Remix OS OTA Update failed causing Windows 7 system volume on disk corrupt

[www.jas...@gmail.com]

Hi. Yesterday i update my remix os via OTA, and after reboot it said Error: Cannot find GRLDR in all devices. Press ctrl+alt+del to restart. And after restarting, the Windows 7 in my computer also failed to boot with error code STOP:0x00000024. When perform system repair, i discover that the remix os had spilt my C Drive into 3 seperate drive, which are C: , F: and Boot(X: ). I found that the windows was transfered into F Drive, but the partition size in it is 0MB. When i peform the startup repair, it said that the system volume in disk is corrupt. Do anyone know how to fix this problem? Thank You.
