Virtual machine is not reading the virtual hard drive

[felipeam86]

I have Windows XP installed in a virtual machine (VirtualBox) under Ubuntu 8.10. Today I tried to launch windows but immediately I got the message:

FATAL: Could note read from the boot medium! System halted.

Actually I dont care if I lose Windows but I have a very important file in one of the two virtual hard drives associated so I launched a live linux distribution (puppy 4.2) that enables to mount ntfs hard drives so that I can recuperate my file. I was able to mount the secondary hard drive but note the principal hard drive where I have windows installed and the file that I need. So, thats why I put as a topic that the virtual machine is not reading the virtual hard drive... I think it's messed up

I've seen various posts regarding the same error message but they didn't helped a lot, I think they had different problems. I tried to mount the VDI as another partition but apparently as my VDI is dynamic its not that easy to accomplish.

Does anybody has a solution? Remember that I only care for that file in particular I dont need to recuperate windows.

Thanks in advance.
