Reset surface to default

Reference: Microsoft
Reset from the Windows sign-in screen

Notes

• If you’ve lost your password, you may not have to reset your Surface. See I forgot my password before
  performing these reset steps.
• If you don't have a keyboard connected to your Surface Pro or Surface 3, you'll need to use the on-screen keyboard to do these reset steps. From the Windows sign-in screen, tap or click the Ease of access icon in the lower-left corner of the screen, and then tap or click On-Screen Keyboard.

Step 1:	From the Windows sign-in screen, tap or click Power in the lower right corner of the sign-in screen.
Step 2:	Press and hold the Shift key. (If you're using the on-screen keyboard, tap or click the Shift key.)
Step 3:	While the Shift key is still pressed, tap or click Restart. If you get the prompt Restart anyway, tap or click Restart anyway. After Surface restarts, the Choose an option screen will appear.
Step 4:	Tap or click Troubleshoot.
Step 5:	Tap or click Reset your PC. Surface restarts and the Surface logo displays while Windows prepares to reset your Surface.
Step 6:	On the Reset your PC screen, tap or click Next.
Step 7:	Choose either Just remove my files or Fully clean the drive. The option to clean the drive is more secure, but takes much longer. For example, if you are recycling your Surface, you should choose to clean the drive. If you are keeping your Surface, you just need to remove your files.
Step 8:	Tap or click Reset. Surface restarts and the Surface logo displays while the reset process completes (this can take several minutes).

create usb boot with dd command

Format disk to fat32 before create usb boot
format fat32 command
sudo mkfs.vfat -I -F32 /dev/sdx
format NTFS
sudo mkfs.ntfs /dev/sdx
format ext4
sudo mkfs.ext4 -L label /dev/sdx
sudo mkfs.ext4 -F -O ^64bit -L 'Label disk' '/dev/sdx1'

#fdisk -l

#sudo umount /dev/sdc
#dd if=ubuntu-mate-14.04.2-LTS-desktop-i386.iso of=/dev/sdc bs=1M

แบบมี status ว่าทำได้กี่ %
1.ต้องติดตั้ง package pv dialog (sudo apt-get install pv dialog)

3. sudo dd if=file.iso |pv| sudo dd of=/dev/sdX bs=1M

* สามารถ Clone disk to disk ได้ด้วย
* dd มันอ่านข้อมูลเป็น block แล้วก้อปไปใส่อีกตัวตรงๆ
ถ้าไฟล์เล็กๆเยอะๆ dd จะไวกว่ามาก เพราะมันไม่สนจำนวนไฟล์ มันอ่านข้อมูลเป็น block จาก hdd เลย
ข้อเสียคือมันจะทำทั้งลูก ต่อให้มีข้อมูลอยู่ 1kb มันก็ทำทั้งลูกอยู่ดี
