Windows XP x64: EFI_NOT_FOUND

[2W10]

Hi,

I am trying to boot Windows XP x64 using Quibble, but I get the error EFI_NOT_FOUND. How can I fix this?

For XP you'll need to find a version of the UEFI firmware with CSM support included.

Ok. I am using VMWare. Should I use another hypervisor. Also I am thinking of using this to install XP on UEFI-only Surface Pro 1, would this work? If so, would it be possible for CSM to not be required in the future?

Support for the UEFI-only boot (no CSM) was added in x64 Windows Vista / Server 2008 SP1 (NT 6.0.6001), x64 Windows XP / Server 2003 (NT 5.2) doesn't support it.

@yurikoles - I don't think that's right. IIRC it's Windows 8 that's the first not to need the CSM.

@2W10 - this could be done by reimplementing the relevant BIOS interrupts, but it's not something I'm planning to do at the moment. It'd be quite a big job, and its only use would be allowing very old software to run on very new hardware. Sorry.

That is correct. Booting Windows 7 on an UEFI system without a CSM is an awful hack (mostly involving VGA.sys) that may or may not work.

Ok I understand. Could it possibly be done in the far future?

Something like https://github.com/CloverHackyColor/CloverBootloader is probably closer to what you are looking for. Clover is usually used to provide uEFI support on BIOS systems, but from a quick skim of the readme, it sounds like the reverse may be possible.

Where does it say that? It doesn't sound like that to me.

I've added it to the to-do list in the README. It looks like the Steam Deck is another machine which comes without a CSM, so it'd be nice to be able to use Windows 7 etc. on that.

Yes. It is possible to do something like that. FlashBootPro EFI files emulate the BIOS environment, which is what allowed Vista and 7 to boot on the Surface Pro 1.
