QNX Install from boot

I’ve been trying to Install QNX6.2.1A on 64MB Hard Drive. Using a USB DVD/RW/R/CD drive to install from the CD. After the “Hit Esc to .altboot”, “Press Space for more input options”, and “Scanning for IDE Devices”, I keep getting the error “No QNX 6.1 or greater filesystems available to mount”


You cannot install from a USB device with 6.2.1, but with 6.3 you can ( i beleive )
