I've had my computer for about a year running XP with 2 harddrives in RAID (mirror). My motherboard, Asus P5NE SLI, has the RAID controller built in. These 2 drives are my only drives (other than an external USB drive). I wanted to get rid of RAID and just have 2 regular drives and install Win 7. I started by deleting the RAID array first. Then went into BIOS and disabled the on-board RAID controller. I verified that my BIOS now recognized both drives (on SATA 3 & 4). I put in my Win 7 DVD and did a fresh install, including deleting the partitions and formatting the two drives. The installation went perfect. All drivers were installed and system worked perfect. I took out my Win 7 DVD and rebooted, only to get the NTLDR missing message right after POST. It said to hit CNTL-ALT-DEL to try again, but the same thing happened. I then put in my Win7 DVD and the computer loaded up perfectly. Upon booting, right after POST, it says press any key to boot from DVD-Rom. I DO NOT hit any keys and it start loading Win 7 perfectly. So the problem is that if I remove the DVD, I get the missing NTLDR problem But if I put in the Win 7 DVD, everything boots up correctly. I'm stomped. I think maybe I un-did the previous RAID array incorrectly and somehow corrupted the MBR? I even loaded from the Win 7 DVD and told it to repair, but I still have the same problem. I'm open to any and all suggestions! Thanks!
