help with bootable cd


Hello all I have just gotten a copy of redhat 7.3. I have never tried redhat so I would like to give it a try, but i cannot seems to make the cd bootable. Perhaps the process I am using is bad.

I start gtoaster. go to the Folder put all info into the burn pile. and then burn

I have tried entering the boot.cat and clicking make bootabel but nothing so far any help is appreciated.


Thanx
Gonus

Kind of basic, but do you have "Boot from CD-ROM" enabled in your BIOS?

This copy of 7.3, is that on disc? If so, is it bootable by itself? If so...

Just use dd to make an iso, then burn the iso with cdrecord:

dd if=/dev/cdrom of=/home/RH/disc1.iso
cdrecord dev=0,0,0 speed=8 -v -eject /home/RH/disc1.iso

Of course you'll need to replace the variables in the file, like if=INPUT FILE, your device, of=OUTPUT FILE, the location to where the iso will be
dev=THE DEVICE as shown by cdrecord -scanbus; and speed, the speed at which this will be burned, I usually go conservative, I am not in that big of a hurry

Cool

Well, if it's a cdrom, that already works just fine, and you are just burning like a back up copy or whatever, then that's the command.

If it's a cdrom that was made from a bunch of files, and was never bootable, then you need to make it bootable still.

SO, is the cdrom that is the original, already bootable?

Cool

I believe the original cd that I copied was bootable. It was not a burned copy so it should have been. Then I copied all the contents to folders then burned the cd's. The ones I make are not bootable.

Ah, now you see you didn't really want to do that. Some of the files on the CD are 'symlinked' to others, and when you copy them over (in Windows), you lose that ability, so even if you were to make a nice bootable CD, it would probably come back with some errors (although these would be recoverable, I'm sure). Even if you copied the CDs contents in a *nix environment, you still wouldn't have copied that catalogue files needed. You really want to either make an ISO from the 'original' (so long as the original boots from CD ok) or download yourself a new ISO, or even buy a distro from one of the many places that sell them cheap.

OR, if you say that your original CD (that you have in your posession) is bootable, a dd will work.

dd if=/dev/cdrom of=/home/wherever/rh/cd1.iso

No, the cd doesn't have to be an iso image, you are creating one from the files that are on the cd already.

Cool
