Rather than to install dual-OS on my laptop, I would like to install Ubuntu on my flashdrive (USB flash memory, or whatever you call it). So, whenever I want to run my Ubuntu, I will just plug my flashdrive to the USB port and run it from there by change the boot sequence in BIOS.
Is it possible?
Best Answer
Full Install to USB
11.10 is too old, Latest LTS, (Long Term Service), release is 18.04.
Full installs are more stable and secure than persistent installs, but not as quick to make. They are better at utilizing disk space as no fixed size casper-rw file or partition is required. They are not very good for use of installing Ubuntu.
Following is a step by step how to install 18.04 on a 16GB flash drive with options for separate Home partition and Windows compatible data partition:
(Optional FAT32 data partition for use on Windows machine)
(Non Optional Root Partition)
(Optional home partition)
(Optional swap space, allows hibernation)
(Important)
Click "Install Now".
Select your location.
Note: You may omit disabling the hard drive if after partitioning you choose to install grub to the root of the USB drive you are installing Ubuntu to, (ie sdb not sdb1). Be cautious, many people have overwritten the HDD MBR as default location for boot loader is sda, any items in the internal drive's grub will be added to the USB's grub. You may do an update-grub later.
