Could not find an open hard disk with UUID for FreeDOS

[Tae]

When you launch VirtualBox, the virtual machines complain about missing FreeDOS disk.

Could not find an open hard disk with UUID .

This information is not sufficient. Please attach a VBox.log file of this VM session. Please also attach the .vbox file of your FreeDOS VM (should be in C:\Users\YOURID\VirtualBox VMs\) as well as the VirtualBox.xml file (should be in C:\Users\YOURID\.VirtualBox\VirtualBox.xml).

You’ll stop making VirtualBox being an link. Attached vbox files.

The global .xml file is still missing (VirtualBox.xml). But looking at your .vbox files I already saw that the hard disk with the UUID d99d9354-d62a-4b39-8743-e7d4ef2f0af9 is attached to both, the Windows 2000 VM as well as to the FreeDOS VM. But I cannot say more without the VirtualBox.xml file.

VirtualBox XML file.

You’ve added VirtualBox XML file.

How to fix this problem?

[Frank Mehnert]

I don't know why you came into the situation that FreeDOS.vdi isn't accessible anymore but I assume that the path information is missing in the .vbox file. I suggest you to open VirtualBox, select the FreeDOS VM, remove the hard disk from the settings and then add the hard disk again (of course you have to know the location of FreeDOS.vdi on your hard disk). When you re-add the .vdi file to the VM, the absolute path should be stored and the VM should work again.

You have never tried it.

Please reopen if still relevant with a recent VirtualBox release.
