You don't run update-grub from a live session; you have to chroot into the install and run it from there, where you are running the correct version, regardless of how you booted the livecd. >> an EFI booting system can't have a bios booting windows install. > > I am nearly sure of the contrary, because many preinstalled Windows > come with both files to be booted in UEFI and Legacy modes. > Examples: http://paste.ubuntu.com/1495850, > http://paste.ubuntu.com/1479512 , http://paste2.org/p/2700549 Maybe it has the files there anyhow, but is it possible to install windows on a gpt disk without EFI? Either way it's a moot point though since you can't boot windows in a mode other than the one grub is booted in. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iQEcBAEBAgAGBQJQ7Ph2AAoJEJrBOlT6nu75ccgH/1b2NXUnpoQN/jiO0y+22HBs eKPX1Z330ocTeJhl56g+CFtiUuHGpwOu9mzmQTbaeKKSuGWboDe7XW8lXOxd2JaC Cozpw8zQa8KxOic+EsrqNWPk68Wy9Xy5EtOoSygCxEZwo9HXm1bhGwIvBEYq8pn7 gcM4w+LNh25QnMDctkTTxKezQyrF8zSVziomybEBRy1tXt3ai5ENqrWv4MUyIjxk 249oCwcJrrtYNEfaFNZyAIincoFMLd4IeiM3f0lyvvoSZZa4WlgAh/mGu/qxfThe CNieL5KZcc9WEtThtAcstoZOLOfh76HykO04iEsZ6h7tmj+dJxkltqXbhcxpmmY= =fREm -----END PGP SIGNATURE----- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024383 Title: update-grub generates only BIOS based menu entries for Windows, even on UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1024383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
