Any suggestions for this error? It comes intervened from another workshop.

the machine turns on normally, but halfway through when the apple comes out, spots appear on the color screen, take the image externally to a monitor and it's the same problem.

When moving the cursors and opening windows it generates that problem.

Check the image booting Windows, before loading graphics driver.

Sorry

Check the image booting Windows, before loading graphics driver.

if you are referring to the system, I already did it with an external disk with system, booted

Do you get same weird image booting Windows?
It will use generic graphics driver.
If image is good, then find and load proper driver.
If goes bad, then iGPU problems...
