I am trying to install Debian 10.2 XFCE DVD with non-free firmware. It says on the monitor everything has completed successfully. Now remove the removable media from which is the USB stick and boot into your new system.
But the computer doesn't boot into newly installed Debian Buster. I have installed Grub in the MBR (Master Boot Record of Seagate's USB expansion drive). The Lenovo laptop is setup with the setup UEFI as UEFI and BIOS both, with BIOS first. Can anybody kindly tell me what I am doing wrong? Can anybody kindly point out where am I making the mistake? Shouldn't the computer load the MBR's Grub as I have pointed the boot order (first by pressing continuously F2 and changing Boot Priority and then Boot Option by pressing F12) to the Seagate USB expansion drive? Let me know if you need any information or setting info about installed Debian Buster's configuration. Thank you. P.S. For your information I previously installed Debian Squeezy's GRUB on to the same Seagate's MBR. But now I deleted all the partitions and used the guided automatic partitioning scheme that came with Buster and have a fresh install. I have turned off Secure Boot.
