Putting Ultimate Boot CD on USB Flash Drive

If you're buying a Linux/Mac laptop without a built-in optical drive, it is impractical to bring along an external optical drive for running Ultimate Boot CD (UBCD) just to check for defective pixels on the LCD screen. The solution is to put UBCD on a USB flash drive with at least 114MB of free space .

1. Download ubcd411.iso and burn it to a CD.
2. Test booting the CD to make sure it works.
   
3. Copy all the contents of CD to the USB flash drive.
4. Download syslinux-3.36.zip and unzip the files to c:\syslinux
   
5. Click Start -> Run & type cmd.
6. Type cd c:\syslinux\win32
7. Type syslinux -ma u: (replace u with your USB flash drive letter) to make the drive bootable.
8. Restart computer and set your BIOS to boot from your USB flash drive.
9. Select Mainboard Tools, Peripherals Tools & CHZ Monitor-Test

For Windows laptop, you can run Dead Pixel Buddy or UD Pix directly from the USB flash drive without installation.
