Win 7 Error message

So I'm trying to upgrade from the 6801 build (32-bit) to the 7100 build so both my laptops are on the same build.... 7100 is way more stable also..

Anyways I put in my Win7 7100 DVD, restart the comp... I hit a key to boot from CD, it tries to boot and comes up with a screen that says:

"Windows boot Manager"

Error I/O

0xc00000e9

And I cant get 6801 off this comp. It's now starting be become unstable, it will blue screen and restart on my often......

I need help guys! Please!

What's goin on with my comp?

So run my 6801 in safe mode, put in my 7100, restart the comp while in safe mode, and boot from CD?

Oh and I'll take off all my USB connections....

This happened to me....a few times...and then somehow my HDD failed..

Ok so I tried taking all the USB connections off, and restarting from Safe Mode... No dice.

I have been having disc read problems. It won't read any disc. So I think I need to fix that and that'll fix my problem...

It's a HP zd8000 laptop, light scribe DVD-RW drive.... Any help with finding the drivers for it? Or ones that will work with the 6801 build of Win7?

That's what I'm trying to do. Booting from CD on startup.....

I used the same DVD on my other dv1000 HP laptop and it worked flawlessly... So that's what I'm not understanding...

I don't know where to find the right drivers for my DVD drive, and I don't know if it's my HDD that's failing... ???
