With various tools such as Kadischi, linux live script, Ubuntu Customization Kit etc, you can easily come out your own live cd. What you required is just the matter of time to fine tune and customized your software included in your live cd.
There are so many questions around the live cd. What have linux live cd capable of? Which linux live cd is the best? How do you efficiently use it? I have my own answer, I think who have created its own live cd, or actually using it would have his story to tell.
Let me tell you my story, with some linux commands examples, that I used along with live cd during investigation and repairing windows machine.
What linux live cd I use?
The reasons I like slax are it is small in size. I usually ask the person who own the ‘problems’ windows machine to download and burn it for me on the spot. After done using it, I just ask them to keep the cd, which uses this way I promote them to use linux. ( Certainly, it fails. But at least they have aware of the alternatives that are better and strong.)
The second reason, it auto mount all the partitions it detects to /mnt/. So that I have no worries of mounting it myself, except mouting external devices such as USB flash disk.
How Slax come to rescue?
So, when windows couldn’t boot up, they called me. All the windows expert around the neighborhood had tried to help. Case 1, windows couldn’t boot up, not even load up with safe mode. Reinstall windows? Have tried to load up windows installer. The install refuse to reinstall and suggest to reformat the hardisk entirely. “OMG! orz my thesis forgot to backup! It is already 90% done” It is really cannot afford to loose it. Case 2, windows resist to boot up, not even showing any errors and windows installer couldn’t load up as well.
With this two cases, I ask them to download Slax iso from the website. Of course, Slax was successfully loaded. They are amazed, and start to ask what is Slax, its my call to introduce them what is Linux and what is live cd.
Ask them where they store their data? Assume it is stored at second partition which was mounted at /mnt/hda2. Next I list the mounted directories, trying to search for the files to backup. Things doesn’t goes so smooth, the hardisk is half corrupted. When I do
It hangs there…
Okay it is not so bad, because certain directories still can be list, but it took very long and its messy to pin point all the files. To see all the files listed and backup for those can be recovered and needed, I need to store all the list results into a text file, so I do this
ls -lR /mnt/hda2/* > hda2.txt
It took sometimes, but when It is done, I obtained the recoverable list of files, hda2.txt. With that now I can backup! I have my notebook with me, which I have my ssh server installed. Therefore I use scp to copy over the file over the LAN. Another option is to plugin the flash disk and backup.
scp -r /mnt/hda2/thesis email@example.com:~/backup
Another case was not so lucky, the partition are gone, same things goes to assignment. The partition causes windows installer fails to boot up. Therefore, remove the partition with fdisk.
Press m for all the options, list the partition with l, delete with d. To comfirm your changes, write with w, to quit without saving changes with q.
Pretty straight forward, and after doing that, windows installer booting up. I am not trying to criticizes Microsoft operating system or windows users. I am here to show you that what linux live cd capable of, and how you can use it for your system diagnosis, and repairs with just few simple commands.
There are plenty good live cd, again, check out frozentech.com.
