I have an HP Elitebook 8560p with Windows 7 Pro 64 bit OS however when i tried to upgrade it to Windows 8.1, it won't detect the hard drive to install the new OS and it is aking for drivers or to load drivers. I think the drivers for the hard drive had been corrupted or damaged. I tried to setup the BIOS howver it is asking for Admin password which in the first place i did not setup.How can i fix this issue and used my HP laptop again, Can you kindly assist or enlightened me. Thank you.
Welcome to HP Support Forum and we are glad to assist you.
This is to inform you that all HP Business Notebooks such as Probooks or Elitebooks have more stringent security than consumer models infact they don't produce 'halt codes', the password cannot be derived from the Serial Number and the
code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.
