I don't see some of the photos. Probably the ones where the date and time was showing. Is it still correct (the date and time)?   Otherwise I don't see why it should not work. Perhaps it was installed using a different setting for SATA Opeartion. Maybe it was set to "LEGACY" back then when Your Windows was installed? I assume You have important personal data on the drive. If everything fails You should disconnect the HDD and install Windows again on another HDD or SSD and after that connect Your old HDD to the SATA 2 port and save all Your data from it.
Hi, I'm new to this form and would appreciate any guidance offered.  I have an old, refurbished Dell Optiplex 755 Bios version A-10 4-30-08, running Windows 7 Professional.  I turned on the computer to find that the battery was dead. I replaced it successfully, but upon starting, I encountered a "windows failed to start" error.  I launched the startup repair as suggested which failed. After doing a little searching, I think I may need to reset the Bios but have no idea how to do this or which components to change.  I was able to change the date and time correctly, but beyond that, I'm lost.  I'm not very computer savvy, and I am not familiar with a lot of these terms that I'm reading about, so I'm a bit unsure as to how to proceed.  Any guidance would be greatly appreciated!  Thank you!!
