Judging from the prompt displayed on the picture (although it is very paste), it is because Ghost did not complete the ending, which led to the failure to activate the C partition, so there was no bootable device and no other bootable device at startup, and this prompt appeared.

The solution is simple:

2. 1 whatever can be booted into WINPE, whether it is a CD or a USB flash drive. You can enter the BIOS and set the CD or USB flash drive as the first startup item, or after inserting the CD or USB flash drive, you will be prompted to press the ESC key in the figure when restarting, and select the CD or USB flash drive to start from one of them.

2.2 Boot into WINPE and then run Ghost to back up the system from the hard disk, that is. Gho file again. Be careful not to close it again until you are prompted to restart and choose it to restart.
