Yeah it is complicated , when you look at a freshly written USB stick with gnome disks there is a box you can tick that says Legacy BIOS bootable , I'm not sure if gnome disks is doing as described below with the "bios_grub" flag as the link talks about a hardrive so i'm not sure if it would apply to a USB stick?
https://help.ubuntu.com/community/DiskSpace >BIOS-Boot or EFI partition (required on GPT disks) >The BIOS-boot partition contains GRUB 2's core. It is necessary if you install Ubuntu on a GPT >disk, and if the firmware (BIOS) is set up in Legacy (not EFI) mode. It must be located at the >start of a GPT disk, and have a "bios_grub" flag. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922342 Title: HIrsute live session takes ages to boot on BIOS systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1922342/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
