[NAME]  - So having Legacy enabled explains why you can't enable TPM. Once you disable Legacy, you may need to enable Secure Boot to enable TPM, even though Secure Boot isn't required for Win 11. You should still be able to boot from USB to install Win 11 with Legacy disabled, as long as you plug that USB into PC with power fully off. Then power on and tap F12 to open the boot menu and choose the USB boot option. But why do you want to do a clean install of Win 11? Why not just do an update to Win 11 which will keep all your personal files and apps so you won't have to reinstall everything? (NOTE: Always a good idea to back up your personal files before doing an update like this!)   You can use the "Windows 11 Installation Assistant" here, rather than the "Create..." option on that same page.  EDIT: You will still have to enable TPM before running the Installation Assistant.
Hi, I want to upgrade my desktop (Inspirion 5477) to Windows 11, but found that I can't upgrade without enabling TPM.So I looked at the settings in the BIOS, the setting turned grey and cannot change. [IMAGE] I followed this article.[URL] Turned off Secure Boot still no luck Under Security Settings: Disable PTT, Enable TPM, Activate TPM, then save the changes [IMAGE]I know that my computer should be upgradable.
