Windows 10: PC not booting to os

my pc suddenly stopped booting and went into recovery mode and when I put recovery key it didn't fix the problem. It's now booting to bios and even though my drives and ssd are fine, in boot sequence in bios it does not show it and the only option is windows boot manager. PLEASE HELP I have tried most of the methods on web.

Dual booting OS

Dave is correct, However, If you take ownership of C:\ System (Windows) when you are booted to each OS. Then depending on why you are asking this, as in you do not want others to access the other OS, then Take ownership as mentioned. Then you MUST add your
user name in the list with full permissions/control. Then you would remove all users in the list

EXCEPT KEEP THESE>>YOUR NEWLY ADDED USER NAME, SYSTEM, AUTHENTICATED USERS

REMOVE USERS>>>ADMINS, USERS & EVERYONE

Now for an OS you are booted to. You can add other users in the security users list for C:\ and/or C:\Users & C:\Users\Programs and Programs (x86) & C:\Windows

if there is others with user accounts on that OS. And then grant them the permissions you want to allow.

Because you have removed the user ADMINS, so they need to be granted permissions to access the OS as normal.

Look in Part 2 for detailed steps for ownership, permissions and sharing
