Boot and Backup Data without OS on a Computer Before Format

Boot Backup Data without OSThis post explains how to boot and backup your data without OS on your computer before format. Yes, you can copy your files and folders from one partition to other partition, external disks or network share before format.

Let me ask a question, when your computer OS is not booting up or it can’t be repaired then what is the next step? Next step is simply format the partition and do a fresh installation or re install OS in different location.

But sometimes you will be in a situation to format the disk partition, so how about your files?  If you are an IT guy then usually we remove the hard disk, connect with other working computers and backup files, or connect with external hard drive cases and copy our files.

Here you can boot and backup data just by a CD without OS on your computer or removing and connecting disks. Let’s boot computer with Knoppix live CD and backup files before format. It’s very simple and easy method.  USB flash disks, external USB hard disks and network shares working fine with this method to copy your data without OS before format.

Follow the steps to boot a computer by CD without OS and access partitions.

1)      Download Knoppix live CD and write to a CD. DVD version is available here.

2)      Boot the computer with CD and Press Enter in first screen.

3)      Knoppix is a Linux OS, so you can see some Linux booting screens and auto detections of your computer hardware.

4)      Once completely booted you can see a full fledge OS which is running from CD without any installation.

5)      Accessing windows partitions in Knoppix is very simple. Normally all detected partitions will be appeared on desktop starting sda1,sda2 depends on how many physical drives and partitions available. In this example I have one partition which is showed in desktop.

    Worked fine for me too!!!

    I used Knoppix 6.2 and was able to recover data from a machine in which corrupted registry prevented Windows XP from starting.
