[SOLVED] Can't burn iso on dvd

SlackQc · 03-23-2020, 10:11 AM

Hello, yesterday I tried to burn an iso image of Devuan on a DVD with xfburn, the dvd contains some files but does not work when I boot, I also try with uNetbootin and I have the same problem. On the screenshot, are the files installed by uNetbootin. I also try on the command line but it doesn't work either

Please define "does not work when I boot".

What does happen when you restart? Do you see the boot loader or it doesn't get that far? Have your BIOS options been appropriately changed to support it? What settings were used on unetbootin?

To define "does not work when i boot", with my usb key, I have the uNetbootin menu, but only with the Default choice, otherwise with the xfburn dvd, nothing happens and it boots from the hard disk.

For uNetbootin options, I don't change anything.

When I installed Slackware last November, I made my usb stick with uNetbootin on windows 7, without modifying the options.

From a linux system just use the dd command. You do need to run the command as root.

dd if=devuan.iso of=/dev/sdxy

Replace with the actual file name and device ID of your USB flash drive. As a caution there is no safety net using this command. Make sure you use the correct device ID of the usb drive since this will easily overwrite a running system and recovery without a backup is not easy.

Also no need to use dd and its exotic syntax, cp will do the job as well.

this is the first method I tried, and it doesn't work.

What ISO file did you download?

I would like to add that the BIOS is not the problem, I am able to boot on a disk that I made last year, Manjaro Linux and Xubuntu.

Did you check sha256 sum to verify a good download?

I can not confirm that unetbootin is compatible with devuan and would not know why dd would fail except for maybe a bad download.

SlackQc · 03-23-2020, 12:50 PM

SHA256sum is ok, the iso file should not be corrupted, and no, uNetbootin does not support Devuan, it is for this reason that I install xfburn

michaelk · 03-23-2020, 12:57 PM

I can boot the ISO file using VirtualBox so in theory xfburn should be able to burn image to CD/DVD and boot successfully. Make sure you select burn image.

Why not using growisofs?

From /isolinux/README.TXT

example:

Code:

growisofs -speed=2 -dvd-compat -Z /dev/sr0=slackware-dvd.iso

If your burner is not /dev/sr0, replace the device with the one your
system uses.

So now I succeeded, I re-download the same iso image and burn a DVD with xfburn. I don't understand why it didn't work, however I did check the sha256sum signature. By cons, impossible with a usb key, I try with 3 key and it does not work! I will try to find the problem because yes, there is one.

Thank you for your time!

Hello,

I just tried it.
I had to build unetbootin and 7Zip from SlackBuilds.
I downloaded the same ISO, burn it on USB stick and my laptop is now running Devuan.

Slackware64 14.2 multilibs
kernel 4.20.11.

The usb stick was formated with

Code:

mkfs.fat /dev/sde1

Good point, unetbootin uses isolinux which requires a VFAT partition. However, it does not matter with the dd command and that would be my preference.
