debian recovery status

i have created the partitions on new drive and formated them (with fdisk)

/dev/hdb1 6.5G 3.5G 2.7G 57% /home/ubuntu/mnt/root
/dev/hdb5 30G 18G 11G 64% /home/ubuntu/mnt/opt
/dev/hda1 9.2G 3.6G 5.2G 41% /home/ubuntu/mnt/rootnew
/dev/hda3 56G 6.2G 47G 12% /home/ubuntu/mnt/optnew

now I'm waiting cp to finish
$cd /home/ubuntu/mnt/opt
$cp -rp * /home/ubuntu/mnt/opt

/dev/hda1 is the new root partition (/boot dir is there too)
all i did to install grub was
sudo grub
root (hd0,0)
setup (hd0,0)
quit

after that reboot with new driver
