[SOLVED] How can I fix Boot Order for Boot Manager M.2 Not Appearing?

[xZGxFire]

So I bought an M.2 SSD which I did install fresh windows 10 and everything, downloaded everything I needed, etc.

I'm booting correctly to the M.2 SSD only because everytime I turn on the pc I get asked which volume of OS to choose and I pick the one of the M.2, but I got 2 other storage devices.
Another SSD (through Sata)
An old HDD (through Sata)

The second ssd has windows os in it, so everytime I turn on the PC I get asked which Volume to pick, I also set the M.2 Volume as Default.

My problem is that I want to wipe clean the second SSD and HDD, but I scared if I do that, my system won't boot and I'll explain why.

MSI Bios
In Bios:
I go to Settings>Boot>Hard Disk Drive BBS Priorities
I get 3 Options because of the 3 drives
Boot Option #1 M.2 SSD
Boot Option #2 SSD
Boot Option #3 HDD

You can see that the order is correct, theres no problem there but...

in Settings>Boot
Under Fixed Boot Order Priorities
Boot Option #1 Windows Boot Manager (HDD)

Theres the problem, I managed to change it to SSD but after exiting the BIOS, I got prompt to insert Bootable Media as if I needed to boot from usb to instanl an OS.

I really would like to fix that, I got pictures but I don't know where to post or link them. I want to format/delete all the contents of the HDD and SSD while having the OS on the M.2.

Background:
I had an OS on the HDD, then I bought the SSD and install the a "fresh" Windows 10 on the SSD. Apparently I never changed the Boot Drive on the bios but I kept booting normally to the SSD. Now I have a M.2 SSD (with also "fresh" Windows 10 ) alongside both normal SSD and HDD.

I was suggested to remove the HDD and see if I could boot like normally. Well, I can't, says to put boot device so I can't boot without the HDD connected. I also tried switchting from Legacy+UEFI to UEFI and nothing works, I can't select the M.2 as Boot Manager (it is recognized in the bios)

What can I do? Remove all drives and just perform yet again a clean windows 10 install on the M.2?

Any time. No rush to wipe drives, make sure to copy everything you want first

make sure hdd isn't added to boot order when you put it back into PC. I seen weird things happen before where people boot to old installs.

I did select 1) Because Disk 1 is the HDD

but the following appeared

DISK
PARTITION
VOLUME
VDISK

I want to wipe all of it. Same goes for the SSD

I just selected them like before and choose which one and typed clean

 

[Colif]

so did it clean them?

i thought those choices were in bios, i haven't run clean myself for a while. Or ever.

Did it, got the HDD and SSD clean, I initialized them in Disk Management. I boot from M.2 correctly.
For the third time, thank you so much for your time and effort!

it should be faster as well

booting from hdd takes forever, my nvme is about 2 seconds after the boot screen.

go enjoy and no more weird boots

Everything is in order, with command console I selected the Disks as before and did Clean, which wiped them completely.
