Install LFS livecd to harddisk

1. Boot from an existing Linux distro or any live-cd
2. Download the LFS LiveCD iso from http://www.linuxfromscratch.org/livecd/download.html
3. Use exist Partition or make a  new Partition of your harddisk (ERASING ALL DATA) with the command echo ",,b,*" | sfdisk /dev/sdX  or we will know tool
   
   
   
   1. sdX should be replaced with the block device name of your harddisk (sda1 or hda1)
4. Format the newly partitioned disk with mkfs.ext2 /dev/sdX1
5. Create a folder for mounting the new disk with mkdir /mnt/lfs-hd
6. Mount the new partition with mount /dev/sdX1 /mnt/lfs-hd
7. Create a directory to mount the LFS LiveCD iso with the command mkdir /mnt/iso
8. Mount the iso with the command mount -o ro,loop lfslivecd-x86-6.3-r2160.iso /mnt/iso
   
   
   
   1. Change lfslivecd-x86-6.3-r2160.iso to match the iso file you downloaded
9. mkdir /mnt/lfs-hd/boot
10. cp /mnt/iso/boot/isolinux/linux /mnt/lfs-hd/boot
11. cp /mnt/iso/boot/isolinux/initramfs_data.cpio.gz /mnt/lfs-hd/boot
12. Create a folder for mounting the root.ext2 ( It is compressed ext2 filesystem it will uncompressed to RAM and run as live lfs-cd ) with mkdir /mnt/rootfs
13. Mount root.ext2 to /mnt/rootfs
    
    
    
    1. mount /mnt/iso/root.ext2 /mnt/rootfs -o loop 
14.  Copy /mnt/rootfs file and folders to /mnt/lfs-hd
1. cp -Rvf /mnt/rootfs/* /mnt/lfs-hd
15. Use exist Linux grub bootloader file form step 17 or Create folder for bootloder
1. mkdir /mnt/lfs-hd/boot/grub
   
16. Copy  stage1,stage2,fat_stage1_5 /mnt/lfs-hd/boot/grub

kernel /boot/linux root=/dev/sdaX
initrd /boot/initramfs_data.cpio.gz


    

    title Windows
    rootnoverify (hd0,0)
    chainloader +1

    
    
    
    1. Replace sdaX with your lfs harddisk some PC have hdaX (x is partition number).
       
18. Unmount your harddisk with umount /mnt/sdaX
19. Start grub with the command grub
