bootable iso image

[thecrock]

I have an iso image of a bootable cd, when i burned the image to cd my laptop wont boot the cd, iget the message non emulation footing.

This is what i did.

Burned iso with alcohol 120
changed laptop settings so that it boots from cd
get error message abot emulation

anyone?

What is the CD supposed to be? An operating system like Linux or something else?

[thecrock]

operating system

[isogonic]

never used alcohol to burn a iso image before, but did you change the boot order sequence in the BIOS setup?

[thecrock]

yes

[Dv8ted2]

Did you finalize the image? ISO files usually need to be fianlized.

It sounds like the floppy emulation is not set correctly. I'll gt that when making an updated Windows CD with the latest patches, and forget to set the floppy emulation to none in Nero.

It would help if you said which OS, I know Windows needs to be set to none with 4 loaded sectors, not sure about different distros of Linux.

When i put the disk in my pc and start it up i get the message to boot from cd but in the laptop i am trying to install to i dont.
I've tried changing the bios to boot from cd but get back the message that the cd has no emulation footing.

I'm only going to burn this iso once more so any suggestions?

Something wrong with the laptop?

[thevoelk]

Since you didn't answer the question, I'm assuming your using Windows, and there is nothing wrong with your laptop.

The floppy emulation is wrong. Download ISO Buster, open up the ISO of the OS. Extract the boot sector, along with the remainder of the iso contents. Open up your burning program, Nero, Roxio ECDC, Sonic RecordNow, etc, and start a bootable CD/DVD project. For Nero, selct Enable Expert Settings, set the Kind of Emulation from the default of Floppy to None, set Load Segment of Sectors to 07C0, and set the number of loaded sectors to 4.

Add the contents of the OS CD to your project and burn. You can burn that ISO as much as you want, the ISO was made wrong and it won't boot. Plain and simple. If you made the image in Alcohol, you didn't enable the correct emulations settings. If you downloaded it, the provider made it wrong.

I am pretty sure Ghostburn , a free cd/dvd burning tool over at www.downloads.com will burn bootable iso image's , and create them as well ... might be worth a try

Use it's own built in burning engine , no other's .

It dose well with linux bootable disc's .

[thecrock]

Thanks for all the replies.

I only get problems booting the disk on a laptop, when the OS is installing the laptop closes down.
I have tried uninstalling my antivirus but i can't even get rid of that.

[thecrock]

I did everything that thevoelk told me to do and the dvd works in my pc but i can't get it to work on my laptop i get non emulation footing.

Actually, I don't believe you want floppy emulation when you are creating bootable OS cds. I learned this when creating a slipstreamed Win2k w/Sp4 bootable disc.

I uses BCD to create bootable CD. Is DVD bootable ? What program can I used ?

Yes, DVDs are bootable. You can use Nero and others to create them.

What does one transfer a bootable XP install on CDR to DVDR ?

You need to extract the bootsector image from the CD. You can use Isobuster for that. Then use Nero to burn the Bootable DVD using the Boot.img you extracted from the CD. Follow thevoelk's directions and you should be fine.

what everyone is forgetting is that many laptops can not boot from the cd - no mater if it is in the bios or not ..

because either they dont use drives that are bootable - or because the drive requires a driver

why is it is hard to re-install a OS on some laptops ...


this of course is not always the case ////

but he says it boots fine on a pc , just not the laptop, so he should not have to do anything to the disk -- it was made correctly ..

yep... I had this problem with an old HP 3300 laptop. my computer geek buddy made a bootable floppy that loaded the driver for the cd...

thecrock,

A quick GOOGLE search for "bootable xp install dvd" yeilded many references on how to made a bootable DVD with W_XP.

About your laptop, contact the maker or check their website to verify that it can boot from optical media.

1. Nero was default to its dosboot.ima. Do I name the boot section extracted by isonuster as an IMA file ?
2. can I leave the boot CD in a drive, and browse to the disk as a bootable logical drive ?

Thanks for all the info, and this procedure work for me.

1. If you do not have a bootable CD, make one with info from http://www.nu2.nu/bootcd/wxp/.
2. Use isobuster to extract BootImage.img to a folder.
3. Copy everythings else on the CD to a folder too.
-- From thevoelk --
4. Open nNero and start a DVD-ROM(Boot).
5. Select Enable Expert Settings, set the kind of Emulation from the default of Floppy to None, set Load Segment of Sectors to 07C0, and set the number of loaded sectors to 4.
-- more detail --
6. Select Image file, and browse to *.*, to get BootImage.img.
7. Copy all the rest of the BootCD content into the Nero project.
8. Add any application folders, since you now have 4GB of extra space.
9. Burn.

The fact that it apparently will boot on the PC verifies the disk is will in fact boot. Have you actually booted on the PC and what happens next?

You are stating that the disk does not boot on the laptop, yet you state that the laptop closes down "after beginning the OS install". It can be one or the other, but not both.

I believe this error message is an OS installation error, probably from some flavor of Linux. That is not an error he would see if it completely failed to boot.

Since the OP has twice declined to provide accurate info about exactly what type of OS disk this is, not much more point in guessing.

[thecrock]

Yes, so sorry. I tried another copy of windows and the computer kept closing down. Sorry about mixing things up.

Thanks for all the great advice.

The CD was bootable just not in the laptop. I got hold of another version and everything seemed fine but then the laptop kept closing down. The install would stop in different places so i didn't think it was the disc at fault-but it was the disc at fault as i found out when out of sheer desperation i burned another copy of it. The second copy worked fine on the first attempt at installing. Now i have xp on the laptop and everything is running fast as greased lightning.

So the original image i had was bootable just not in the laptop.
The laptop kept closing down because of a bad cd-r or a bad burn.
The second cd worked fine.

Sorry for putting everybody out with badly thought out posts, my head was in a bit of a muddle.

Thanks again to everyone who posted.

Peace.

There is a free program called BartPE, that can make you an OS disk on a dvd.

La solucion esta en instalar el sistema operativo con un cd que arreanque desde DOS y no desde wimdows. Si dispones de un CD de arranque basado en DOS todo solucionado, garantizado.
