I have a chromebook. Linux is on it but I wanted a copy to boot from USB. Legacy boot is enabled and I was able to boot the install/live cd via USB. I installed to sdb and installed grub there too. To boot to chrome I press ctrl+d. To boot into linux or the USB I press ctrl+d. When I try booting to the USB it skips it like it doesn't exist and goes to linux.I used fdisk and set the bootable flag but it didn't seem to solve it. Grub shows set root='hd1,msdos1 which I believe is correct? The USB should always be loaded at /dev/sdb. I have no idea what to do/change besides making sure grub exist on the first partition and making sure it's marked as bootable. I'm not sure how much this affects things but it's an encrypted LVM partition. When running Linux via chromebook I get a prompt to unlock the partition but I only want to boot from this
After installing debian (to a USB stick) it won't boot
debian;boot;grub
