Missing OS Error Message?

In my haste to try out the Windows 8 preview, I made a new partition. However, When it warned me about making it a simple partition, I ignored it thinking that I could still use that for a data drive and use a third partition I had as my windows 8 partitionAfter rebooting, I received a missing OS error message no doubt being that all my partitions were turned simple instead of just the one I made. I then used the MSI Recovery which did nothing, but likely removed any and all files I had(no big deal though).Next, I tried my Google-fu to find an answer. It suggested to restore the Master Boot Record, but that did nothing once again. I used this [url=http://bit.ly/iZN0A][/url] tutorial, but in step 3, I didn't even see Windows mentioned. However, I did see my main OS partition and both other partitions on the disk, so I know it's not dead.
