The other day I started using kali on a Live usb. I decided to go to a graphical install I have a hard drive that is split into two sections data and C. I thought i could have both windows and kali and do a duel boot so I started to install to Data. Nothing went wrong on the install in till I reboot. I went into bios to see if my harddrive was still there and surely it wasn't. I tried to boot from a drive labeled "ST93225AS" just a black screen pops up blinking a - symbol. My other harddrive does not appear. I installed grub thinking i could put windows on later and add it to grub. TIFU Any suggestions?
