I'm trying to breathe new life into an old company laptop (a Dell Latitude 5430) for a friend. It's currently locked with a BIOS password that I can't reset because I can't contact the previous manager who set it up. The laptop can boot into its old Windows installation, but my friend wants to replace the hard drive and start fresh with a new Windows install. I've tried a few things:
1. I looked for default BIOS passwords specific to my laptop model, but none worked.
2. I tried resetting the CMOS battery, but it seems ineffective since the settings are probably stored in the TPM.
3. I attempted a USB install of Windows, but I ran into issues selecting the new M.2 hard drive due to driver recognition problems, likely related to GPT/MBR/ACHI settings, which I can't change without access to the BIOS.
4. I even tried installing Windows on another computer first, but then I got an INACCESSIBLE_BOOT_DEVICE error when I booted the laptop.
I'm feeling stuck! Is there any way to bypass the BIOS password, or am I just out of luck? This laptop is taking up space on my desk, and I'd love to get it sorted out!

If your goal is just to watch movies, why not install a lightweight Linux distro like Linux Mint or FlexOS from a USB? It could save you the hassle of dealing with Windows altogether!
Laptops are a real pain when it comes to BIOS passwords! If resetting it isn’t an option, you might want to try a brute force attack with common passwords. It’s a long shot, but you could get lucky! Think typical passwords like '1234' or 'password1'.
I've had some luck in the past. On an older ThinkPad, I opened it up and found the EEPROM for the BIOS password. By shorting some specific pins, I managed to reset it—but that was quite a while ago, so I don’t remember the details!
If you still have the original hard drive, consider cloning it to the new drive. You might hit some activation issues since the board is already linked to an active license key, but it could work!
That sounds like a solid plan! Just be sure to keep the old Windows installation intact and clear out any personal data you don’t need.
