my ubuntu is not starting up properly on my laptop please help?

It sounds like your root filesystem is damaged. You might try pressing the shift key when the machine is booting. This should bring up a few boot options that might help you, possibly including an option to load an older version.

Diagnosing and repairing the problem from that point would require more investigation. You would do well to post your problem on a more technically-oriented site.

Have it use each and all the stress (this would get rid of the homestead abode windows installation).
