JUNOS 10.1 Software Release Notes
Installing JUNOS Release 9.6 or Earlier Release on Systems with Dual-Root
Partitioning
JUNOS Release 9.6 and earlier is not compatible with the dual-root partitioning
scheme. These releases can only be installed if the media is reformatted with
single-root partitioning. Any attempt to install JUNOS Release 9.6 or earlier on a
device with dual-root partitioning without reformatting the media will fail with an
error. You must install the JUNOS Release 9.6 or earlier image from the boot loader
using a TFTP server or USB storage device.
NOTE: You cannot install a JUNOS Release 9.6 or earlier package on a system with
dual-root partitioning using the JUNOS CLI or J-Web. An error will be returned if this
is attempted.
NOTE: You do not need to reinstall the earlier version of the boot loader.

Install the image using the following command at the loader prompt:

For example:

media with single-root partitioning.
