It did show up in the bios screen previously when I formatted it with rufus, but it didn't go to the installation screen, it went to a GRUB command line, and when I tried some commands I found on here for similar GRUB screens issues, like root (hd1), it said 'root is not recognized as a command'. SO I redid it with unetbootin, I restarted the laptop, opened bios and nothing. Only option is my SSD with windows on it.
Back in windows, when I plug it in, it doesn't show up in file explorer, though it does show up in Devices and printers screen as a USB mass storage device.
I'm running windows 10 pro from an installation media, my laptop model number is K46CA. Not sure what other info you need to help me but glad to give more.
ALSO I can't reformat it because no program I have can detect it.
