 ====== Copy Linux to a new Harddisk ======
+In the following howto i assume that sda is your source drive and sdb is your target drive.. please make sure not to mix this up in your setup! also i assume that your operating system disk has three partitions, sda1 as /boot, sda2 as swap and sda3 as /
-  * stop any running services like apache, mysql etc. on the source system.
+  * stop any running services like apache, mysql etc. on the source system. or even better, boot from a live linux and work from there..
   * partition and format the new harddisk
-  * rsync - for each partition
+    * parted /dev/sda --> print shows the current partitions of sda including their sizes.. that should help :)
-  * edit fstab and /boot/grub/menu.lst and update UUID according to [[harddisks_by_uuid_in_debian_lenny]]
+  * create mountpoints for source and target <code>mkdir /tmp/source
-  * install grub
+mkdir /tmp/target</code>
-  sudo grub
+  * mount source and targed partitions: <code>
-  find /boot/grub/menulst
+mount /dev/sda3 /tmp/source
-(if you have an own partiton for boot, you can leave boot away in the above command)
+mount /dev/sda1 /tmp/source/boot
-  root (hd0,0)
+mount /dev/sdb3 /tmp/target
-  setup (hd0)
+mkdir /tmp/target/boot
+mount /dev/sdb1 /tmp/target/boot
+</code>
+  * now copy the os: <code>rsync -aHvx --numeric-ids /tmp/source /tmp/target</code>
+  * edit /tmp/target/etc/fstab and /tmp/target/boot/grub/menu.lst and update UUID according to [[harddisks_by_uuid_in_debian_lenny]]
+  * chroot to the target drive and install grub: <code>
+mount --bind /dev/ /tmp/target/dev
+mount --bind /sys/ /tmp/target/sys
+mount --bind /proc/ /tmp/target/proc
+chroot /tmp/target
+grub-install /dev/sdb
+update-grub
+grub
+find /boot/grub/menulst</code>(if you have an own partiton for boot, you can leave boot away in the above command) <code>
+root (hd0,0)
+setup (hd0)
+</code>
   * reboot your system
