Help! Can’t Boot from My New SSD After Cloning

You mentioned using Macrium Reflect to clone your drive. Could you clarify which partitions you cloned and their sizes? Sometimes certain partitions need to be specifically selected or handled differently for a successful boot.

If you're getting bluescreens, try grabbing the crash dump files to get a detailed look at what’s causing it. Boot into Windows or Safe Mode if you can, and check the Minidump folder for crash logs. You can zip those up and share them for more precise help.

It’s generally a bad idea to have two identical drives attached when booting. It sounds like the easiest fix is to fully remove the old SSD and try booting again from the 1TB SSD. Once you’ve confirmed it works, you can reformat the old drive and use it for additional storage or backups. Just be cautious with cloning, as it can sometimes create signature collisions if both drives are connected. Macrium Reflect usually handles that well, but it’s worth checking.

Your cloning might’ve had issues. I’d suggest getting a different cloning program or double-check that all partitions were cloned properly. Sometimes, if the clone wasn’t accurate, it results in a boot failure.

I’ve had similar boot issues in the past. Make sure you’re using reliable cloning software. Macrium Reflect is good, but not all cloning software works the same. It's usually best to do a bit-by-bit copy to ensure everything is transferred correctly.
