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"

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

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

$ xev

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.

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

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:
