Manjaro Linux does not detect my SSDs

I have 2 SSDs in my computer, the installer says there’s no partition. I looked in GParted and there was only one partition on my USB Flash Drive I’m booting from. I don’t know what to do. Also, if you were wondering what’s on my 2 SSDs, one is a NVMe with my original Windows installation, and a Sata with a PopOS installation. What do I do?

Are you booting in EFI or legacy-bios ?

I haven’t used the computer I’m booting from in so long I forgot. I may have to check the BIOS on here. Also, which one should I be booting in?

I do know I disabled secure boot, I might be booting in legacy-bios, but when I used windows the configuration said it was a UEFI system so I could also be booting in EFI.

if it has secure boot in it, it is EFI. get a terminal in the installer and, run;

$ ls /sys/firmware/efi

if it returns a directory with contents it is in EFI mode

for UEFI

UEFI, create a profile and save for Windows and another for linux

recheck all option in your UEFI ( for linux)

SecureBoot off
Fast Boot off
No Legacy
all disks on AHCI

boot only on UEFI:< USB vendor name > <partition 1> → EFI install manjaro

you can check in terminal , before install

inxi  -Fxza
test -d /sys/firmware/efi && echo efi || echo bios
sudo efibootmgr -v
sudo parted -l
