NOTE: A boot virtual disk that is in a Failed state prevents the operating system from booting.

To investigate the cause, check for the following:

• Whether the virtual disk is in Degraded status because one of the physical disks of a RAID 1 or RAID 5 virtual disk has failed, or one of

the physical disks of a RAID 10 virtual disk has failed. Press Ctrl+R and verify if the physical disks are oine or missing. Remove and

replace a failed physical disk. A second physical disk failure could cause a Degraded virtual disk to change to Failed status.

• Whether the virtual disk is in a Failed status because one or more of the physical disks have failed. Press Ctrl+R and verify if the

physical disks are oine or missing. Remove and replace the failed physical disk or disks.
