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.
There could be several reasons for a BootCD not to start.
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.
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.
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?
If the above applies to you: While booting, Windows 95//98 accesses several files. Among these are the registration files. Unfortunately it is not possible to acccess the CD while writing. Without making certain arrangements it is not possible to boot Windows 95/98 from CD. Unfortunately these arrangements are very complex. The way to make a Windows 95/98 CD of this kind can be read up on in c't 11/99.
You have to use a bootable floppy disk, i.e. if the floppy is in the drive and you start up the computer, then the computer must start up without errors.
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.
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.
