PC Boots From Live USB, but Won't Boot From Hard Drive. (Error PXE-E61 Media Failure)

Hello,
I recently installed Kali Linux, and had a few problems with my computer booting from the live usb, but those were resolved a few days ago from my time of writing this. I am attempting a dual boot of Kali with Windows 10. My old PC is a Gateway with an i3 and 4gb of ram. However, after booting from live usb and completing a graphical install of Kali Linux(2016.1), my computer displayed this message:

PXE-E61: Media test failure, check cable
PXE-M0F: Exiting Broadcom PXE ROM
No bootable device -- insert boot disk and press any key

I can reboot my laptop with the USB drive installed, and it will boot into the standard live Kali start screen, but otherwise I get the above message. I have tried pressing F2 or F11 to change the boot order, but nothing seems to work. I am getting worried that I may have erased an important part of my windows partition.

A few questions: what drive partition/location would you guys recommend for the grub loader? I am worried that that might be what I overwrote windows with, and am concerned that the system can't locate it on startup. It's currently in /dev/sda Will I need to re-install Windows? Also, during the install Kali said that it didn't detect another OS on the device, which may be what my problem is.

I tried to include everything I though might be relevant, but if I missed something important please leave a comment asking for more information. I'd really appreciate any help I can get with this.
Thanks.
