|If you do a standard system recovery routine - be it via the "hidden" partition on the drive (at the physical start of the drive) or via a recovery disk itself... All previous restore points will go...|
Which is perhaps one reason to make your own restore/recovery disks too - with all "your" additions etc. in the version. Typically one will use a third-party util to this end (and crate an image of the drive/partition as you like it to be); I favour Acronis v.11 - although there are many others out there as well...
Also some laptops etc. have a built-in util to make a recovery set when you get the kit new (Acer have one for example); and that can be run as often as one wishes to make more current recovery disks that incoporate "your " adititions again as above?
Also "some" recovery routines allow a sort of half-way restore; essentially repairs etc, to some degere the installation - but doens't atack/destry data. But again I think all previous restore points will go... There is usually a "menu" of sorts to allow you to "choose" what you wish to do...; but not always?
Certianly I wouldn't bank of any restore points surving a typical restore/recover routine.
An (bootable/restorable) image (e.g. made via Acronis etc.) will probably preserve any Restore Points in existance at time you make the image? But not having checked that bit personally... I'm theorising...
So overall I suggest it's - yes all previous restore points will more than likely go when run a recovery/restore routine.
