I would like to start by saying thank you, and sorry I'm a moron

I am an aspiring pentester, and decided to load my computer up with some Kali Linux to get started with some pentesting classes on Cybrary. I started by partitioning my hard drive in windows for my Kali system, and ran an install from a USB drive. Everything worked fine, except the Grub bootloader wouldn't boot me back into my Windows system. After searching the web, downloading the Windows ISO, downloading a "boot-repair" ISO, and other failed solutions, I decided to try another install using the other bootloader option in the Kali set up. Well for whatever reason, it wouldn't allow me to set up my system with that loader, so I went for the final option of installing without a bootloader. My thinking was that without a bootloader, that possibly the stock loader would kick in, and I could get into Windows to start over.
After the installation was complete, my system rebooted and showed the stock "Lenovo" splash screen, and then to a black screen with a blinking line...and nothing happened. I have tried restarting, restarting with a USB drive while pressing every combination of "F_" button, and I can't get to anything. I then read something about taking my computer apart and unpluging the BIOS battery in order to reset my BIOS, so I did that to find no such battery. So right now I'm stuck with a blinking paper weight, and in dire need of some direction.
I have a Lenovo Ideapad P500 that came with and was running Windows 8.
Thanks again for any help, I feel like such a noob being an aspiring IT guy and all, but I'm fresh out of things to try.
