Boot problem

[eagleamon]

Hi everybody, I lay this down because I've got a problem with my multiboot dvd, I mean:

I've burned it (and made it) on a computer and now it's perfectly working on this one.. but I've tried to make it work on some notebooks... but badfully, there's no way to get it out...

On the notebooks, After the CDshell menu (working), I've got the screen : Please wait while the installation check for your material (or something like this - Windows XP) and then black screen.....

Does someone have an idea ?

Thanks a lot !!!!!!!

One clue there, is it has to be something to do with your OS files for sure. Your CDshell seems fine.

Check if txtsetup.sif and setupldr.bin are edited properly. Also see if the boot-sector (pro1.dat) is edited properly, and whether CD idents are placed properly.

DO you think it's possible they're wrong despite it works perfectly for the first computer ? I've also tried it with VMWare, and I've got no problems..

Doesn't anybody else have a clue ? ?

This is just a clue, but it happened more than once that the cause is just a CD that cannot be read properly:

1) did you burn the CD at the LOWEST possible speed?

2) can you try the CD with CDCHECK?

3) try burning it again at the LOWEST possible speed and on another brand media (some work better than others on a certain burner)

I've checked with cdcheck, but all seems to be ok - no error - A weird thing is that it does the same on an other laptop but it works with all the PC i've tried...... :|

Well, then there are ONLY three possible causes:

1) The laptops are very old and their BIOS has the el-torito boot cd-rom specs badly implemented (VERY unprobable)

2) The laptops have dedective/worn out CD readers (possible)

3) The laptops CD readers are somewhat "weaker" than desktop ones, so that a CD that can be "barely read" by desktop PC is not read by laptops.

Only test you can make is #3 in my previous post:

try burning it again at the LOWEST possible speed and on another brand media

There are still some settings for burning the cd image file onto cd-r witch may solve the problem, here nero as exaple:

If you select the iso image file as source, there are 3 possible burning strategy:

1) TAO

2) DAO

3) DAO96

Principlely the DAO method works with already the most computers, bat sometimes the DAO96(Disk at one with raw data) can help. The TAO works with less PC, but try it harms nothing.
