hi, for a completely different approach: i had windows 8.1 and Linux dual-booting using uefi: windows set itself up how it liked then i created another uefi boot menu item with efibootmgr that pointed to my efistub enabled linux kernel, with its cmdline built-in switching what booted was done by pressing the key the uefi system set to access its "bootmenu" for me it was f12 also there should be no technical reason you need to keep secure-boot disabled - all uefi systems i have worked with have advertised being capable of accepting user keys, whether this is useful or not is a whole different question... ( admittedly i have never tried to use this feature ) aaron m _______________________________________________ Linux-users mailing list [email protected] http://lists.canterbury.ac.nz/mailman/listinfo/linux-users
