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.

am very new to linux... i installed mandriva 2007 and was amazed by its features.... but all of a sudden after 3 days am not able to boot into the linux....
it's telling "vfs: unable to find ext3 filesystem on hda8 "
and ending with the msg.. "kernerl panic: not syncing.Attempted to kill init"
but am able to boot into xp which is in my primary c drive..
do i need to reinstall??? or some other way is there??
For the Linux not booting issue looks like you have somehow deleted the partition or changed the type of it. Windows not booting could be because of some similar issue.
Recollect if you have changed any partition/filesystem related change u made recently on the system. Make use of rescue mode to get access of the partitions on the disk and see if you can mount them manually in rescue mode.
Mandriva Disk one probably can function as a rescue disk as well. Boot from CD and at the boot prompt type linux rescue. This is how most installer work, but I don't know Mandriva well enough to say for certain.
hd8 is a strange device. Usually it is hda or sda,depending on if it is ATA or SCSI. I assume you meant hda. /sbin/fdisk /dev/hda and then print the partition table. Do not make any changes to your partition table or you may screw your windows partition as well.
What do you have there?
My guess is something correupted either your /boot or / (root) partition.
I think there is something wrong with lilo configuration, Mandriva does not give you the option of using ext3 file system. It formats ext2 by default. If you installed the default boot loader it is lilo, you will have to search for knowledge on how to re-build lilo configuration with the installation disc, grub is an option as a boot loader in Mandriva and is easier/better to work with.
You must have used a different utility to format you root partition, because I tried everything to get ext3 when I installed Mandriva 2007 and it would not give me ext3, only ext2. Or...maybe it's because I used an existing partition that was not formatted, I did not use Mandriva to make the partition, only format it.
"No resume device specified
echo: cannot open /proc/suspend2/do_resume for write: 2
I still think it is a boot loader problem, although /etc/fstab may be involved, but according to the error I quoted above, there seems to be some problems with pointers to root and swap partition. If you installed the default boot loader, it is lilo, I changed mine to grub in the final configurations at the end of installation. I post my /boot/grub/menu.lst to show what it should look like in case you used grub also. When using the install disc in rescue, you should be able to look at your lilo.conf with command:
Or if you used grub:
Here is my /boot/grub/menu.lst:
color black/cyan yellow/cyan
kernel (hd0,0)/boot/vmlinuz root=/dev/sda1 resume=/dev/sda2 splash=silent vga=788
kernel (hd0,0)/boot/vmlinuz root=/dev/sda1 resume=/dev/sda2
kernel (hd0,0)/boot/vmlinuz root=/dev/sda1 failsafe resume=/dev/sda2
kernel (hd0,0)/boot/vmlinuz-2.6.17-11mdv root=/dev/sda1 resume=/dev/sda2 splash=silent vga=788
Notice in the first section called "title linux" it has "root=/dev/sda1 resume=/dev/sda2", this is reference to which partition is root and which is swap, the resume=/dev/sda2 is swap. Because according to the errors you posted, it cannot find the /boot sector of the root partition, which tells me it can't read /etc/fstab yet which is in the root partition.
Something tells me you're not mounted properly, you may have to include the directory in the command including the mount point, I have not had the opportunity (lucky me) yet to use rescue mode.
BUT: This link below looks like a simple, easy to understand tutorial on using the Mandriva CD in rescue mode. I would not be afraid to try the "Re-install bootloader" option, but that's me. You should give this article a good skimming over.
