Hello,
So your computer was booted in BIOS/legacy mode before Debian installation.
Furthermore, the Calamares installer is used by the Debian Live ISO, so you are not running the official Debian ISO installer, which can be downloaded here:
The message quoted above is from the Calamares installer:It is shown when the installer detects that it is running in a computer booted in BIOS/legacy mode (not booted in EFI mode).“Option to use GPT on BIOS
A GPT partition table is the best option for all systems. This installer supports such a setup for BIOS systems too.
To configure a GPT partition table on BIOS, (if not done so already) go back and set the partition table to GPT, next create a 8 MB unformatted partition with the bios-grub flag enabled.
An unformatted 8 MB partition is necessary to start Debian on a BIOS system with GPT.”
