Dsktop w/EISA can't boot from CD,NTLDR missng

Specs: Windows Vista, 4GB
My Lenovo Athlon 64 desktop came with Windows XP Home installed on a drive that has the EISA recovery partition. Later I installed Vista Home Premium on two other HDDs I have in the desktop. Now in order to do a clean install of 64 bit Windows 7, I need to clean boot the system from the Windows 7 installation CD, but my desktop won't boot from CD/DVD RW drive. Here are the settings I tried out and the results I got:

1. Changed BIOS startup sequence to have the CD drive first follows by the primary HDD (containing XP which is on the disk that has the EISA): the CD light comes on at bootup and it starts spinning but then the light goes off and system shows the normal bootup screen showing all the 3 OS's available to boot from and asking me select one.

2. Removed the primary XP drive from the BIOS startup sequence so that the CD is the only drive there: now upon bootup again the CD lights up and starts spinning as earlier but then I get "NTLDR is missing, press ctrl+alt+del to restart"

I have tried the Windows 7 CD on another laptop and that booted fine and showed me the Windows 7 install screen - so the CD is definitely bootable.

I opened the box and verified all jumpers, cables etc.
- The primary drive with XP is connected using SATA, and so is one of the HDDs with Vista.
- The other HDD with Vista uses IDE cable 0
- the CD/DVD RW drive is on the other IDE cable

I checked out another post on this forum that seemed to pertain to a similar issue - but I think the scenario was slightly different.

What do you think is the problem here? Is my CDDVD drive bad i.e. unbootable? Or is the EISA partition the culprit?

A quick followup - someone suggested I try inserting the Windows 7 32 bit CD instead of the 64bit CD. I didnt think it would make a diff, but I tried anyway. It didn't make a difference.

Please help. Would love to hear your thoughts.
