I've been trying to install mint on a USB, and got it to install on 2 seperate USBs, then finding out that i need to use one to boot and the other to install. I now get import_mok_state failed not found apon booting either or. Oddly, BalenaEtcher wont detect my iso anymore aswell so i have resorted to using rufus. I have formatted and removed all of the partitions from the USBs multiple times. I cannot disable secure boot because the option is grayed out in my ASUS laptop's BIOS; although this shouldnt be an issue as I used to be able to boot on the same PC with the same USBs.

#

also note that i have run diskpart cleaning and removing partitions

strange sage
#

use ventoy with its secure boot support enabled (default setting)

sage wigeon
#

which one?

strange sage
#

note, installing onto another usb for daily usage isnt recommended. will break the usb stick over a few weeks if used a lot

strange sage
#

use gpt in options

sage wigeon
#

alright, and installing mint through etcher or rufus should work fine now?

see full vid then

sage wigeon
#

my installation USB is quite slow, thanks for your support. I'll get back to you if it works or not.

strange sage
#

use the DISKS app so u sort out and fully understand which disk is which BEFORE u run the installer icon on the desktop

#

it's in the start menu in 'Accessories' once u live-boot Mint to desktop

sage wigeon
#

thank you

strange sage
#

tbh u should take the windows disk out

#

so the bootloader doesnt automatically end up on that (and it will)

#

@sage wigeon

sage wigeon
#

taking the windows disk out isnt really an option

strange sage
#

then u gotta pick 'something else' option in installer

#

and do full manual

sage wigeon
#

dang

strange sage
#

which isnt hard, i'll show u the pic

sage wigeon
#

thanks

strange sage
#

so example: ur ventoy'd USB (the installer disk) we'll call USB1

#

the target to install onto, we'll call USB-2

#

in DISKS app sort out which is which. (USB2 identify it by size or brand) and it may have a name like sdc perhaps

sage wigeon
#

it boots

#

if you don't mind me asking and you by chance know, how come Ventoy works but etcher and Rufus didn't?

strange sage
#

it's just better, especially if u put it to GPT as my pic showed

#

Manual example:

#

in the example above, the target disk happens to be sda. replace with ur target
note the red text precisely
use the + sign to make new partitions from raw space
use the "change" button to set parameters, such as the first partition must be set to be "EFI system partition"
and the second asterisk shown for the main linux.

#

Again, make sure to run the DISKS app and learn ur disk dev names so u dont F up hardcore.

#

@sage wigeon ^

#

make sure those 3 red asterisked items are set accurately n ur good to go.

#

dont need the home or swap things there

sage wigeon
#

alr ty

#

my 2nd larger USB where I want to put the OS has mint installed in it, should I format it before installing?

strange sage
#

nah

#

u set the settings as shown in pic, and tick the format box there

sage wigeon
#

ah

strange sage
#

u may want to make a new partition TABLE first

#

u can pick the right disk and pick the new partition table button in the installer n make it GPT

#

then after hit the + to make the two things, EFI, and main

#

note: that new partition table button will wipe the disk so make sure u highlighted the correct dev name

sage wigeon
#

if you don't mind me asking what does the table do?

strange sage
#

erases all file structure on the drive

sage wigeon
#

alr

strange sage
#

and GPT is the new standard for newish computers that run UEFI

#

(GUID Partition Table)

sage wigeon
#

in the change window should I change the use as to something else or is Ext4 good?

strange sage
#

yeah as shown

sage wigeon
#

seems good, I'll install

strange sage
#

the EFI partition must be marked 'use as : EFI sys.ptn' and only needs be around 100 MB

#

and the bottom dropdown with red text is absolutely vital to follow

sage wigeon
#

it worked, I'll be closing the thread

Leave it readable/searchable incase others can find this useful.
