well if you’re data is fine then great you should allways have a backup
years a go i had a similar issue
i remember that well ubuntu’s boot repair tool did jack shit for me
my prbolem was a it more complex then that and required the full recovery of a corrupted partition table basically
ther’es a nice tools for it called
testdisk
very powerfull simple and useful but at times can be horrifically slow
very simple to use lots of docu
try using that
it took hours but i completely recovered my pc… obviously slightly different of a situation but still
a powerful tool to recover data partition tables and boot sectors and alike
compared to the bs you might find when simply googleing like the ubuntu tool i
mentioned did jack shit…
it’s like trying to use Windows automatic problem solver… sure some times it’ll by chance work and do something useful but for the most part
don’t waste you’re time on those tools and… you’ll just waste hours of you’re life
seriously man… the heavy artillery is best
even if it’s slow
if it’s a hhd we’re talking about then you should maybe try using you’re backup image on another drive to play around and maybe find the issue and solve it faster…
(always have a backup much easier then to recover)
