Pogoplug e02 boot into rescue:~# after login, please help to reinstall debian (8 replies)

hi, I have a pogoplug e02 that had debian installed. But the flash drive was dead. I was thinking to reinstall debian by following the Pogoplug E02 Debian Linux Installation Guide. without usb attached, the Pogoplug E02 boot into "rescue:~# " after I type in root/root (user/password).
it's like this:

rescue:~#

As an linux newbie, I have been puzzled by "rescue:~# " for a long time. I was stuck and don't know what to do. Please help me out. BTW, I tried to ignore the "rescue:~# " thing and install the uboot. But I run into the following error message.

Please help me out, bodhi. I want to get out of "rescue:~# " and boot into "root:~# " after I input the user/password and re-install debian by following debian pogoplug installation guide.

Thanks
