Reverse what you did. Disable secure boot and enable legacy support

Tip: You probably has MBR disc partition.

Hello,

You need to enable ptt (platform trust technology) in the bios under security if you want the tpm to work .

regarding the blinking led this might indicate a problem look in this manual expand troubleshooting => system diagnostic lights in what pattern is your led blinking ?

lastly if you want to check if the tpm is working windows key +r and type tpm.msc

You will need to confirm the system model number -- the Inspiron 3511 is a 2022 model.  It does not have a legacy option -- it is UEFI-only.
