iso update

[dartex]

computer 1 - siduction 2013 updated
window appear, I choose sdb, persist, iso image (sid 13-kde and 14-lxqt), and then errors.
"grub-install failed, root-directory=/tmp/install.usb.xxxxx, device /dev/sdb STOP"

computer 2 - siduction 2014
I choose sdb, persist, iso image, it seems to start, a terminal requires root password, after a few seconds "grub-install failed, root-directory=/tmp/install.usb.xxxxx, device /dev/sdb STOP".
and in the stick there is now a folder "/boot/grub".



edit:
with pc 2 it starts, this is the message:

Strange,
I now created an ext2-partition on an 8GB-SDcard via gparted and installed onto it.
It went completely trough without any problems. I could also boot from this card.

Could it be that the partition table on your device is broken?

Installation was done from an running Siduction 64-Bit system and used the latest 2013 64Bit XFce Release as installation image.

I also remember that there were times with some usb-sticks, but that is quite a while ago.
Anyway do you have another stick wich you could try ?

I created a new (msdos) partition table, with new ext2 partition (4gb).
I can write on it, and it start to write (installing grub - is it normal it install "for i386-pc platform"?).
I'm running 64bit and iso is also 64bit...

No, I don't have another stick.

"for i386-pc platform" seems to be normal, the same here.

I was picking on the partition table and the stick because of those strange messages:

4GB should normally be sufficient but i am not quite sure on the persist option. But you already tried it without it as I remember.

Maybe an complete erase of the stick via dd (dd /dev/sdx if=/dev/zero of=/dev/sdX) might help.
But be carefull on the sdX ! Make sure that you have the right device named or your system or data will be gone really fast !

After that you can use gparted to create the partition table and the ext2 partition and give the installation another try.

ok, I'll try.

the command is dd /dev/sdx if=/dev/zero of=/dev/sdX?
or dd if=/dev/zero of=/dev/sdX?

[der_bud]

The second one, well seen that there accidently is a '/dev/sdx' to much in the given command above.

[ReinerS]

Ooops. sorry, my fault

I guess in your case it might be /dev/sdb as this was in some of your posts.

Good idea to always check you have the correct device ID before running dd on it. You can do this by running, immediately after plugging it in -

dmesg |tail

[dartex]

ok, I formatted the key but it doesn't work!

I tryed with an another key and it did work!
so... I really don't know why it doesn't like the first usb key...! 

but "persist" option seems is not working, I always lost changes...
do I have to add something at the boot?

[piper]

Have you read

fromiso-persist

[dartex]

Have you read

fromiso-persist

thank you!
I forgot the other usb key was fat32... 
I will try again, I created a file-rw but for the moment I could not boot with it...
