Question: Macbook pro stuck at boot screen with apple logo and 100 percent progress bar.
Some keys i.e 4RFV not working on my macbook pro keybaord and sometimes the keys get pressed automatically. While the laptop was working fine with onscreen keyboard, yesterday after turning it off, it is now stuck at boot screen with apple logo and 100 percent progress bar. Even while restarting, it shows only 100 percent progress bar within 2-3 seconds of turning on and is stuck there.
I cannot start recovery as R is not working.. I have made a bootable el capitan usb to reinstall the operating system but even after pressing option, it is not going to the disk utility screen.
I tried taking the hard disk cable out connected to logic board and then starting the laptop with bootable usb plugged in and option key pressed, it still shows apple logo with 100 percent progress bar.. confusing...
If i donot press any key and turn it on with bootable usb plugged in, again it shows apple logo and gives some error message for a second and restarts again.. below is the screen shot.. Please help!!
