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.

Thanks

    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](https://askubuntu.com/questions/16988/how-do-i-install-ubuntu-to-a-usb-key-without-using-startup-disk-creator/942312#942312). 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 https://askubuntu.com/questions/344125/how-to-add-a-grub2-menu-entry-for-booting-installed-ubuntu-on-a-usb-drive/344359#344359 & https://www.gnu.org/software/grub/manual/grub/grub.html#Multi_002dboot-manual-config – oldfred Jun 16 '19 at 20:12
