George, different stick = different UUID code => you have to change the save.dat's code in the porteus.cfg file. The same is true if you reformat the original stick.
(so far I've always used ext4)
If you use a Linux format you don't need a save.dat file.

Also, IMO journaling formats are not good for flash drives. Overhead and they are not disks so not needed.

Hey Ed, checking who's the sender of a msg really helps:

tmsg != George.
Anyway, my post was simply a +1 for Fanthom's suggestion to show the relevant information.

You porteus.cfg file looks good. Your cheatcode looks good. Lets try one more time from the beginning and if changes aren't working we will move onto creating a linux file system partition if that is an option.

Please create your porteussave.dat and change the name to mysave.dat (just to remove confusion) and place it on the root of your USB device. That means on the USB device you should have the folder boot, porteus and a file called mysave.dat
Be sure that you have only one install of porteus on the USB, and that no hard drive porteus install might be getting picked up.

Here are the changes= cheatcodes you should try.

changes=/dev/sdb1/mysave.dat
changes=/mnt/sdb1/mysave.dat
changes=UUID:E8FB-6830/mysave.dat

If you see the message during boot about creating the .dat file then the changes= code did not work.

Hi guys
Could it be that his (George) bios is still set to boot in uefi and not in legacy (bios) mode?
I have no experience with uefi but i found a comment "made by brokenman" about Changes:

Changes can be made permanent by adding this line into the boot config file.
If you are booting on UEFI then it is /mnt/sdXy/EFI/BOOT/refind.conf
If you are booting with BIOS it is /mnt/sdXy/boot/syslinux/porteus.conf

It could well be. At the boot screen menu, do you see a picture of a house on the water, or a purple screen with a porteus logo?

I followed these instructions and still couldn't make it to save changes. After I reboot I'm back to where I started, even though I can see the mysave.dat file in the USB root.

I see the Porteus logo across the top of the screen, and underneath I have choice between the two boot icons- Windows or Porteus, with F2 offering more boot options.

I think perhaps this is an EFI/BIOS related problem, as Donald suggested. I'll just start over - I'll build another ISO, and mount it on another laptop, to see if that would take me anywhere.

Hi George
It seems you have the efi boot screen which in turn means that you have written
the changes= line into the wrong File = porteus.conf.
you need to write this line into the refind.conf (/EFI/BOOT/refind.conf)
But because i do not have any uefi system I'm not able to provide the proper
syntax and place.Someone else will do...stay tuned.

And this worked! I reformatted the SanDisk 16gb USB3.0 flash drive, built another ISO (KDE4, with EFI support), booted the Toshiba laptop from it, created the mysave.dat file in root of hte flash drive, changed porteus.cfg to specify the path to the .dat file ('changes=/mnt/sdb1/mysave.dat'), and created a blank file "stay-with-me.txt" on the desktop. Rebooted, it was still there. Rebooted into Windows 10. Then rebooted again into Porteus, and my file was still there on the desktop. During rebooting there was the beach house with the Porteus logo (as opposed to the purple screen).

Next, I'll try that USB drive back on the Lenovo laptop again and see if it would work. Love the KDE4, by the way, but it's a bit slower.

Thanks Donald. Apparently that's the problem on the Lenovo and I will await instructions on how to modify the proper file. After I tried the same USB that worked on a friend's laptop, I booted again on my Lenovo, and the test file was no longer on the desktop.

Ok George, Donald is correct :good: you're booting on a UEFI machine. My flash drive boots on BIOS and UEFI systems also so I think I can help you.

In BIOS mode the changes to the /boot/syslinux/porteus.cfg file at line 41 are what you need and apparently have done.

In UEFI mode the changes to the /EFI/BOOT/refind.conf file at line 470 are what you are interested in along with:

1. You will need to disable the UEFI machine's Secure Boot option.

2. You need to change line 470 to match the name and location of your save.dat file.

3. When you boot on the EFI system you need to select the Porteus icon then press F2 to see the Porteus menu option for "Save changes".

Once you get the drive to boot on the UEFI system and to Save Changes we can talk about making that the default option. :)

Ed, it worked! Thank you!!!

I edited /EFI/BOOT/refind.conf to add the path to my .dat file on line 470 and rebooted in "Save Changes" mode without any issues. However, I couldn't disable "Secure Boot", because I can't find such a switch in the BIOS settings of this machine. That's why I abandoned my original plan for a dual- boot setup on the hard drive and decided to use a live USB instead.

Now, how do I make "Save Changes" the default boot option on a UEFI machine?

George

Not exact model but try this howto disable secure booting in bios
https://docs.fedoraproject.org/en-US/Fe ... 02s02.html

Just remember that Windows 8 onwards needs secure booting on to enable it to boot up.

Rant starts
Can anyone explain why there is no windows 9?
Do Microsoft users actually think their operating system is more secure than Linux because they need UEFI secure boot?
Rant ends

I propose they thought
A it might reduce the uptake of Linux as so many people were still on XP
B they had no way to solve their problem with the hidden sector malware in the second 512 bytes just past the MBR.
