So, introducing my girlfriend to Linux, I decided to install Lubuntu 12.04 on her netbook while she's away.
My goal was to have a dualboot with Windows 7 Starter and Lubuntu.
After having successfully installed Lubuntu from a LiveUSB, I was prompted to reboot as usual. Then my computer booted straight into Windows without starting grub at all!
I was able to re-enter Lubuntu from the LiveUSB, but that's still the live version, not using what I've just installed.
Details about installation
/sda/sda6 -where I installed Lubuntu AND bootloader, mounted on /
TL;DR - Dualboot Win/Lubuntu, GRUB missing after Lubuntu install
Please advice quickly, or else girlfriend will think I'm a total newb=P
