Failure to prompt reboot

Thread needs solution

I apologize if this is the wrong place to put this post--but I've been wrestling with this problem for a couple of days and I think I have narrowed down potential solutions.

I am attempting to use Acronis True Image to clone my HDD onto a new SSD. The first time I attempted this process, the wizard attempted to ask for permission to reboot the system. I, alas, the human error, accidentally denied this rather than allowing it, and subsequent attempts at this process have so far never asked for permission to reboot, and thus produce one of two results, seemingly at random:

The disk is cloned "properly" as a boot drive, but partitions seem to be invalid and portions of Windows fail to function or load properly even though Windows itself launches (dlls are missing or corrupt, portions of the control panel simply crash--Windows "works" but is unusably unstable);

or, more commonly, the drive simply fails to become a boot drive and Windows will not launch at all.

Despite the fact that I have reformatted the drive several times and repeatedly run the cloning wizard, I have never since been offered an opportunity to properly reboot so boot partitions can be properly built. Is this a known error, and, if it is, is there a way I can fix it?

Trevor, welcome to these public User Forums.

Quick initial question: what type of PC are you working with here?  Desktop / Tower PC or a Laptop / Notebook one?

Next, did you make a full disk backup of the working HDD before attempting the clone operation?  This has always been strongly recommended as provides a safety net for if issues such as this arise!

The first suggestion is to check that you are actually doing a full Windows restart when trying to clear this issue?  If you have Windows Fast Startup enabled then just doing a restart will use that option and not actually do a full shutdown and restart to clear any pending operations.

You can force a full shutdown by pressing & holding a Shift key when clicking on Shutdown, then restart Windows after that.

Personally, I very rarely use cloning because of the various complications that it can bring.  I use Backup & Recovery, with the latter using Acronis bootable rescue media so that Windows is not involved in the process at all.  If you have a laptop and are replacing the boot drive, then this is the recommended method to avoid other bootability issues.

Please see KB 56634: Acronis True Image: how to clone a disk - and review the step by step guide given there.

Note: the first section of the above KB document directs laptop users to KB 2931: How to clone a laptop hard drive - and has the following paragraph:

It is recommended to put the new drive in the laptop first, and connect the old drive via USB. Otherwise you will may not be able to boot from the new cloned drive, as Acronis True Image will apply a bootability fix to the new disk and adjust the boot settings of the target drive to boot from USB. If the new disk is inside the laptop, the boot settings will be automatically adjusted to boot from internal disk. As such, hard disk bays cannot be used for target disks. For example, if you have a target hard disk (i.e. the new disk to which you clone, and from which you intend to boot the machine) in a bay, and not physically inside the laptop, the target hard disk will be unbootable after the cloning.
