This is propable the only place I can get help now.
After stumbling all across the web, I've found nothing on this case.
I recently bought a netbook, Jumper Ezbook 3 Pro, which has m.2 slot. So I plugged in my new 120GB WD Green SSD, extracted product key using PowerShell and proced to clear install Win10. I wiped all drives and partitions clean, both the SSD and soldered on 64GB eMMC storage which defaultly contained Windows, when it came to me. Right now, I've been trying to install Win10 for like 8 hours. It sometimes won't install at all, giving 0x80070057 error, sometimes it will instal normally, but then BIOS won't find it as a bootable drive, despite me seeing around 10 gigs taken up on that drive. When trying to install on this drive again it warns that it will create windows.old. My BIOS is very limited, it came that way from the manufacturer and I can't flash unlocked BIOS, because I can't boot into windows. I also tried creating partition to install windows on using diskpart, but I can't seem to manually create GPT partition.
