Persistence with Multiboot USB key

Hello,
I have a multiboot USB key containing Porteus 5.0 XFCE. On my USB key I have 3 partitions.
The 3rd partition is NTFS and can be used to store data.
I tried to set Porteus persistence via Porteus SaveFile Manager. The file porteussave.dat is created correctly.
In isolinux configuration, I've added in APPEND changes=porteussave.dat
At startup, it doesn't find the porteussave.dat file. However, if I put the file on another USB key containing only one partition, it detects it correctly.
Do you have any idea how to solve this problem ?
Thank you in advance for your feedback.

hi ,if you have enough space on porteus partition root, in terminal fdisk -l as root and append the line in the porteus config in /boot directory as the tread linked here
Where exactly is the append line I put the save.dat path in?

What format are the 1st 2 partitions? If you are using a save.dat file 1 of the partitions is FAT32 or exFAT. And BTW & FWIW NTFS is NOT a good USB drive format. For large files exFAT is recommended.
I think your changes= cheatcode is missing a / in front of the file's name, assuming it's in the drive's root. If its in a folder ...

Hi,
To create my USB flash drive, I use a dd and then do a fdisk to create a partition with the remaining space.
I've tried creating an ext4 or exFAT partition on the remaining space and I get the same result.
With a fdisk it doesn't give me the partition type for the 1st partition, the second is marked EFI (FAT-12/16/32). These two partitions are not writable.
beny I looked at the link you gave me and it's not what I want. I'd like to be able to have a configuration that I don't modify for each USB key I create.
Ed I tested with the / and it doesn't work.

if the 1st 2 partitions are not writable and the 3rd partition is NTFS where is the porteus system?
All my USB drives are a single FAT32 partition and boot in my EFI notebook.

The Porteus system is in the 1st partition.
Yes I see your key works in UEFI only. Mine works in BIOS and UEFI.

Mine works in both modes also.
If your Porteus system is in the 1st partition what's in the 2nd non-writable partition?

Do you have a key with a single partition that works in BIOS and UEFI ?
I'd like to know your method for creating this key and whether it works in multiboot.
If it's in the official documentation, I may have missed something.

Code: Select all
## Run GParted to partition & format the USB drive with a msdos Partition table. ##
## Use GParted's View > Device Information to check Partition Table type. ##
## Use GParted's Device > Create Partition Table if Partition Table shows as GPT.##
## Or under Windows use: ##
## > diskpart * Run Command Prompt with Admin Rights. ##
## > list disk ##
## >.... ##
## > select disk 1 * Note: disk nbr is the nbr of the USB disk ##
## > clean ##
## > create partition primary ##
## > exit
