Using install dual iso 2012-09-07 - graphics issue? [SOLVED]

mcloaked · 2012-09-15 19:50:19

I have made a bootable usbkey with the archlinux-2012.09.07-dual.iso
file but having tried to boot it, both on an Inspiron 530s and also a
Samsung Q35 netbook, there is a blue "graphics" screen but it does not
stop and offer me the choice of i686 or x86_64 but carries straight on
to boot to the normal prompt. So I can't choose which architecture to
use for the install.

Does anyone know a workaround to be able to get to choose which of 32
or 64 bit to boot for the install? Or is there a problem with this new
install media on some hardware?

I have done quit a bit of reading but not seen this issue mentioned in
any of the arch wiki or other google searches.

Thanks

The fact that the usb stick doesn't work on two different machines is interesting, and make me think it's more a problem with the usb stick than with your hardware. Did you check the md5 or sha1 checksums after you downloaded the iso? How did you copy it to the usb stick? Can you try copying it again?

Which method/software did you use to prepare the USB stick?

Yes I checked the sha1sum after download.

I used unetbootin - which I have used many times to prepare things like PartedMagic for example. The unetbootin run seemed to prepare the isbkey without issue.

I have been told on the arch general list that unetbootin breaks the image! As it is late here I will try to the dd method tomorrow and see if that works - and report back once I have tried that.

EDIT: Too late

This shouldn't be possible unless the iso, usb-stick or written data has been flawed in some way during processing...

There's zero reason to use unetbootin for things like these; use dd to write the iso to usb and check both the iso and the written data to the usb-stick afterwards.

I've made a shell-function which I use, that automates the above and which you're free to use also:

Usage:

$ iso2usb <file> <drive>

iso2usb() {
	md2=$(md5sum $1 | cut -d " " -f 1)
	sudo dd if=$1 of=$2 2>/dev/null
	md1=$(sudo dd if=$2 count=$(( $(stat -c %s $1) / 512 )) 2>/dev/null | md5sum | cut -d " " -f 1)
	if [ $md1 != $md2 ] ;then
		echo FAILED!
	else
		echo OK!
	fi
}

OK I tried with the dd method and it works perfectly... I will check back on the wiki and edit to ensure that a comment is included that the unetbootin method does not work.

Thank you for the shell function - which I will use though I changed it so that the drive only needs defining as an argument as "sdX" and added in the /dev/ prefix in the function as per:

iso2usb() {
        md2=$(md5sum $1 | cut -d " " -f 1)
        sudo dd if=$1 of=/dev/$2 2>/dev/null
        md1=$(sudo dd if=/dev/$2 count=$(( $(stat -c %s $1) / 512 )) 2>/dev/null | md5sum | cut -d " " -f 1)
        if [ $md1 != $md2 ] ;then
                echo FAILED!
        else
                echo OK!
        fi
}

Thank you for the help.

I have edited the wiki at https://wiki.archlinux.org/index.php/US … UNetbootin to include a warning about unetbootin for the dual architecture install isos.

Fucking Unetbootin... It was removed at least three times already from the wiki. It's a piece of shit.

It's way too intrusive. It installs its own version of the bootloader, a crappy syslinux.cfg, and doesn't give a shit about labels.

Unetbootin is totally NOT recommended for Arch Linux and it should be removed from the wiki.

Use something else.

Just out of interest, is there a recommended method for use on a Windows machine?

anonymous_user · 2012-09-16 23:04:26

I don't know about recommended however I just tested Win32 Disk Image aka Image Writer for Windows:

https://launchpad.net/win32-image-writer

And it handles the Arch Linux ISO with no issues (that I've noticed anyways).

If you prefer the commandline, try dd for windows or windd
