I have replied to your mdv question but to be rude
it looks like you would be better off ....in the short term....just downloading a good live cd to see how things are in the linux world
suggest either
knoppix
mepis 6.5
you can read reviews at
www.distrowatch.org
2) it is possible you do not know how to partition but there is not enough info for me to know that
http://www.linuxnewbieguide.org/
and other sites may help?
