Windows 10 and Ubuntu 15.04: any chance to get along?

Question

Windows

The problem is this. I have a flash drive with Ubuntu and a disk with Windows 7. Previously, everything worked fine when installing according to the algorithm:
1. Install wine,
2. Install ubuntu.
And then everything was fine: after installing ubuntu, grab 2 was immediately installed, in which all the necessary items were perfectly displayed: both Windows, and ubuntu, and memtest. But now, with the release of 10, some problems have appeared.
The fact is that after updating the wines to 10, when trying to install ubuntu, the installer finds the seven (logically, because the wine leaves a copy of the seven in the windows.old folder, so that you can roll back later). But the item "Install next to Windows 7" is no longer there. Although there is an inscription "Windows 7 was found on your computer." Is there any chance to install them together so that everything is displayed normally in the hornbeam?
There was another option: immediately put the seven, then Linux (with the seven everything is set up quite normally, everyone finds each other and everyone is happy), and then update the wines to 10. But when I did this, the “Windows 7” item remained in the hornbeam anyway " (and not 10, although the 10th was loaded). Therefore, thoughts immediately arose that as soon as the windows.old folder is deleted (and this will happen in a month), then the menu item in the hornbeam will fly off along with the ability to launch 10-ki.
How to be?

No, the item in the hornbeam will not fly off.
The grab does not find windows.old, but the Windows loader. He just doesn't care 7 or 10. Rename the item if it confuses you.
