I am not sure but I fear that installing W7 RC over the top of Vista may have deleted that hidden partition, or the access to it.
If F11 is the normal method for accessing this hidden recovery partition but that doesn't work, then your next step is to contact the computer's maker/supplier, and ask for the Vista install disk and drivers disk. They will charge a small fee, but then you have pristine disks to retain for future use on this system.
I have a Hp Pavilion dv4 with a windows vista recovery partition, but i installed a windows 7 Release Candidate, i bought windows 7 for my other computer thinking i could install it on more than one, anybody know how i can access the recovery. I cant do it on startup f11 doesnt do anything.
