I'm trying to find a work-around for another question: "Ubuntu 18.04.2 sometimes hangs from Suspend or reboot."

My desktop boot process often hangs. Is there a way to load just the necessary boot files on a thumb drive that will boot my PC to the hard drive? I have some thumb drives that boot to an OS on themselves. But I need to boot to my hard drive.

    You can install Ubuntu (or to make it smaller and faster: Lubuntu or Xubuntu) to a USB drive like you install to an internal drive. See this link. Then boot into your new system in the USB drive and run sudo update-grub. This should find your system in the internal drive and create a menu entry in the grub menu for it, and you can select to boot into it. – sudodus Jun 16 '19 at 18:17
  • BIOS or UEFI? You can install grub to any drive, but generally best to have it on the same drive as your Ubuntu install. I have multiple full installs on flash drives and add to 40_custom boot of some of my HDD or SSD partitions. Use labels and configfile to boot another install askubuntu.com/questions/344125/… & gnu.org/software/grub/manual/grub/… – oldfred Jun 16 '19 at 20:12
