Make a Recovery USB with the latest version of Dell Backup and Recovery and reinstall from it: [URL] I would however recommend downloading a Windows 8.1 .iso and performing a clean install: [URL] [URL]
I recently used the recovery partition to reset my laptop. I was using 8.1, was reverted to 8, then I did the upgrade to 8.1 again. I'd like to recover to the original factory condition again, to start over.  I've learned there may be troubles using the recovery partition. Is that true? If so what solutions are available? I didn't have problems when I did so a few days ago, but I'm reluctant to tempt fate. Basically I'm afraid of being left with a laptop that is unusable. I believe I made an install disk at some point and will look for it. Maybe that is a solution?   Inspiron 5537 purchased almost exactly one year ago. 6 GB ram 64 bit system Intel Core I5-4200u @ 1.60GHz  Thanks for any and all help.  Darryl
