Cannot boot to Win 10 after installing Win 7

I installed Windows 10. I hate. I re-installed Win 7.
Now several good months have passed and I wanted to check if something was inproved in Win 10. But I cannot boot to Win 10 anymore. Win 7 boot manager simply overwrite Win 10 boot manager.



This is my bcdedit:

Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=K:
description Windows Boot Manager
locale en-US
inherit {globalsettings}
default {bootmgr}
resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}
displayorder {current}
{bootmgr}
toolsdisplayorder {memdiag}
timeout 105


Windows Boot Loader
-------------------
identifier {current}
device partition=C:
path \Windows\system32\winload.exe
description Windows 7
locale en-US
inherit {bootloadersettings}
recoverysequence {24334bf1-7a25-11e5-866b-bca012dbdc37}
recoveryenabled Yes
osdevice partition=C:
systemroot \Windows
resumeobject {24334bef-7a25-11e5-866b-bca012dbdc37}
nx OptIn


Also, in 'Start up and recovery' I see the Win 10 boot manager listed. It is actually the default boot manager. But it will still load Win 7 by default and without showing any menu during Win startup:
