I'm emulating Ubuntu using VMWare and I've upgraded it to last stable 10.04 version.
When I boot the system I get this error (below the Ubuntu logo):
"an error occurred while mounting /mnt/hgfs"
I made a screenshot: http://dl.dropbox.com/u/72686/mountError.png
So I have to click S to continue and the the OS seems to work well.
Thanks
