Hello there!

I've got an Asus Hero Strix 2 GL504GM that used to run Windows 10, when the thing still worked.

It will not start up, it will show the ROG logo and the loading icon for hours and hours on end. I've tried opening the BIOS from the startup/loading screen and to reset to factory settings. If I do so it tells me there is no space on the disk to do so and to free up space, which I feel I'm unable to do without the thing starting up.

I've tried every option for reset it gives me, locally, from the cloud, with removing personal files, without removing personal files, complete wipe for re-use, but none of it seems to work. If I try the cloud option it says to do it locally, and for all local options it will say there isn't any space on the disk.

I feel the only option I have left is to bring it to a repair shop for them to figure it out, but I'd rather try to fix it myself obviously, is there anything else I can try?
I'm not all to concerned about losing files, I'd rather keep them, but the laptop hasn't been used in like 6 months as the battery is also shot so I started using my work-laptop. If I can get it to work again I want to replace the battery.
