This is my first question here and I'm trying to give as much information as possible: I tried dualbooting Linux Ubuntu (first Gnome then regular Ubuntu) with windows 8 on my Lenovo U310 Ideapad. I also disabled UEFI SecureBoot and tried to install ubuntu. First I had a problem with the grub download and then I tried to format my partitions in the UI. I beleave that then did I make some serious mistake which resulted in the error. Also I used an usb stick formated with the universal usb installer from pendrivelinux.
Now if I try to boot following error occurs: "Kernel panic - not syncing: VFS unable to mount root fs on unknown block (2,0).
I don't really care about dual booting anymore, I am just happy if ubuntu could start working.
