This kind of problem is very common as I see, but I can't find anything helpful anywhere.

There was a common hdd with an old Win7 installation. A new SDD was bought, a new fresh Win7 was installed on it, dualboot with the old hdd system.

Now, I could see that the new SDD OS needs the Bootloader on the old HDD, but never thought it would actually not work without the HDD.

The HDD broke, now the SDD OS doesn't boot. "BOOTMGR is missing"

I tried loading from a bootable usb flash with command prompt, the sdd is visible, the rebuild of the bootrec /rebuildbcd was successful.

Still the SDD OS doesnt load, it says "no OS found".

I'm out of ideas, can anyone please help me?

Do anyone of these solutions help:… – Ramhound Oct 2 '13 at 14:15
I just solved the problem by simply auto-repairing the Windows 7 OS on SDD with the bootable USB flash drive. – ScepticalAstronaut Oct 2 '13 at 14:22
Just for the recorcd: The SSD actually work worked fine. It missed some software, but saying that it does not work is like saying "My paper notebook does not work because I have not yet written my notes on it". – Hennes Oct 2 '13 at 14:33

Actually all your system files are safe in your SSD.But you are missing a small piece of software , bootloader, which is a computer program that loads the main operating system or runtime environment for the computer after completion of the self-tests.

you can rewrite the bootloader to your MBR(in SSD) using the following methods.

1)Try Using the Automated Startup Repair from the Windows Install Disc.

2) else you can get to the Command Prompt.enter image description here


bootsect /nt60 all.
