CDBOOT: Cannot boot from CD - Code: 5

When I attempt to boot from my Windows 7 install disc, I get this message on a black background:


CDBOOT: Cannot boot from CD - Code: 5


I'm using a late-2008 13-inch aluminum MacBook running OS X 10.7.


I've attempted burning the install .iso file multiple times (creating a couple of useless DVDs) at the slowest speed possible (which seems to be 2.4x, according to Disk Utility), and that has not solved the problem.


I haven't been able to find any help on this issue for a Mac user who doesn't already have Windows installed. (There seem to be solutions for people who are already running Windows).


Can anyone help?

MacBook, Mac OS X (10.7)

Then the issue might polnt toward the optical drive itself, rather than create more coasters, seeing you have tried slowest burn speed.


Note: burning Lion DMG with Disk utility also can fail if burned from the desktop, and needs to be done from inside Disk utility.

Only other avenue, swap optical drive or get Windows on physical media. Schools usually offer phsical media for an extra $19, or If you have access to a PC with Windows that can also burn ISO.


some MacBooks from 2008 supported Vista 64-bit back then, only to have only MacBook Pro in Late 2008 be supported (?? got to keep "Pro" differentiated?) and had trouble installing. There is a list of Macs that support / do not support / 64-bit versions.

Hi,


I had the verry same problem and I did multiple things I thought that could fix this problem.


Point one, the burning speed has nothing to do with the quality of your boot disk, you only have to lower burning speed if your burning process fails. So remind this for future burning problems.


1: I did the Lion software update.


2: I got another .iso file, burnd it and made a new partition in bootcamp and ran the setup again.


This time it worked really fine. But I'm not shure wether it was the SU or the new .iso... I checked the SU summary for the lion system update, but there was nothing to find on a boot camp bug and since they've improved boot camp it should work better 🙂


I have a 27" imac with the 2TB drive and Solid state so I was thinking that maybe it depended on which fysical drive I made the firtual bootcamp drive. But I tested the new W7 Boot disk on both fysical drives and it worked on both.


UPDATE: I found the reason... I compared the two copies of windows 7 boot disks and the one that works had a different name... Your boot disk should be called "CD_ROM" if not, the bootsequence will not recognize your DVD as a CD which appears to be nescesary for the installation process.



Sorry for the incomplete english, I'm from Belgium.
