I am running AntiX 8.2.3 Testing on a flash drive. Any thing I change in settings gets saved to root "/" partition on my flash drive. The way I had to get to this point was
1. Format a 2gig flashdrive using gparted as fat32 file system.
2. Download the distro of my choice (for you Linux Mint) and save to my Desktop.
3. Downoad md5sum number to Desktop OR copy and paste md5sum number into a text file like gedit,leafpad, or whatever text editor you use.
4. Open Terminal and type in
Hit Enter
5. Then type in
Code:
md5sum <you put name of downloaded mint iso file here>
Hit Enter
6. Compare that readout number with the md5sum number in your md5sum saved document file on your Desktop and make sure they match exactly.
7. If everything checks good, you have a good iso to now install to USB.
8. Here is where I will tell you how to try a different route on installing a Linux operating system to a Flashdrive then what you have been trying.
Before I go any further, I use a 2 gig flash as a live USB CD Installer.
I use a 4 gig Flash drive to load the final version of my operating system onto.So if you want to follow my instructions you will need 2 flash drives and 1 will need to be at least 4 gigs.
9. Go to
Unetbootin and download either windows version or Linux Version and save to your Desktop.(I don't know what you run for a OS)
10. Plug in you fat32 USB Flashdrive and make sure it is mounted. (shows up)
11. Open up Unetbootin and use it to install Mint to the flashdrive. It will let you know when it is finished.
12. Now boot up your Flash drive you just made and after you log in to desktop. Insert your 4 gig flash drive.
13. Pick the install option from your live CD that is running and make sure that you pick out the 4 gig drive as the destination for your install. When given the option to open Gparted during install process do so. Format the 4 gig drive as Primary, EXT2, and label it as boot.
14. During install process designate the 4 gig drive as a root "/" partition.
15. After the install gets to where do you want grub installed to pick MBR and make sure it goes to the drive letter that gparted labled it when you formatted it as EXT2. It will be some thing like sdb1 or sdc1.
16. After grub tells you you installed successfully. You should finish up with entering root passwords and user name and passwords. Then you are done.
I gathered when you did your dd commmand that the flashdrive you are using is too small. Mint needs some room to flex its muscles.
Antix is smaller in commparison and it Takes up 2 gigs of root to run in my flashdrive which leaves me 2 gigs to save changes like what you are doing with wireless. Good Luck and Happy Trails.
