@FXmAniac - @JustinThyme is right.
Your ssd's might not be recognized in the bios boot screens as they don't have any "active" partition or don't have bootloader installed on their "mbr" ( or if you UEFI boot your OSs - then the sdd's /hdd must be GPT formated and include "efi" fat32 partition with *.efi file under /efi/boot/ folder of the 1st partition on that drive ).
Please read my guide ( link in my sig ) to understand the difference between BIOS boot( CSM option enabled )+MBR formatted drives and on the other hand UEFI boot + GPT formated drive ( i.e CSM option DISABLED ).
you
MUST know which type of installation you wish to boot -> then check the requirements ( i.e does your ssd is MBR or GPT formatted ? does CSM option in the bios is Enabled or Disabled ? ) -> then you need to make the RIGHT TYPE OF WINDOWS INSTALLATION USB, and BOOT IT IN THE RIGHT WAY ( again read my guide for more info )
My suggestion is that you'll make whatever changes to your system so that it will boot by the UEFI method ( NOT legacy bios ), i.e format your SSD as GPT, create the boot partition for the *.efi files +MSR partition, then whatever partition you need ( like "c:" for the windows ) - in that order, as my guide describe.
If you still got doubt about the SSDs being not connected, you can try the following:
Make bootable Ubuntu installation usb ( it is free of charge )
Then boot ubuntu - WITHOUT INSTALLING ANYTHING - just by using the "try ubuntu without making any changes to your computer" and also pick "nomodeset" since you got NVIDIA graphics card -
AS THIS IMAGE SHOWS.
then, when ubuntu loads into the desktop open Gparted -> then you can check whatever disk/sdd is connected/not connected and its layout ( gpt/mbr ) and its partitions, and their status ( are they active/non active ? )
Using Gparted you can also convert an MBR formated ssd to GPT - NOTE THAT IT MIGHT ERASE EVERYTHING ON THAT DISK !
Then, after you've made sure the computer can access and read the SSD, so you know you don't have any HW issue - you can:
1. using either Gparted or diskpart ( from windows installation usb, see my guides ) you can format the hole ssd, create first two partitions ( efi and msr ) then the 3rd as WINDOWS ( see my guide for a "how to" ).
2. restore/copy windows from other drive/backup to the ssd's partition for windows ( the largest of them most probably )
3. using windows installation USB fix windows's boot, by running "fix boot" as we explained.
again, most of these steps are covered in detailed in my guide "how to install windows the proper way" - it appears in my sig and it is a sticky thread at the top of the 1st page of this sub-forum - can't miss it.
hope this helps you.
best of luck.
