We strongly suggest to install Windows 8 on a new partition rather than installing it on the same partition you were using for Windows 7, else you will be unable to boot Win7.
Tip: If you accidentally installed both OS’s on the same partition, I suggest to open C:\Windows.old and check for any old files you may want to backup
