boot with secure boot

Hi.

I need SECURE BOOT to be enable to install Windows 11 but when it is enabled it says no boot image found.

Any suggestion how to boot with SECURE BOOT enabled?

Thanks a lot.

Hi:

Your PC is not supported for W11, for a couple of reasons...one being the processor and the other not having a TPM 2.0 security device.

W10 is probably installed in legacy mode which uses a different partition scheme (MBR), and secure boot requires the GPT partition scheme in order to function properly.

Enabling secure boot would require you to reinstall W10 by booting from your notebook's EFI boot devices...EFI USB or EFI DVD.

If you install W10 in EFI mode, you then should be able to turn the secure boot setting on.

You can bypass the W10 hardware checks and install W11 in legacy mode with no need to be concerned with secure boot, or reinstall Windows.

This link provides the easiest way to upgrade to W11 on your notebook as it sits.

Before upgrading or clean installing W11, I would make a system image of your current W10 installation prior to updating to W11, so you can easily reinstall W10 in the future. 

I used the free Macrium Reflect software to do that, under the Backup at Home section. 

Along with the system image, make sure you create the bootable DVD or USB rescue drive you boot from to access the system image stored on your portable hard drive.

What steps to reinstall W10 with secure boot.

You're very welcome.

Download the latest W10 ISO file from the link below.

Download Windows 10 (microsoft.com)

Use Rufus to create a bootable USB installer.

Set the partition scheme to GPT in the menu and then boot the installer from your UEFI (EFI) USB flash drive option and W10 should install in EFI mode.

You need to be able to boot from an EFI Boot source.  That is the important part.

If you have a separate option to disable legacy mode, but leave secure boot disabled too select that option, and after W10 installs, you should be able to set the secure boot setting.
