Solved! Recovery Problem Vaio

Nov 3, 2018
Hii all
I installed Win 10 in my Vaio and it was on Win 7 when we purchased. After installing Win 10 now the recovery drive is showing 0 Byte and I want to recover it to old Win 7 which was actual win of laptop when we purchased. Please help.
Can you post a screencap of the Disk Management window?

Sounds like that partition got deleted during the Win 10 upgrade install.
