That means the image was not created in a partition with unallocated space at the end of the drive.
You did not mention your MB, or type of HDD, but there are a bunch of senarios where it won't work, as listed on the express recovery2 applet instructions.
Here are some:
USB hard disks are currently not supported.
Does not support RAID/AHCI (class code 0104/0106) hard disks.
Capable of backing up and restoring only the first physical hard disk.
Hard disks detection sequence is as follows:
a.PATA IDE primary channel
b.PATA IDE secondary channel
c.SATA IDE channel 1
d.SATA IDE channel 2
e.SATA IDE channel 3
f.SATA IDE channel 4
Xpress Recovery2 supports only PATA hard disks and not SATA hard disks on the following motherboards:
GA-K8NF-9 (PCB Ver. 1.0)
GA-K8NE (PCB Ver. 1.0)
After reading the instruction manual, if you don't fall into any of these exceptions, remove the applet, and reinstall, and try again
What does "Remove the Applet" mean?
#1 he must have a Gigabyte board because that is a Gigabyte utility,
#2 That program doesn't show up in "Add/Remove" programs in control panel.
I have read a multitude of people asking that question "How to remove?"
Have not seen any answers yet.
I'm not sure but, try restoring your computer to a time before you installed Xpress RC2.
If your answer has any credence, and the code 100 means what you say,(and that's not in the manual)
Then see if you can reclaim the Unallocated disk space by expanding your "C' partition.
If that works, (I will try that later) Then go into the BIOS and disable the Splash screen.
Because only by hitting F9 at boot will you enter XR2.
If none of that works I would try a format of "C" and reinstall Windows.
That will be my next choice and I will use Acronis Home 2012 and boot from the Acronis disk. Format --remove disk and install Windows,
There is always more than one way to kill a pest.
