#2 Guide: How to Fix "This PC Can't Run Windows 11. Your PC must support Secure Boot" Error

Windows 11 Requires Secure Boot

The detailed error message is: "This PC can't run Windows 11. Your PC must support Secure Boot. Although this PC doesn't meet the system requirements to run Windows 11, you'll continue to receive Windows 10 updates."

Most modern Windows 10/8 computers come with Secure Boot enabled. It's a security feature that keeps your computer safe, and you'll need to turn on Secure Boot if you're updating or installing Windows 11.

How to Fix Guide:

1. Check if your system supports Secure Boot

Step 1: Press Windows key + R, type msinfo32.exe, and press Enter.

Open System Information from the Run dialog box Open System Information from run dialog box

Step 2: In the System Information window, select Software > System Summary.

Step 3: Scroll down to look for a section named Secure Boot State, as shown below.

If Secure Boot State says “Disabled,” your computer supports Secure Boot, and you can skip to Part 3 to enable it.

If the Secure Boot state says “Unsupported,” it means your computer's hardware doesn't support Secure Boot. To fix this, proceed to the next section to check if your computer supports the UEFI mode.

2. Check if your computer supports UEFI mode

Step 1:  Restart your computer and press F2/F10/Delete to enter BIOS.

Step 2. Look for the Boot Mode section in the boot menu to see if your computer supports UEFI.

Check for UEFI mode

If you see an entry for "UEFI Mode," that means your computer supports booting in this way. If it's currently disabled, proceed to the next guide to enable UEFI and Safe Mode.

Note that if your PC doesn't support UEFI mode, you won't be able to enable Secure Boot and upgrade to Windows 11.

3. Enable UEFI mode and Secure Boot

Enable UEFI mode:

Step 1: Open Disk Management and check if the system disk is of GPT type.

If not, convert the OS disk to a GPT disk first, because UEFI and Secure Boot require the GPT disk type.

Here, we recommend using the Partition Master Professional tool with disk conversion capability. It can convert a disk to MBR or GPT without deleting any data or partitions.

Step 2. After the conversion, restart your computer and enter the BIOS. Go to the Boot menu, click on Boot Mode, and select “UEFI.”

Step 3: Save the changes and restart your computer.

Enable UEFI boot menu

Enable Secure Boot:

Step 1. Restart your computer and enter the BIOS settings again.

Step 2. Access the boot menu and enable Secure Boot.

Enable Secure Boot

After this process is done, you should now be able to proceed with installing the Windows 11 update on your computer.

Guideline 2: How to Resolve the Error "This PC Can't Run Windows 11. System disk needs to be 64 GB or larger."

Detailed error message: "This PC can't run Windows 11. Your system disk needs to be 64 GB or larger. Though this PC doesn't meet the system requirements for running Windows 11, it will still receive Windows 10 updates."

System disk needs to be 64GB or larger

This error message indicates that your system disk space is running low, which often happens on older computers. Here are two suggestions for you:

1. If your computer is older than 2015, we recommend staying with Windows 10.

Title: How to Upgrade the OS Disk to a Larger One: A Step-by-Step Guide Introduction: In this comprehensive guide, we will walk you through the process of upgrading your operating system (OS) disk to a larger one, ensuring that you have ample storage space for all your applications, files, and system requirements. The instructions provided here assume a UTF-8 encoded environment. Step 1: Back up your data Before beginning any major system change, it's crucial to back up all important files and data. Use an external hard drive or cloud storage service to safeguard your documents, photos, and other essential items. Step 2: Check your current disk information Open the Disk Management utility on your computer to view the current disk details. On Windows, press Win+R, type "diskmgmt.msc," and hit Enter. On macOS, open "Disk Utility" from the Utilities folder within Applications. Identify the OS disk and note its size and partition layout. Step 3: Choose a new larger disk Purchase a new, larger internal or external hard drive with the desired capacity. Ensure it's compatible with your system and has a faster interface (e.g., SATA III, NVMe, or USB 3.0). Step 4: Create a system image Windows users can use the built-in "Create a system image" tool found in Settings > Update & Security > Backup. macOS users should create a bootable clone of their system disk using tools like Carbon Copy Cloner or SuperDuper!. Step 5: Connect the new disk Connect the new, larger disk to your computer. If using an external drive, make sure it's properly connected via USB, Thunderbolt, or another supported interface. Step 6: Clone the OS disk Use a cloning software such as Clonezilla, Acronis True Image, or macOS's Disk Utility to clone your existing OS disk to the new, larger one. Follow the software's instructions carefully, selecting the source (current OS disk) and destination (new disk) appropriately. Step 7: Verify the clone Boot from the new disk to ensure that the clone was successful and everything is functioning correctly. If there are any issues, refer to the cloning software's support resources. Step 8: Remove the old disk and expand the partition Once you've verified the new disk works, safely remove the original OS disk. In Disk Management (Windows) or Disk Utility (macOS), expand the partition on the new disk to utilize the full available space. Step 9: Update system settings and boot order If using an internal drive, update your BIOS/UEFI settings to set the new disk as the primary boot device. This step may not be necessary for external drives, as they typically boot automatically when connected. Step 10: Restore your data Connect your backup drive and restore any additional user files that weren't included in the system image or clone. Conclusion: By following these steps, you should now have successfully upgraded your OS disk to a larger one without losing any data or causing disruptions to your system. Remember to keep your backups up to date and always proceed cautiously when making changes to your computer's hardware or software.

1. Purchase and prepare a new hard drive - preferably an SSD

    • The new disk must have a capacity greater than 64 GB. • It is recommended to use an SSD when replacing the system disk. • In Disk Management, initialize the disk: right-click on the SSD > Initialize > Select "GPT".
