Error launching USB install

[cm1967]

Hello all,

I'm having an issue installing Salix 14.2 from USB. When I boot the install, I receive the following error message:

Unregistered Exception Handler

I've used both dd if=image.iso of=/dev/sdb bs=4M and dd if=your-salix-iso-image.iso of=/dev/sdb to "burn" the ISO to USB but neither is working. When installing Debian or Fedora, I don't receive this error. Just happens with the newly released Salix 14.2 and Salix Mate 14.1.

Just can't quite figure this one out.

Thanks!

Are you perhaps trying to run a 64bit iso on a 32bit PC? Or maybe a 32bit iso on a UEFI 64bit system?

64 bit version of Salix on a ThinkPad T400 (non-UEFI 64bit machine).

Can you try with another USB stick?

Thanks, again, for the reply. I tried multiple sticks, with one being brand new. I'm going to try using unetbootin to see if that works better. I'll update the post with my findings.

Thanks!

Did you check the integrity of the ISO you downloaded with md5sum? The checksums are here:

What, exactly, goes wrong? Does the dd command complete? What happens when you attempt to boot the USB?

I'm not sure whether Unetbootin works for Salix at the moment. But the copy-to-USB method definitely should.

Sorry if this is a silly question, but you do realise you need to replace the path in that command with the path to the iso image as you downloaded it, and with the correct device (for the USB)?

So for example, if it is in Downloads, and the image is called salix.iso (which it isn't) and you are in your home directory, and the stick is seen as /dev/sdc (which it probably isn't) you would need to type

Code: Select all

dd if=Downloads/salix.iso of=/dev/sdc  

To check the device, do

Code: Select all

lsblk

without having inserted the stick; insert the stick and do it again. If I do this i see, first time:

Code: Select all

[code]mimosa[~]$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0  29.8G  0 disk 
├─sda1   8:1    0  10.6G  0 part /
└─sda3   8:3    0  18.8G  0 part /home

[/code]
Second time:

Code: Select all

mimosa[~]$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0  29.8G  0 disk 
├─sda1   8:1    0  10.6G  0 part /
└─sda3   8:3    0  18.8G  0 part /home
sdb      8:16   0 931.5G  0 disk 
├─sdb1   8:17   0 402.4G  0 part 
└─sdb2   8:18   0   529G  0 part 

That isn't a USB stick, it's an external hard drive, containing two partitions. But the point is, you can clearly see the device name your newly inserted device has been allocated, and that is the one you want to use for the dd command. Note that if there is an existing partition (e.g. sdb1) you don't want to write to that, you want the device, which in this case is /dev/sdb.

EDIT root privileges shouldn't be needed to write to a USB, corrected accordingly - thanks for pointing that out laprjns!

Sorry for taking so long to respond.

To date, I have tried multiple USB sticks, 3 being brand new and the other 2 freshly formatted. When I use dd and unetbootin, they all complete and I'm able to see the contents of the USB stick. I have checked the integrity of the md5sum each time I downloaded the ISO and it is fine. The error occurs when I boot the USB stick. I'm now finding that this is only happening with the latest release, 14.2 Xfce. The 14.1 Mate is working fine. I'm able to create the USB stick, boot from it, and then finish the install. I'm typing this from 14.1 Mate.

Thanks, again, for all the ideas.

Just a quick update if anyone is interested:

Not sure why I didn't think to try this before, but I downloaded, booted, and successfully installed the SalixLive 14.2 release. I still can't figure out why I'm having issues with the non-live release of 14.2.

More often than not this is a BIOS (EPROM) issue.
