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.

When I try to boot up into Ubuntu Linux, I get the error:
Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)
I think it's caused by the errors from an accidental power-off when the "Unmounting local filesystems..." part of the Linux shutdown sequence was running. Since I'm on a dual-boot with Windows XP, I checked PartitionMagic 8.0 to see what was up. There is an error on Ubuntu's ext3 partition that says the partition's beginning is overlapping with the previous partition (in Ubuntu, /dev/hda1 is Windows NTFS, /dev/hda2 is Linux ext3, /dev/hda3 is Linux swap). Is there any way I can repair this drive at all, from a bootable floppy/CD or Windows? Would any sort of reformatting or repartitioning help, and in doing so, could I save my Windows partition?
I have already tried the disk diagnostic programs for my hard drive.
The only other cause of this problem that I can think of is my installation of a 686 kernel package...but I would assume that ext3 support is contained in this update. Even if it isn't, wouldn't the error message be different if the filesystem was unrecognizable?
What sort of program should I use to do that? Could I use fdisk (does that have partition resize capabilities) or some other program in Knoppix? PartitionMagic won't even touch the physical drive.
Also, does resizing a partition only resize it from its end? I can't resize the NTFS partition in Linux, and no matter how I resize the Linux partition, its beginning will always have a conflict with the end of the previous one...I guess I'll try running the disk diagnostic program again.

PartitionMagic won't do the job because there are errors on the disk. When I first ran it, it gave me an info box asking me if I wanted to repair the damage and I clicked "OK" or "Yes", but sadly it did not fix the error and now the physical C: drive is "BAD" and I can't perform any partition functions on it. I'm thinking of just deleting the Linux partition and starting over (I only had it for 2 days anyways). But I really don't wanna do everything over again...any other options?
