How to fix this PC can’t run windows 11?

The error “This PC can’t run Windows 11” typically appears during Windows 11 installation in a virtual machine (VM) or on physical hardware when the system doesn’t meet Microsoft’s minimum requirements: a compatible 64-bit CPU (e.g., Intel 8th Gen+ or AMD Ryzen 2000+), 4GB RAM, TPM 2.0, Secure Boot, and 64GB storage.

In a VM like VirtualBox on a Mac (as per your earlier context), these checks can fail due to missing hardware emulation (e.g., TPM, Secure Boot).

Below is a step-by-step guide to fix this by bypassing CPU, RAM, Secure Boot, and TPM checks using the LabConfig registry method and other tweaks, tailored for VirtualBox on a Mac host : –

Prerequisites

• VirtualBox VM: Set up with Windows 11 ISO attached (see earlier steps if not done).
• Windows 11 ISO: Downloaded (x64 for Intel Macs, ARM for Apple Silicon—though ARM bypasses differ slightly).
• Mac Host: Intel or Apple Silicon running VirtualBox 7.0.x.

Step-by-Step Fix to the error “This PC can’t run windows 11”: –

Step 1: Start the Windows 11 Installation

• Boot the VM:
• In VirtualBox, select your “Windows 11 VM” > Start.
• Boot from the Windows 11 ISO (press any key if prompted).
• Encounter the Error:
• Proceed until you see “This PC can’t run Windows 11” (usually after selecting Install Now).

Step 2: Access Command Prompt in the Installer

• Open Command Prompt:
• At the error screen, press Shift + F10 (or Fn + Shift + F10 on some Mac keyboards).
• A Command Prompt window opens.

Step 3: Create LabConfig Registry to Bypass Checks

• Launch Registry Editor:
• In Command Prompt, type: regedit
  • Press Enter to open the Registry Editor.
• Navigate to LabConfig:
• Go to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
• Right-click Setup > New > Key.
• Name it LabConfig.
• Add Bypass Entries:
• Inside LabConfig, create these DWORD (32-bit) values:
  1. BypassTPMCheck:
  • Right-click LabConfig > New > DWORD (32-bit) Value.
  • Name: BypassTPMCheck.
  • Double-click > Set value to 1 > Base: Hexadecimal > OK.
  1. BypassSecureBootCheck:
  • Name: BypassSecureBootCheck.
  • Value: 1 > OK.
  1. BypassCPUCheck:
  • Name: BypassCPUCheck.
  • Value: 1 > OK.
  1. BypassRAMCheck:
  • Name: BypassRAMCheck.
  • Value: 1 > OK.
• Result:
• Registry should look like: “` HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig
  • BypassTPMCheck = 1
  • BypassSecureBootCheck = 1
  • BypassCPUCheck = 1
  • BypassRAMCheck = 1
    “`
• Close Registry Editor:
• Click File > Exit.

Step 4: Resume Installation

• Return to Setup:
• Close Command Prompt (exit or click X).
• Click the back arrow in the installer (top-left) to return to the previous screen.
• Click Install Now again.
• Proceed:
• The installer should now skip the checks and let you continue.
• Select Custom: Install Windows only (advanced).
• Choose your virtual disk (e.g., 64GB unallocated space) > Next.

Step 5: Complete the Installation

• Install Windows 11:
• Files copy, VM restarts (15-30 minutes). Let VirtualBox handle reboots.
• Setup:
• Configure region, network, account, etc., to reach the Windows 11 desktop.

Alternative: Modify ISO to Bypass Checks (Preemptive Fix)

If you want to avoid registry edits during setup:

• On a Windows PC or Mac with Tools:
• Use Rufus (Windows) or edit the ISO:
  • Download Windows 11 ISO (x64 for Intel).
  • In Rufus: Select ISO, check “Remove requirement for 4GB+ RAM, Secure Boot, and TPM 2.0” > Create new ISO.
• Or manually:
  • Extract ISO with 7-Zip (Windows) or hdiutil (Mac: hdiutil mount Win11.iso).
  • Edit sources\appraiserres.dll—replace with a blank file or delete (disables checks).
  • Rebuild ISO with mkisofs (Mac) or ImgBurn (Windows).
• Use in VirtualBox:
• Attach the modified ISO in VM Settings > Storage > Run setup as normal.

VirtualBox-Specific Tweaks

• Enable EFI:
• VM Settings > System > Check Enable EFI (special OSes only)—mimics Secure Boot-like behavior.
• Increase Resources:
• System > Set RAM to 4GB+ (8GB ideal), CPUs to 2+.
• Display > 128MB VRAM, enable 3D acceleration (Intel only).
• Fix Boot Issues:
• If stuck, add to Extra Data (VM Settings > General > Advanced tab > Custom VM Properties):
  Key: vboxmanage modifyvm "Windows 11 VM" --cpu-profile "Intel Core i7-6700K"

Troubleshooting

• Error Persists:
• Reboot VM, press Shift + F10 again, verify LabConfig entries—ensure all are set to 1.
• Slow Install:
• Use an SSD, increase RAM/CPU in VM settings.
• Apple Silicon (M1/M2):
• Use Windows 11 ARM ISO. VirtualBox ARM support is experimental—LabConfig works, but Parallels or UTM may be smoother.
• No TPM Emulation:
• VirtualBox doesn’t natively emulate TPM. LabConfig bypasses this requirement entirely.

Notes

• Intel Macs: Full x64 Windows 11 support—easiest setup with these steps.
• Apple Silicon: Requires ARM ISO; bypasses work similarly, but performance may vary.
• Legality: Microsoft allows VMs; activation needs a valid license.
• Post-Install: Install VirtualBox Guest Additions (Devices > Insert Guest Additions CD) for better integration.
