Full System Recovery fails with "Error restoring Master Boot Record".
Full System Recovery requires int13 extensions supported by BIOS.
Attached EXTBIOS.EXE utility which shows whether int13 extensions are supported. Add utility to MS-DOS bootable floppy or add it to FSR bootable floppy, boot in DOS and execute.
If BIOS doesn't support int13 extensions the only workaround is to install Windows operation system, install Recovery Solution Agent, register using existing account and perform rollback. Note that all original partitions on disk(s) should be recreated manually prior to rollback.
