I tried to reboot in safe mode multiple times but I got the same results. I have 1 hard drive(1TB) and I have tried unplugging and plugging it back in again to no avail. So I made a windows 10 bootable USB to try and run system repairs, upon getting to the startup screen I attempted the following Troubleshooting options:

I then ran Chkdsk /r which also showed that there wasn't any problems and no further action was needed. I then tried the following commands as recommended on other posts:
I'm assuming the OS is corrupted or not being detected but I don't know what else to do now, any help?
thanks in advance.

- Bootrec /fixboot - Operation completed successfully
- Bootrec /scanos - Identified 1 windows installation and completed successfully
- Bootrec /rebuildbcd - identifies window installation but upon entering 'y' it says the requested device cannot be found.
