Brakuje partycji rozruchowej Windows - o ile w ogóle była. Powinno być coś takiego;
W jaki sposób i w jakiej kolejności były instalowane systemy?
Pierwsza została windows 7(jeszcze wcześniej) później 10 a przy instalacji linuxa sformatowałem partycje z 7 i zostawiłem 10
PS: Windows 10 jest na sda4 (jest jeszcze jedna partycja, największa jest na moje pliki, w windowsie to była partycja F:\
Na forum piszemy w języku polskim, używamy “ś, ć, ź, ż, ą, ę, etc.”, oraz znaków interpunkcyjnych proszę użyć przycisku EDYTUJ , który znajdziesz w prawym dolnym rogu posta i dokonać zalecanych poprawek w treści posta/ów i tytule wątku, tytuł możesz edytować po użyciu zaawansowanego edytora, dziękuję za uwagę.
No tutaj jest tak zwany pies pogrzebany 
Partycja “Siódemki” trzymała pliki rozruchowe Win10. Nie umiem powiedzieć czy można zmusić instalator Win10 do naprawy przez umieszczenie / odtworzenie brakujących plików na /dev/sda4 zamiast “starych” lokalizacji na partycji z nieistniejącą siódemką.
O nie! Co radzisz zrobić 
Uruchomić komputer z płyty instalacyjnej Windows 10 i wybraniu języka zobaczyć co jest pod pozycją “Napraw komputer”. Ponieważ to jeszcze beta to nie wiem jakie mogą być efekty zabawy różnym narzędziami przywracania. Możesz to najpierw sprawdzić na Virtualbox w linuksie jak to wygląda.
Też o tym myślałem, instalator działa identyczne jak z 7 więc myśle ze da rade 
ale na jaką partycje przywróci pliki rozruchowe??? 
jakie pliki mam skopiować na partycje z windowsem???
Naprawiłem mbr z instalki windowsa ale przy włączaniu komputera widze tylko migającą kreskę i nic. Co robić?
