Windows 7 How to remove one Win 7

[wondy]

Hi.

I had a electricity fail in my house during instalation of win7.

So I reinstaled it, formating disk once again and now I have TWO Win7. The secon one does not work.

How to delete one?

The computer asks me which to chose every time I Turn it on.


EDIT:
I have one strange partition 100MB:/ It was created by win7? Jutro format it and there will be one win7?

The 100 MB partition contains the boot files.

Go to Start, Run,. and type msconfig,. click the Boot tab,. leave the default and delete the other one.

Noe look in Disk Management t see if the partution is stil there.
