  1. This is not a problem of wubi. The grub menu is poped out, maybe because u installed newer kernel version. Grub is always there, it just didn't show up when u just have one kernel version. If you wanna disable it, u need modify the grub2 config file, under dir /etc/grub.d

  2. If you only have Windows and a single Ubuntu install, installed via Wubi, then you should be able to eliminate the extra menu by adding GRUB_DISABLE_OS_PROBER=true to /etc/default/grub then running sudo update-grub.

    Ubuntu by default hides the GRUB menu when Ubuntu is the only OS installed, and shows it when additional OSs (like Windows) are detected so that you can choose between OSs at the GRUB boot menu. Because you are using Wubi, you can select Windows from the Windows bootloader, so you don't need to be given the option again at the GRUB menu. By using GRUB_DISABLE_OS_PROBER=true you disable the automatic detection of other OSs by grub, which both removes the Windows option in the GRUB menu and hides the menu.

    If you actually have more than two OSs, for instance one regular install of Ubuntu in addition to Windows and the Wubi install then you might not want to use GRUB_DISABLE_OS_PROBER=true. That's why I asked for boot info script output to be sure that I understand your exact situation.
