Windows won't boot after installing Ubuntu from a usb stick. I tried updating grub:

$ sudo update-grub
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-4.15.0-20-generic
Found initrd image: /boot/initrd.img-4.15.0-20-generic
Found Windows Boot Manager on /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi
Adding boot menu entry for EFI firmware configuration
done

It did't help.I checked my partitions and there is a microsoft reserved partition at /dev/sda3 and flags msftres.

I also tried updating grub from startup up window from advanced options under ubuntu header.

While installing i made three separate partitions, and before anything I had my window partition shrunk, as was required.

Does grub bootloader work fine? If so you can just choose to boot to Windows from grub menu. Otherwise will you please post more information in this?
