VMware virtual machine does not restart after restore
The virtual machine may have been configured as follows:
At the time of the backup, the virtual machine had a combination of SATA and SCSI disks, or of SATA, SCSI, and IDE disks.
The guest OS resided on one of the SCSI disks.
The virtual machine when restored may attempt to boot from the SATA or the IDE disk. The boot attempt fails with the message "Operating system not found."
VMware has identified this problem and will address it in a future release.
As a workaround, reconfigure the BIOS on the virtual machine to boot from the correct SCSI disk.
