I'm using an HP laptop with Windows/Ubuntu 18.04, but after a reinstallation of Ubuntu, I can't boot into Windows. Advanced options for Ubuntu and system settings, but I can't find the option for accessing Windows.
I don't really know what the problem is. I tried a lot of suggestions here, but none worked.
I tried the accepted answer in this question (Unable to boot into Windows after installing Ubuntu, how to fix?), after creating a file and rebooting. I could see an option called Windows-UEFI. But if I try to click on that and proceed I get the error,
error : no such device : /EFI/Microsoft/Boot/bootmgfw.efi. error : file /EFI/Microsoft/Boot/bootmgfw.efi' not found.Then I tried running the Boot Info Script (http://bootinfoscript.sourceforge.net/). The output is uploaded here: https://file.io/vuch51vB.

- I tried editing the grub-file as mentioned here (Unable to boot into Windows after Ubuntu 14.04.3 installation)
It did not work either.
At this point, I don't know what exactly my problem is. also I'm scared of messing up the whole system if I try new solutions without knowing what I'm doing. Can anyone help me to find out the problem?
