I have installed windows 10 on second drive before (sda2 - second drive has two partions) After that i have installed ubuntu 18.04 on first disk (ssd drive). But now only boot to ubuntu, cannot go to windows. Even windows not show on grub menu.

You need to change the boot order to first drive in F11 menu, otherwise it hits drive 2 which only has grub entry for Ubuntu.

EDIT: it might be F12, whichever settings menu where you configure the boot order, not the one to pick for a single boot.

  • now 1st boot order is ssd driver (which ubuntu was be installed)

  • you have to set the first boot to the driver with Windows 10 on it, sorry for the confusion!
