Enable TPM
I have an Inspiron 5570. I enabled the TPM (followed all the steps) but when I rebooted the laptop I kept getting " boot device not found". I went into the BIOS and there is a hard drive showing.
I had LEGACY enabled before trying to enable the TPM.
I want to upgrade to Windows 11

UEFI is required for TPM. Systems with Windows in Legacy mode need to have Windows reinstalled. Also, note that Windows 11 is a waste of your life. You'll be disappointed. Trust me.

TPM requires UEFI, which in turn means you must either convert the drive to GPT or reload Windows once you've disabled legacy mode and have the system running in UEFI mode.
You can't simply turn off legacy mode without converting the filesystem or reinstalling Windows. In UEFI mode, you must have a GPT filesystem on the drive to boot.
