Cloned disk sector-by-sector, got "a required device isn't connected or can't be accessed"

clone77

I have an SSD (Legacy boot I think) with dual Ubuntu and Windows 7. I want to clone the disk exactly.

I did the cloning on a second machine, connecting both drives via SATA-USD cable. The cloning disk is identical make and size to the original 

I did:

"All tools"
"Disk Clone Wizard"
"Sector by sector"
Chose Source and Dest
Apply

AOMEI reported the clone was successful.

I plugged the cloned disk in to the machine which previously had the original disk (i.e. same hardware), Grub came up and all OSes were detected. Everything seemed fine. However, after I selected Windows 7, I then got:

"a required device isn't connected or can't be accessed"

Given the hardware was identical and the disk should be identical, I am not sure what is wrong.

I think I got the same problem 6 months ago when I tried this.

@Clone77, Sorry that our software currently can't clone Grub boot.
And, generally, for system disk, we suggest that you connect it to the original computer to boot and do the clone.

This error could be caused by a slightly different Partition Table MBR/GPT, in the destination disk, than what the OS was expecting.

For Disk Clone method with exact / sector-by-sector setting, I recommend using Partition Assistant, because only it will copy the Partition Table MBR/GPT; Backupper does not copy that, even with sector setting.
