I have two hard-drives and installed separately Windows 7 and Ubuntu 12.04 on them. UEFI and "Fast Boot" are enabled in BIOS. I was unable to make dual boot through GRUB menu but was able to do that changing boot sequence from BIOS setup. I have tried to fix the dual boot issue using rEFINd boot manager. As rEFINd did not allow me to dual boot I have decided to remove rEFINd.
# rm -r /boot/efi/EFI/refindor
$ sudo rm -r /EFI/refindaccording to rodsbooks.com instructions.
Then I have changed boot sequence in BIOS menu and removed rEFINd from boot options. After a reboot my machine starts as usual with a specific click and after that it is just a black screen. All indicator lights are on and I can hear fan and hard-drive working. I can no longer boot into Asus G75VX BIOS menu.
- I can even use DVD disc drive.
- However inserting a Live CD for both operating systems does nothing.
- Pressing F2-F12 or Esc keys are not working as well.
Is there any software way to fix the problem or I have to replace BIOS chip?
