Ghost 15 shows all drives "unavailable" after adding a Linux partition to my Windows 7 laptop

I run Ghost 15 (updated with Liveupdate) on a laptop running Windows 7 Home Premium SP1.

My 500GB hard drive was originally divided into three partitions:

                 Windows and applications on C:\

                 Data on D:\

                 Backups on E:\

 

Ghost ran satisfactorily for a year.  Status sometimes showed the E:\ drive as unavailable but it still wrote backup files to a folder on this drive.

 

I recently created an additional partition on which I installed Ubuntu Linux,using a dual-boot configuration.

Everything continues to operate normally within Windows 7 with the exception of Ghost which now shows all my drives as "unavailable". 

 

I ran "Partinf0.exe" from the Ghost utilities directory.  The attached test file was generated.  It has a line which reads:

"WARNING: Logical partition entries are not in sequential order."

 

I assume that this refers to the fact that the Linux partition is physically located between the C:\ and D:\ partitions.

 

Can anyone suggest a solution?
