How to install Linux from an iso disk.
 

I can't boot to the iso ubunto disk I have. How do I do it!
I'm new to Linux, but have considerable computer knowledge. I have built several computers. Thanks for your assistance.

Does your BIOS supports booting from CD?
Did you burn the ISO correctly to the CD?
Do you get some errormessages?

Hello and welcome to LQ!

My bios does boot from cd. It will boot to a windows disk, but I don't want windows anymore. I have tried two different disks I have but didn't make myself. How can I check them?? I don't get error messages, the disks just aren't recognized. thanks for reply

Maybe the disks weren't closed properly, try burning an ISO yourself.

Hi,

In my case I once had a case where, the CD tries to boot but gets stalled while trying to "load" the kernel --- just hanging forever. I later realized that I was trying to boot a relatively old kernel with a relatively too new dual processor PC. A colleague, who happens to be a linux guru, told me that it was a chipset issue, so I download one of the latest releases at the time. I cannot actually give at this stage the kernel number that was failing, nor can I furnish the chipset detail I had.

I suggest that you give the full specs of the PC, as well as more detail about the linux CD you have --- perhaps someone knowledgeable may then see what your problem could be.

Cheers,
Isix

Also make sure the .iso was burnt to the CD as an image, not copied as a file. If you look at the contents of the CD and it says something.iso then they just copied it as a file. That that file and burn it to a CD as an image. Most CD burners have that as an option.

That is an option I recently learnt about from this forum.

Hi,
Welcome to LQ!

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

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. If you do fail the md5 checks then you could slow down the burn of the iso image to see if that will work for you.
