+
+Creating a bootable qemu image from a root filesystem and bootloader
+
+1. Create a hard disk image
+
+<pre>qemu-img create -f qcow <imagename.img> <size>G</pre>
+
+2. Use a live CD (better to have a lighter OS like system rescue CD to make the process faster) and the image created to boot.
+
+<pre>qemu -cdrom /dev/cdrom -hda <imagename.img> -boot d</pre>
+
+3. Once system is booted use a partition editing tool (like fdisk, cfdisk, parted, gparted, qtparted ...) to partition the image.
+
+<pre>cfdisk</pre>
+
+create the necessary partitions (root and swap partitions boot, home ... if required)
+
+4. Create a file syatem for the root partiotion
+
+<pre>mke2fs /dev/hda1</pre>
+
+5. Mount the partition 
+
+<pre>mkdir disk
+mount /dev/hda1 disk</pre>
+
+6. Copy the file system from the host machine to the mounted directory (use a compressed file system to make the copying faster)
+
+Grab the GNU spapshot from ams' site <http://www.update.uu.se/~ams/home/slask/GNU/>
+
+<pre>scp <user>@<host>:<path to the compressed file system> disk</pre>
+
+7. Uncompress the files
+
+<pre>cd disk
+tar -jxvf <compressed filesystem></pre>
+
+8. Unmount the mounted partition
+
+<pre>cd .. 
+umount disk</pre>
+
+9. power off the guest OS.
+
+<pre>poweroff</pre>
+
+10. To make the file syatem bootable download a grub floppy image ([[http://hurd.in/pub/Hurd/HurdOnVMware/grub.img][grub.img]])
+
+11. Run qemu to boot into your brand new system 
+
+<pre>qemu -hda <hard disk image.img> -fda grub.img -boot a</pre>
+
+Happy Hacking !!
+
+
+Make your new system boot from the hard disk
+
+1. Mount your grub image
+
+<pre>mkdir floppy
+mount -t ext2 -o loop grub.img floppy</pre>
+
+2. Use previous steps 2 and 5 to boot from a liveCD and mount the partition
+
+<pre>cd disk/boot
+scp -r <user>@<host>:<path to mounted floppy image directory>/boot/grub .</pre>
+
+3. Poweroff the guest
+
+<pre>poweroff</pre>
+
+4. Boot new system using floppy image previous step 11
+
+use install to hard disk option if you used the above grub image
+
+or go to grub command line and type
+
+<pre>root (hd0,0)
+setup (hd0) </pre>
+
+Now you have a bootable system image. Enjoy Maadi !!
