I had to reinstall windows on my roommates computer because of a virus. After the clean install i created an image of the system with clonezilla onto an external hard drive i had laying around. I wanted to put the image on a SD card but i didn't have one big enought laying around so i purchased one. Now i want to move the image over from the hard drive to the SD card but i can't figure out how to do it. I use linux. I tried copying the image and pasting it on to the SD card but that didn't work. i had write permisions on the SD card. I tried doing a dd if=/path/to/image of=/path/to/mounted/SD/card bs=512 and that didnt work. I tried asking this same question on the clonezilla forum but i havent received a response yet so i thought i would try another source of information. Any help or ideas would be greatly appreciated. Thanks.

Do you want to make a simple backup of the imagefile or do you want to copy the contents of that file to the SD card?
In the latter case you have to use clonezilla to do that.
In the first case a simple copy and paste should do the job. Keep in mind that most SD cards come pre-formatted with a FAT32 file-system (used by many cameras), but FAT32 has a limit on the file-size (max. 4GB per file), so if your imagefile is larger than 4GB you have to format the SD card with a better file-system first. I would recommend NTFS if the card should be readable by Windows and Linux systems or ext2/3/4 for Linux systems only.

Or use clonezilla to make it into files. (if not already)

Could use g4u which is dd plug gzip so you might compress it a bit.

I would have never made a backup as a clone. Dunno. I guess that is just me. I would have made it into files instead. Even on a clone by dd I make it into a single file usually.

The only time I clone is for drive to exact same size drive.

Note abusing tools like 'dd' can cause irreversible damage so best ensure you know what to do before you do. "of=/path/to/mounted/SD/card" is wrong if this represents a mounted partition. It should be a block device in /dev, the device should not have any partitions mounted, the device should represent the whole disk like "/dev/sde" and the command should be executed by the root user. (BTW, if you run '/usr/bin/pkill -USR1 -f 'dd if=';' in another terminal during the process you get progress details in the terminal 'dd' runs in.) Also note that unlike Linux, which loads drivers on the fly and not according to some rigid scheme determined at installation time, you may experience trouble loading your freshly copied Windows installation due to problems with the HAL. (BTW[1]: questions about that should be asked in the Non-*NIX General forum, not here.)
