Thread needs solution

Source HDD is Windows 7 MBR. I removed the drive and backed up on a Windows 10 UEFI PC using a dock. When I restore to a new SSD using the same dock, I cant get it to boot on the legacy system. I did restore MBR from backup. I get a 00000e9 Stop error. Any ideas? Maybe a bootloader problem?

Thanks for the reply. My situation is a little different. I want to recover and restore a BIOS based system ON a UEFI based system using an external HDD dock. I was communicating on reddit with someone from Acronis on this topic. Again, it's a BIOS based system I want to restore but I backed up using a UEFI based system with the hard drive connected to a USB dock. I am going to try and backup the source on the BIOS system to see if it will make a difference. Thanks

I sugest you clone the old HDD directly to the new SSD.... and pray :)
