Hi folks - having read all about the Meltdown & Spectre risks, I have downloaded the MicroSoft update for Win7.

On the Dell site, I have read about updating my BIOS, & have downloaded the correct BIOS update file. The instructions say I should "Run the BIOS update file from within Windows". Or, "Run the BIOS update utility from DOS environment if Legacy Boot Mode".

My BIOS is Legacy Boot Mode, but is it OK to still run the update file from within Windows? But, because my PC is now a few years old, is it even worth trying this update?

I'm extremely nervous about updating the BIOS, in case it goes wrong & I'm unable to run my PC ever again. Please can you experts advise?

I'd very much appreciate your help & advice. Thank you.

Kind regards, Niloc1017
