They do vary, and you may need to configure some things before starting the update process, such as disabling secure boot modes and fast boot modes.
If a BIOS update is indeed among them, it‘s time to check the numbers: Did you type in the name of your mainboard correctly? And if so, does it state that your specific problem will be addressed in the documentation?
If everything applies, upgrading your BIOS is likely a worthwhile idea.
Even if the BIOS update is designed to be run from a floppy disk you can usually use a USB flash drive, but you may need to first enter the BIOS to tell it to boot from the CD or USB drive instead of the hard drive.
Typically you won't need to as a PC or laptop will be set up to look for a removable disc or drive before trying to boot from the hard drive.
Though a failed BIOS update doesn't endanger the data on your hard drive directly, you will be able to access your files and continue working with them on another PC or Laptop without delay if you have a backup on a removable drive.
Similarly, creating a backup of your BIOS is also a good idea.Sometimes this will be done automatically as part of the updating process, but if it requires you to do it manually, be sure not to skip this step.The easiest way is to look in the user manual of your mainboard.Plus, you should note down the revision number – for example REV 1.03G as it may require a different BIOS file to previous revisions.If you have a laptop, you need only to find the make and exact model of the machine itself.See also: How to install Windows 7 Before you start, heed this warning: if something goes wrong during the BIOS update, your computer could be rendered useless.
