[arch-general] ISO broken? Unable to boot from ISO burned to DVD.
Hello, I've freshly downloaded the ISO from the Arch Linux homepage and burned with: # cdrecord dev=/dev/cdrom -dao PATH_TO_ISO Booting from this hangs with waiting for some /dev/disk/by-label/ARCH... device. After waiting for this I get to some kind of "recovery console" missing most tools. /dev/disk/by-label doesn't exist at all in this minimalistic shell. Is it possible that booting from a device "by-label" just doesn't work for a DVD drive at all? Any way to fix this? Thanks in advance Manuel

Ran into this same problem for the first time in September, just follow the directions and write the .iso to a USB stick and it should boot fine. There is an entire forum thread devoted to this issue. You can read all about the latest theories as to why it happens, there. But regardless, the easiest solution is simply to install from a USB. -- David C. Rankin, J.D.,P.E.
This issue is weird since I installed Arch 3 days ago without any problems during boot. Maybe it would be good to try it without -dao ? -- *Jean-Philippe Provost* 2016-11-15 1:45 GMT-05:00 David C. Rankin <drankinatty@suddenlinkmail.com>:

The problem seems atavistic, the last thread I read on it was: https://bbs.archlinux.org/viewtopic.php?id=195763 where, if I recall correctly, there were no fewer that 4 different theories discussed as to the cause of the CD/DVD failing to show up. I've only had this occur once, on a SuperMicro box, but burn to USB installed without a problem. -- David C. Rankin, J.D.,P.E.

Maybe if you try -sao -speed=8 without -dao. Maybe you need slower burn. By default, if you don't set speed, drive will use the maximum one.

Hi,** *From man cdrecord, I found* : -sao Set SAO (Session At Once) mode which is usually called Disk At Once mode. This currently only works with MMC drives that support Session At Once mode. Note that cdrecord needs to know the size of each track in advance for this mode (see the mkisofs -print-size option and the EXAMPLES section for more information). Which I think won't change anything from -dao to -sao. Have you check the signature of the ISO file (md5) ? Maybe it's just corrupted? Does your cd recorder supports Session At Once (-sao) ?
