Can't access Windows Vista - boot menu

[parvind]

Hello,
  I have windows vista and in a rush I installed Linux Lite while running ISO from CD and created partition following the instructions.

Now, I don't know how to access Windows Vista as I did not do backup. I chose "add this OS in addition to existing" while installing. So for sure, Vista is not deleted.

I installed Grub Customizer and customized to see other operating system, but I don't see Windows Vista in the list. Any help is sincerely appreciated.

Thanks,
Arvind
