Virtual machine not meeting Windows 11 system requirements, even though it should

I am trying to create a Windows 11 virtual machine on Hyper-V. I downloaded a clean x64 ISO from Microsoft. Here is my attempt using Generation 2 as a commenter recommended:

• Generation 2
• Default Switch
• 8192 RAM
• 128 GB hard drive
• UEFI Secure boot enabled
• TPM enabled
• DirectX 12 enabled

However, when I start the virtual machine, I get the following message:

I was able to get further using a Generation 1 virtual machine, before a commenter pointed out Windows 11 isn't supported in Generation 1. During those earlier Hyper-V new virtual machine setup wizard, I selected:

• Generation 1
• Default Switch
• 8192 RAM
• 128 GB hard drive

I can connect to the virtual machine and upon starting it the Windows installation kicks off normally. However, the installation process stops, stating that the machine doesn't meet the system requirements:

As far as I can tell, Windows 11 only requires 4096 RAM and 64 GB hard drive, which the VM meets. My host processor is also well above the requirement:

Can anyone help me understand why I'm getting this message during installation? Thanks for any help!

[Edit] Here is my attempt to verify some additional requirements mentioned by commenters.

• TPM. Following Option 2 of these instructions I was able to see this screen:

I don't know exactly what TPM is, but that seems to indicate the host machine has it enabled.

• DirectX 12 Graphics card. This was fairly easy to verify using these instructions:

• UEFI Secure Boot. Using these instructions, I was able to verify UEFI Secure Boot is enabled:

This seems to suggest all requirements are met.

Windows 11 isn't supported as a Generation 1 guest. You need to create it as a Generation 2 guest.

You mention RAM and disk space. However, the requirements list some more items:

• TPM
• UEFI boot
• DirectX 12 Graphics card
• Secure boot

You don't mention any of these items, which leads me to believe you haven't really checked the URL the error message provides.

Thanks to @joeqwerty I started using the Generation 2 setup option instead of Generation 1. I was getting an error booting, but that was because the Generation 2 setup assumes the ISO is on a DVD and not on a hard drive, requiring me to "press any key" when prompted to boot from DVD.

After in the Windows 11 setup, I was still getting the "requirements not met" error, however. Using another site where people are actually helpful, I was able to learn what I was doing wrong.

I had assumed that UEFI Secure Boot requirements were for the host machine. I didn't realize those were additional settings needed for the virtual machine after completing the new virtual machine setup wizard.

Someone explained that after creating the VM, I had to go into the security settings to enable these features (read-only because my VM was running when I took the screenshot):

Posting here in case another VM newbie has the same misunderstanding.
