Failed OS installation on SDHC card

I really need help on step 1: installing the image on an SDHC card (Sandisk 16GB). It is a proven SDHC card and card reader/writer. The card reader/writer formats the SDHC card on the particular USB port just fine. The error log indicates something about Preparing phase being problematic. Is it perhaps a SDHC card issue? I have tried a number of different USB ports as well. Any help will be appreciated.
