Unable to locate fs-pkg (NEWBIE)

Hi,

I installed QNX 6.2.1 using a CD-Rom drive as slave in the IDE cable. The
installation worked fine, and everthing boots and works well as long as the
CDRom drive is attached. Now, I need to take the CD-rom drive out, and when
I do it I get the following boot error. My HDD is still the master.

Detected EIDE. Scanning for devices.
/.diskroot file for root not found on any filesystem1
Unable to locate fs-pkg

Any recommendations?
Thanks.

PS: I’m a newbie, so detailed explations will be appriciated.
