Recently, I was asked if there was a way to extend the boot time to give an end user time to access the BIOs because they needed to make changes to the config. It has been a minute since I have had to do this so I thought I would write a refresher blog with two methods.
Method 1: Change the boot delay which causes the VM to not boot as fast allowing more time to access the BIOs.
Method 2: Force BIOs setup, which forces during the next boot to access the BIOs
Method 1 – Change Boot Delay

Right click on VM or click actions and go to Edit Settings

Go to VM Options > Boot Options
Here you can change the Boot Delay to give the user more time to access the BIOs.
Method 2 – Force BIOS setup
You get to this section following the same steps as below. The only difference is you want to check he box net to Force BIOS setup, which during the next boot, force entry into the BIOS setup screen.

Summary:
Not a long or difficult process to follow. Now if you are performing a large deployment I would recommend to script it but also remember to go and change everything back if it is no longer a requirement post install. As always, I hope y’all found this article useful.
