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.

I'm new to Linux, and I'm having some trouble with installation. I recently downloaded and installed Lubuntu 12.10 on my computer. During the installation procedure, the installer detected that I had Windows XP Home Edition installed on the hard drive, and offered me the option of installing Lubuntu alongside it, so that I would be able to choose which OS to start when starting the computer. Installation finished without a hitch, but when I tried to get back into Windows XP, I got the following error:
"A disk read error has occurred.
Press Ctrl-Alt-Delete to restart."
All the files from my Windows installation are still there; I can still open Word documents and edit them, save them, etc. In an attempt to fix this, I did some searching, and found a tool called "Boot-Repair" for Ubuntu. I clicked the "Recommended repair" button, restarted the computer, and tried again to boot into XP, and got the same error message as above.
I then did a Google search for how to uninstall Lubuntu. From what I gather, the standard way of doing it is removing the hard drive partitions that have Linux, and then going into the Windows XP Recovery Console and doing a "fixmbr" and "fixboot." Tried all that, got the same error.
Then, I found this article through a Google search, which suggested deleting boot.ini, doing "bootcfg /rebuild," and then doing "fixboot" again to write a new bootsector. No success.
I don't know what else to try. I'm currently posting this from the Lubuntu 12.10 Live CD, because I can't boot back into Windows, and I removed the Linux partitions using GParted. (That reminds me: I also resized my Windows partition to take up the rest of the drive.) Again, I just want to stress that it appears there's nothing wrong with the files or the drive itself, it's just that I can't boot back into Windows. Anyone have any other suggestions?
By the way, here are my system specs (just in case they would help...):
The computer is an HP Pavilion a530n; 512 MB of RAM; 2.00 GHz AMD Athlon 64 processor; 200 GB hard drive; CD-ROM drive; DVD drive/CD-DVD writer.
Thank you for the quick reply!

I then did a Google search for how to uninstall Lubuntu.
You don't uninstall operating systems. You reformat the partition(s) they are on an install something else over them.
From what I gather, the standard way of doing it is removing the hard drive partitions that have Linux,
And you now know that wasn't right. Do yourself a favor and note the sites where you got this information and AVOID them in the future. You need to repair the windows bootloader FIRST and then re-format the partitions.
You said you can still view your windows files so everything is there and you have the standard boot files for xp as shown in the bootinfoscript. You wouldn't happen to have the xp installation disk? I've never actually used xp but have read about it and it seems in this situation you may need it as the files to reapir the bootloader may not be on a Recovery disk. The microsoft site below has some info on the problem but it isn't clear to me what they are referring to by 'Recovery Console' but it doesn't seem to mean the same as Recovery Disk? Someone else more familiar with xp should come along with more advice.
I'm sorry, yancek. Like I said, I'm still relatively new to Linux.
I tried Microsoft's suggestion of doing "fixmbr \device\harddisk0," but it didn't work.
Should I try restoring the MBR using Boot-Repair?
I would start over rather than waste more time trying to fix xp. The recovery option takes forever and has never worked for me. The most likely reason it is corupted is when ever you make partition changes with a second system, you need to reboot xp so it updates to the new configuration tables. Especially when ntfs file systems are changed.
Use the live cd to create a second partition, and move your to it.
The safest way to dual boot is use two hard drives, install xp on one first, then linux on the second drive. I asl recommend to create a small 50MB primary partion at the start of the linux drive and install grub legacy as a boot manager. If things go wrong, you just unplug the linux drive and it should reboot alone, as the loader is in the mbr unchanged.
With one drive the linux system will overwrite the xp mbr.
I do have a spare internal hard drive, but the problem is that my computer doesn't appear to have a place to install a secondary drive. Is there a safe way to install a second internal hard drive when there isn't a place to install another drive?
Also, are you saying that if I use GParted to create a new partition and move all my XP files into that partition, that I'll at least be able to save my data?
