Hi there. I'm having a problem that I've never had in the 12 years I've been glued to my computer screen. A couple of days ago I decided to go with a dual-boot setup, Linux and Windows. I didn't keep the dual-boot for more than a couple of hours so I decided to format my drives. After having formatted my drives I wiped my RAID-0 consisting of 2x SSD's and installed Windows 7 on this raid. The installation went fine and I am writing this from the computer that I am having issues with. The issue that I am having is that I am unable to boot Windows 7 unless the Windows 7 installation DVD is in the tray. Here's what happens: A1. Boot without Windows 7 Installation DVD insertedA2. After POST and the raid-check stage I get a blinking underscore that just sits there, blinking, forever.B1. Boot with Windows 7 Installation DVD insertedB2. After POST and the raid-check stage, I get the "Press any key to boot from CD/DVD". I ignore it, and after the timer has completed Windows 7 boots up normally. I've tried "Startup Repair" via the DVD, which returns a message saying "No error detected.". I tried "bootsect /nt60 c: /mbr", no difference. Any suggestions? Edit: The whole ordeal started with "Missing operating system" and GRUB errors. I therefore decided it was time to wipe my drives, and wipe the MBR before I reinstalled Windows 7.
