Hikari Calyx Tech UEFI Migration Guide

UEFI Migration Guide

Starting from Hikari PE V9.0, Legacy mode support will be dropped, as we believe x86 PC without 64-bit UEFI (Unified Extensible Firmware Interface) support will have a painful time of running Windows 11.

In this article you’ll learn how to migrate to 64-bit UEFI mode for different brand of PCs. You can click PC brand name and see the procedure.

Should I disable Secure Boot?

Hikari PE Project supports Secure Boot, so you don’t need to disable it. However if you plan to boot into Hikari PE via Ventoy, you should disable Secure Boot. Secure Boot is not mandatory for using Hikari PE Project.

What can I benefit from switching to UEFI mode?

  • The boot procedure will be smoother and faster than using Legacy mode. All oldschool self-check procedures will be skipped.
  • You can install and boot OS on a disk driver larger than 2TB.
  • UEFI mode is required for most of PCIe SSDs (e.g. M.2 NVMe SSD), as they usually lack BootROM to use under Legacy mode.
  • With Secure Boot enabled, it will help you defend your PC from being infected by most of boot sector viruses effectively. Obviously virus developers cannot buy Secure Boot Certificate from Microsoft to sign their viruses.

What if I want to use Hikari PE on an older hardware without 64-bit UEFI or a 32-bit PC?

For PCs with 64-bit x86 CPU, Please use Hikari PE V8.x or older versions.

For PCs with 32-bit x86 CPU and PAE, NX, SSE2 instruction sets, please use Hikari PE V4.x.

ARM64 version of Hikari PE Project isn’t ready.

I am using 64-bit Windows 10 under Legacy mode and the PC doesn’t boot anymore after transiting to UEFI mode. Should I wipe out entire disk and reinstall OS?

No you needn’t. DiskGenius included in Hikari PE Project can convert an existing MBR partition table layout disk drive into GPT (GUID Partition Table), then you can create EFI system partition and Microsoft Reserved partition at the end of your hard disk drive. After that, use Dism++ to fix boot files.

Once conversion completes, all your data will remain safe and you can benefit from advantages of using UEFI.
