Hi,
 
My current configuration was:
Primary drive with windows on it was an ssd with drive letter C.
My second hard drive have two partition on it, E and F.
 
When I upgraded to windows 10, for unknow reason my boot sector go to the hdd drive, not sure if E or F but windows still on the C drive.
My HDD drive stop working correctly and didt boot always creating error about boot device.
 
I want to put the boot device on the SSD drive for be able to replace the broker HDD.
 
 
Now, the real tricky part... be prepare...

My computer is a laptop and the screen are broken.
I must connect a tv on it using his HDMI conector.
Unfortuntly it's recognize tv only when windows boot up.
 
So my only solution is to take these drive, putting them in another computer and find a way to solve this using another computer.
 
Any command that I found in this forum seem risky to me as I'm not on the computer with trouble.
 
How can I creating a boot sector on a drive that will be use on another computer... Basic method will just broke the computer I use to repair the other one.
As I did't have screen on the laptop, I can't use any recovery console.
I hope you got an idea because I feel like in a dead end.
 
Thanks

Attach the ssd to another computer and disconnect any other drives that are connected before doing the next step.

then boot up that computer with a windows installation disk.

You need to go to the recovery console (command prompt)

 

Then type in the following commands:

 

Type DiskPart followed by ENTER.

Type List Disk followed by ENTER.

Type Select Disk X (where X is the number of the disk you want to boot from, probably 0) followed by ENTER.

Type List Partition followed by ENTER.

Type Select Partition Y (where Y is your partition you want to boot from) followed by ENTER.

Type Active followed by ENTER.

 

Type Exit followed by ENTER.

 

Type Bootrec /fixmbr followed by ENTER.

 

Type Bootrec /fixboot followed by ENTER.

 

Type Bootrec /rebuildbcd followed by ENTER.

 

Shutdown the computer.

 

Put the ssd back into the original computer and it should work now.

Oh, I did not realize we were talking about a GPT formatted disk. Sorry, I don't have the experience in GPT/ UEFI booting to help you with this.

 

Anyone else?

Maybe try this:

 

(Attach the ssd to another computer and disconnect any other drives that are connected before doing the next step.)

 

Then follow the instructions in the link below.

(be aware that you might not have all the required partitions so you might need to create any that are missing)
