Solved I disabled intel integrated graphics, asus laptop win 8.1

This is my first post so if there is something i didn't include please advice, also if this is in the wrong section I apologize.
I was very frustrated about a game, not using the dedicated GPU. In my frustration i disabled from the device manager the intel graphics. Suddenly my screen resized, nothing seemed to work so i forced restart. The asus logo appears and is followed by a "windows blue" screen (not BSOD).
I've search online for similar problems,
Things I already tried to avail:
1) I have tried reseting the bios by opening the laptop itself and removing the bios battery.
2) I connected the laptop through VGA and HDMI to another monitor, bot report "no signal"
3) I have tried different combinations of keys to enter bios or safemode, none work
4) [Not a solution but i had no ideas left] I have tried enabling the card "blind" using the keyboard, start+r -> devmgmt.msc etc since i just cant see, it didn't work though i then tried to alt+f4 and shut down and it failed. conclusion maybe the problem isnt the integrated graphics?
5) Booting through a new windows disk, didn't boot. I want to believe that the boot priority is set to hdd for this.

What I concluded so far is that I need windows access to enable access to my bios.
I'm all out of ideas, and very frustrated any help would be greatly appreciated.

My Specs:
Laptop Asus F550C
i5-3337U
NVIDIA GeForce GT 720M 2gb
6gb ram
win 8.1 64bit

Welcome to the forum!

Yea, on these laptops disabling the Intel GPU is not wise as it also controls the discrete GPU.

You mention you can't get into Bios or boot from a DVD. This is before Windows even loads so you should be able to do both. On my machine I can get into bios if I hold the F2 key down while prssing the power button. Don't know exactly which key is your bios key.

Once in bios you need to set the boot order to boot from the DVD, then do a repair install.

PS: Would also suggest getting an external drive and get in the habit of making an image at least every couple weeks. Most imaging software lets you create a boot disc so you can restore the image even if the computer crashes.

PPS: Looked it up and your bios key should be F2.

I have managed to get into bios by removing the hdd and turning on the laptop. Unfortunately the boot options priority is faded (im unable to open it). I have tried playing around with what i could change to no avail.
PS: F2 doesn't work, as of now the only way to enter my bios at the current state is by removing hdd

Try turning off Fast Boot in bios then try to get into bios again with hard drive in.

I have managed to refresh the pc after toying around with the options in bios and rebooting, at some point it actually worked. I did in fact disable fast boot.
Thanks for the help.

That's good news Lilith!
