Windows 10 legacy mode setup problem

[nguyen ha thai trong]

In the immediate future, you should defragment the iso file as recommended by Steve2926, because as you describe, installing your windows iso in legacy mode when loading the iso from ventoy mode often succeeds.
As I stated the workaround earlier, you can either download the standard windows iso from Microsoft and replace install.wim/install.esd of the Microsoft iso with your install.esd or replace your boot.wim with boot. wim from Microsoft, should solve the problem.
Note : Need to back up a copy of your windows iso before doing so.
