How to change Win7 as my default OS from Win8?

I had win7 on C:\ and I partitioned 25 GB so that I could install the Win8 90 day evaluation OS.
After the partition, I named the drive X:\ and installed Win8.

I never seen it give me an option to keep my Win7 as the default. It just restarted a few times during the installation.

When I turn on pc or reboot to see if it gives me this option to choose, it doesn't, it just boots into Win8.
Of course I can not delete this win8 partition because I am in it.

I need to get back to my C:\ drive with win7 on it and any help would be greatly appreciated.

Thanks,

Windows 8 is installed on C: partition. You have delete the Windows 7 install.

all my files for win7 are still on c: drive all my programs, doc., pictures.
Oh well ty thank you for replying.

Your Windows 7 folder is in Windows.old

Is there a way to delete win8 so that windows.old can be reinstated?
or is there a way to make win8.old ?

You can try this:
Windows.old folder - Restore into a new installation - Windows 7 Forums

Wow lucky me. I reinstalled the win7 cd and went to repair it said I had boot up issues and restarted then booted into win8 and it then asked me if i wantted to use win7 as the default OS. I said yes and it rebooted back into win7. lol lucky me.

This is what it should of asked me during the win8 installation I would of thought. Anyways all is not lost.
