bootdisk problem

[relborg]

hi there i am writing a beginner program to ghost an image of my one hard drive to an image file on the other hard drive. i have mannually gone through the steps and it seems like only the a: drive is available when you select the destination. is it maybe that i need to have a certain boot disk to boot into dos? when i come out of ghost i cannot change to any other drive letter .
pls hlp:)
