I have a dell xps 420. I'm trying to in snstall snow leaped but I can't get past the bios. The machine is wiped clean so there is no operating system. Ive read some tutorials but I haven't found a concise step by step guide.
To install what do I need to do exactly to get past the bios? Do I néed t install with a key drive? Is that a must? I can't boot from a cd it just won't work
What do I need to get this going correctly? What do I need to search for?
