Laptop Model : Asus N46VZ

so my laptop is windows 10, and wanted to install windows 8.1 through Flash Drive.
and then when i wanted to change the boot order in BIOS, i couldnt find my flash drive, so i googled it and found that i have to change some "BOOT" setting in bios (tbh im not sure if i messed up the step).

so basically, what i change in BIOS is "Launch CSM", from enable to disabled, just that, and then i press F10 to Save changes and exit, and it will restart, but when my laptop got restarted, my display just got black screen while fan and indicator led is ON. it doesnt POST at all.

so the state on my BIOS setting is , Launch CSM - disabled, Fastboot - disabled, and Secure Boot - Disabled.
the rest is normal.

what i have done :
- shutting down the laptop, removing the AC Adapter, removing the battery , and holding down the power button for 1 minute. and i got nothing, still the same.
- remove the CMOS battery for 20 minutes, put it back and still got nothing.
- switch RAM position, still nothing. i only have 1 ram, but my laptop got 2 ram slot.
- pull out my SSD (windows 10 installed) , still nothing , well of course it wont even POST.

i run out of ideas, my guess is that the BIOS didnt reset even tough i removed the CMOS battery, actually i wanted to find the jumper, but i seems cant find it, does laptop's motherboard got jumper like PC's motherboard ?

Please help me, thanks !
 
Hi, this is true, you still have pads (jumpers) on the laptop motherboard, if you find them, always short the first two pads (with the number 1 in the description) never the other pads with the number 2. The second pads have a process to follow.
