I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps:

1. Created a primary partition(/dev/sda2) and format it as ext3 and set it as active.
2. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux
3. Then i installed the GRUB in boot/grub
4. Created the grub.conf in boot/grub

Following are the contents of each directory in the USB:

syslinux/

     boot.cat
     isolinux.bin
     splash.jpg
     vesamenu.c32
     initrd0.img
     ldlinux.sys
     syslinux.cfg
     vmlinuz0

LiveOS/

     livecd-iso-to-disk
     osmin.img
     squashfs.img

EFI/ boot/

     boot.conf
     grub.conf
     boot.efi
     bootia32.conf
     bootia32.efi
     splash.jpg
     splash.xpm.gz
     vesamenu.c32
     initrd0.img
     isolinux.bin
     isolinux.cfg
     vmlinuz0

boot/grub/

      core GRUB files
      grub.conf
  olpc.fth

Following are contents of grub.conf

default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu

title funLinux
kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img

Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said

No root device found Boot has failed, sleeping forever

So, where is the problem? what i am doing wrong?
