Copy Your Linux Install to a Different Partition or Drive
If you need to move your Linux installation to a different hard drive or partition (and keep it working) and your distro uses grub this tech tip is what you need.
To start, get a live CD and boot into it. I prefer Ubuntu for things like this. It has Gparted. Now follow the steps outlined below.
- Mount both your source and destination partitions.
Run this command from a terminal:
$ sudo cp -afv /path/to/source/* /path/to/destinationDon’t forget the asterisk after the source path.
- After the command finishes copying, shut down, remove the source drive, and boot the live CD again.
- Mount your destination drive (or partition).
- Run the command “gksu gedit” (or use nano or vi).
Edit the file /etc/fstab. Change the UUID or device entry with
the mount point / (the root partition) to your new drive.
You can find your new drive’s (or partition’s) UUID with this
$ ls -l /dev/disk/by-uuid/
- Edit the file /boot/grub/menu.lst. Change the UUID of the appropriate entries at the bottom of the file to the new one.
- Run sudo grub.
At the Grub prompt, type:
find /boot/grub/menu.lstThis will tell you what your new drive and partition’s number is. (Something like hd(0,0))
root hd(0,0)but replace "hd(0,0)" with your partition’s number from above.
setup hd(0)but replace "hd(0)" with your drive's number from above. (Omit the comma and the number after it).
That’s it! You should now have a bootable working copy of your source drive on your destination drive! You can use this to move to a different drive, partition, or filesystem.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
