Houzaifa, i commented on your other thread here...
I'm not sure what type of recovery method is used on your system but there many types of recovery methods used by HP/Compaq and other OEMs.
But when an OEM provides a recovery partiton on a HDD, the F-key recovery process requires an OEM boot sector to be placed on the HDD (and not the standard MS boot sector).
So if you re-install Win7 using a Microsoft Win7 install disk, the build process will not re-create a recovery partition (as the MS install disks know nothing about such recovery partitions) and the build process will write a standard MS boot sector to HDD (so even if the recovery partition was not wiped from the HDD, you couldn't access it using the F-key).
In some cases the OEM may also provide special tools to make a recovery disk from the recovery partition but when restoring from such user made recovery disks, their process may not recreate the recovery partition or OEM boot sector.
Your best approach is to not worry about the missing recovery partition but if it does bother you, call HP support and see if they can clarify how you can rebuld your system to as factory delivered (which includes a recovery partition and the associated bloatware).
But to get clear help on these forums you need to be very specific on exactly what you have done/tried/used. Your first thread was unclear as you indicated you replaced the motherboard and then F11 would not work BUT you did not indicate you also replaced the HDD... And in this thread you are not clear what type of recovery disk you used (MS Win7 install disk, HP recovery disk, user made recovery disk via HP tools, user made recovery disk and system image using Win7 Backup & restore, etc).
Clarity helps...
