the Disc type must match the COA used,
However, there may be something more to this:
- is the COA sticker a normal rectangle shaped OEM (Dell) Branded COA?
or
- is it one of the funny shaped ones that come with a Retail or Upgrade Disc?
if Retail or Upgrade, then you will need one or the other of the particular type of install Disc
if OEM branded COA then an OEM Disc is required.
There are two types of OEM recovery Discs:
# 1 - Restores the OEM VLK install with all the drivers and the bloatware
- no activation required
# 2 - is an OEM (usually modified) re-branded standard OS install Disc
- which uses an OEM COA key activation normally required and usually the install checks for something specific to verify the system is one of theirs
Dell checks the BIOS
- these won't accept any Key from a Retail or Upgrade COA
just as Retail and Upgrade Discs won't accept OEM COA keys
etc.
every Dell Disc I've seen from win2K RTM to XP SP3
is the second type (Re-branded OEM OS Install Disc that only install on Dell systems)
and the recovery set shipped with the system have drivers and apps on separate Discs
The only recovery Disc I've seen that matches # 1 was for a Toshiba Satellite
Recovery partitions tend to be the same as # 1
- restoring the VLK install with drivers etc.
Now here's the rub:
if the COA is an OEM Branded and was pinched and then used on another system
which happened frequently with XP, as people would copy the COA key from systems in stores, warehouses and even systems in use in offices etc. and then use the Key(s) to install on different systems
as every major mfg. use a VLK for pre-installed systems and the OEM COA is unused
also, because OEM System Builder "For Distribution Only With a New PC, or required hardware" OS install Discs use the same COA subset as the OEM branded OS install / re-install Discs,
- means an OEM System Builder Disc will accept and activate with Big Box (HP, Dell, etc.) OEM Branded COA Keys
an OEM branded Disc usually will not work on a different brand
eg.
A Dell branded OS Disc will only install on Dell systems, and can't be used to install on an HP etc. but may very will accept the OEM Branded COA key from the HP etc.
I've used a Dell Branded Disc on a Dell with the unused COA from an HP
if you have access to an XP SP3 or even SP2 OEM System Builder Disc
you can install with that and use the OEM COA on the system,
however, if it fails to activate that may indicate that the key was pinched and used on another system with the probability of 0 matching hardware
OEM COA Keys generally work over and over again on the same system if most of the hardware is the same especially specific key components such as the MB and Processor
and the installs are not too close together
but will usually fail if used on a completely different system,
which will usually require a call to MS to explain why the hardware doesn't match anymore
and hopefully they accept the reason(s) and allow the activation
