After the installation, the system did not boot and displayed the message <code>Error 1962: No operating system found<\/code>. This is the solution I found after my third attempt.<\/p>\n\n\n\n<p>First, ensure that UEFI is enabled in the BIOS before starting the installation. The Debian installer shows whether the system is booted with UEFI. Look out for the message on the Welcome screen.<\/p>\n\n\n\n<p>Second, create an EFI System Partition (ESP) when configuring the disk. This will contain the EFI firmware that allows Debian to boot in UEFI mode. If UEFI is unavailable, you will <strong>not<\/strong> see this option.<\/p>\n\n\n\n<p>Third, proceed with installation until it completes. Reboot when prompted <strong>but expect to see <em>error 1962<\/em><\/strong><em>.<\/em> You need a few more steps to fix it.<\/p>\n\n\n\n<p>Fourth, boot into the Debian installer again and choose <em>Rescue<\/em> mode. Mount the <code>\/root<\/code>, <code>\/boot<\/code>, and <code>\/boot\/efi<\/code> partitions when asked. Then, open a console into <code>\/root<\/code> from the Debian installer menu.<\/p>\n\n\n\n<p>Fifth, copy <code>\/boot\/efi\/EFI\/debian\/grubx64.efi<\/code> to <code>\/boot\/efi\/EFI\/boot\/bootx64.efi<\/code>. <a href=\"https:\/\/wiki.debian.org\/UEFI#Force_grub-efi_installation_to_the_removable_media_path\">The reason for doing this is documented.<\/a> <strong>This is a crucial step.<\/strong><\/p>\n\n\n\n<p>Lastly, go into the BIOS setup, enable UEFI and disable CSM to force UEFI boot mode only.
