Hi Angus, Sorry if I'm stating the obvious here, but I tried to discuss this with you before: You want to use your d: drive for Linux. This menas that it must be empty of files, and must have no Windows partition on it, or at least you will need to delete the Windows d: partition to leave unpartitioned space. If you're intending to install somewhere other than d: than forgive me, but I think that was your intention. Saqib
