Description
VMS cannot boot due to damaged boot block
If the system disk is accessible in read-only mode, this is because Charon detected a Windows partition on the disk. In such a case, the boot block repair operation will not succeed and you will have to re-create the disk (Windows disk partition removal) and perform a full VMS system disk restore.
This procedure is also requested when moving a system disk from VAX 7000 to VAX 66x0
