Error in Remix OS during boot after update, i.e. menu.Ist

1. Installed Remix OS 3.0 With official supported tool i.e., RemixUSBTool. On Hard Drive Partition. What Actually Happened ? 2. **After Installing** **->** **Working Normally** **->** **Download Updates** **->** **Reboot** **->** **After Installing Updates** **->** **Rebooted Again** **->** **Got Following Error** **--->** find --set-root --ignore-floppies /menu.lst error 15:File Not Found Press any key to continue . . . Here's some more information (in case needed) - Triple-booted computer with Windows 10, Ubuntu 16.10 & This One. - Ubuntu stopped working after the above error. (But I fixed this with EasyBSD). Also, after that error, the **RemixOS folder is inaccessible** from Windows 10 (and from other OSes as well.) _______________________ So, does anybody have any solution for it? (I've already tried a solution suggested on googlegroupchat, but it doesn't work for me.)
