I have a compaq laptop that has a big problem. When turned on it instantly says 'BOOTMGR missing / Press ctrl+alt+del to restart' but this isn't directly the problem i need solved. to fix this i need the recovery disc or instillation disk for this laptop which i do not have. I tried to get an iso from the microsoft website but it said
'The product key you entered appears to be for software pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options.'
So my problem is i need to get the correct ISO from Compaq/HP for this laptop, i just cant find it. I cant get much information about the specific laptop because i don't have any manual for it and any sicker that may have given information are not on it, All i know is that It is windows 7 home premium (i think 64 bit, sticker is faded), it has a Pentium processor, and the license sticker says HP (it is a compaq laptop but i am lead to understand that it is one and the same.) If you have any insight into how to help, any input is apreciated.
(also, is it possible to determine the exact version from the key alone because the sticker is faded and i am not 100% sure on the version)
