I have an older desktop PC from my previous employer that runs a company-installed Windows OS. I'm considering changing or replacing the hard drive; would that erase the existing OS image and let me install a new one? Also, if there's a BIOS password, will that block me from upgrading the OS? Are there any other options to avoid issues during the upgrade?

For a Dell like yours, it might be more complicated. Many companies do set BIOS passwords to restrict access, and if they used secure passwords, just removing the CMOS battery won’t help. If there’s a drive lock on the hard drive, you could run into issues when you try to wipe it.
It really depends on the specific model of your PC and how it’s set up. Some systems have ways to prevent booting from a swapped or wiped drive, especially if there are security features enabled.
Honestly, if this device is still managed by your previous company, I'd suggest returning it to them to properly remove it from their management system. Upgrading it without their consent could lead to complications.
Before diving into hardware changes, make sure your device isn’t still enrolled in your old employer's MDM (Mobile Device Management). If it is, even replacing the drive won’t help—the OS could revert once it connects online. If the BIOS is locked, it could get messy if booting from USB is turned off.
I’d recommend checking if you can reset the BIOS password using sites like bios-pw.org. If you manage to access it, that could open up some options for installing a new OS.
