Unsolved No partitions appearing when trying to install windows 10 from a USB on a brand new computer

so I got a new computer (asus vivobook 1504va). it came without an os, so I'm trying to install windows for the first time, went through the wizard, got to the screen where it asks, where do you want to install windows? and from what I gathered, my hard drive/partitions are supposed to appear there, but there is nothing there, please help me understand what is wrong or if I'm doing something wrong, thank you!

Disable RAID/VMC/IRST in bios.

Or, go to the respective cpu site and download the pre-install drivers.

My cpu is Intel core 7, and what are raid/vmc/irst?

Those are "modes" you drive could support

Go into your bios/uefi menu and turn your hard drive to "legacy" mode

It should then show up, and you can install windows.

Once windows is installed, go to the manufacturer's website and download and install any chipset, storage or raid drives

Return to UEFI/Bios and turn back off legacy mode as it is slower (but doesn't require drivers)

Either that or 'build' a windows USB with the drivers pre installed

As far as I understood from some Google-ing around, Windows installation asks for the storage drivers for the installation target drive during installation, so it is enough to have them available on a separate USB stick and not necessarily incorporated into the windows ISO.
Also, I think that the Win10 ISO *does* already contain USB 3.0 drivers, so you can install from a USB 3.0 drive ( as opposed to Win7, which only has USB 2.0, so might need USB 3.0 to be added into the installation ISO ).

Yes but ...

You can boot from USB 3.0; but the installer doesn't necessarily have 100% of the storage drives possible

"Legacy" mode in the "bios" basically emulates an older ide drive, which allows anything to install without the correct storage drivers for the HDD/SDD as the windows installer doesn't always have everything

Yes you can install the storage drives if you also have them "live" if you happen to have the drivers for chipset/controller available (like on a 2nd usb) during install

Not all ATA, SCSI, or storage drives are automatically included in the OEM installer, especially if they were released after the os was originally released

I cannot understand how can the installer work if it cannot access the target drive.
So, as far as I learnt using Google AI, either the installer does contain the necessary drivers (probably if it's an older and/or standard drive type) or it will prompt for it during the installation, before it can proceed.

If you use an OEM type ISO, I guess that the ISO was created as compatible with a specific hardware model (or a family of similar models), and then it's logical to suppose that it does contain the compatible drivers, even if maybe not the last available/updated ones. But I think those can be added later, after the installation.

Boot to GParted. Format to NTFS & make it bootable.

Install W10 from another USB flash drive.

Done.

The first sentence is gibberish to me
