Hello again,
I am deeply sorry about this repost, but I was completely unable to interact with my previous post. When Billsey asked for more info, I was completely unable to post a comment to provide the requested info and I don't know why. So here is the same post (again, I'm sorry), but with the requested info.
So,
I just purchased the following laptop:
However,
when I tried to install W10 on it, the installation process did not
find any disk to install it on (I even opened up the PC to check if it
was there and properly plugged in).
Here what I've seen so far:
When I first turn the PC on, I end up in there:
So I restarted the PC, pressing F2 to get in the BIOS, to change the
booting order to boot on my USB key which has the W10 installation
process on it.
But then, when W10 asks me to choose a disk to install it on, the list is empty:'(

And now, the requested info that I couldn't post for the life of me (Advanced tab, Info tab and Main tab):
There is the option to load a driver in the W10 installer (has you can see on the picture above :"Charger un pilote"), maybe that would help? But I don't know what driver I should download and use.
And if that doesn't help, what should I do then?
Thanks in advance for your answers!
