I would not think that Dell disks...would work on a system made by a different OEM. That would be a violation of the license which Micrsoft has assigned to Dell, IMO...since such a disk would then be equal to a MS Genuine Windows disk (sold by Microsoft as a retail item).
FWIW: There was a time (prior to 2005) when Dell CDs/licenses were sold the same as MS Genuine XP disks/license...but Microsoft put an end to that era.
Dell restore/recovery disks which work on Lenovo laptops...would also be something Lenovo would be concerned about, IMO.
Could you post the source of this reference, please? It's possible that you misinterpreted/ignored the context of the wording.
FWIW: Windows has never issued an error message stating that a file has been "desroyed", to my knowledge. The wording will only indicate that a system file is either missing or corrupt/damaged, IME.
