Did you remove all drives but the system drive when you upgraded/reinstalled?

I did not. How does that make a difference?

The Windows 7 boot files may not be on same HD Drive as the OS.

I did not know that was possible. Is that normal? Or unplugging hardrives is the only way to prevent it

Thanks

Yes it is possible. I have had it happen a few times when having all my hdd's attached. Same goes with Linux..
Always best to only have the hdd attached that your installing on for less error to happen.

Please post back a screenshot of your maximized Disk Mgmt drive map with listings showing all columns, using the Snipping Tool in Start menu. Tell us what is on each partition.

What is the exact sequence during booting of the PC?

Here is the Disk Map and some photos of a typical "Opening Sequence". (nevermind the Mac Display, we used to have a mac)
Again, when I go into the BIOS set up, do not change anything and exit w/ saving sometimes computer starts up.

Please let me know if these images show anything out of the norm.

Thank you

also, after lookin over the images i just realized, I had a RAID partition setup in the previous system and i did not go through that during the upgrade to Windows 7.

Could that be the culprit?

Don't mess with RAID and Win7 if not for a very good reason as it can be a can of worms.

As suggested unplug all HD's except target and clean install Win7 adapting the steps given in the Perfect Reinstall link in my signature box below.

Feel free to ask back any questions.

You'll want to make sure any non-OS drives are not marked Active as this can pose problems later.

hey guys,

Thanks for all the replies and yes disabling raid did help but at the same time created another problem.

The motherboard, Supermicro X7DWA-N, by default only supports 4 hard drives but is says it can support up to 6. We have 5 hard drives, that's why we had RAID enabled before.

I guess the the only way out is to properly set up RAID, or somehow get the motherboard to support 6 hard drives.

btw, the computer was set up by someone else, thats why I'm a bit foreign the set up.

Thank you

Thanks for all the replies and suggestions everyone.

It turned out that one of the HDs that were configured as a part of the RAID went bad. I took out the bad HD and everything is working fine now.

Thanks again.
