Transferring entire OS to another drive

[Jorge Boscan]

Hi Eric

Well, you ca do it many ways as you pointed out, dd is an option, to
copy all, as well
you must care about partitions order, fs type, in the end 3 files must
be correct

/etc/fstab
/boot/initrd.img
/boot/grub/grub.conf

the other thing to consider is grub you must install the boot loader
in the new drive

so what I would do is:

plug & mount the new-drive

create & format partitions (gparted)

copy all to the new partitions

chroot to the new-drive / filesystem

if nessesary edit fstab

run grub-install

and if after all, the new drive doesnt boot because boot loader
problems, you can boot with
a live-cd chroot and fix.

I hope I helped.
