No factory image restore button

The partition is damaged so its broken forever.

No it isn't, they said the FACTORY.WIM is still there. I'm betting the problem is that they have manipulated the OS Partition and made it the Boot Partition rather than the Recovery Partition (SOP, always the Bootable one, where the REAL BCD Store is). Still, they'll need an Install DVD to fix it (pretty easy to do). This information on how-to is all over the WWW ("format" then "imagex apply" then "diskpart" to ensure Recovery Partition is the Boot). The WINRECONFIG.XML for the "missing" entry (it points to the Dell Recovery Program, of which several variations exist) is in the Recovery (Boot) Partition, either in a "Flat" WinRE-type setup or in the WinRE.WIM (depending on how Dell set it up). If the OP hasn't "wiped out" the Disk (which would have possibly wiped the RECOVERY partition irretrievably) then it's possible to Recover properly. Let's see if they come back? Side note: Always a bad idea to say "Wipe the disk and reinstall". Too many people say that and it's flat wrong. Your suggestion to get the "latest one" isn't a bad idea BUT you can ONLY get Professional (I have it) as they no longer provide any other Downloadable Editions. (BTW, they're Multi-Language Dual-Layer Monsters.)

Followup to clarify: https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/add-a-custom-tool-to-the-windows-re-boot-options-menu Browse your own RECOVERY partition VERY carefully to see what I mean. Hope this helps
