Windows 7: Windows 7 clean installation question

Windows 7 clean installation question


I have 500 GB hard drive with 3 partitions. Windows 7 is installed on C: drive, 8.1 is installed on D: drive (dual boot) and all of my programs and files are on E: drive. I would like to uninstall Windows 8.1 and do a clean installation of Windows 7 without losing data from E: drive. Can I simply insert Windows 7 installation CD and format first 2 drives and do clean installation without losing data or do I have to format whole hard drive?

That is going to be a bit messy. I suggest to backup the User files from E (the programs cannot be used in a new installation) and start from scratch. Wipe the whole disk and install 7. Here is one way to do it.

When you are done with the installation, create a new E partition and recover the data from the backup.

You should always have your data backed up to begin with, against hard drive failure.

If you do and you want to keep E intact then I'd delete the other partitions and create a new on it their place. As long as you don't touch E you have nothing to worry about, providing you have a backup.

The tutorial Wolfgang linked above will assure you get and keep a perfect install for as long as you stick with the steps, tools and methods in it.
