600E gets I9990305 after BIOS update

[tghlk]

I upgraded the BIOS on this 600E I'm getting ready to sell and after it completed ok and I initialized it, it booted to the 'feed-me' screen and then pressing F1 showed I9990305 which means there's nothing to boot from. plugged the drive into a USB adaptor on a desktop and the hard drive looked ok. I put it back in the 600E and it booted fine. After an update, I shut down and restarted and got the feed-me screen again and the I9990305. I powered it off and then on and it booted fine. Strangely enough, this boot issue only happened AFTER the bios update. Any ideas?

I think you are having a problem with the boot order or initializing the drive.
