Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

what i actually did was i partitioned and formatted my usb (i thought) and then moved to my student room where i have plug in internet because i couldn't get wireless going. (driver problems i think because the blue light won't go on when i turn the switch on) When i arrived at my room i started up and it said the hard disk wasn't a bootable disk...
I opened ubuntu from live cd and couldn't find the disk any more. it was just gone. with a copied vista cd i managed to see that everything was gone. 150GB of free space....
anyone know if i was actually formatting my hard drive instead of my usb stick maybe? and anyone know if it's still possible to recover any of my lost data? (even windows is gone, no recovery cd's either )
I don't know if we can reconstruct what you did. During installation (of anything), there are a series of steps where you have to make decisions--eg which drive to use, how many partitions, to make, etc.
First, if there is any important data at stake, do not do anything that would write to the harddrive.
To see the current situation, boot up from the live CD and run "sudo fdisk -l". Post the results here. Also, try to reconstruct what steps you took and what choices you made.
also i just realized that i now have 2 partitions on my usb of which one is called casper-rw, which is 6,5GB of free space, but i can't save anything to and i cannot read the folder called lost&found or something. and the other partition only has 45MB of free space ...
It seems that the 160GB (sda) is your harddrive and that the 8GB (sdb) is the pen drive. It seems that windows is intact on sda1 and sda2, and that Linux is on sdb2. Not sure about sdb1.
The way you describe the usb drive, it is not appearing here---presumably because it was not mounted when you did fdisk -l.
If you have important data on the Windows partitions, then the first thing to do is get Windows working again. This requires some kind of bootable CD (eg a Windows install or rescue Cd or some third party utility disk) which you then use to restore the Windows bootloader.
If you have no access to a Windows CD, then search on Google using something like "restore MBR".
Once you get Windows working, backup your data. Then go back and install Linux.
You really think windows is still intact? because it showed an even amount of free space as total space when i used a windows cd... it couldn't install though, don't know why, it was a copied version, maybe that was it... don't know.
and what exactly will this command file -sL do? because i've become a little wary of the terminal
(btw you can call me a retarded noob, it's true ... )
ubuntu@ubuntu:~$ sudo file -sL /dev/sda1
/dev/sda1: x86 boot sector, code offset 0x52, OEM-ID "NTFS ", sectors/cluster 8, reserved sectors 0, Media descriptor 0xf8, heads 54, hidden sectors 63, dos < 4.0 BootSector (0x80)
ubuntu@ubuntu:~$ sudo file -sL /dev/sda2
/dev/sda2: Linux rev 1.0 ext2 filesystem data (mounted or unclean) (large files)
edit: i am starting to think that i have made a typing error when formatting or partitioning. you know sda2 instead of sdb2... because both sda2 as sdb2 have the label casper-rw...
i opened QParted and found this warning on sda2 "unable to find mountpoint. unable to read the contents of this filesystem! because of this some operations may be unavailable."
what also is still bothering me is why is my usb partitioned into one part that's 700MB and one called casper-rw that's 7GB on which i can't put anything?
