How to install exchange 2010 in an exchange 2003 environment!

To cut a long story short I started an install of 2010 remotely and then the 2003 server when down. When it came on i decided to reformat my 2008 server and redo exchange. However I kept getting an instability  error message and install wouldn't start so I decided to run adsiedit and go delete the administrative group that was pointing to the 2008 server. Install runs but now i get the message below. I just tried renaming my server to and running the install again and it still gives this error. I need some help please. My plan is to get this running so that i can decommission  the exchange 2003 that is already sitting on a server that overheats!

I finally got it!
I couldn't uninstall exchange so i had to manually uninstall it by stopping and siabling all exchange services, deleting the registry key values for the exchange +exchangeserver and then renaming the exchange folder.
Restarted the machine and then did a setup /m:recoverserver and then ran the schema and domain then installed exchanged.
The first error told me that the reg keys transport and then pickup weren't available.
All i had to do was create those keys manually and then it installed.
Thanks again for the input

Run Setup.com /preparead once and then try to install the Exchange.

I opened up the command prompt as an admin and navigated to the dvd drive and then ran the command setup.com /preparead
The command ran the unattended setup with no roles being installed.
The organization checks failed with the following message

A setup failure previously occurred while installing the Hub transport role. Wither run setup again for just this role, or remove the role using control panel
