Switching from Legacy BIOS to UEFI

My XPS 9360 (i7 7th generation with a Samsung 960 Pro 512GB I installed myself) is running well and fast.

My BIOS is set as follow:

Boot Sequence: Legacy (USB & PCIe)

Advanced Boot Options: Legacy Option ROMs Enabled

Secure Boot Disabled.

I have read many posts about it but still ask myself what I should do and why. What I would gain out of it? Is UEFI a better choice?

Test I made but did not commit to it at the end (not saved): If I change the Boot List Option to UEFI I have no Boot Sequence anymore. If I click on Add Boot Option I get the nasty message: “File System Not Found”?!?

I cannot enable Secure Boot since i loose my Boot Sequence.

Humm..stuck here…

Am I missing something?

Thanks again for the precious help.

Hello Speedstep,

Thank you for your reply but what you just wrote is like Chinese to me...we are not all computer smart.

Please explain for the common people what are the options?

Should i leave it as is?

Legacy Booting is NOT ALLOWED on any sata ports for a 7th Gen Processor.  So there would be no MBR or Legacy or INT13 storage available to windows or linux or anything else.  UEFI GPT NON LEGACY is required past skylake.   32 bit drivers are also Removed from support for INTEL and AMD and NVIDIA etc.  From this point on its 64 bit only and Windows 10 only.

32 bit os,  and Legacy and MBR will not boot.

UEFI 2.3.1 secure bootUEFI 2.3.1 secure boot

If you change this you will never boot again.

INTEL, AMD, NVIDIA, etc are going along with microsoft and no longer supporting anything Legacy.

NVIDIA is making the following updates to our operating system support effective April 2018:

Drivers: Game Ready Driver upgrades, including performance enhancements, new features, and bug fixes,
will be available only on 64-bit operating systems.
Critical security updates will be provided for 32-bit operating systems through January 2019.

This includes the following operating systems:
Microsoft Windows 7
Microsoft Windows 8/8.1
Microsoft Windows 10
Linux
FreeBSD

Applicable Products:

  • AMD Radeon™ R5 235X, Radeon™ R5 235, Radeon R5™ 230, Radeon™​ R5 220 Series Graphics
  • AMD Radeon™ HD 8470, Radeon™ HD 8350, Radeon™​ HD 8000 (D/G variants) Series Graphics​
  • AMD Radeon™ HD 7000 – HD 7600 (including A/D/G/M variants) Series Graphics
  • AMD Radeon™ HD 6000 (including A/D/G/M variants) Series Graphics
  • AMD Radeon™ HD 5000 (including M variant) Series Graphics


Applicable Operating Systems:

  • Windows® 10 (32 & 64-bit versions)
  • Windows® 8.1 (32 & 64-bit versions)
  • Windows® 7 (32 & 64-bit versions)

MBR  = Master Boot Record refers to MSDOS Master Boot Record from 1981.

Windows up to XP can actually Dual boot and run from a FAT32 partition with WIN98SE dos and XP Windows.  This is why there are XP installation Diskettes.

There are no Diskettes or ATA support.  ATA is the old IDE interface that goes back to MSDOS as well.

If you install DOS or WIN98 on a machine with SATA drives you have to Set the SATA Operation to ATA/Legacy or the OS will not see any drives.

 

Windows 7 supports ATA/Legacy booting as well.  You cannot install or Run Windows 7 on processors past Skylake.   Its windows 10 only.

Windows 7 goes belly up in April 2020 and Windows 8.0 is already End of LIFE DEAD.  

 

They further force you forward by making Office 2019 only available to run on windows 10.

The last version of Office that ran on the older systems is Office 2010.

Office 2010 works on windows 10 but they want to force you to upgrade everything to Office 2019.

When you install a new NVMe drive on a Dell system, it may present problems.  Do you remember what changes you made to facilitate that install?

But changing to UEFI will need the partitions on the drive removed and replaced with the normal ones, although there is a utility to get around that.  I would still suggest, if it is an option, to reinstall and set the high priced drive up so it works at its full potential.

We can help with that process, we just need to know what you want.

Hello and thank you all for the kind support.

When i bought the machine from a reseller it had no hard drive nor battery. I used a USB key containing Windows 10 (i had downloaded from microsoft) and did a clean installed with a genuine key. I actually did not touch the BIOS...at least i do not recall at that time.

I then installed the right drivers etc. from Dell, plus Samsung driver and Magician. I see in the Device Manager/Storage Controllers it is showing the correct Samsung NVMe driver and not Microsoft.

Maybe i should have thought about looking and setting up BIOS before proceeding?

I love my Touch XPS  ;o)

XPS 9360  8th generation Intel processor  does not allow LEGACY MBR Booting.

Changing is NOT an option.

Core processors past Skylake are ONLY windows 10 and ONLY UEFI GPT.

ALL Newer Dell systems will not boot the OS in legacy mode from an internal drive. This is a half-step toward Intel's goal of removing legacy support altogether -- mostly by 2019, and completely by 2020.

 

This means ONLY windows 10 works and ONLY 64 bit versions.

Hello Saltgrass,

You mention a utility. Care to be a little more precise?

If i listen to you i should actually reinstall the OS and change it to UEFI.

There is no datas on teh drive other than the OS. Of course the pain is to have to reinstall all the drivers etc.

Will it really make a difference? And how can you help me? Are there steps to follow?

Thank you very much.
