Greetings everyone

I am really left off right now. I wanted to expand the size of my OSX partition so i made an image of it using Disk Utility from iDeneb 10.5.5 disk (i booted and opened the Disk Utility) and that created a DMG image file which i saved to another HFS+ partition on the same drive.

I deleted the OSX partition and reformated it with osx extended journaled and booted again with iDeneb 10.5.5 to restore the partition image to the newly formated mac os extended journaled partition. I select the DMG and as destination the new partition, click restore and BOOM, the disk utility says:

Could not validate source - error 254

What can i do? I've encountered the same error message before when trying to restore a vanilla OSX dvd to a hard drive partition. I never figured out why this is happening and im really left off right now because i have valuable files into this partition (which seems to be just a DMG file now..)

Im desperately seeking for assistance
