Windows 7: Problem with boot manager message trying to reinstall Win 7

Problem with boot manager message trying to reinstall Win 7

6 months ago I installed windows 7 on a new PC I built. I then decided to switch to a 64 bit system which I did.
I bought another HDD and decide to add a second drive with windows XP. I ended up with a system which had windows 7 shown twice on boot up and only one would bring up windows 7. Windows XP was missing. I removed the second drive and it worked fine but I still had 2 Win 7 prompts on boot up.
I have a virus or root kit which I can't find or remove so I decided to format the C partition and reload windows 7.
The problem is although I have the bios set to boot from the cd with the Win 7 disk, it comes up with the boot manager missing message and I can't get around this.
I tried another HDD and get the same message.
How do I get rid of this problem where i can re install win 7? TIA

You get the error because the HD is attempting to boot, not the DVD drive.

Set the DVD drive to boot first in BIOS setup: How to Boot your Computer from a Bootable CD or DVD.
Plug in only the target HD.

Next try tapping the one-time BIOS Boot Menu key to trigger DVD drive.

Do you get a prompt to Press Any Key to boot DVD? If not, confirm your ISO integrity and burn another DVD using ImgBurn at 4x speed. Where did you get Win7?

Next try writing the confirmed ISO to flash stick using Universal USB Installer with Win7 in dropdown menu. Boot under USB, Removable or HD's.

Next try resetting BIOS to defaults. Then wipe the HD: SSD - HDD Optimize for Windows Reinstallation
