From what i can learn it doesn't look possible to boot from an SD card on your laptop, but it looks like you can boot from a usb device .
You can try getting into the boot menu at startup and see if the SD card is listed as a boot option if not then it looks like it's not possible
To access the boot menu try the following instructions
restart the computer.
Press the "Esc" key when the "Press the ESC key for StartupMenu" message appears on-screen. This message will come on while the Compaq logo is on-sceen.
Press the "F10" key when the Startup Menu appears on-screen to enter the Setup Utility Program.
Use the arrow keys to select the "System ConfigurationMenu."
Use the arrow keys to go to "Boot Options."
