If you want to install operating system through bootable
operating system
CD/DVD and you are not able to make any changes in
BIOS like changing
the first boot sequence to
CD/DVD drive, then you have to first clear or reset
the
BIOS settings to factory default and make any changes you desire.
Procedure:
Switch of the computer. Open the CPU cabinet and look for
the battery placed on the motherboard.
Remove the battery
and switch on the computer. Now you should be able to see "
CMOS ERROR " press
F2 or
F10 or
DEL
to enter
BIOS. The error message varies depending on the manufacturers of the
motherboard and
BIOS. Switch off the computer now and put the battery back to
motherboard and switch on the computer and press
F2 or
F10 or
DEL to enter
BIOS depending on your
BIOS
manufacturers. You should now be able to make any changes to
BIOS. Remember, any
changes made to the
BIOS will not be saved if there is no battery placed on the
motherboard.
