Cant find System Image on Passport drive while replacing my PC hard drive

PC is Using Windows 7.  Internal drive is failing. I created backup & system image to MyPassport drive.  Also created recovery disk. (DVD).

Started PC from recovery disk and when I get to the window to enter the location of my system image, it can’t find the Windows Image Backup.  The Passport drive is availble but only 30mb is available.  The Passport drive is 1.5TB.

What do I do to access the remaining space on the external Passport drive?

Hello and welcome to the community.

How did you created the system image and the backup? Normally when you boot from the recovery disk you can select an image to restore from.
