EasyBCD w/ Win 7 recovery CD does ot recognize hard drive

according NeoSmart instructions, I created a 'live' EasyBCD/Win 7 recovery on a thumb drive. I even have a backup of the boot-sector (made with EasyBCD) of the PC to repair. In the BIOS the hard drive in question is visible, EasyBCD starts up until the GUI, but when trying to recover it does not recognize any drive on the PC. Any idea what I could possibly have done wrong?:confused: Thanks in advance for every hint to solve the issue!!:smile:
