SOLVED Lost windows 10 installation after formating the other drive

[beny uliel]

Hello everyone,

I have 2 seperated (physically) SSD drives in my laptop.
Previously I had windows 8.1 on one drive, and I installed windows 7 and upgraded it to windows 10 on the other SSD drive.

I enjoyed windows 10, so I formatted the drive with the windows 8.1, but now suddenly my laptop says he can't find system drive, and I can't load the windows 10, althogh it was installed with no connection to the windows 8.1 and on another drive.

Why did this happen? how can i fix it?

Thanks,

Beny

Why did this happen?

You formatted the drive that contained your system reserved partition and your boot config files (Windows Boot Manager).

how can i fix it?

Boot from the installation media and run Start Up Repair three times rebooting between each time, booting back to the installation media

If that doesn't work you could try booting to the installation media and using the advanced troubleshooting option to get to a command prompt and type
bootrec /fixMBR hit enter
bootrec /Fixboot hit enter
bootrec /rebuildBCD hit enter
bcdedit /set {default} device partition=c: hit enter
bcdedit /set {default} osdevice partition=c: hit enter
bcdedit /set {bootmgr} device partition=c: hit enter

You may still have to set the C: partition "Active" using DiskPart (Google it)

Thanks!

It actually worked easily and perfectly (the command prompt part).

I did the first 3 steps (bootrec) and on the 3rd step it told me it found a boot program (windows 10), after that I restarted the computer and everything was back to normal.

Thank you very much!!

Definitely saved me...

Benny
