To put some of these claims to the test, we decided to pit Mac OS X 10.5.8 Leopard against Mac OS X 10.6 Snow Leopard to see how these new technologies affected overall performance. Hi I have a white Macbook A1181 which I have upgraded the ram to 4gb and the HDD from 160gb to 320gb. Currently it is set up to bootcamp from Snow Leopard to Windows Vista (I know crap but the only legal copy I had of Windows at the time). I would like to upgrade to Mountain Lion but if I.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Macbook A1181 Latest Os
If your optical driive (CD/DVD drive) isn't working you'll need to use an external drive to install the OS. I wouldn't install 10.4 Tiger though. Tiger was coded for the old Power PC processors with code added to make it work when Apple switched to Intel processors. 10.6 Snow Leopard was the first OS written specificly for the Intel processors.
The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard

To Install an OS from a DVD
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the 'c' key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
