General Step by step with screenshots here for making FULL SYSTEM IMAGE image using Macrium Free
Create drive images with Macrium Reflect to easily restore a PC
You must make recovery media on a flash drive from within the software in order to be able to restore an image. This recovery media can also be used to make a backup offline in a computer that will not boot. Therefore, if your computer will not boot in normal mode, Macrium can be installed on another machine, make your recovery media there, then boot the troublesome computer from the recovery media and make your backup. The same recovery media is used to restore the entire system image
or a partition within the image. (In your case this would be your data partition)
Note: To restore ONLY files and folders within the image after a clean install, you can install Macrium, browse the backup in explorer, and copy and paste files/folders from the backup into a newly formatted machine.

@zbook can I backup to a USB stick using the "create system image" control panel backup procedure for windows7?
That method is not advisable. Use Macrium or another reputable backup solution
You must understand something here.
If a repair install does not fix your problem and you have to resort to a clean install, in your particular case, you are interested in recovering only your data partition since your OS is corrupted.
A clean install of Windows has to be done in contiguous unallocatted hard drive space. If your current data partition now resides at the end of the drive, this is not a problem. But if it's not, you will have to do some manual repartitioning. Without seeing a screenshot of your disk management screen, I can not advise what you will have to do to accomplish this if it becomes necessary.
