NO FULL PC model NOT told
the oldest I thing is 2014 (w8?) OCT , 2012 is w8 first. (model 15 - 3000 - secret sub model)
the service tag on this PC has the full model number, and was not told by you
the tag is on bottom of this PC or in the battery wells side walls. look>?>
WHAT DO YOU MEAN BY LEGACY. (sure the bios page switch sure)
1: YES, IT HAD THIS IN VERSION 1. It sure did, did you look first , ???
2: TURN IT OFF OR ON; NOT TOLD but is moot point. so far, no needs told.
3: DID YOU LOOK FIRST OR ASK HERE FIRST , FOR ALL 20 VERSIONS OF BIOS USED ON THAT PC.
4; NO REASON TOLD WHY, TO BOOT DOS OF WINDOWS 95 IN MBR BOOT. MODE? NOT REASON TOLD.
Did you forget to look first, ? or ask 1st to persons that have never seen all versions (20) on this series of PC
there are many in the series and sold in USA and outside and are NOT THE SAME
NO PC TOLD>
15 3000? (this is not a PC it is ONLY A SERIES)
or ask at dell.com forum. but wait they will not talk to you lacking real model numbers in full or full service tag information told.. sorry that is how facts are learned
WHAT PC you have.
yes some older models had a LEGACY setting in BIOS for sure.
and most PC upgraded this is removed due to UEFI class 2 rules. or class 3.
all mine are class2, and no legacy seen on any dell bios page
and I use GPT boots and in non secure boot mode.
20 version of BIOS there, or more by country not told.
if you meant use non secure boot.
then the answer is here, (even told at Microsoft.com)
to turn on secure boot is easy, just turn it on bios page.
to go the other way is never easy. but here is how.
backup all data. first
set bios to secure boot.
then reload windows, fresh.
not easy see?
Legacy is a factory only for MBR boot drives, that are now banned or at last update BIOS now banned.
or buy a PC that supports CSM mode, like my DIY ASUS, Z270PRIME ,
CSM IS THE LEGACY MODULE THERE
DELLS HAVE NO CSM NOR WILL IT ALLOW TODAY TO REGRESS BIOS VERSIONS.
TRUE AT MOST OEM MAKERS OF PC.
ask at dell.com
let me type that for you.
