BootMGR not found...
Hey! You're facing a common issue when trying to boot Windows XP on an older system like Pentium 4. The BootMGR error usually means the bootloader isn't set up correctly. Since you mentioned using ISO files, you might want to try creating a bootable USB drive with Windows XP and then boot from it instead of using the installation media. Let me know if you need help with that!
You can't start a boot from an ISO, it must first be written onto a CD or USB that's ready to boot. Rufus is a top choice for creating such a bootable drive. https://www.techrepublic.com/article/pro...st-any-os/ After that, adjust your BIOS settings so the USB becomes the first boot option before the main hard drive.
