I used to have two harddrives sda (Ubuntu 12.04LTS) and sdb (Window 7). I used grub2 to boot between both of them.
Then, I did a clean install of Ubuntu 13.10 on sda replacing the old Ubuntu version. I think, this install automatically changed boot to UEFI if I'm not mistaken.
Now, the Windows boot option doesn't show up anymore in grub menu and I have no way to boot into my Windows 7 installation anymore, which I need to do occassionally.
How can I restore it? Do I need to revert back to a previous boot mechanism prior UEFI (which one?)? What would be of interest to debug this?
sdb1 is the boot partition of Windows 7 (ntfs)
My Linux partitions are encrypted.
