Another "reboot and select proper boot device.."

My Win7 Ult x64 system got hung - so I cold booted. Upon reboot - I saw this message: "reboot and select proper boot device..."

I tried to do a recovery with my Repair disk - but after selecting Keyboard, no Windows installation was detected.

I booted from a Hirens CD to see if my data was present - it was.

After chasing existing answers and poking around myself, I corrected an issue with 2 partitions on two different disks marked as: Active. I left my un-named 100MB partition in Disk 0 as: System, Active & Primary; and the second partition on Drive 0 (my Win7 Ult x64 installation) as: Boot, Page File, Crash Dump & Primary. Both partitions are "Healthy". There are no other partitions on Drive 0. Drive 0 is 2TB in size.

I started to reboot from my Hirens disk again, but instead of booting an OS from the CD (Mini XP, etc.) I selected the top option - to boot from MY HD into Windows 7 - it loaded up and booted perfectly! I can boot this way consistently without fail.

I suspect that there is an issue with the first partition on Disk 0 (Active 100MB) that is preventing my machine from starting properly - but I'm at a loss as to how to fix / access it. Any help would be greatly appreciated. Thanks!

Yes, I have several HD. This drive is an IDE (PATA) on the primary channel there is another on the secondary channel too. I also have 2 additional drives on two SATA channels. The BIOS shows all drives present and the boot order is correct.

The boot order for you HDD drives or boot order in general like optical > floppy>then HDD. There should be a section to select the boot order of your hdd's too. what MB do you have?
