Still have not gotten answer yet

I can't booting ubuntu 11.04 when triple booting, windows 7, opensuse 11.4, and ubuntu 11.04. I have written in ubuntu forum, this forum, and other. But still have not gotten answer or solution yet. I am newbie, new in ubuntu. May be ubuntu for this version still have not support for my computer. May be I can try other popular distro. I have seen in distrowatch.com, the second popular of linux is linux mint. I will try linux mint. At least, I have known ubuntu. Thanks for ubuntu for your iso. I have downloaded successfully. May be in another computer, I will install you, if I buy a new one.
