Thread: Install with only /boot partion on thumb drive

i trying setup older pc (yes can boot usb) ubuntu , have /boot partition on usb thumb drive. not running operation system usb have os installed on internal hdd , /boot on usb thumb drive, not want run operating system usb thumb drive.

is. plug in thumb drive , boot computer , login.
if no thumb drive plugged in when computer turned on, not boot due lack of /boot partition.

after many attempts have been able work, .... after kernel upgrade system no longer boot desktop dumping (initramfs) prompt warning uuid=blablablabla not exist, thumb drive. doing blkid command show thumb drive in list different uuid.

decided try using label of thumb drive instead of uuid in fstab, produces same results after doing kernel upgrade.

can reboot system day long long not upgrade it.

don't it.

have searched google / yahoo many many times past week now, trying different variations of boot usb no luck, perhaps i'm not wording correctly?

1 know of guide or perhaps how this?
appreciated. thank you.

i not put /boot, grub , maybe grub in mbr of flash drive. , leave /boot inside install's / (root) partition.

install can install grub2's boot loader drive. if flash drive sdb.
#reinstall working (not livecd/dvd/usb) system - first find ubuntu drive (example drive sdb use drive not partitions):
sudo fdisk -l
#if it's "/dev/sdb" run:
sudo grub-install /dev/sdb
#if returns errors run:
sudo grub-install --recheck /dev/sdb
sudo update-grub


or can create grub bootable flash drive. flash drives have grub. have manually maintain grub.cfg file. use grub on flash drives (and hard drive) boot iso directly.

above can have simplied grub entry not require maintenance when kernel updated.

first saw ranch hand
note not define kernel. defines partition. boots newest bootable kernel finds @ partition. example based on sda13 change 13's partition number.
@ least ubuntu family os's, place symlinks in /, called vmlinuz , initrd.img these point recent versions of kernel in /boot folder.
