Thanks for your reply. I will outline the steps I've taken thus far.
Using Easus, I cloned my old C drive to a new empty WD 1TB Caviar Green HDD. Result was an E drive with 2 volumes (9.76 GB "restore" volume, and E (OS) volume, with some remaining unallocated space. I then tried the following 3 scenarios (none of which worked):
1) I left the old C in place, but using F10 on boot-up, I selected the new E cloned drive as my boot device. The PC booted normally, but I couldn't tell for sure which drive it was actually booting from, the old C or the new E.
2) I rebooted, and did the same as above, but deliberately selected the CD/DVD drive as boot device, and as expected, did not work. So far so good maybe.
3) I rebooted, but this time used F2 to enter Bios settings, and changed the boot order there: New E drive, followed by CD/DVD drive. F10 to exit and save. The PC failed to boot from the E drive, and instead tried doing so from the CD/DVD drive, which, as expected, failed again.
Next I physically removed the old C drive, and moved the new E into position 0 on the motherboard. I entered Bios settings again to make sure that the new E was the initial boot device. F10 to save and exit, and the boot continued.
But it seems to have not recognized the new E as a bootable device, and instead proceeded to the CD/DVD drive, and failed.
I went back and set up my PC back to its original config... and all worked as if the E drive were not there. With nothing to lose, I decided to do two things to the new E drive: I expanded the E (OS) volume to use the unallocated space on that drive, and also removed the 9.75 GB volume, as it appeared to be nothing but a restore (back to Vista) safe utility. I also tried expanding the E (OS) to use the now unallocated 9.75 GB, but stopped when it warned that the drive would go from Basic to Dynamic.
I went through all 3 of the scenarios as above, with same results.
The attached image show Disk Management screen capture (which I hope is visible to you... I've never done this before) as my PC stands now.
So, I am at a loss as to what to try next. I don't know how to change the Master Slave on the two Drives, but I thought that physically removing the C drive, that the E drive, now first in line for booting, would in essence do the same thing.
I hope I've managed to answer your questions, and that what I've provided is useful. Thanks very much for your help.
