Porteus

hello
im new here, just installed porteus 3.1 to usb, through GUI 'install porteus' from another porteus USB drive, which i installed with UUI from windows.
so USB is partitioned in two: ext4(flagged bootable), and SWAP. mounting ext4, and marked it with bootloader install,

after successful install, reboot starts windows, not usb. ( i modified win BIOS to boot from usb, its working with other flash drive)
please help
what could go wrong
thnx

Hello zander
Sometimes it doesn't work when the target thumbdrive is mounted at /run/media/somewhat.
mount it at e.g. /mnt/sdXN, cd into /mnt/sdXN/boot and run the "installer for linux.com"

wish i knew how to follow )((:
can u give step by step how make it happened? (how can i mount it during boot , if all i see is windows boot??)
also linux.com installe? do i have to reinstall something?
thnx

boot the other porteus thumbdrive, mount the target thumbdrive at
/mnt/sdXN
(sdXN = X = device (a,b,c etc.), N = partition number (sdb1 for example)

(to make it easier, log in as root for this task)
you have to create that folder first.If you don't know your target drive/partion
name, open a terminal type su, Pw is toor and then type fdisk -l (lowercase L)

mount the target drive at that folder, go into this folder, there should be a
porteus and a boot folder, go into boot and execute the "Installer for linux.com"
please doublecheck that you install the bootloader to the right device.

thnx for yr help!
not clear what folder do i have to create, is it /mnt/sdNX? fdisk gave me name : sdc1
so when : mount /mnt/sdc1, it was already there : /mnt/sdc1, ?
how can icheck where bootlodader installed?
anyway, i did this : sh /mnt/sdc1/boot/Porteus-installer-for-Linux.com
let see what happenes on reboot

so after reboot i got windows again, ... (

hi try to use the porteus that work for you,after you have boot the porteus system plug in the usb that not work open console and type fdisk -l you have a list of the devices, you have to mount the device manually with mount /dev/sdx1 /mnt/a directory you choose,after this you can run the linux installer script inside the mounted directory, look if the installer choose the right device,

Hmmm....
--> i modified win BIOS to boot from usb <--
what does this mean?
Q:Is this Pc using UEFI or normal / legacy bios?
Is it possible to check if this thumb drive will boot a different PC?

hi maybe have the F11 or other F key to choose the boot device......

Is it possible to check if this thumb drive will boot a different PC?

yes this is UEFI BIOS, on HP envy, m6
so it means that i changed the boot priority
not really possible to check other PC, im on MAC

hi have you read this tread viewtopic.php?f=81&t=3556

To apply Donald solution, you need to proceed from a Linux installation. And your bios has to be set to USB first.

well yes im sure , becz it works with other porteus USB that i created from windows, which is totally bootable. im just trying to install porteus on linux partition,

Be sure you download the LATEST Porteus from build.porteus.org and be sure to include the UEFI option. 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.
