local development enviorment

I'm trying to create a local development environment on ubuntu.

I've imported an existing website that I've created on windows.

All the css \ images\ js and links are relative to the root's path, example:

/css/test.css

On my local host it should be

/mysite/css/test.css

I can't figure out how to fix it.. I've added a virtual host, updated the hosts file and even added some new rows to my htaccess..

But without any change..

Thank you!
