I know this question has been asked several times but all the solutions I found googling didn't work at all.
I am not sure if this is a grub issue or windows 10 issue.
So, I had a disk with Ubuntu 14 installed and another one with Windows 7 installed. Windows 7 was a bit laggy since I had a bunch of junk files there so I decided to format and install Windows 10.
As everybody might know, Windows 10 replaced grub, so I went into my Ubuntu Live CD to install grub and updated it. However, when grub finally launched, it indeed shows a Windows partition, but it says "Windows 7". When I boot it, I get a Windows Bootloader error (0xc000000f) and I have to reboot.
My ubuntu partition boots fine but I get an error when I try to open my Windows partition :/
As an alternative solution, I downloaded boot-repair but it didn't work at all. The logs show some errors.
