Windows 7 - Windows 7 2 installations

I have installed a retail version of windows 7 and for some reason when i boot now I have an option to select windows utimate and windows ultimate recovered .Any one help with the best way to remove this please,Its my old beta version

Boot up question

Its not listed under boot in msconfig, just the windows 7 im using

Oh, that's easy: Run a Startup Repair. That should take care of it immediately. If you don't know how, boot from the installation/repair disc and select "Repair my computer". It's self-explanatory from there.

Thanks for the help, I have got to the stage where both windows 7 installations are showing on the boot tab under msconfig,theres no option to remove the second O/S as the delete tab is greyed out. The 2nd windows 7 is on the d drive, this laptop has 2 drives.Ideally I want to delete windows 7 on d drive and install xp pro for some car diagnostic software which only runs on xp,Is there an easy guide how to do this..I have read Dual Boot Installation with Windows 7 and XP but need to uninstasll this installation on d drive

Did you run a Startup Repair?

OK latest, I dcided to format and install xp pro on d drive and leave windows 7 on c drive.When i rebboted I only had the option to run xp pro so then run a windows 7 repair.now I only have the option of windows 7 Think I will stick with fixing cars
Is there any way I can get both O/S on a dual boot please

When you installed XP, it didn't know how to configure the dual boot with Windows 7.

When you ran Startup Repair on Windows 7, it only concerned itself with recovering Windows 7.

To recreate the Dual Boot, download EasyBCD and add XP back in using the Add/Remove tab, choosing type shown, name and correct drive

Thanks for all the help all sorted and running correctly now
