Workshop 02 - Operating System Install
- Ensure your case is closed/fits tightly
- Connect your keyboard and mouse
- Set-up your monitor, connect the VGA cable
- Connect power cables into the monitor and case last
- Try the power button!
If correctly assembled you'll see:
- Green power and hard drive LEDs flash
- Then power LED stays on and
- Fans start up (quietly)
- BIOS screen flashes
Congratulations! Please assist others.
- Is it fully plugged in?
- Does the power switch click? (Try removing the front panel and press it directly.)
- Check power switch connection to the motherboard. (Unplug the power lead, open case and check the front panel power header is connected.)
- Check power cables from the PSU to the motherboard. (plugs only fit in one direction, so don't force them.)
The Power On Self Test (POST) checks your computer when it turns on. It is quick and only stops on errors.
If your computer turns on but doesn't pass POST, it tells you with lights and beeps.
Most errors are easily fixed.
- Is the fan cable plugged in and air guide installed correctly? Are heatsink screws tight?
- Is your processor is sitting in the socket firmly? Are heatsink screws firmly tightened?
- Is the CPU power connector connected?
- Is your RAM firmly clicked into place? Test RAM individually.
- Please ask for assistance (advanced).
Check your PSU cable headers on the motherboard.
- Won't occur unless a PCI expansion card is installed. If installed, remove and reboot.
After POST your computer will continue to boot by activating the Basic Input Output System (BIOS).
- The BIOS is firmware, and works between your computer's hardware and software.
- It's permanently attached to the hardware.
- A battery retains settings for up to 10 years.
BIOS will attempt to boot your computer and run checks. As your computer was recently disassembled, it may request information.
It may ask to confirm hardware changes:
to set the date and time:
and launch operating system from the internal hard drive.
Your hard drive was wiped, so it cannot continue to boot.
Access 'System Configuration' so your computer can boot from USB to install our operating system. A well-timed keystroke is required. See keys on the 'splash' screen (bottom right):
- F9: Choose a device to boot from.
- F12: Force computer to boot from network card (advanced).
- F10: BIOS set-up. On your next reboot, press and hold F10.
BIOS Set up
Select 'System Information' from 'File' menu.
This displays information about the computer's components.
See Processor information from Workshop 01? See hardware without opening the case. Exit with any key.
Select 'Storage', then 'Device Configuration'.
Recognise your hard disk and DVD drive?
Exit and select 'Storage Options'. Enable 'Removable Media Boot' to allow booting from USB.
Exit and select 'Boot Order' to see available options.
We'll boot from USB, so move USB to the top.
Disable network booting if unneeded.
Confirm with F10 and exit Boot Order.
Return to 'File' menu. Select 'Save Changes and Exit'.
Confirm with F10. Your computer and boot process will restart, looking for the USB.
Boot From USB
You'll be given a USB containing a Xubuntu Live System and Installer. (A Live System lets you boot/use your computer from USB). We'll use this to install the Operating System (OS).
Insert USB and restart the computer (ctrl-alt-delete).
If successful, it should show a desktop environment with the install icon:
If not, check your BIOS settings and ask for assistance.
When ready, double-click the install icon.
Choose English, then 'Install Xubuntu'.
Confirm hard drive capacity and check 'install this third-party software' (this lets us use MP3s).
Select your hard disk, chose 'Erase and install', then 'Install now'.
Where are You?
Set your computer location (Brisbane), then continue.
Keep the default keyboard layout (English (US)) and click continue.
Provide your details and create a memorable password. Select 'log in automatically', then continue.
Your system will now install.
When complete, remove your USB and restart. Enter BIOS again and change your first boot device to internal hard disk.
SDLW Network Setup
Let's quickly set up our local SDLW network. We'll use it to update/install software without internet.
The facilitator laptop acts as a server to store your needed files. Your facilitator will show you this.
The Operating System
An Operating System (OS) looks after:
- Controlling peripherals
- Managing system resources - like the Central Process Unit (CPU) and the (GPU).
- Interacting with/storing files
- Communicating over networks
We just installed Xubuntu - a 'flavour' of Ubuntu based on Linux, a Free and Open Source OS.
In the top left you can access the whisker menu, (like Windows start menu).
Here you can access pre-installed programs and desktop settings.
Customising your Desktop
You can customise your desktop - eg, by right clicking image files to 'set as desktop background'.
You can also change theme. In the whisker menu, select 'settings' and select 'window manager'.
Select 'kokodi' - it has larger window handles for easier resizing.
The File Manager
The File Manager helps us navigate your system's files and folders. Select it from the whisker menu.
It will default to your home folder.
Try changing your view settings:
Note your file location within the computer in the top bar.
Choose 'Settings' from the whisker menu and select 'Software Updater'.
It will check for updates from the SDLW laptop.
Don't worry if some updates are missing - click 'install now'.
Enter your password - your system will update.
Restart your computer before the next workshop.
