When attempting to install Windows on a newly connected SATA drive, users may encounter issues where the installation does not detect the drive, despite it being recognized in the BIOS. This can be due to the need for specific SATA drivers that must be provided during installation by pressing F6. Some users have successfully installed Linux on the same drive, indicating that the hardware is functioning correctly. To resolve the Windows installation issue, it is recommended to disconnect all other drives, set the SATA drive to IDE mode in the BIOS, and then attempt the installation. After successfully installing Windows, users can switch the SATA mode to RAID and reconnect additional drives. If problems persist, reverting to IDE mode may help in loading the bootloader (GRUB) correctly. It's noted that certain motherboards may not support dual RAID-IDE modes, and users might need to locate a floppy drive to load necessary drivers during the Windows installation process.
