Actually not the grub, the one is error. That code message, appear after I chose one of the option on the grub.

Here's the full error message
<code>
udevadm trigger is not permitted while udev is unconfigured.
udevadm settle is not permitted while udev is unconfigured.
svgalib: cannot open /dev/mem

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!
 /dev/disk/by-uuid/a..................................... does not exist

Problem solved:

The work around is following (thanks to <slangasek>)
(re)Start computer
If you have grub2 installed, you need to hold down the shift key while booting. If you have grub1 installed, you need to hit escape.
Now you can select the older kernel version from the grub menu
The system will boot normally.
Now open a console and run root command:
sudo update-initramfs -u
that will regenerate the initramfs for the newest kernel,
and after reboot all will work in the newest kernel also.
