I put U on my laptop last fall and have not used it for the last 4 months. When I went to start up it is now asking for a startup password. I do not remember putting one in when I installed the program. How do I get around it?

I loaded Ubuntu through WUBI but windows still boots first

I upgraded to Ubuntu 10.04 and now my computer won't start. At first it did but after the last restart it did not boot. It does not show any boot menus or anything. How do I go about booting it from a CD? What do I do afterwards? Thank you very much.

Ok.  Bare with me a second.  Here's my partition scheme;
(200GB)/dev/sda1  /boot  500M/dev/sda2  LVM    100G

• / (root)
• /home
• /tmp
• /usr
• /var

/dev/sda5  swap 4G
