While Installing VM Debian 7.6

VirtualBox 4.3.14
Windows 7
Debian 7.6

I'm trying to create a new VM with Debian 7.6. I downloaded the 3 install iso discs and tried to install. When I begin the installation it seems to take control of the CDROM and I am no longer able to eject it by either pressing the eject button or trying to eject through Windows. The installation goes fine until it asks if I have any other discs to install (which I do ... I have 2 more). At this point I say "Yes" but I cannot get the CDROM to open up at all since it doesn't automatically eject for another disc and as I mentioned before ... I can't do it manually or in Windows.

First off ... let me kill a few suggestions right off the bat.

- I cannot do an installation over the internet because this is a government computer which is requires to be hooked to a government network. There are certain certificates required to access the network which are not available to my newly made (or in the process of making) Linux system but rather only to my host Windows system.
- I cannot use a newer version of VirtualBox because that opens up a whole new set of issues dealing with WinVerifyTrust getting CERT_E_REVOCATION_FAILURE most likely due to our symantec security software.

So my Storage Settings in VirtualBox are as follows for my CDROM drive:
- Controller: IDE Controller
- Type: PIIX4
- "Use Host I/O Cache" is checked
- Host Drive D:
- CD/DVD Drive: IDE Secondary Master
- "Passthrough" is checked

I cannot install the Debian 7.6 OS because I cannot eject each disc and put in the next disc. The only way I can eject the disc is if I reboot my entire system (host windows system) which obviously leaves me at an unfinished point in my install and therefore I have to restart the install and end up right where I was 30 minutes earlier.


PLEASE HELP !!!!! I cannot get past this and I obviously need to.

Thanks,
S

CDROM passthrough is not necessary, please disable it. Perhaps that already resolves your problem.

If you still cannot eject the CDROM from the drive, look at the guest. Try to open some terminal. If it's the text-based installer, press Ctrl+F2 (if you didn't change the host key, then use the lef Ctrl key!) to have another virtual terminal. If it's a graphical installer, try pressing RightCtrl+F2 (if RightCtrl is your host key). On the virtual terminal, try to execute 'eject'. If the CDROM is still mounted, try to unmount it. Executing 'eject' should definitely open the tray of your host CDROM drive if the medium is not mounted by the guest.
