#StackBounty: #dual-boot #grub Win10/Ubuntu dual-boot – Locked out of grub

Bounty: 50

TODO: A title that makes more sense

So, I’ve managed to get Windows 10 and Ubuntu 14.04 LTS dual booting — I have grub set to come up for a few seconds on boot so I don’t have to mash F12 when I want to boot to Linux (windows is the default). It’s been working perfectly for a few months.

Just now I tried to boot to Linux, and Grub helpfully didn’t come up. I tried a few times, no such luck. I checked that it was actually booting to Grub, not windows boot manager by mashing F12 on boot and choosing Grub (the default). That didn’t work either.

I haven’t done anything that ought to affect anything.
Ubuntu 16.04 LTS, installed from USB


Maybe this is a silly question and I’m just doing something terribly dumb.


Thanks!

I’ve borrowed a linux-on-a-stick drive from a friend, so I can run from it and edit Grub’s config files. I could delete the secondary partion (from windows’ partition manager) and reinstall, but that that takes forever so if anyone has a simpler solution that would be great.
