I recently installed Xubuntu 16.04.1 (x86) on my 64 GB USB flashdrive. I installed it using the installation DVD I burned.
My USB has 3 partitions (in this order):
1. 12 GB data storage for use on windows computers,
2. main install/root EXT4 partition,
3. and 2 GB swap area
NOTE: GRUB2 is installed on the correct device. Xubuntu is fully installed, not an installation ISO image.
Everything is working fine, but there is one major annoyance/potential problem: on the GRUB2 menu, it includes the option to load Windows Vista from the computer I used to do the installation.
How do I remove this option from the GRUB2 menu?
Also, is it possible that on some computers I might boot my USB from, GRUB2 might not be able to load Xubuntu (EX: on a computer w/o a hard drive, or with other USB drives plugged in)?
