screen garble problem when enter windows install

[jjyoo0308]

First of all, please understand that the grammar is not natural as we used a translator.  I was experiencing a dhcp problem, but I solved the problem through Googling, and now I am suffering from a screen garble problem. I've tried every possible resolution, but nothing works. Of course, there is no problem when booting the iso file from USB. Looking at past threads on the forum, I see several people complaining about this issue. Why hasn't the bug been resolved yet?
