#

do either the main install or the live session boot fully?

#

not following this. so the latest pic right above this message is the "fully installed" attempt to boot?

#

and if you were gonna attempt to boot the Live USB this very second, it would go nicely to the Mint Live desktop?

#

I suppose you'll have to find a way to enter your bios settings and check up on two things. a) the boot mode and b) precisely what is in the boot priority order

#

turn off the computer and then turn it back on. watch the screen very carefully for a key to press in the first 4 seconds of powerup

#

so plug the usb-ssd in, then pick EFI boot from that icon "boot camp" thing, then choose the 'ubuntu' or grubx64 efi file.

i vaguely remember cases of grub messed

#

it's cuz windows was on that particular ssd b4 prob

#

was it?

#

cuz u could probably fix that up

#

do u have a Windows computer to test the drive with?

#

do u have the Mint iso as a single file?

#

on ur Mac hdd?

#

np

#

let's try something different

#

mac is from what year?

#

ok koo

#

ok go on ur windows computer

#

go to website ventoy.net and get that flasher program

#

comes as zip file

#

then step by step

#

ok have ur usb to work with in the port, none else

#

then launch ventoy2disk from the decompressed ventoy folder, then

#

go to option menu

#

alter only one thing:

#

part'n style: GPT

#

then ensure it found correct flash drive shown in main vtoy installer window

#

then if so, click Install

#

after that verify the ISO on the hdd of the windows computer

#

if it checks out, copy and paste it to the empty new "ventoy" usb

#

****To verify checksum from Windows:
Open Powershell, and navigate to the folder the ISO is in, then type
Get-FileHash "nameoffile.iso" -Algorithm SHA256
or, don't navigate to location, but specify it:
Get-FileHash -Path "C:\samplefolder\samplesubfolder\nameoffile.iso" -Algorithn SHA256

#

(one space after word path, then double-openquotes)

#

then compare that calculated hash to the sha256,txt file contents on Mint website near download links

#

I forgot what your actually really trying to do

#

oh now I remember and u couldnt get it to boot up

#

@wanton terrace

#

Ventoy your external SSD. then slap the Mint ISO on it, then set up persistence on it.

#

save and maximize that text file, so u can read it fully and easily.

#

step 22 choose the 4 GB ext4 casper file

#

(you can grow it later too if needed)
