can't unmount cd image in virtualbox
This is a followup question from Can't save data or settings in VirtualBox
In summary: I can't save any data in my fedora inside of Virtualbox. I went to the devices tab, then cd/dvd devices, then remove disk from virtual drive, and I got the error that it was unable to unmount the cd image. It seems that I did something wrong with my installation. What can I do to fix this issue?

Shut down the machine then unmount the CD. My guess is (still) that you're booting to the LiveCD. It can't unmount because it's in use, because it is the operating system. Shut down the virtual machine and unmount the drive, then start it back up and see if you can save anything.
Once the machine is powered off, select the machine and click settings.
Select Storage, click on the iso image (I used TRK because it was handy), and then click unmount.
Respond to the dialog box, press ok, and voila!
No bootable medium indicates that you were running off the LiveCD all along. Follow one of the many guides online to install Fedora properly, or simply download a vdi and import it into VirtualBox.
I'd write these up but it seems redundant and beyond the scope of the original question.
5You will have to edit all the xml files, the main one and the machine(s) referring to them. Just search for the uuid.
