Asus X99 Deluxe/U3.1 - Unable to upgrade due to disknumbering (BIOS-issue)

[asw62]

Am facing a major problem - I can not upgrade Windows... due to disk-numbering

Asus X99-DELUXE/3.1 BIOS 3505 UEFI (Jan.13, 2017) LGA2011-3

SATA ports:
nbr 01: Samsung 850 Pro SSD (with Windows)
nbr 02: Samsung 850 Pro SSD
nbr 03: WD HDD
..etc..all ports ports used by HDD's
nbr 07: Asus DVD (BC-12D2HT)

then
nbr 08: nothing connected
nbr 09: Samsung HDD (HD204UI), SATA, I had a free disk left somewhere an connected it later
nbr 10: nothing connected

Now, the issue:
Windows 10 diskmanagement puts SATA port nbr 9 (Samsung) as 'DISK 0' and SATA port nbr 1 as 'DISK 1'

Because of this, upgrading Windows 10 is NOT possible!
Even not after formatting the Samsung drive...

So, with this configuration, installing Windows 10 (from USB installer) on a formatted drive is -not- possible.

After many, I many, attempts (it took about 10 days) I finally figured out that Windows -requires- to be installed on 'DISK 0',
that is to say, DISK 0 in Windows diskmanagement. I wasn't aware of that.


In BIOS I therefore disabled SATA port 9.
In Windows diskmanagment the Samsung drive became DISK 0, as per 'Windows requirement'.
But even then installing the upgrade still failed . . .

Only -after- formatting the Samsung drive, I could install Windows 10.

I am sure that this has something to do with DISK 01 and DISK 1 assignment.
After upgrading and re-enabling SATA port 9, within Windows diskmanagement Windows shifted to DISK 1 again.
Probably all internal references within Windows are related to DISK 1.

Therefore the next upgrade again was not possible.
Even after disabling port 9 and after disk 1 shifted to disk 0, probably Windows still assumes it is on DISK 1,
This lead to upgrade failures.

Only a clean install solves this (Windows does not anymore assume it is on DISK1)

Each upgrade should therefore be a clean install!

THE big question: HOW to have SATA port 9 assigned to any other DISK-nbr than DISK 0.
e.g. DISK 5, 6 or whatever, but not DISK 0.

It seems that Windows disk-numbering may differ from the BIOS numbering, i.e. there is no relationship.

FWIW: Windows Device Manager -> Storage controllers, it says: ""Microsoft Storage Spaces Controller"

Thanks!

Doesn't sound like you've tried it with all other drives Unplugged. Should always install Windows with no other drives available or plugged in. If there's only 1 drive it will be Disk 0. It doesn't matter if it's Disk 0 after Windows is installed, you choose the boot option in the BIOS.
