How do I Lenovo BIOS Upgrade for Thinkpad E540 for Windows 7 from ISO CD?

2017-02-15, 19:37 PM

Please Help!

 

I ran the Lenovo BIOS Upgrade for Thinkpad E540 for Windows 7; it didn’t work. (“Failure to Read BIOS”)

 

So I downloaded the ISO version, and burned it to a CD. My laptop boots up ONLY from the CD.

 

Now exactly what do I do now, in simple instructions, to upgrade from the ISO CD to the new updated BIOS so that it would be on my laptop (instead of having to boot from the CD every time)?

 

Thanks!

Welcome to the forum!

 

If you boot from the CD (and the ISO was correctly burned on the CD), you only need to follow the instructions on the screen. If I remember correctly you need to press Enter once, (eventually confirm by pressing the "Y" key) and then the BIOS will be updated. After that you can remove the CD and boot normally.

 

You need to be connected to the AC and have a full charged battery before the update.

 

Hope this helps...

No. It didn't work.

The CD boots the laptop. Hitting Enter doesn't do anything, at any point, The boot goes straight to Windows.

How did you burn the CD? The ISO image must not be just copied to the CD, you need a program to properly burn the ISO to a CD, see an example guide here: Click me!

The ISO seems to have been burned onto the CD correctly.

However, it doesn't do anything but boot up the laptop.

What are the boot settings in the BIOS? When you press F1 after turning on your laptop, check the settings as shown below:

 

 

Under "Boot" you should set the CD at the top, something like this:
