[NEWBIE] Iso not Bootable?

Pure.Krome · n00b Joined: 19 May 2002 Posts: 3

Hi Folks.

i've just downloaded gentoo-i686-1.1a.iso

I've burned it onto CD, disk-at-once.

But when i try to boot it, it fails (ie. cannot find any boot device).

I've set up my bios to boot from CD ROM first. Other CD's boot fine, just not my burn.

Is there some ~special trick~ to burn the ISO onto CD, to make it bootable?

Thank in advance to any help.

i've had the same problem. i checked my iso with md5sums, and like his, i can mount and read the cd. i burned mine with linux, using cdrecord. i have an adaptec 2940 card and HP9200 CD. no boot, although i boot redhat, freeBSD, and the cvarious winblows just fine from CD.

I also have the same problem.
The I686 ISO CD wont boot but, my FreeBSD Cd will.
I've used Nero to burn the CD, but i couldnt tell you the settings atm.

I have the same problem. Gateway 935c rackmount p3 1.3Ghz. I have booted Win98 and Mandrake from the box, so the bios is set properly. The gateway sets up the ide cdrom as the master on the secondary ide channel on the first ide controller. Anyhow, when the iso boots, it says operating system not found.
I burned the cd w/ x-cd-roast .98alpha9. That uses cdrecord as it's backend. The options I chose were Track at Once TAO, Disk at Once, DAO, and also chose 1x write speed. I don't think it's that because the 16MB buffer never goes under 99% full even at 12x write. I also verfied the cd can be read on other systems with 3 .tbz files, and a isolinux directory. It won't boot on another machine I have here either. Don't know whether it's the burning software or the .iso image. I think I have 1.1a.iso.
I'm not ready to buy a cd, that would take days to get here. I think I will go to the chinagnu smart boot loader and give that a shot.

I had a similar problem with my Gentoo 1.1a ISO on a Winchip2A-200. The CD wasn't at fault, as I could boot the CD from a different PC, and the PC would boot from other CDs. I fixed it by updating the BIOS. It's a shot in the dark and it's probably totally irrelevant, but if it was that then it wouldn't matter how the BIOS was set up.

Just a thought.

Here is an update on the Gateway 935c. First, the 935c is the machine I am trying to boot. The machine that the cd is written on is a custom abit-kt7-raid based system w/ scsi and a hp 9600 internal cd writer write12x.

Second, I downloaded Smart Boot Manager, and tried to boot from the CD (by the way I have made 4 so far), it said OS not found! I tried to boot a win98 CD in the same session from Smart Boot Manager, and it launched.

Inside of X-CD-Roast98alpha9, I did a verify between the .iso and the cdrom. It says 'failed: short read at 137xxxxxx' something. What that's telling me is something isn't burning right on the cd. I wish I could figure it out.

I had the same problem, it turned out to be the cdrom player. Gentoo uses a system known as isolinux to create a boot cd. Only newer types of cdrom players support this. I temporarely swapped cdrom player just to install and after that reinstalled the original cdrom player.
