Supported phones for Windows 10 Mobile Insider Preview


Your list confirms my phone is eligible, Lumia 521. The windows Insider App fails after ~ 15 seconds, restores data and gives me error 80073cf9. I trouble shot this and went thru all the steps mentioned on several websites including MS without any luck. Short of a hard reset, this is where I am now. Suggestions appreciated.

 

Reinstall windows 10 without losing data

my laptop currently windows 10 won't boot into desktop or in login screen after I did some force shutdown by holding down power button.

What to do?

These are the steps I performed

1. Bootrec /fixmbr

2. Bootrec /fixboot

3. Bootrec /rebuildbcd

4. Chkdsk c: /f /r /x

in step 4, I've got an error in step 2 then i close the cmd in advanced boot options.

now my question is, what other method should I need to do without losing my very important data inside my drive?

is system repairing using a bootable disk can be use? withput losing data?
