I was careless and just clicked all HP updates in Windows 10 (>1GB) for my Pavillion x360 and went for a walk. Now that I come back I have lost dual boot.

The Ubuntu partitions are still there: https://i.sstatic.net/6AeM1.png I assume E=swap, F=root, G=home

The computer previously booted Ubuntu 16.04 and Windows 10.

I looked in the UEFI and pressed enter for the Ubuntu alternative. But still only Windows boot. https://i.sstatic.net/35cPn.jpg

Please tell how I can get dual boot back.

Thank you

It is my experience that Windows updates knock out the dual boot process. How exactly, I don't know. I fix it either by reinstalling Ubuntu (there is an option that repairs and saves your files) or; with USB bootable stick and recovery mode. In recovery mode, various options will clean & repair the grub entries.

This is a very common problem. When it happens, I go to BIOS and change the Boot order, then reinstall grub.

Here is the answer I use (I have it bookmarked): How can I repair grub? (How to get Ubuntu back after installing Windows?)
