Boot script tells a lot, but BootInfo would show more. You have UEFI system with gpt partitioning and grub installed in a BIUOS/MBR partitioning mode. Ubuntu liveCD/USB needed to be booted in UEFI mode to install correctly. You also managed to install grub to severa partitions but that should not matter, but will never be used.

If Windows files are ok, script does not show them, you can use this to fix Ubuntu. Boot-Repair runs the boot info script as part of its BootInfo and adds some extra info that will tell us if your Windows boot files are still there.

Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
https://help.ubuntu.com/community/Boot-Repair
You can repair many boot issues with this or 'Create BootInfo' report (Other Options) & post the link it creates, so we can see your exact configuration and diagnose advanced problems.

I hope you can help me

You have a UEFI system and both Windows & Ubuntu installed in efi mode. But you then install grub into the MBR or old BIOS mode and installed it into several partitions. Not sure if install into the efi partition will prevent booting or not. Windows normally has to have its boot info in the partition boot sector.

Are you in UEFI/BIOS choosing UEFI and booting from that?

But you can fix the Windows partition.

Code:

sda3: _____________________________________

    File system:       ntfs
    Boot sector type:  Grub2 (v1.99)
    Boot sector info:  Grub2 (v1.99) is installed in the boot sector of sda3 
                       and looks at sector 85290144 of the same hard drive 
                       for core.img. core.img is at this location and looks 
                       for (,gpt4)/boot/grub on this drive. No errors found 
                       in the Boot Parameter Block.
    Operating System:  Windows 7
    Boot files:        /Windows/System32/winload.exe

Fix for most, a few have other issues, better than windows fix in many cases as it also fixes other parameters:

This has instructions on using testdisk to repair the install of grub to the boot sector for windows from Ubuntu or Linux LiveCD. Note your drive is gpt(GUID) not MBR(msdos).

If UEFI boot does not work we may have to backup the efi boot files in sda1, and totally reformat it, then restore boot files.
Update.
Testdisk site says this. So also try to run same repair on sda1.

Recovery of a FAT32 partition (instead of an NTFS partition) can be accomplished by following exactly the same steps.

oldfred +1 (you need to fix the bootsector of sda3)

However, i see you are able to boot into your installed Ubuntu in UEFI mode:

Code:

BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.

so you probably don't need to fix the bootsector of sda1.

So i would:
1) fix the bootsector of sda3 as described by oldfred
2) reboot the PC, in the GRUB menu choose the "Windows UEFI" entry, and tell us if it boots Windows or not.
