SSD in AHCI and Parallel Mode problems

I had to reset my BIOS today and can't remember whether my 160GB SSD drive (model ssdsa2m160g2gc) was in AHCI or Parallel mode. I put it in AHCI mode and it wouldn't boot. So I changed it back to Parallel mode. It still wouldn't boot. So I began doing some research on this and discovered that if I were to change the mode, I'd have to reinstall Windows 7. My fear is that if I should have begun in Parallel mode after resetting the BIOS that I now have no way of booting into the drive without reinstalling Windows 7. If I selected the wrong mode, did it affect the hard drive as it is or should I have been able to boot normally if I made the right selection? BTW, I can boot to the Windows 7 CD and I can select repair the installation and in the Windows Explorer I can see all the files on my hard drive, but the system folder is not recognized by the boot loader. I've tried repairing the installation and that still doesn't work.

If you have to Re-Install start with sys in AHCI . otherwise you have to do a regedit , ( tricky )
