[Guide] NVMe-boot for systems with legacy BIOS and UEFI board (DUET-REFIND)

is this mode the one that should work for my board then?

Do you see a device named "PATA" or "PATA_SS" within the "BOOT" section of the BIOS? If yes, the modification and the flashing of the modded BIOS was ok.

well, I've read those lines a few times now and tryed a bunch of Usb drives and 4 different Isos, with the cluster size at 32 kilobytes (like you showed) and 4096 bytes (default by me and always worked that way...)

On Vaio Bios I have:
Boot mode - Legacy/UEFI (if I choose Legacy and try to boot from the Usb Drive it reverts to Vaio Care for me to change Bios Settings or boot again from Usb, if UEFI is chosen it just goes to a black screen with "Operating System not found")
Secure Boot Enable/Disable and when enabled I get a Sub-menu Keys (should I do something here in Keys?) I have it set to DISABLE
no Fast Boot menu
No CSM menu
and no OS type option also...
No PATA or PATA_SS anywhere, only Internal HDD Drive on Bios
I even took out and disabled WIFI Card and disabled Card Reader as well...
I know all this options from my ROG boards but this one from Vaio is very limited.

I'm running out of options and unless I can unlock some of those Bios Menus and Sub-menus I can't change much more... that of course if those menus are present on my bios...
I might need some help unlocking them if I have to...
If none of you guys can help/ guide me, I will have to try the clone install version but in my opinion, that just nearly ruins the whole point of modding the bios if one can't boot install directly to Nvme.
Cheers

@Fernando:
Sorry I made a mistake when writing... my bad...
actually UEFI boot send me back to Vaio Care screen to change Bios settings or boot again from Disk/Usb, and Legacy option gives "Operating System not found"
But here you have the screenshot.

P.S. I can make pics from all my bios screens if it helps you have an idea of what I have here...

So I bit the bullet and updated my bios with the modded one. It appears to have worked as expected. I now have a PATA entry in the boot section of the bios. Booting from that appears to do something.

Until I can figure out a simple way to clone my current win 10 pro system drive. I can't tell if I was completely successful.
Using minitool partition wizard to copy and convert old mbr drive to GPT looks like it worked but I haven't yet successfully booted the OS on the GPT drive.
Perhaps I can do a system repair from a recovery disk?

So...its simple, it didnt worked at all...
Why do people always look to the easier and dont look for a healty/performance system.
Do a clean OS install on or new NVMe and get rid of all the junk and configuration from older OS, follow the guide...its so much breathable.
Takes same time operation or less if u r an experienced user...
I do like and try to serve a costumer the best i can in their machine, but my systems are the holy grail, the best performance and time dedication to get the most of it...
And i suspect that the Asrock Z68 is yours...not a costumer...desktop machine? Holy crap...do a clean install m8

@Nuor - I agree with MeatWar - Clean install per #4 of the "This is what you should do" section at page one is suggested, but if you must clone >>
Installing Clean Win7x64 on M2.2280 PCIe Gen3x4 SSD A-DATA SX8200 Pro << My way

I don't disagree with either of you and appreciate the wisdom of your advice. I have a reason; not necessarily good, but a reason. This nvme drive is not supposed to stay long term in this system. It was bought to be the boot drive in a new 5900x that at this rate may never get built ;/. I wanted to test it out along with GPT and UEFI as I have never used a system that had either on the system drive. I didn't want to buy a new windows OS until the rest of the system came together. So I just thought I'd clone my existing OS over and play around with it in the nvme uefi boot system. Good news is I managed to get the OS cloned and bootable from both the original ssd and the new nvme drive (from windows boot manager entry in bios boot menu). I lost access to my linux drive unless I boot from original ssd but I imagine there is a simple solution for that problem.

@helderzh:
Please re-read and follow carefully my advices given within the point 4.

By default modern UEFI bios machines r all x64 EFI enviroment...and no option to engage the system motherboard in EFI x86...so u can have an no go on win10 x86 installation PURE UEFI or many issues on the task.
On the other hand...in CSM u can install it.
The bios limitation on 500GB???? An SSD is treated like a Hard Disk/Storage device to the eyes of a bios
Thats a very very old behavior...not present in recent hw...there was a limit of 2Tb disks and limitation by OS file system...FAT32 in the past.

@MeatWar
This is not a new laptop, is dated 2013 and there are very limited options in bios.
As for the 500gb limit, 512 ist the one installed and i haven't tryed larger but it seems to be overall written that this laptop only takes that size. And it only has an m.2 connector with a pre installed 256gb toshiba ssd
