Lenovo Workstation SSD Upgrade: Error 1962 No OS Found

[Schada]

Hey everyone,

 

I'm working on upgrading a Lenovo workstation from a HDD to a SSD.  I used Macrium Reflect as a free software to copy everything from my HDD to my SSD.  It worked great that day of and a few days afterwards (shutdown after each night).  But now every time I boot the PC I get Error 1962 where it can't find the OS on the SSD.  Looks like next steps are to use Win10 Media Creation in a USB to repair the startup but I can't figure out why this would be happening now?  Even after a few days of shutdowns it can't find the OS anymore.  I haven't changed anything else mechanically or software-wise since I switched to the SSD.  Just regular daily use.  Anyone know why this is happening now?

 

Thanks,

Adam

All you can do at this point is boot from the installer media and repair. I've had PCs have problems with cloned drives in the past.

It's a cloned OS so really it could be anything, I would use a Windows installer USB and run startup repair as @Mel0nMan suggested, if that doesn't work and if you have Macrium Reflect make a portable version if you don't have one already and boot into it, it should have a Boot Fix option and that can sometimes fix those issues as well. A boot fix is usually necessary after every clone depending on how you do it. If you can't get it to work and still have the original drive try doing a raw copy(sector by sector) and see if that works. Sometimes clones just have issues. It can also be a problem if the HDD you are cloning from is having issues.

If you only did the migration a few days (and you don't have any work you'd lose), just copy the HDD to your SSD again, thus resetting whatever went wrong. Unless you already wiped your HDD?

 

Edit: I didn't read @SpookyCitrus whole post that also says to do this. So yeah...
