I have downloaded and burned Suse 9.2 Live CD (Gnome version). The problem is, it won't boot. MD5 checksum is correct. I get "searching for boot record on CDROM... not found" message and then system just boots from hard drive. Recently I used the very same CD-RW as bootable CD and it worked.

Is there a way to make the CD boot, maybe using a floppy with some bootlader (syslinux, grub?) as an intermediary?

This is almost certainly a media compatibility or hardware issue.

Maybe, but this kind of error could also show up if the iso-image file was burnt as an ordinary file instead as an iso-image.

Hmmm. I thought data CDs required an iso file system. I've always either used K3B or used mkisofs to prepare an iso image for cdrecord to use. Interesting. Is the burnt file usable? Say I was to burn a large log file to a disk, can I then mount the disk and read the file? Jeff Jeff

Suppose you have a directory called 'test-dir', containing 1 file called 'README':

mkisofs -o test-dir.iso test-dir

Now you can mount the file 'test-dir.iso':

mkdir mnt mount -o loop test-dir.iso mnt ls mnt . .. readme umount -d test-dir

If you burn test-dir.iso as an ordinary file, and you mount the CD to e.g. /media/cdrom, then:

ls /media/cdrom . .. test-dir.iso

And:

mkdir /tmp/mnt mount -o loop /media/cdrom/test-dir.iso /tmp/mnt ls /tmp/mnt . .. readme

If you burn test-dir.iso as an iso-image, and you mount the CD to e.g. /media/cdrom, then:

ls /media/cdrom . .. readme

Good explanation. Thanks Leen Jeff

Hello,

I have downloaded and burned Suse 9.2 Live CD (Gnome version). The problem is, it won't boot. MD5 checksum is correct. I get "searching for boot record on CDROM... not found" message and then system just boots from hard drive. Recently I used the very same CD-RW as bootable CD and it worked.

This is almost certainly a media compatibility or hardware issue. Many CD-ROMs have problems booting off of burned disks and some older CD-ROMs just don't boot at all. Try burning the disk at a slower speed or on different (higher quality?) media. IIRC the floppy boot images are on the disk so you should be able to make boot floppies if you need to.

That might be. When I burned the 9.1-Live cd I had to include a boot image along with the ISO for 9.1. I ended up with one non-bootable and one bootable CD, I was using xcdroast.

As a followup to this, I did burn the 9.2 as the only .ISO and it booted up fine. It hung on the pcmcia detect (Dell Latitude D600 with Linksys 2.4 ghz wireless card inserted,) when i rebooted the system after removing the wireless card, it booted but didn't do a great job detecting and auto-setting the display.

I've had this problem on an old laptop a few years ago, it turned out to be that it objected to the CD-RW on which it was burned, I found I had to use CD-R's, it just couldn't handle rewriteables, so now I burn anything bootable on CD-R and use CD-RW for anything that doesn't need to be bootable. Regards

FWIW, I made two coasters before I got smart and used a real good 700 meg blank, NOT a RW, and recorded it at 2x, just to be sure. It booted and ran fine where the others wouldn't. RA -- Old age ain't for Sissies!

Thanks for all replies. Here's some more info:

* I'm running Windows 2000, Nero 5.5.9.13 * Hardware is LiteOn 52/32/52 * I have burned ISO images before using Nero's File -> Burn Image... command * Recently I burned bootable Plan9 disk using the very same CD-RW and hardware, worked * I tried to burn Suse Live CD twice, using the same disk * The disk is Verbatim CD-RW 4x

I've had good luck with Verbatim disks and they should be a good quality. Sid makes a good point. Try burning on a CD-R at 2X and see if that makes a difference. Jeff

I didn't want to use a CD-R because live cd is by its very nature a throwaway disc. But I got lured into believing that a plain CD-R (very good Philips... at 40x. sigh...) will boot. F#$%! It won't. Still "searching for boot record from cdrom... not found". I am pissed off. Is it that difficult to burn a working bootable cd from a f#$%ing image?

I don't know how things are in Poland, but in Canada, you can buy (in bulk) 4 or 5 CD-Rs, for about the price of a cup of coffee or a loaf of bread. They are disposable.

Did I understand you to say you were using Nemo??? to burn the thing? Isn't that a windows program???? try Downloading the kde version and burn that and see if it has the same problems... I don't recall seeing a Gnome version, but it could just be I wasn't looking for one. -- j -- nemo me impune lacessit
