If the recovery key is not known this can result in data loss or an unnecessary operating system re-install.Your computer's BIOS - Basic Input/Output System - is a chip on the motherboard which contains enough information to allow it to start up before the main operating system begins to load.Here’s how to check what BIOS version your computer is using and flash that new BIOS version onto your motherboard as quickly and safely as possible. If your computer freezes, crashes, or loses power during the process, the BIOS or UEFI firmware may be corrupted.This will render your computer unbootable — it’ll be “bricked.” Your computer’s BIOS version is displayed in the BIOS setup menu itself, but you don’t have to reboot to check this version number.If there's a power cut, or the computer gets turned off while updating, it could mean that it's unable to boot at all.For this reason, it's worth checking whether you really need to update your BIOS.It is in charge of that memory counting that happens every time you turn on your PC.And setup is that program that you run by pressing Del during POST (i.e., during memory counting) that is used to configure your motherboard.

If not, there may be little point in taking the risk by updating.If your Dell PC or tablet supports BIOS recovery, you can recover the corrupt BIOS by using the BIOS recovery method on your Dell PC or tablet.Refer to the Dell knowledge-base article BIOS Recovery options on a Dell PC or Tablet for more information.To locate other BIOS versions you can try and find the version download by navigating through the links located at Caution: If Bit Locker is not suspended before updating the BIOS, the next time you reboot the system it will not recognize the Bit Locker key.You will then be prompted to enter the recovery key to progress and the system will ask for this on each reboot.
