Questions on BootCD

Can further sessions follow on BootCDs.

Yes and no.

You can use Nero to put further sessions on a BootCD but then this CD can no longer be used to boot.

The BootCD won't start

There could be several reasons for a BootCD not to start.

  1. The BIOS has to support booting from BootCDs. Even if there is a comment in the BIOS that it is possible to boot from CD, this unfortunately does not always mean that all types of BootCD are supported. There are the following three types of BootCD
  2. Harddisk-Emulation, Floppy-Emulation, No-Emulation

    There are BIOS variants which only support one or two of the three types of BootCD correctly. Therefore you should always use the newest Flash-BIOS version.

    Also: In the "BIOS FEATURES SETUP" the boot sequence must be set so that CDROM is at the start. This setting only applies to devices on the onboard IDE-controller.

    If you have connected an SCSI Using the CD-ROM drive:

    The boot sequence should be set to A,C as, depending on the emulation type of the boot CD, the CD-ROM drive will be routed to the drive letter A. Depending on the SCSI-Controller used, a Boot-ID can be determined in the BIOS of the SCSI-Controller or the CD-ROM drive must be set to ID0 or 1. If you have a controller without its own BIOS, which is dependent on an SDMS kernel in the motherboard bios, then no changes can be made to the controller settings and saved.

  3. The CD-ROM drivers do not support booting from BootCDs.
  4. Either they are irritated by the fact that when reading from drive A (Floppy emulation) or from drive C (harddisk emulation) they are reading from the CD or they do understand the special format of BootCDs.

  5. If you have used the floppy emulation, then it must be ensured that the floppy disk itself which you are using is bootable, i.e. if you have a floppy disk inserted and you start the computer again, then the computer must be able to run up without an error messsage.
  6. Some DOS ASPI drivers can not handle BootCDs. Please download the newest ASPI driver version and use it. Drivers which have proven to be good are those included on the disk and included with Windows 98.

How do you burn a bootable ISO Image file?

An image file which is meant to be bootable is burned in th same way as you burn an ISO image files, i.e. definitely do not use a Boot CD (Floppy-Emulation, Harddisk-Emulation).

Please read on in Can Nero burn ISO images?

Error messages when booting from CD

There are no files on the BootCD, why?

A BootCD which was created with Nero , as a general rule consists of two areas: the area with the bootable session and the area with the ISO9660 Session.

The bootable session can only be seen if this session is also used to boot, i.e. this data can only be accessed if you have booted from the CD. Depending on the emulation type, this is drive A (floppy emulation) or drive C (harddisk emulation). The area with the ISO9660 session can always be accessed providing the CD-ROM drivers have been loaded.

Why can't all partitions be selected?

You can only select partitions which are a max. of 630MB large. As there can be numerous other data structures on BootCDs, larger partitions can not be selected as the source of a Boot-Image.
