You will know because when you mount the sdc1 partition there should be a folder EFI on the root of the partition. The sdc1 partition MUST be fat32. Using a linux partition won't work if you are trying to boot via UEFI.

Then please try this.

root@porteus:/home/guest# cd /mnt
root@porteus:/mnt# ls
live/ sda1/ sda2/ sda4/ sda6/ sda7/ sdb1/ sdc1/ sdc3/
root@porteus:/mnt# mkdir sdc1
root@porteus:/mnt# mount /dev/sdc1 /mnt/sdc1
root@porteus:/mnt# cd /mnt/sdc1/boot <----- make sure you go exactly here
root@porteus:/mnt/porteus-boot# ./Porteus-installer-for-Linux.com

Once you get this working we can work on using a second linux partition on which you save your changes. A FAT32 partition is only needed to get the UEFI booted.

thank you brokenman for clearing this up with UEFI, also i just found out, there is a "secure boot" feature that has to be turned off as well, bcz it wint "authorize" usb boot
so i used universal usb installer from pendrivelinux to install porteus on fat32,
now i have it working in 'always fresh' mode

Using windows filesystem with linux OS is not the best idea. Do you use windows with a linux filesystem? You would be better proceeding as proposed by brokenman.

However, the save.dat container for fat32 file system. It is a little more complicated to work with. See:

ok, so im trying to install Porteus on USB drive. no windows on this drive whatsoever. originally i wanted to install everything on ext4, but bcz i have this UEFI bios, that wouldnt allow boot with linux partition,(as brokenman adviced, i install Porteus on fat32, to bypass UEFI and boot, after that i have another Linux ext4 partition for saving changes.

so , i created save.dat file in /mnt/sdc1(name of my ext4 partition), and added cheatcode changes=/mnt/sdc1/save.dat to APPEND line in porteus.cfg file, in the paragraph, where it says about Graphic mode,
also im not sure if there is an actual path to the save.dat file, or it suppose to be as shown changes=/porteus/save.dat

so when booting, system cannot find this save.dat file, and booting in 'always fresh mode'

this is why i wanted to go with linux FS only, but turns out, my laptop has UEFI bios , that wouldnt boot with it, so i did, as brokenman adviced, devided USB on 3 partitions, 2gb for OS fat32, 20gb ext4 for changes, and 3gb for linux swap

its just i installed it differently, using universal usb installer GUI

And how are you doing with the save.dat save file?

The save.dat file is designed for non-Linux file systems so I'm not sure it works on a Linux file system. The changes= cheatcode points to the save.dat file on the boot device and does not need the /mnt/sdxy/ path specified.

Try moving your save.dat file to the FAT partition's root and changing the cheatcode to changes=/save.dat and see if that helps.

So the first partition on the device needs to be FAT32. Make it however big you like. Mine is 300Mb. On this partition you need to put the EFI folder from the Porteus ISO.
One the second partition (ext4) you can put the porteus folder.

Now go into the refind.conf file which is located in the EFI/BOOT folder and make some changes. The main changes you will need are the from= part. You can get the UUID from a root console by typing: blkid
For the changes you can also use the UUID. Something like: changes=UUID:d2c78202-d77d-4fea-a793-e3758ed1b438/changes

menuentry "Porteus GUI mode" {
volume KERNELS
icon EFI/BOOT/icons/os_porteus.png
loader boot/syslinux/vmlinuz
initrd boot/syslinux/initrd.xz
options "from=UUID:d2c78202-d77d-4fea-a793-e3758ed1b438"
submenuentry "Save changes" {
add_options "changes=/porteus"
}
submenuentry "Always fresh" {
add_options "nomagic base_only norootcopy"
}
submenuentry "Boot to copy2ram mode" {
add_options "copy2ram"
}
submenuentry "Text mode" {
add_options "3"
}
submenuentry "pxe-boot" {
add_options "pxe"
}
}

Let us know how it goes.

@zander

There is a sample USB that has two partitions,
the 1st one is a fat for EFI boot
and
the 2nd one is ext4 for a container of persistence dat.


The sample may be useful for your case;

1. make a persistent dat (Example: persistent data size was set to 200M)
[ From Terminal ]

Code: Select all

# mount /dev/sdb2 /mnt/sdb2
# cd /mnt/sdb2
# ls
lost+found/
# mkdir persistent
# cd persistent
# dd of=porteus.persist count=0 seek=200000000
# mkfs.ext4 porteus.persist
2. edit grub.cfg
menuentry "persistent mode" {
search --set -f /boot/syslinux/vmlinuz
linux /boot/syslinux/vmlinuz changes=/persistent/porteus.persist
initrd /boot/syslinux/initrd.xz
}
menuentry "ram mode" {
search --set -f /boot/syslinux/vmlinuz
linux /boot/syslinux/vmlinuz copy2ram changes=EXIT:/persistent/porteus.persist
initrd /boot/syslinux/initrd.xz
}

Good luck!

You just care about the uuid after the from cheat code and put in there the one from your ext4 partition in which there should be the /porteus and /boot folders. Do not care for the save folder, under Linux file system, that is your ext4 partition, it will be set automatically.
