Can't Install Slackware 12 - Disk Error 32


Hello Everyone,

I downloaded the DVD install ISO and attempted to install Slackware 12. It reads the DVD, but as soon as the "ISO Linux....." is displayed, it halts immediately with the message that boot failed with "Disk Error 32". I assumed I had a bad burn, so I downloaded again from a different mirror, and burned to a new DVD. Same result.

I have googled Disk Error 32 and didn't find anything on the LQ forums.

Anyone have any experience with this error report or know why it occurs?

I have not tried to boot from a floppy yet (though I have read this is possible.) I wanted to figure this out first. Not a hardware failure as this disk works will with other distros.

Any help greatly appreciated.

Bob

Did you run a checksum against the iso. Try burning a 4x or lower.

Thank you for your help. I have read the link you provided, but have never tried to deal with mkiso commands. Unfortunately, when I try to open the isolinux folder on the DVD, I get "UNABLE TO OPEN README.TXT" in gedit, or any other editor I tried. Again thought it was a bad burn so I tried it again, same result.

How do I create this bootable iso disk as described?

Any help appreciated. Never have experienced this with Slack before, 10.1 installed seamlessly on this same machine.

This is a brief example -

You need to mount your downloaded iso image.

mount -o loop -t iso9660 <slack12iso>.iso /mnt/<mountpoint>

enter your mounted iso.
cd /mnt/<mountpoint>


Create new ISO
mkisofs -o /tmp/slackware-dvd.iso \
-R -J -A "Slackware Install" \
-hide-rr-moved \
-v -d -N \
-no-emul-boot -boot-load-size 4 -boot-info-table \
-sort isolinux/iso.sort \
-b isolinux/isolinux.bin \
-c isolinux/isolinux.boot \
-V "SlackDVD" .

Your new dvd iso should be located in /tmp dir
burn it and try it.

again this is only an example...

If your downloaded iso md5 is not good then doing a mkisofs will not work for you. You need to find out if the md5 is bad.

I would check the md5sum. Since you downloaded the cd/dvd iso then be sure to check the md5sum for the original iso. From the cli;

Code:
~#cd /downloadisolocation      #cdromiso.iso cdromiso.md5 

~#md5sum -c cdromiso.md5       #substitute the correct name to check
If the iso md5 is ok then you should try 'CdromMd5sumsAfterBurning''.

This way you will know if the burn was OK!

This will check the download iso with the known md5sum that you also get with the iso.

You could do a ftp install using the 'lmo-install-0.2.iso', it took about 2 hours for me on DSL for Slackware 12.

These links and others can be found at 'Slackware-Links' .

Thank you ArcLinux, excellent, clear instructions. I will try this tomorrow. One question, though. The instructions for Slack 12 on the link you provided indicated I should make the boot-load-size 32. Is 4 correct, or should this number be 32?

Thanks again for your help.

Bob

Thank you, oncebuck. I would prefer to do an online install if possible. Did that a few years ago with Debian and it worked great. I have been away from Linux for about two years until a month ago (and computers for that matter.) I seem to have forgotten more than I thought. The burner (K3b) checked the MD5 sum, I had never had a MD5 problem before. I will follow your instructions and check this.

Hopefully, one of these methods will get Slack installed. I have kept a partition open for Slack 12. I do remember that when I was learning the most about Linux, it was when I was using Slack 10.

Thanks again.

Bob

I don't rely on a application like K3B to confirm the md5. I also like to check the burnt cd/dvd iso with the original md5 to confirm the burn is good.

The lmo-installer-0.2.iso is a good alternative if you have the bandwidth.

Good luck!

UPDATE: Slack 12 just doesn't like this machine.

Fascinating. I have tried all of the suggestions in this thread to no avail (except for the net install, which I am not sure how to do.) I just keep getting the same error messages. However, I did try to boot these DVDs in other machines, and they work just fine. So, I have determined my problem is not with the DVDs I downloaded, or the MD5 sums. The odd thing to me is that I have three other distros installed on this same machine (along with windows) and have not had any issue with any of the install DVDs for the other distros.

I formerly had Slack 10.1 on this same hardrive before blowing the motherboard. I replaced the motherboard with the same brand (Gigabyte), same bios (Award), but the new board has a different chipset (VIA as opposed to nVidia on the blown board.) I can't imagine this having anything to do with not being able to boot from the Slack 12 DVD. I have the drive set up as follows:

sda1 - Windows XP
Sda2 - PClinuxOS
sda3 - Fedora 8
sda5 - Unallocated (waiting for Slack 12)
IDE hd0 - Ubuntu

The out-of-sequence numbering is due to creating deleting partitions with Gparted, but I don't believe this will create any problem as long as the grub entry points to the right partition.

The last DVDs I downloaded was from the official Slack site, and as I indicated, MD5 sums ok, and it booted fine in another machine.

It is interesting that another thread about non-bootable Slack cds/dvds has received quite a bit of attention, though that thread discusses the Dell machine exclusively, but the problem sounds very similar to this one.

I will try one more time and possibly learn to do the net install from one of the other distros on this machine. But it is looking like I might have to give up on Slack 12 and just wait for the next edition, or re-install Slack 10.1 and try to use a newer kernel. I am trying re-learn linux after a lengthy absence from it, and I was counting on Slack catching me back up on what I had forgotten, so this is certainly disappointing. Failing any of this, my choice would have been Arch or Debian.

Thanks for any thoughts or replies.

Bob

Hi,

The load problem at boot could be because of a broken BIOS. The 'boot-load-size 32' for Slackware 12 has given several people problems with older/broken BIOS when the change was made from 4 to 32. The increase was made to allow a faster boot and compatibility with newer BIOS.

'Cant install Slackware 11 on dell dimension 4100 creepy!' is a good thread to look at.

Same thing happened to me recently. The partition numbering order got jumbled. Things still function, but little things like that jumble my mind too. There is a straightforward remedy to restore the order of the partition numbering:

1. As root, at a command line, type fdisk /dev/hda (change hda to hdb, sda, etc., as necessary for your system).

2. At the fdisk command line, type x. This opens the extra functionality menu.

3. At the fdisk command line, type f.

4. At the fdisk command line, type w to write (update) the partition table information.

Be forewarned that you might need to edit fstab and your bootloader menu before rebooting.
