un-partition linux Ubuntu on flash drive

[trainwizard]

I booted ubuntu from a cd and it started up fine. The trouble came when I tryed to save it to my 4 gig flash drive I'm not sure why it crashed but I think it was just the wrong version (not flash drive compadible). When I restarted I found that Linux had not installed anything on to the drive but had still partitioned it to 3.3 gigs of my 4. I now have a 700mb drive and windows will only format that 700mb. A friend told me to delete it in linux but I don't know how and his instructions were not the best. Please help.
