I'm trying to help a friend install


After "Fast Boot" has been enabled, you cannot access the BIOS setup during power on . The machine will bypass "Press F2 to access Setup Utiltiy and F12 for Boot Menu" prompt.
This is a bigger issue if the hard drive crashes and access to Windows is not possible OR

Fast Boot can be enabled or disabled in the BIOS setup, or in HW Setup under Windows.
If you have Fast Boot enabled and you want to get into the BIOS setup. Hold down the F2 key, then power on. That will get you into the BIOS setup Utility.
You can disable the Fast Boot Option here. You will need to disable Fast Boot if you want to use the F12 / Boot menu.

Install to pc


Power on the computer and enter the BIOS menu. It will tell you which button to press to enter setup. Generally it will be F1, F2 F10 F12 or Del.
At this point you can insert your operating system disc.
In BIOS navigate the menus and look for Boot Order, or similar Make sure CD/DVD boots before anything else
Press whichever key the menu states to save and exit (Probably F10)
When the computer boots it should either start booting to the installation setup or ask you to press any key to enter installation. Do so and follow the prompts to install your operating system.
Post if you need more info.

No operating system found


If the error message says "No operating system found" it is most likely a faulty disk controller or a faulty hard disk.
Reseat the hard disk, if this doesn't work you need to test the hard disk another way. Remove the hard disk and connect it to an USB hard disk adapter and connect it to a working computer's USB port. If this computer sees this as an external hard drive and you can open the folders and files then the hard disk is OK and the fault is the disk controller on the the 4115c laptop.
If the hard disk is not detected then the hard disk is faulty. You need to install a new hard disk, install Windows and the laptop's device drivers and programs to get a working laptop again.

Laptop A3 not booting up


Sounds like your hard drive is not booting and that your keyboard isn't responding to your pressing F2 and F12. If you can locate a USB external keyboard or if you have a round PS2 port for an external keyboard/mouse - plug into the laptop with that then press F12 while the computer is booting, press it a few times to be sure you get it in the buffer - then the boot manager should show up. If it does, choose to boot the Hard Drive if available - same with pressing F2 - Setup or Bios CMOS Settings should be displayed, here you can try to boot from the Hard Drive or Check to see if the hard drive is being recognized or not.

You may need a new keyboard if your laptop keyboard doesn't get you into either menu, and to either make sure your hard drive is responding and can be set to be the default boot device.
