I have a PC with Windows 10 installed on the only 1 TB hard drive that I have been using for a year or so. The hard drive was only 35% used. I installed Debian 8.7 from an ISO on a USB drive. During the installation, the installer displayed a list of current partitions and free space on the drive, including a 933GB NTFS partition. I used the Debian installer itself to shrink this partition to 50% and installed Debian on the new partition created. Even so, further on during installation, the installer did not recognize any other OS installed and said that, if there IS one and I continue installation, it may become un-bootable but I would be able to fix that manually by editing some file. So I continued with the installation and it completed successfully. However, when I boot up the machine, I do not get a choice of booting to Linux, and it directly boots to Windows 10. A couple of points:
Windows Boot Managerjust boots into Windows 10.
From Windows command line, running the command
bcdedit /enumshows only Windows boot loaders. (Screenshot) How can I get my machine to boot into Debian Linux OS? Thanks a lot for your help. I have spent way too much time booting and re-booting :-)
EDIT: Just wanted to add that I did select
Yes to install grub-loader in the master boot record of the first hard drive.
