Ubuntu Netbook 10.04 Problems Booting & Wireless

[algomedic]

I've installed Ubuntu 10.04 Netbook for my HP Netbook PC. I have two issues now. I am getting hung up on the booting up. I get a flashing dash in the left hand upper corner that keeps flashing and doesn't show any hard drive activity. It will not load and I have to force it to shut down by holding the on/off button.

Any ideas?

When I did have it running before, I had no wireless capabilities. It shows the Wireless disconnected and I could not connect by any means (wirelessly), wired is fine.

Any ideas for this as well?

Thanks

Correction to my post - Wired also does not work and the iwconfig shows "no wired extensions" and "no wireless extensions"
