Possible UEFI IA-32 Windows 2000 Boot

[ages2001]

Hi! It seems you added Win2000 support. Is that means Win2000 is UEFI capable boot? And can this boot.efi file usable with UEFI IA-32 bootloader (clover, etc.) for another PCs?

Completely forgot about this issue, late response but hopefully it can help someone at least. My loader will only work on the Apple TV due to its reliance on the TV's specific IDE controller (it might work on a very early Intel Mac with an IDE CD-ROM drive if the HDD is installed into the ATAPI CD-ROM port, albeit with minor modifications). There is a UEFI version of FreeLoader but it is unfinished and I haven't put much effort into trying to boot Windows with it; once it is in a better state, it absolutely will allow for booting 2000 on UEFI with my graphics driver. Clover/etc might get you to a FreeLoader error if you're lucky, haven't tried it.

Hi! I solved it by using Longhorn 5472 Bootmgr. Win2000 can boot UEFI IA-32 finally!

I highly doubt that method will work on non-CSM enabled hardware since Win2K’s stock video driver is legacy BIOS-only. In theory, the ReactOS-based method should work on any machine otherwise capable of booting Windows 2000 (some newer machines will not have working USB because of 2000’s antiquated USB drivers)

USB 3.x, ACPI, NVMe, AHCI etc. drivers exist for win2000 for modern hardwares.

And for vga, if someone manages to develop universal gop/uga driver which will work with both pure UEFI32 and legacy, it can boot properly.

ReactOS's own bootloader does not support GPT disks but longhorn 5472 one has GPT support and I managed to boot XP86 with NVMe+GPT+UEFI32.
