Emulators that mimic standard BIOS video calls (INT 10h) required by the Windows XP bootloader.
Pure UEFI systems expect GPT partitioning, but Windows XP (32-bit) requires an MBR structure to install. The custom UEFI bootloader wrapper resolves this by utilizing a or allowing a raw MBR partition layout that the UEFI can still read via the FAT32 wrapper file system.

This is the final trick. You must use a tool like (running from a Windows 10/11 PE environment or another partition) to create a BCD store that can chain-load the XP NTLDR. Alternatively, the rEFInd boot manager installed on a separate small FAT32 partition can detect the MBR partition and "chainload" it, acting as a translator between your UEFI hardware and the legacy XP code.

Proceed with the GUI setup phase. If the screen goes blank during the transition to the GUI phase, your UEFI video emulation driver is failing to map the frame buffer. You may need to retry using a different video patch resolution. Post-Installation Hurdles: Drivers
