Setting up Windows 10 via UEFI assistance
You're facing a common setup issue when switching to Windows 10 on a new SSD. The warning about partition order usually relates to how the operating system recognizes your drives. Since you have GPT partitions, ensure they are listed in the correct sequence during installation. Double-check that the recovery partition is present and properly formatted. Also, confirm that the EFI system partition is correctly sized (100MB) and that the OS is installed on the intended drive—avoid legacy modes if possible. If unsure, run a GPT partition check tool before proceeding.
Disconnect the additional hard drive and adjust the SATA configuration in the BIOS to AHCI rather than Compatibility or Legacy. Ensure AHCI mode is selected for the SSD drive during installation. Once installed, you may reconnect the other drive, making sure the BIOS is configured to boot from the SSD at that stage.
When encountering a BSOD during the transition from IDE to AHCI, open Windows, press R, type msconfig, and reboot into Safe Mode. Enter the BIOS by pressing any key, switch to AHCI settings, save the changes, and you'll be in Windows Safe Mode. Restart and return to normal booting. This method worked for switching to AHCI with my SSD.
