I install new linux in sda and try to recover the boot partition in sdb I mount it /dev/sdb1 /bootpartion but I can't chroot into it and grub-install Can you help [root@host ~]# chroot /bootpartion chroot: cannot run command `/bin/bash': No such file or directory

When you chroot /bootpartion, it does not see /bin anymore... You need bash inside, and proc and dev too I guess.

you need to mount the ROOT directory, then mount the /boot partition under that. assuming / is /dev/sdb2 and /boot is /dev/sdb1

# mount /dev/sdb2 /rootdir # mount /dev/sdb1 /rootdir/boot # chroot /rootdir
