It won’t cause any damage. Legacy mode (a.k.a. BIOS mode, CSM boot) matters only when the operating system boots. Once it boots, it doesn’t matter anymore. If everything works as expected and you’re happy with it, legacy mode is fine.

Is UEFI the same as BIOS?

UEFI stands for Unified Extensible Firmware Interface. It does the same job as a BIOS, but with one basic difference: it stores all data about initialization and startup in an . efi file, instead of storing it on the firmware.

Why is UEFI better than BIOS?

UEFI has a detailed setting menu, more useful than traditional BIOS. UEFI supports secure boot, preventing PC from being damaged by malware. UEFI runs in 32-bit or 64-bit mode, and the addressable address space is increased based upon BIOS, the boot process is much faster.
