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.

Hello,i have a problem with one hard disk,now it says its Unallocated,and i tried to create a new partition on it,but it says that first i need to create a partition table,but when i create one,choosing msdos label,it doesnt to nothing. I used Gparted in Fedora,how can i create a partition table,so i can use my hard disk again?
Well because i dont know what laber to choose ...so i let the default label..and when i give it to create partition table it says "Searching /dev/sda devices..." and thne it stops,wih no result,i also used fdisk...nothing
should create a new msdos label and a partition of size 10000 MB on /dev/sdb. Make sure that /dev/sdb is indeed the hdd you want to install on. Also make sure that there is no important data on /dev/sdb since it will be destroyed (the data that is, not the hdd itself).
Afterwards you can format the newly created partition /dev/sdb1 with mke2fs.
(1) Some distros, like those from the Red Hat family, are keen with booting to a label and dislike the normal device name like /dev/sdax. They would create labels as this page in cfdisk shows. The labels can get complicated as more digits have to add to make each one unique.

In my old box with 145 operating systems the labels used are
If I have a need to alter a Grub I always change the label back to the normal device name. Can't remember seeing Lilo using label on a Linux though.
(2) The Parted sofware uses "label" to distinguish the two partitioning schemes of "msdos" and "gpt". That is just using label for a different reason. 99% of us use only the msdos disk. gpt disks are not detectable by many Linux software and can't be booted by most Windows. Only 64-bit version Windows can boot a gpt disk and this can only be done with efi hardware in the mobo. Linux can boot gpt disks a long time ago. It is only used for partitions and hard disks larger than 2TB at the moment but can have 128 partitions maximum.
