I upgraded Windows 7 Home Premium x86 to Windows 8 Pro x86, and I was wondering if it was possible to restore back to Windows 7 using the restore partition.
Once you have manually installed the OS and/or changed partitions the internal restore partition usually no longer functions.
You will likely need to clean install follow my Windows Reinstallation Guide/A Clean Install of Windows 7.
Thank you, your guide is very helpful!
As far as I know, I haven't changed the restore partition at all, unless it was changed by the Windows 8 installation.
Normally it doesn't work when the OS is upgraded or manually installed.
Installing the latest version of Dell Backup and Recovery may help you however: http://www.dellbackupandrecovery.com/en-us/Index.html
Its meant to have some fixes over the previous version of software. If it can access the recovery partition you may be able to use it to create a bootable USB recovery media to restore to factory settings.
