Repairing GRUB UEFI Dual Boot Debian 7.1 x64 and Windows 8 x64

Accidentally I failed to install AMD Catalyst 13.6 beta on my Debian 7.1 x64, and I lost my GNOME. For short, I can't recover my GNOME and I reinstall my Debian 7.1 without EFI mood  (my mistake). The Installer can not detect EFI and the only option to install bootstrap loader is MBR.

I can not start both my Debian and Windows. From Bios, I start boot via EFI DVD to start Debian CD Installer. I choose Advanced Option to fix bootstrap location from MBR to EFI Partition (System Reserved), and follow these step:

1. Update your Debian and run
   
   # apt-get install grub-efi-amd64
   
   This command will remove grub package, and choose yes
2. Configure your GRUB using this command
   
   # modprobe dm-mod
   # grub-install
3. Apply your new grub into EFI Partition
   
   # update-grub
4. This procedure only fix boot into Debian. To create boot option to load Windows 8 boot manager you need UUID for EFI partition by running
   
   # blkid
   
   write down UUID for EFI Partition (it may be label as "System Reserved") with size about 100M-130M.
   for my case UUID is 4842-E4F1
5. edit file /etc/grub.d/40_custom and at the end of file add
   
        menuentry "Microsoft Windows 8" {
          insmod part_gpt
          insmod fat
          insmod search_fs_uuid
          insmod chain
          search --fs-uuid --no-floppy --set=root 4842-E4F1
          chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
        }
   
   the file becomes like this:
   
        #!/bin/sh
        exec tail -n +3 $0
        # This file provides an easy way to add custom menu entries.  Simply type the
        # menu entries you want to add after this comment.  Be careful not to change
        # the 'exec tail' line above.
        menuentry "Microsoft Windows 8" {
          insmod part_gpt
          insmod fat
          insmod search_fs_uuid
          insmod chain
          search --fs-uuid --no-floppy --set=root 4842-E4F1
          chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
        }
6. reinstall and reconfigure your grub by issuing :
   
   # grub-install
   # update-grub

Done, now I have GRUB to my Debian and option to load Windows 8 Boot Manager

How to install Raspbian Wheezy to SD Card for Raspberry-pi using Debian Machine

Raspberry-pi is a community product for System On Chip (SOC). It's uses ARM Processor with low power usage. We can say, it's absolutely green computing. Unfortunately, the performance was poor, may be we can find more powerful 4, 6 or 8 core ARM with low power usage. 

This is how I install raspbian on raspberry-pi:

1. Download raspbian form official site http://www.raspberrypi.org/downloads/
2. From Debian open terminal as a root privilage
3. If you dont't have image writer to SD-Card, install this pacakge first # apt-get install dcfldd
4. Insert your SD-Card and find out where it's mounted by your Debian
   # dmesg
   [  995.384415] mmc0: new high speed SDHC card at address aaaa
   [  995.384943] mmcblk0: mmc0:aaaa SU08G 7.40 GiB
   [  995.390744]  mmcblk0: p1
5. Unmount SD Card
   # umount /dev/mmcblk0
   umount: /dev/mmcblk0: not mounted
6. Copy your Raspbian image into SD Card
   # dcfldd bs=4M if=[folder_input_file]/2013-09-25-wheezy-raspbian.img of=/dev/mmcblk0
7. Make sure the SD-Card is writen properly
   # sync

Note:

Copying image may take a long time, it's size up to 2.96Gigabyte
