I am trying to boot from my USB Stick which has the new LinuxMint 22.2 .
But when I select Install Linux Mint (even in compatibility mode) I get the busybox text:
(initramfs) stdin: Invalid argument
mount: mounting /dev/loop0 on /filesystem.squashfs failed: Invalid argument
Can not mount /dev/loop0 (/cdrom/casper/filesystem.squasfsh) on /filesystem.sqashfs
I had Bios version 3.17 before but updated to 3.24 (still the same issue)
I also disabled quick boot ( I heard of some usb disconnection during boot)
My other laptop can boot from this stick.
But my Framework 13 (11th Intel( still runs into this issue.)
I had no such problems before. Is it because of my current btrfs / luks setting of omarchy?
Just checking you have secure boot disabled too?
Just looking on the forums for similar issues, some people had success using ventoy to burn the USB. I just installed LM 22.2 yesterday using belena etcher. other things to try would be grab a different USB. maybe try 22.1 and then once installed you can use the built in upgrade tool to get to 22.2 in the update manager. If you USB works on a different computer though that would point towards a bios setting. I’m no expert unfortunatly
Hi Douglas, thanks for your reply.
Secure boot is disabled.
Yes I used ventoy , but it runs into „invalid magic number“ on boot , for some reason.
Good hint with the 22.1 option, will test it out.
No worrise, I know how frustrating these things can be.
Other things to try are multiple USB drives. I have in the past had to try 4 drives I had lying around until I found one that behaved. This is also very commonly the issue on forums. Best if you can get one that you know is legit, such as a Sandisk of know origin.
Im curious if you get the same issue with Fedora, not for you to use but just to trouble shoot.
The Linux Mint forum is generally full of people who know far more than me
I just followed this step by step:

just for sanity check
Are you trying to dual boot?

Hi Douglas ,
Thanks again for your response.
I disabled secure boot.
But you had the right guess. After trying several usb sticks , I bought a new one and it worked.
I bought the SanDisk Ultra Dual Drive Go 128GB USB Type-C
Before I used a KingstonTraveler and a random one.
But weird that those ones were working on my other laptop.

Great, happy to hear of your success!
that is strange, kingston isn’t exactly a back street brand. I am out my depth as to why some work and others don’t. five years ago I was installing fedora, failed repeatedly on a 64gb sandisk USB (Tbf, I had bought it cheap off amazon so could have been fake) then out of desperation tried a random 4gb one I had picked up for free at a fair, you know the type, and it worked like a charm.. I suspect this is a case of several variables to which i am ignorant which gives the impression of black magic.
The fact that it worked on one laptop but not the other though.. and then changing the stick fixed it.. for me as an engineer that does not sit right. but then again I have more than once questioned whether V = I x R 
If I had to form a theory, something on you FW13 had gotten into a bad loop with mounting a USBA and switching to USBC took it through a different channel/ procedure/ bypassed the problematic part of the sequence. So maybe if your old stick worked on another laptop, it probably was okay but for whatever reason the USBA driver, cache or something had an issue. Maybe that loop will have self fixed now you have successfully installed, maybe not. But now you have a working stick and a new trick to try if you get an issue in the future
I am glad you are up and running
Enjoy mint
