As per title, I cannot boot to Ubuntu 12.04 after upgrading from W8 to W 8.1. I have read several topics on this forum, but I don't seem to be able to solve the problem. I have tried first with Boot-Repair, but it didn't work. I have also tried with the guide at How can I repair grub? (How to get Ubuntu back after installing Windows?) but it did not work either, although I got no error messages (I also tried step no. 7).
I am not sure if I am not identifying the right partition or have some other problem. This is getting annoying and time-wasting. I am quite a noob with Linux, but I do need it for work. If I type:
ls -l /dev/disk/by-label/
this is what I get:
lrwxrwxrwx 1 root root 10 Feb 26 19:03 Recovery -> ../../sda5 lrwxrwxrwx 1 root root 10 Feb 26 19:03 System -> ../../sda1 lrwxrwxrwx 1 root root 10 Feb 26 19:03 TI10664600J -> ../../sda4 lrwxrwxrwx 1 root root 9 Feb 26 19:03 Ubuntu\x2012.04.3\x20LTS\x20amd64 -> ../../sr0
(TI10664600J is the Windows partition)
I think I need some help...
sudo parted -l

I am not sure now which partition I should mount to then install the Grub . As an alternative, should I try to install it on all of them?
OK, second edit: after starting Windows, I can shift-click on restart. Doing so prompts me to a menu when I can choose to boot from a device --> I can choose to boot Ubuntu. The computer restarts and the grub kicks in, with the normal dual boot menu. So, it looks like the grub is still there, it is just not starting when I turn the computer on.
