Windows 7: Failed install windows7 home to windows7 enterprise

Failed install windows7 home to windows7 enterprise

I have an HP Compaq dx2000mt desktop that has windows7 32bit enterprise installed on it. I tried to install windows7 home 32bit to replace the enterprise OS. As I was installing it stated the old OS would be marked, XXX.old and it went forward, then came to a point where there were booting errors. and it stopped installing. Now I am left with a half install, and a full OS the boot section now in its own drive named disk 0 system reserved.
I partioned the C drive and allocated 20gb and tried to install there. I received the same errors seems that my boot.ini is stuck in the system reserved and I cant figure out how to incorporate disk 0 over to disk C, so that my boot is in the same disk drive.
I have really messed this one up. I have installed an operating system before and never had so much trouble.
Any advice would be helpful.
And please if you have an answer, something for me to do, it needs to be A.B.C.'d out step by step as Im not an expert. But I guess I already proved that...
Thank you in advance.
Katz

Thank you very much for the instructions. I am still getting an error OxcOOOOOOe
The installation was in full then on reboot that is where I got this message and that the installation was rolled back and my current version was back.
I dont have any of the disks on the win7 enterprise that is why Im trying to install win7 home instead so I will have the disks.
I am trying to use a new volume I named E: I formatted it before install and all went well up to the reboot as Id stated.

You'll need to boot the installer and if you continue getting the error showing it's instead trying to boot the hard drive, replace the installer with the one provided - using the tool provided to burn to DVD or flash stick.

That is all from the remains of your old failed install. Do you want to repair that install or reinstall? To reinstall you must boot the installation media, delete all partitions and proceed with Clean Install Windows 7.

If you want to repair the present install work through Troubleshooting Windows 7 Failure to Boot

I found that if I took out the bootable USB during reboot while installation was taking place, that it finally installed. So now I have duel OS. One windows 7 enterprise and the other the new install win7 home, to which I did down load from the links here, and thank you very much for that. I did already have it from where I purchased it, but it was just nice to know it was a fresh install.
So my next thought is can I now delete all I can on the enterprise and reallocate most the gb over to the new OS.

You can avoid having the installer autostart like that by setting HDD to boot first, trigger USB stick using Boot menu key at boot.

After you've moved everything off Enterprise post back a screenshot of Disk Management - Post a Screen Capture Image and we will give you the steps to remove Enterprise which probably still has the System boot files for both OS's, to Recover Space Used by an Older OS .

Because you ran the installer from OS instead of correctly booting it The new OS will not boot as C. I would do it over and this time follow Reinstall tutorial below.

If you have everything off the old OS then delete all partitions during install.
