Sorry, i can't understand o.O

At the link @oldfred provided, there's a link to a page about a tool called "boot repair." One of the options provided by the tool is to create a text file containing diagnostic information that might be of some help to the community members who are trying to help you.

Just wanted you to run & post link to summary report from Boot-Repair.
It will not fix Windows but may show issues.

But i should install on my ubuntu or use it with the iso in a usb? xD i can't understand that, sorry

[oldfred]

You can run it from your live installer, the flash drive you create to install Ubuntu from the ISO.

Here is the summary:

And report shows issues with your NTFS main partition sda2.
But sda1, the Windows boot partition seems to be ok. Can you boot to Windows recovery mode with f8?
Grub usually boots into Windows too fast for the f8 key to have time to be pressed. One user posted that after trying many times and being really quick he did get it to work. But typically you have to temporarily reinstall Windows boot loader to MBR of grub. You still have grub in MBR.

You can reinstall the Windows boot loader from your Windows repair disk or Windows install disk with repair console.
Boot-Repair may let you install a Windows type boot loader since it can see sda1. In advanced options see if you can choose Windows & sda as drive to install into. If not only a Windows repair disk will work.

Moving to the Windows sub-forum.
We only know minor Windows fixes, some of us do dual boot and they may look in Windows sub-forum.
Best to ask on a Windows forum. But post issue not long video.
I think Windows 7 also expires next year.

Now i fixed that, using a rescue disk and chkdsk.
But when i try to boot i have the error "No such partition, entering rescue mode".
I booted Windows with supergrub2, but how can i recover my ubuntu dual boot grub? :s sorry

Use the Ubuntu 'live' usb and repeat the process to get and run boot repair and post the new link since things have changed.
