All you can do in the BIOS is select which device to Boot from and some of these newer systems have an option to Secure Erase (Wipe) a SSD. Secure Erase works on the Binary level in which it causes all cells in a SSD to reset to 0. So if your system supports Secure Erase and you have a SSD, You can Erase the SSD then reinstall the O.S. Or maybe you can force the system to boot the O.S. on another drive.
If you have Windows 10, you can download a copy of the O.S. to either a Thumb Drive or a blank and unformatted DVD using the Media Creation tool. You can also use the Media Creation tool to download Windows 7 but you need to enter your Product Key number prior to downloading the Software. Using the Media Creation tool to download and burn Windows 7 is known to not work on OEM product keys. These are fresh copy of Windows which has the drawback of you having to download all the drivers for your system.
With a name-brand PC, there is usually a recovery partition that will reset the system to it's factory settings with all the drivers and bloatware installed. nYou have to rapidly press keys like F9, F10, F11, Ctrl, etc unless you know what it is. Lenovo systems have a little hole next to the Power on button that lets you access the recovery partition and BIOS.
