I am trying to setup an older PC (Yes it can boot to USB) with Ubuntu and have only the /boot partition on a USB Thumb drive. Not running the operation system from the USB but to have the OS installed on the internal HDD and only the /boot on the USB Thumb drive, I do not want to run the operating system from the USB Thumb drive.
What i would like to do is. plug in the thumb drive and boot the computer and login.
If no thumb drive is plugged in when the computer is turned on, it will not boot up due to the lack of a /boot partition.
After many attempts I have been able to get it to work, BUT .... after a kernel upgrade the system will no longer boot to the desktop but only dumping into (initramfs) prompt with a warning that UUID=blablablabla does not exist, which is the thumb drive. doing a blkid command will show the thumb drive in the list but only with a different UUID.
so then I decided to try using the label of the thumb drive instead of the UUID in the fstab, this produces the same results after doing a kernel upgrade.
I can reboot the system all day long as long as i do not upgrade it.
I just don't get it.
I have searched Google / Yahoo many many times for the past week now, trying different variations of boot from USB with no luck, perhaps I'm just not wording it correctly?
Any one know of a guide or perhaps how to do this?
Any help would be greatly appreciated. Thank You.
