I have a two disk set up, both disks are on the same IDE controller, primary and secondary. Both have seperate Windows intsallations and I chose which one to boot from the system BIOS which provieds a boot menu. This has worked fine for quite a while. My secondary disk is running out of space so I connected a new bigger disk instead of the current primary. I then booted the old secondary and cloned it to the new primary. Now when I install that new disk as a secondary in place of the old disk it will not boot. When I select the new secondary from the BIOS boot menu I get messages to say that Windows could not find various file, e.g. ntkrnl, ntfs.sys etc. If I remove the primary disk so that the new secondary is the only disk it boots fine. I'm using Cable Select to define Master/Secondary. If I re-install my old secndary in the same two disk configuration it boots fine. If True Image "clones" the disk, how come the original boots but the copy doesn't?
