Check BIOS settings. Your PC should boot on the hard disk that contains your OS.

Turn the computer on, and watch the bottom of the screen closely.
It'll say something like:
Press "some key" to enter setup
Press that key, and you'll get to BIOS.
Look for "boot order".
It should read:
- floppy (if any)
- CD drive
- hard drive/fixed disk
