I have an OEM Toshiba A500, came with Windows 7 Installed, I did not made the recommended recovery DVDs, as I never used them before. The HDD came partitioned into two drives C & D. A few months ago I made a new partition from the D drive and installed Windows 8.1, as dual boot. Now I uninstalled Windows 8.1, and returned the D partition back to its original size. During this operation I did not use any third party application only used the built in Windows disk manager. My question: Does this ruined the factory recovery built in? I recall reading somewhere that if the OEM hard disk partitions changed the factory recovery will not work, and is it possible to make the recovery DVDs now? I would appreciate any help very much.
