(picture is blurred a bit because had just a second to catch the error before laptop shuts down)

the FAILED part is causing the problem [failed umounting CD-ROM]

Spec:
128gb m2 ssd windows
500gb SATA ssd(made 25gb unallocated for installation)

made a GPT UEFI bootable onto a 16gb usb using rufus

Was there a disc in the drive? If this is a USB installer that was shutting down? I suggest re booting the live Installer and than shut down again see if it continues. Maybe re create the USB installer.
