HP Elitedesk 800 computers are annoying.

These computers are very annoying to setup. You have a VGA monitor connected and there is sometimes nothing displayed on the screen until Windows boots up. But if a Display Port to VGA adapter is plugged in, then you can get a picture. Why does this happen? And the VTx virtualisation extensions in the BIOS were not enabled by default, I had to go to each machine and configure that setting. This should be on by default. There will be people using these machines that will need VMware or HyperV and it is annoying to require manual configuration for every single machine. This setting BTW is under Advanced->System Options and the options are halfway down the screen. These machines are not bad with 32 Gigabytes of RAM and Windows 7, but having essential functions switched off by default is strange. I like the ability to use the mouse to navigate the UEFI BIOS setup screens, this makes it far more usable. If the graphics card is installed to the first PCIe slot, it does make sense that it would take over from the integrated VGA port and become the main graphics output, it is just annoying when there are only a couple of Display port adapters and you need to plug it into one machine after another to configure various settings in the BIOS.

I prefer to use legacy boot on my home PC, it gives me much more time to access the BIOS/UEFI settings if needed without putting up with fast boot. I am not sure if GRUB2 works with UEFI fast boot or not, I have not tried Ubuntu with secure boot at all. Apparently Windows 7 does not work with Secure Boot, that is why I will stuck with legacy boot for a while. Some people are opposed to Secure Boot, they see it a freedom denying technology and prefer the legacy option. I am one of them. Only if you are using Windows 8 or 10 is Secure Boot actually usable. But Windows 10 is too new to be worth upgrading to yet. Microsoft are trying to force users to upgrade to Windows 10, this is very suspicious. Windows 7 is supported until 2020, better to run that instead. Windows 10 does not run very well on a laptop with 6 gigabytes of RAM compared to Windows 7. And it is supposed to be better? The display port connector can carry multi-channel audio as HDMI can, this is good for connecting a TV to a PC as a monitor and getting HD sound with no noise.
