I have a problem with partition

Hello, I am new to linux and OpenSuSe. I tried to install it yesterday on my own, to look what linux is like. But there happened an error with partition. Now I’ve only Vista on my computer but the half of my harddisc is away and i cannot take it back. When I want to erase this unused partition in the system panel of vista, it says not eneough memory on at least one medium.
I’ve also tried it with OpenSuse dvd, but it says its unmountable.:frowning:

What could I do, please help me, I’m not so good with Pcs…
