Can PCs boot a CD-RW?

[Sup3rkirby]

This is really bothering me. I've been trying to revive an old PC and get a nice setup going in my room with these two PCs. I was planning on running either Xubuntu or ReactOS on the old PC while the new would be on XP. But it seems my old PC is without an OS. It has a regular CD drive in it, but I've tried using a fancy DVD-RW(lightscribe) drive on it with no results here.


You see, I buy RW disc because, well you can use them more than once. Good for burning music or data CDs on the go and not having to worry about only using them once or twice.

I've actually booted PCs and a laptop off of a DVD-RW disc before. In fact, I used to use those all the time. But I recently got some CD-RWs and didn't need to use a 4.7 Gb disc for a 500-600 Mb iso. But I have not yet been able to boot any live PC with these CD-RWs.

Today I tried to burn a copy of Xubuntu on a DVD-RW and used my DVD-RW drive, but the PC just won't boot it. It lights up and appears to be doing something, but then eventually boots the HDD(which has nothing on it).



What a shame. I'd hate to buy some CD-Rs and find that they won't boot either.


And as for burning these, I've actually burnt and re-burnt quite a few times and on several disc hoping maybe it was a bad write or the disc was bad....

Hmm...have you checked the BIOS to make sure the boot sequence is in the right order? Because I know I've booted off of a CD-RW before.

If your drive can read CD-RWs (which I'm sure it does), then go into your BIOS and change your boot order/sequence and make sure the CD drive is placed before the HDD

[Sup3rkirby]

I am well aware of the boot order setting in the bios, and that is set to boot up the CD drive before the HDD.

I actually can boot that PC with a CD, but it has only worked with a few older CD-Rs that I had made a long time ago. So those only have outdated linux distros on them...

I guess I'll just try to find an old DVD-RW distro that I made and see if that boots. If it does, then something is going one with my current burn settings or something. Although I've tried burning the CDs on 3 different PCs so far....

Fedora Core would be a good distro to try to use a DVD-RW to use, it is almost 3GB big though...

I am starting to think the problem could revolve around something in the version of linux I am using. But I wouldn't understand why.

The only linux distros that are working are older ones I've burned a long time ago. While these are also all on CD-Rs, It still seems that any new CD i've burnt will not boot on this PC. It is an older PC and maybe it doesn't support the new linux kernel or something along those lines. I really don't know though.

I've gotten some 2.x version of puppy to run fine(trouble with the installation though(after install boot is crazy slow with errors)), but the new 4.00 version of puppy doesn't even boot(meaning no grub menu or anything).

I'm not quite sure why this is. I hate to lose an old PC but all my working linux disc are pretty outdated and since none of them have any kind of online upgrade system or anything, It isn't looking good for this PC. I could use an old distro and just do updates, but i'm still using an old version of some linux distro then....


Is it possible for some older PCs to not support newer versions of linux?

If you put the CDRW in another PC and try to boot from it, what happens?

[vol7ron]

There's a lot of factors that go into booting.

#1 is the ROM on the CD/DVD reader itself. You may need a firmware upgrade.

#2 Could be with how the BIOS is seeing the CD/DVD reader, again a firmware upgrade should fix this.

#3 Is how the OS is encrypted onto DVDs/CDs so depending on how you put the OS install/boot files onto the disk could affect whether it'll work or not. For instance, Microsoft makes it real hard to just copy current OS cd's to a parallel writer.

#4 The type of DVD/CD-RW you are using also affects the performance of the system. Not all discs are of the same quality. Not to mention, some work better with the actual reader then others. I know I was having problems with an XP burn one time. The burn was error free (tried it on several discs too) what I found out is I needed to use a different manufacturer and then it worked.


Hope this helps

Well, I'm at work now and won't really be home till tonight, but I was thinking of trying a newer PC and seeing how well any of my new CDs/DVDs hold up.

A firmware update seems a bit hard without an OS on a computer though. And I don't know about choosing a different manufacturer. The CD and DVD-RW drive I've tried will run some old CD-R disc I've burnt, and those are the same brand and the new ones. The only difference other than the dates of purchase are the fact that the old ones are only CD-R and the new ones are all RW.

I've tried InfraRecorder and well as the NTI CD/DVD maker and even the Sonic burning program from an XP PC I have.


The only thing is, I am rather sure that when I take my CD-RW tonight and boot it in my newer PC, it will start up the live cd for that linux distro, as it should. And so in this case, it seems I'll be stuck either using an outdated version of linux or just not using that PC at all....

Btw, is there a way to boot a PC from a USB HDD? My guess would be you set this up in the bios, and possibly depending on the bios version and such, you boot the USB device before the HDD in the PC(SATA or whatever you may have attached).

[Sharky]

It's possible, but that depends on the machine. My laptop simply won't boot from a USB device, but has no problems in booting from a CD.

Do they still make boot floppies?
