bootable dvd cant boot even though bios configured

hi:)
i think you may have answered your own question 32 bit distro will work on 32 bit system 64 bit distro will work on 64 bit system. try and download the 64 bit distro and burn the iso for the laptops you want to run the distro and see if this works for you, by the way what linux distro are you trying to use?

differences between 32 bit and 64 bit distros >>> http://goo.gl/n9JgD

This is strange to me. I have 3 laptops, was trying to boot from linux distro 32 bit on all of them.

The oldest toshiba laptop is a 32 bit and the bootable dvd works !

My 2 newer Asus laptops 64bit cant boot the dvd. What gives?

All of their boot orders have also been configured. Asus even has a BBS option that can let me boot into dvd drive directly. On 1 Asus I only get a blank screen. On the other, no medium detected, cdrom boot priority indicated "boot ready".

Thanks.

Can the 64bits machines boot from some other bootable dvd?

An .iso cannot simply be burned to disk and expected to be bootable...

Sorry patio, but this is not true.

An ISO file is simply an image of a file, or files & folders. There are many bootable programs that are downloaded as an ISO file and fully functional after simply burning the ISO to disk. It just depends on whether the ISO includes a bootloader file or not.

He probably meant that he has to use "burn ISO" option in burn-software. Not just compile a new dvd and drag ISO to that compilation.

The linux distro site especially mentions that the img should be bootable onced burned. And it worked for the 32 bit. I also tried using 64 bit distro on the 64 pc in addition to the 32 bit version. I burned it using nero. Basically, I rightclicked the img file and opened with nero, and it burned the img.

I looked in the bios and saw sata config about ahci and ide. The config.on the 64bit is set to ahci. Should I even bother with the setting? Is this relevant? I afraid that messing around with this setting would make my pc unbootable.

here is ubuntu website explanatory on iso >>> http://goo.gl/gsrZ

Inexpensive "write once" CDs are a better choice for burning ISO images. Expensive CDs and DVDs sometimes work but are less reliable, perhaps because of higher burn speeds

i always use cdr with good results
