First we should probably work on the type of laptop that you have.
In your thread title you state that you have a "acer inspiron 9100"
But I do not believe that acer makes a inspiron 9100. On the other hand dell makes one. So let's get that straight and then you should. Probably have a look at the wiki and the sub forum here on working and non-working hardware and see if you computer has been reported.
Also might wanna try booting in vesa mode. See the wiki for more info on boot cheat codes.
