I decided to update my windows 7 install to windows 10, after which my grub was lost. So I used an ubuntu live usb with boot-repair and it found my win10 install. But I no longer have the option to boot into ubuntu. The partitiontable says its in extended space. How do I recover ubuntu? (system= x220 dualboot windows 10 + ubuntu 14.04)

Open terminal in Windows 10 (Administrator Mode)

Type bcdedit /set {bootmgr} "path\EFI\ubuntu\grubx64.efi"

Reboot. See if this helps?
