Why Can’t You Install Windows 11 on Your Laptop?


You have a laptop.
You want to install Windows 11 on the laptop.
However you got an unexpected error saying that you should visit https://aka.ms/WindowsSysReq for detail.
You visited the page but you are unsure what actually happened.

  1. The first common reason is that you do not have TPM 2.0 hardware.

    Open Settings Update & Security > Windows Security > Device Security
    – If you do not see a Security processor section on this screen your PC may have a TPM that is disabled.
    – If you do see a Security processor section on this screen then click Security processor details, and verify that your TPM Specification sub-version is 2.0.
    If it is less than 2.0, your device does not meet the Windows 11 requirements.

    Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard.

    Trusted Platform Module provides
    – A hardware random number generator,
    – Facilities for the secure generation of cryptographic keys for limited uses.

    Usually you can enable or disable TPM in the BIOS of your laptop.
    If you have TPM 1.2, you can often update it to 2.0 by following the guide of your laptop providers. For example if you have a Dell laptop then you can check the guide here.

    If you get “The TPM is Owned.” issue when updating TPM 1.2 to 2.0 then you can check a guide here. (Press F12 after your laptop is reboot.)

  2. The second common reason is that your laptop processor has not been supported by Windows 11.

    Open Settings > System > (scroll down if needed) >  About.
    Search for processor name, e.g. i7-10610U.
    You should find your processor name here if it is supported. For example the Xeon E3-1505M processor has not been supported.

  3. You can also download PC Health Check app to verify these 2 issues or identify other potential issues.

  4. If you plan to install a fresh Windows 11 from an USB then you can ignore the processor support requirement.

How to Install a Fresh Windows Booted from UEFI Secure Boot using a Bootable USB


Most of Windows machines are delivered with a limited Windows version and unnecessary preinstalled software.

You want to format the hard drive and install a fresh Windows that can be booted from UEFI secure boot to improve machine performance and stability.


You need to have a 8Gb USB stick and an ISO file of Windows 10, version 21H2 or Windows 11, version 23H2.


Step 1: Backup your machine and create an USB recovery by entering “Create a recovery drive” text to the search box on the task bar and follow the instructions.

Step 2: Create a bootable USB with Windows installation files.

If you plan to install Windows 11 then you can use Windows 11 Installation Assistant to create a bootable USB (click Download Now link below Create Windows 11 Installation Media section), and skip the commands below.

If you plan to install Windows 10 then you can use the commands below to create a bootable USB.

  • Right click Windows logo, click Command Prompt (Admin).
  • Enter diskpart.exe, press Enter.
    DISKPART> list disk
    DISKPART> select disk 1 -- the USB disk should be selected, the number may be different in your machine.
    DISKPART> clean
    DISKPART> create partition primary size=1024
    DISKPART> select partition 1
    DISKPART> active
    DISKPART> format quick fs=fat32
    DISKPART> assign
    DISKPART> create partition primary
    DISKPART> select partition 2
    DISKPART> format quick fs=ntfs
    DISKPART> assign
    DISKPART> exit
  • Double click on the Windows ISO file to create a virtual drive.
    xcopy f:\sources\boot.wim d:\sources\ /s /e
    f: the virtual drive and 
    d: the USB fat32 partition.
    We copy only the f:\sources\boot.wim file to d:\sources\.
    robocopy f:\ d:\ /IS /S /XD sources
    f: the virtual drive and 
    d: the USB fat32 partition.
    We copy everything from f:\ to d:\ except the sources folder.
    xcopy f:* e:\ /s /e 
    f: the virtual drive and 
    e: the USB ntfs partition.

Step 3: Install Windows.

  1. Plug the USB to a machine.
  2. For a Dell laptop, power on the machine, press F12 until a one-time boot up menu appears. Select the option to boot the machine from the USB. (You may need to access BIOS to select the UEFI option for Boot Sequence, and select the AHCI option for SATA operation).
  3. For a Sony VAIO laptop, power off the machine, then press the Assist button to enter VAIOCare. Select the option to boot the machine from the USB. (You may need to access BIOS to enable the option to boot the machine from an USB).
  4. For a ThinkPad laptop, power on the machine, press F12 until a one-time boot up menu appears. Select the option to boot the machine from the USB. Alternatively go to Settings > Update & Security > Recovery, click the Restart now button under the Advanced setup section and follow the instructions to boot the machine from a USB.
  5. Follow the instructions to install Windows. Set Windows partition size to 614516Mb for DellPrecision if you want to have 600Gb C drive, or 262260Mb for DellXPS if you want to have a 255Gb C drive, or 819815Mb for ThinkPad if you want to have a 800Gb C drive.
  6. You can delete all the partitions, including MRP (Microsoft Reserved Partition – this is just a reserved partition for Windows later use if needed), ESP (EFI System Partition – this is where UEFI firmware files are stored to boot Windows), WINRETOOLS (Windows Recovery Environment (WinRE) Tools – this is where files for repairing or recovering Windows are stored), and PBR image (this is where original the manufacture Windows installation file  are stored) because you already created an USB recovery in the Step 1.
