[Ubuntu] Error: The disk drive for /media/sda2 is not ready yet or not present

After updated Ubuntu, and reboot, I got these error

The disk drive for /media/sda2 is not ready yet or not present.
Continue to wait, press S to skip or M for manual recovery.

Though I can press s to continue the starting, but that is not so good to do that.

Then i google these.

From here: http://ubuntuforums.org/showthread.php?t=1466555

I found the solution.

First, I use blkid to check the device list

sudo blkid

I got these message

/dev/sda1: LABEL="M-gM-3M-;M-gM-;M-^_M-dM-?M-^]M-gM-^UM-^Y" UUID="AC6849A96849735E" TYPE="ntfs"
/dev/sda2: UUID="1E14506314503FC7" TYPE="ntfs"
/dev/sda5: LABEL="My Documents" UUID="BA768C1F768BDA91" TYPE="ntfs"
/dev/sda6: UUID="95f5cc90-1136-4380-9aa7-cf3081ed5fd1" TYPE="swap"
/dev/sda7: UUID="4f351c19-b8cb-4045-b912-1b2a0bb0101a" TYPE="ext4"

Then open the fstab

sudo vim /etc/fstab

Here is the content

# /etc/fstab: static file system information.

You can the that the RED code, compare to the list of blkid, i DO NOT have these UUID devices

So, I remove these two lines, save, then reboot the system.

Fixed!

Have fun with Ubuntu!
