linux and windows already installed, setting up grub


I have a system that has windows 10 and ubuntu 14.04 on it. However, it now longer presents the boot menu, it immediately boots to windows. How can I reinstall grub to get my dual boot capability back again?

supergrub2 usb boot, it will find OS'es and boot into your Linux system then handle your grub from there.

tricky, because your machine likely uses UEFI.
anyhow, try these.

Not enough information to do more than guess. One frequent cause of this problem is that some windows 10 updates will rewrite the partition table and not include non-windows partitions. Did you recently do an update on windows? If you are using 14.04, the dual boot was apparently working for some time, correct? What other changes if any, were recently made? Are you using the default UEFI for both windows and Ubuntu? If you have not resolved this problem, use the Ubuntu installation DVD/flash drive and go to the boot repair site below. Use the 2nd option to download and then run it per instructions on the page selecting the option to Create BootInfo Summary and do not try to make repairs. Post the link it gives you here and someone should be able to advise you.
