Enabling VT-x in the BIOS of a G780

[lenovojim]

Hi

I've tried to set up a 64bit guest operating system in VMWare and in VirtualBox, but have been unable to. I understand that the problem might be that VT-x is not enabled in the BIOS. However, on booting up my G780 and using F2 to edit the  settings I don't see anything related to VT. 

Help appreciated!

Thanks

Jim

welcome to the community.

i always boot into bios by pressing F1. is it different for the g780?

if my memory serves, vt is listed under 'security' in bios. is that where you're looking?

cheers.

Thanks for your welcome, sarbin. F1 gets to the same place - the windows boot manager. Here I press f8 to specify an advanced option and the choices I have are:

Repair Your Computer

Safe Mode

Safe Mode With Networking

Safe Mode Wih Command Prompt

Enable Boot Logging

Enable Low-Resolution Video (640x480)

Last Known Good Configuration

Directory Services Restore Mode

Debugging Mode

Disable Automatic Restart on System Failure

Disable Driver Signature Enforcement

Start Windows Normally

But I don't see an option for Security.

When are you pressing F1?

On every Thinkpad I've had, F1 or Esc, pressed when the Thinkpad splash screen is visible has taken me to bios, not a boot manager. I'm not at a pc right now, but when I'm back a bit later I'll see if I can find out if the sequence is different for a G780.

Please bear with me.

Cheers.

Hi Sarbin. I have the F1 or other function button pressed down as the system is rebooted. There doesn't seem to be any other time I could press it.

I'll wait and see if you come up with anything.

Thanks

Ok, I've confirmed that you need to press F2, as you were doing previously, during startup to enter the BIOS. You should be pressing it when you see the Lenovo splash screen appear. Maybe you weren't pressing it at the right time? I've also found that pressing a couple times while the splash is showing works.

Here are a couple documents I found that may be of use to you as references:

User guide - http://www.lenovo.com/shop/americas/content/user_guides/gseries_ug_en.pdf

Hardware maintenance manual - http://download.lenovo.com/consumer/mobiles_pub/lenovo_g480_g485_g580_g585_g780_hmm_v1.0_english.pdf

Quick question... what CPU is in your machine?

Cheers.

ETA: looking through the user guide linked above, on page 47 at the bottom, it says

   "Hold F2 during startup. The BIOS setup utility screen opens. The
    System Memory item shows the total amount of memory installed in
    your computer."

So, if the method at the top doesn't work, try this: Shut your machine all the way down. Press power. Press and hold the F2.

This is certainly different than what I'm used to with my Thinkpad Ts, Rs and Xs.

Sarbin, this time I powered off the computer rather than using restart, and kept the F2 key pressed down. This worked and I had the BIOS settings screen! The VT setting was under configuration rather than security, but was easy to find. I set it to enabled and have now installed a 64bit guest virtual machine. Many thanks for your help and suggestions.

Have a great day!

great!

i should have asked if you were doing a restart or a cold start. getting into bios alway requires the latter.

glad it's sorted out. happy computing!

cheers.
