Hello, thanks for reaching out. I'm Ace, one of the Independent Advisors. I can understand your concern and please don't worry I am here to help you.
If you're encountering the E_INVALIDARG error while installing Ubuntu on WSL2 in Windows 11, the issue is likely related to virtualization settings, Hyper-V, or a corrupted WSL installation. First, check if Virtualization Technology is enabled in your BIOS/UEFI settings. Restart your system and enter BIOS by pressing the appropriate key for your Dell machine, such as F2, F10, DEL, or ESC. Navigate to the CPU configuration section and ensure that virtualization is enabled. Next, verify that Hyper-V and Virtual Machine Platform are installed and enabled. Open Windows Features by searching for "Turn Windows features on or off" in the Start menu. Ensure that both Hyper-V and Virtual Machine Platform are checked, then restart your PC. If the issue persists, resetting WSL may help. Open PowerShell as Administrator and run the following commands: wsl --shutdown, wsl --unregister Ubuntu, and wsl --install Ubuntu. This will remove and reinstall Ubuntu, potentially resolving any configuration issues.
Let me know if this method works.
Thanks!
