Hi all,

I tried many ways to make a bootable CD (from some books, MSDN, Slobodan's
example in this NG), but whatever I did, after FBA I cannot get a recognized
ElTorito Disk. In FBALOG.TXT in place of:
...
Disk0 signature = 0xC4B6C4B6.
Disk1 signature = 0x4F544C45.
Disk1 is an ElTorito disk.
....
I found:
...
 19:59:03 PM - Found 3 Hard Disks.
 19:59:03 PM - Searching for El Torito disk.
 19:59:03 PM - Disk0 signature = 0xC4B6C4B6.
 19:59:03 PM - Disk1 is raw.
 19:59:03 PM - Failed to get disk1 signature, error = 0x15.
 19:59:03 PM - Checking Start value in
System\CurrentControlSet\Services\redbook key.
 19:59:03 PM - Resetting Start value.
 19:59:03 PM - Checking Start value in
System\CurrentControlSet\Services\Imapi key.
...

An El-Torito PnP driver was loaded:
...
 19:56:43 PM - [FBAAddDevInstanceId]
ELTORITO\ELTORITODISKDEVICE\1&2AA0FFE4&0&0000
...
and EWF seams to be OK (ends with status 0x0).

WHY ??? I do not understand what's going wrong . I boot from the HDD and
the PreFBA CD is in the CD-ROM. I don't find any discussions about this
problem. If this is important: I use Nero 5.5.10.35 to burn a RW CD .

Thanks,
Emil
