ISO installation

teamstatic84 · 07-19-2003, 07:45 PM

My ISO CDs are not booting from the CDROM drive. I have Redhat 6.1 running on my 586 computer and wanted to switch up to my Redhat 9 OS. I burned my ISOs from the Bit Torrent software onto CD-Rs, and when I try to boot with them, the computer ignores them. The thing is, my Redhat 6.1 CD which is an official Redhat one boots from the CDROM just fine. I tried making a boot disk on a floppy, but the computer didn't even check the floppy drive during startup. Can anyone give me an idea? (Don't ask me about checksums)

setup your boot sequence in the BIOS to boot to floppy first.

But why is it booting from the CDROM with the 6.1 version? Is it not happy to boot a CD-R?

depends on your cdrom....if it is an older cdrom, then yes that is probably the problem.

Thanks Drozz, I'll try that. You'd be a real friend... if I liked you.

I've modified the BIOS configuration to boot from the floppy, and that has worked, but when I try to access the CDROM for installation, the program says that it does not detect the Redhat 9 installation CDROM in the CDROM drive. What? It's in there! My new computer won't even detect the CDROM on startup! What is up?

Some older cd-roms have trouble reading CD-Rs. Have you trying just mounting it on said system to see if your drive will even read it?

I thought about it, but my very new computer won't boot it either.

where did you obtain the copy at?

teamstatic84 · 07-19-2003, 10:39 PM

I downloaded it off of Bit Torrent

are you sure you made the cds right? if you dont burn as image they wont boot

Look at the CD in any system that works, on the CD is there an .iso file or a directory structure? If there is an .ISO file then you did't burn with the correct options.

make sure the iso you downloaded has a correct md5 value... it has to be exactly the same as it is published on the server...

check that the cd was burned correctly... this is done by comparing the md5 value of the original iso image with the md5 value of the cd itself...

if they are not the same, then you have a "coaster"...

here's a good link about this "phenomenon":

here are the md5 values for the red hat 9 distro:
