So if the BIOS update does fail, you'll most likely need to have a USB flash drive using certain filesystem with BIOS image on it under a certain file name or have a CD-ROM with the image in your CD-ROM drive or have a floppy with the image. Instead a block which does he updating itself is either read only or updated once the rest of the BIOS has been updated to the point at which the computer can boot. Usually in modern BIOS updates, the whole BIOS isn't replaced at the same time. This way, if the update goes wrong, you'll know what to do. The most effective thing you can do is to familiarize yourself with the BIOS recovery procedure for your computer. I would also say, it is sometimes best to perform a settings wipe / go to defaults upon a flash and then change settings back just in case there are any conflicts or settings left over that have changed or similar. Changing it back after flashing made Windows boot normally. The reason was because my default setting was SATA Mode to IDE, when I had changed it to AHCI. In addition, a piece of advice as I just upgraded mine (GPU Voltage change, stops freezing!), Write down as many settings as you can, especially every one you changed. This being said, I have had power cuts and problems and sometimes it still works - there is no one answer fits all and it changes from manufacturer to manufacturer. If however you don't have this option, make sure you have access to another machine so that you can download a recovery image or emergency image (different names across different manufacturers) so you can do a recovery if needed. I would say, just go for it - some modern machines offer the ability to back up the BIOS and recover in the event of an error. I would say, if you are constantly having power cuts, don't do it - and on the same topic, it doesn't hurt to have a UPS on your machine as best practice, but it isn't worth getting one just for this! ![]() To begin with, I would say only upgrade if it is needed such as you have a critical problem or it offers something you need - if it just changes a logo or adds a feature you will never need, there is no point in doing it.īacking up really isn't an option on most, and when you upgrade, it could make the saved profile no longer work. Seriously, there isn't really a lot you can do.
