DELL XPS702x - Win7 Home Premium installed on SSD Samsung 840 EVO - black screen with blinking cursor after POST

Hi, I have just removed 1 of 2 HDD installed in my Dell XPS L702x and replaced it with Samsung 840EVO 250GB drive. I have done fresh install of Windows 7 Home Premium on SSD using bootable pendrive and it went OK but after restart when Win7 trying to boot up for the first time - after the POST procedure - the screen remain black with a flashing cursor in the top left of my screen. I have already tried installing the same OS on the second HDD and it works OK. BIOS has been set to AHCI by default. Could anyone help me to solve this problem? Thank You Dariusz
