DX58SO doesn't recognize HDD

Apparently every time I boot up, it says "hard drive not detected"


However, the hard drive shows up in BIOS (Samsung sinpoin...). I can boot up into the hard drive if I
have a vista OS DVD in the DVD drive. It says "hard drive not detected" then goes into "do you want to boot from DVD" - after not pressing anything, it boots up into the harddrive and enters windows. I have no idea what is going on...it can't boot into the harddrive unless I have an OS in the DVD, and keeps saying it doesn't detect the HDD. I've tried installing, reinstalling the OS in two different partitions.

I've also tried flashing an older BIOS onto the mobo and a newer sox5810J BIOS as well...no luck.


Anyone have the same problem?

OK, I admit this is a really dumb question, but does your boot order in BIOS have the hard drive ahead of the DVD? If so, switch these and you should be able to format the hard drive and then load Windows from the DVD so it boots normally from your hard drive.

Now after I switched some settings and used another BIOS, I can boot into windows without having to use the OS DVD. However, it still says "hdd not detected on boot up."
I'm going to do a wipe to see if that'll solve anything.
