I was creating a 48gb partition on my main drive with the intention of installing another OS. Everything was going smoothly, it scanned my drive, and was writing to it, and then my computer randomly shut off. I start the computer again and then it says that message where it asks you to insert the recovery cd. I didn't have one burned at the time, so I booted my other drive, created the cd, and when I came back, a new screen says something like "Missing OS". I do have the ability to boot from the recovery disc, but I'm not exactly sure what I need to do in the options. Any help would be appreciated.
