Windows 10: I can't switch from UEFI BIOS boot to Legacy.

UEFI is selected in my bios but when I boot my computer it says I am still in UEFI, even after I rebooted my computer.

How do I switch from Legacy BIOS to UEFI?

I wish I'd read something like your linked article before I began. Instead of switching of fast boot and secure boot I changed the BIOS to legacy. But maybe I wasn't clear in my question. My problem now lies in step 2. HOW do I change my BIOS settings to UEFI?? I can't find any BIOS UI of any sorts anywhere.

Return to Legacy from UEFI - BIOS

Hi There

A while ago I was helped here to change from Legacy to UEFI. However, since then it seems, the Laptop (Latutide E6420) is running a bit slowly which was otherwise very quick until then. Now, it takes nearly a minute or so to boot up or shut down or even
to close a file. Just a couple of days ago, I updated the latest BIOS for this machine recommended by Dell.

I tried to go back to Legacy but the system was asking me to reset to UEFI or face boot problems. One advise said that I could disable 'Secure Boot' in Boot Manager and reset to Legacy. However, the Boot Manager is listed under UEFI Boot process and it only
starts Windows. Is there any way as easy as I changed it? This is absolutely under the hope that all will be as normal as it was in the beginning. Please give your thoughts and advice. Thanks.
