Mount NTFS drives:
You may be having NTFS formatted partitions on your HDD. The stable ntfs-3g driver now allows Linux systems to read and write NTFS formatted partitions. The ntfs-3g packages comes pre-installed with the newest versions of Ubuntu, but you still need to install ntfs-config if you want the GUI configuration tool. Search for "ntfs-config" in Synaptic or install via terminal:

$ sudo apt-get install ntfs-config




Applications->System Tools->NTFS Configuration Tool



Mounting Windows partitions

You may manually mount/unmount partitions using following commands:

$ sudo mkdir -p /mnt/SOFTWARES
- /mnt/SOFTWARES is the mount point

$ sudo mount -t ntfs-3g /dev/sda5 /mnt/SOFTWARES -o force
- force parameter is used in case normal mount fails
- sda5 is the physical partition name given by linux

$ sudo umount /dev/sda5

To mount USB drives automatically on connection install "usbmount"

System->Preferences->Keyboard Shortcuts
You definitely want the "Windows" key to work. Ubuntu names this key as "Super".

For using a combination of the "windows key" and other keys e.g Win+r to open a "Run" dialog
System->Preferences->Keyboard->Layouts->Layout Options

Then while configuring Keyboard Shortcuts "Super" will appear as "Mod4". "Super" would not work by itself as earlier. It will only work in combinations e.g. <Mod4>r

For a more advanced configuration of keyboard shortcuts/commands 

$ gconf-editor
In apps->metacity->keybinding_commands you can make use of any of the empty commands e.g command_1, command_10 and enter the command you want to execute as the value.

Then in apps->metacity->global_keybindings enter the key combination for the command e.g run_command_1

To display the keyboard modifier map and keymap table 

$ xmodmap -pke
To get a description of every key press 
$ xev

The ALSA sound driver is provided by default.
System->Preferences->Sound



Video:
If you have a graphics card installed on your system, you may need to install the latest video drivers for it. Ubuntu provides the basic drivers for you. Specifically, if you have an HDTV hooked to your PC as a monitor then the screen just after installation may be misaligned.

System->Administration->Synaptic Package Manager
Search for the latest drivers. e.g. nvidia



The Synaptic package manager is a one-stop-shop for Linux softwares. Its similar to Add/Remove Programs in Windows but along with a search tool and a listing of a huge repository of Linux softwares. Installing Linux softwares is so easy and fast; no repetitive "Next" button clicks needed.

Enable the nVidia driver.
System->Administration->Hardware Drivers



Adjust the screen resolution.
System->Preferences->Screen Resolution

Just pop-in the CD and restart your computer. Experience the features Ubuntu has to offer. Following programs are pre-installed:
- Firefox 3 browser
- Evolution email client
- OpenOffice.org 2.4
- Transmission bittorrent client
- Brasero disc burning
- GIMP image editor

Installing Ubuntu is a breeze; its a quick and simple process. Here is an example of what your hard disk configuration should be like for installing Ubuntu.



Suppose you have 6 partitions on you HDD and the first partition is where your current operating system is, then Ubuntu can be installed in that first partition along with the current operating system or just by itself. Ubuntu needs 3 partitions to install itself:
- "/" partition
- "swap" partition
- "/home" partition

These 3 sub-partitions can be made inside the first partition mentioned above. Following are some really good tutorials to get you through:
Partitioning
Dual boot Windows with Linux - Windows installed first
