Having trouble with .ISO images

Link to this post 31 May 10

Greetings all,

I have used Unetbootin and universal usb installer to make a bootable flash. I get around 51 errors with both programs. They successfully install the Ubuntu stuff on the flash, but it will not work upon boot up. I have an Acer net book, and I have updated my BIOS. My only guess is that I somehow got a bad .ISO image. Thus the errors in both flash boot programs. How does this occur and how can I get an ISO image without errors. I have already downloaded the ISO multiple times to correct the issue, but it still refuses to work. Could it be another issue?

Thank you in advance

Andy

It's a holiday weekend, so I don't know if too many folks will be around today. I use Fedora (apps are very similar to Ubuntu since they both use Gnome desktop). I do believe Ubuntu comes with a Live USB installer, maybe someone here will take pity on us and come up with the apps name. It might be "liveusb-creator", since that is what the Fedora manual points to. I'll give you 3 links to look at. The first is the liveusb-creator site, the second is the instructions from the fedora manual and the third is an alternative site I keep linked because it was useful in the past. Read them over and maybe you can find a solution to your problem. And hopefully, some other suggestions may come in on how to work around your problem. I don't think you getting repeatedly bad iso's, it's probably the way your laptop handles boot from a usb stick, or the way the stick was created. Maybe looking over the instructions on the sites below may help you work out what's going wrong.

I have seen this issue before from the ubuntu liveusb-creator. It may be the way that the application is handling the iso file or that some files it needs are no in the iso. Can you please post your error messages from the usb image creation process in here?

The program won't allow me to copy and paste the error messages. I will work on writing them down and transferring them.

I tried the fedora live usb creator. I still get errors. It boots to a system message and flashes errors and then to a blank screen.
