Computer was set up with C drive with D as the partition for Windows files. I sometimes used a Toshiba external drive with a USB connection that was listed as the F Drive . It's not currently connected. I am a total novice so taking this one step at a time it's good. Worried I might make things worse if possible. Thanks

Let's repair the MBR and see if that makes a difference. Please refer to the video that Compton shared in his post. You will need to enter the command as follows
bootrec.exe /fixmbr
Please also try the steps as outlined at https://www.technipages.com/windows-10-fix-unmountable-boot-volume-error

Do I need to back up the files before I run the fixmbr.

bootrec fixboot

I entered the command "bootrec / fixmbr" . And error came back that read "Data error (cyclic redundancy check). I am using the windows 10 fall creator disk. I hate running chkdsk since I do not have my data backed up. I can try running the steps for exporting the files to back up the registry outlined under Vista video. I assume my windows files are on the D partician. My unease is that I do not understand exactly what the commands are doing so will this apply to windows 10 files and i can't see what files are on D drive.

well a chkdsk will need to be run to fix that error
you should not lose any data by running chkdsk

I will run chkdsk. Thank you. I did try "bcdedit /export D:bcd_backup" the error msg was "The store export operation has failed. The system cannot find the file specified." I also use this for Drive C. Same error message. I also tried looking for filename "regbac" and received the same error message.
Do I need to run chkdsk on D since that is where I believe windows files or both this D &C drives?

Just to let you know, the chkdsk process may appear to be stuck at a certain per cent and that is normal; please let it complete
