Bootable usb stick + dd

eviltoaster · 03-16-2010, 05:00 AM

Hi, i have two usb sticks one at 8GB and one at 2GB. on my 8GB there is a 1.1GB of files that i need to clone to get my 2GB to work and boot as my 8GB. The biggest problem is how do i clone MBR? i know how to do it with dd but not when there is two different sizes.
if this is the problem. all i get at boot is GRUB nothing more, no menu or grub config screen. only the text "grub".

8GB usb stick with debian(1.1GB)
2GB usb stick empty

what i have done.

dd + no=trunc
dd files to image.dd
dd mbr
changed partition tables
dd only partition 1
and so on...

Reduce the size of the partition on the 8GB stick to 2 GB
Then dd that partition to the 2GB stick

I believe he means it failed to boot with the cloned drive.

Which four letters? G-R-U-B? is it a blank grub screen?
