[SOLVED] Predator helios 500, invisible SSD during windows setup

[dekzzz]

Hello everyone!
First of all, I'm not sure if I'm in the right cathegory but here goes...
So basically I booted win10 from my usb and reached the step
where you're supposed to choose a partition where you wanna
install your Windows, except I only see my HDD. SSD is nowhere
to be seen. There already IS a preinstalled win on my laptop but
I really wanna install a clean copy.
Also bios is super locked and limited with options and looks totally
outdated aswell.

Anyone had a similiar issue or at least has an idea how can I install
a new copy of windows on my SSD ?
Thank you

UPDATE: found the solution myself. Simple as changing SATA mode in bios to AHCI.
After that all the partitions showed themselves.
