After installing Ubuntu 14.04, my Windows 8.1 and Ubuntu cannot boot anymore, I get the message below, please help me fix it as I cannot use my computer any more. I tried to install boot repair through live Ubuntu CD to fix it but I cannot install it.

I appreciate your help and looking forward to hearing from you.

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/xxxxxxxxx does not exist. Dropping to a shell! 
BusyBox v.1.21.1 (ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash) 
Enter 'help' for list of built-in commands .

By default, Ubuntu installs using a legacy BIOS type boot sequence, whereas Windows 8 is most likely booting via EFI. Try interrupting the bootup on your machine with the appropriate key (F10, F9, F12, F2, or whatever it is on your particular model of pc) and selecting the Windows boot loader there rather than letting GRUB take control. By the time GRUB loads, the boot sequence has come too far to boot Windows 8.
