That could mean it's possible your hard disk has failed or that you have some type of virus or malware infection.
You can create a CD/DVD boot disk using another computer. And you also put other tools on that CD/DVD. AVG Rescue CD Guide
Shows you how to create a bootable rescue disk. And it has an AV scaner and other utility programs listed in the Other utilities section.
