I'm running XP Pro on my Toshiba laptop that I'm going to upgrade to Win 7 very soon.

The laptop came with Vista pre-installed but had a downgrade option to XP Pro which I exercised. There was no installation media, just a recovery disk builder which if memory serves me correctly I used to burn both Vista and XP recovery/installation disks.

I'll be purchasing a retail Win Pro 7 Upgrade.

According to this page under Currently running Windows XP

Customers with Windows XP can purchase Windows 7 Upgrade versions but must back up their files, clean install, and then reinstall their applications.

I have no other option but to do a clean install (fine by me).

During this clean install will the Win 7 installer ask me for my original media? If so will my burnt recovery disks satisfy the requirement?

No, my understanding is that it will check the hard drive for the existence for the previous version of Windows and act accordingly.

I believe you'll need to start setup from within Windows XP.

Here is a guide detailing the process.

In that case I wonder what I would do if later down the track I needed to do a clean Win7 install due to hardware failure or virus infestation? I couldn't start it from inside WinXP then. –  LachlanG Oct 22 '09 at 3:55
    
@LachlanG: What about taking a backup disk image of your XP install first using Symantec Ghost (or a free equivalent)? –  Umber Ferrule Oct 22 '09 at 11:50
    
Unfortunately I don't have a way to test that, hopefully someone who has knowledge can drop an answer. –  Joshua Oct 22 '09 at 13:54
