Asked by hey vj

I have installed Ubuntu 15.04 on my laptop. I want to make an image of it and install on another laptop.
Tried the below tools but no success so far. please help.

1. Symantec Ghost - is it available now for ubuntu?

2. DD Linux Command

dd if=/dev/sda1 of=./bak/sda1_bk.img bs=4096 conv=noerror, sync

The source file /dev/sda1 is only 8 GB size, but the target image file is keep growing even beyond 80 GB. not sure how it will work?

3. Clonezilla (Open source)

http://clonezilla.org/

Installed Clonezilla. Tried to make the image but it errors as

Error! No existing partitions(s) or no unmounted partition(s) are found! To use Clonezilla to save or clone a partition, the source partition must exist or be unmounted! If you are sure the partition exists in this machine, maybe the kernel is too old?

4. Fog (Open source)

https://www.fogproject.org/

Installed but not able to do the image.

5. Partimage (Open source)

Installed it. Tried but errors out as

Can't read bitmap block 0 from image

6. Acronis true image - available only for windows and mac

You will need to use a live CD desktop so that the source is unmounted. You can then use dd. You will need a writable partition of greater or equal size of the source to hold the image. This is one reason why a separate root partition is advantageous.

You can then use the same command, just reversed to put the data onto the destination system (you will need to partition the drive in a similar way. You may also have to instate GRUB and / or tweak the fstab to reflect UUIDs of the partitions.

Can you help with this problem?
