Got the answer. Current code doesn't support El Torito CD emulating a HD.
In 'src/VBox/Devices/PC/BIOS/rombios.c' I found following description:
// NOTES for El-Torito Boot ([EMAIL PROTECTED])
// - CD-ROM booting is only available if ATA/ATAPI Driver is available
// - Current code is only able to boot mono-session cds
// - Current code can not boot and emulate a hard-disk
// the bios will panic otherwise
