Final answer:
To install Windows on a GPT disk, UEFI compatibility is required. GPT is linked with UEFI, which supports larger drives and versatile boot configurations, unlike the older BIOS firmware which does not support GPT.
Step-by-step explanation:
The condition required when planning to install Windows on a GPT disk is c. UEFI compatibility. GPT stands for GUID Partition Table and is a standard for the layout of the partition table on a physical hard disk. It is associated with UEFI (Unified Extensible Firmware Interface) which is a modern version of firmware that is capable of working with larger drives and allows for more robust and versatile booting configurations as compared to the older BIOS firmware interface.
When you install Windows on a GPT disk, you need to ensure that the system firmware is UEFI, because older BIOS-based systems do not support booting from a GPT disk. MBR (Master Boot Record) partitioning, the FAT32 file system, or BIOS compatibility are not relevant conditions for installing Windows on a GPT disk.
