Hello !
I have a grub problem :
I resized a partition and now I boot directly into GNU grub rescue

if I type
sh:grub> linux /boot/vmlinuz-2.6.32-22-generic
sh:grub> initrd /boot/initrd.img-2.6.32-22.generic
sh:grub> boot
I have the following messages :

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
 - Check rootdelay= (did the system wait long enough?)
 - Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)

ALERT! does not exist. Dropping to a shell!

BusyBox v1.10.2 (Ubuntu 1:1.10.2-1ubuntu6) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Here is the /proc/cmdline I have
(initramfs) cat /proc/cmdline
I use Grub 2. I can boot via live CD.
I have a boot directory in one of my logical partition, grub doesn't seem to find it.
What can I do to boot ?
Could you give me some pointers ?
