Either Virtual or RAID Disk Is Present

Troubleshooting

35 solutions

Disable any virtual disk.
Disable RAID in BIOS.
Disable Intel Rapid Storage Technology (RST), if available.
If the issue remains, find drivers/services beginning with iaStor using DriverView or ProcessHacker and disable the service.
If none of these steps resolve the problem, try reinstalling Windows.

Advanced Fix

Use this RAID/IRST guide to disable RAID/IRST as safely as possible if Windows was installed using RAID/IRST.

If IRST/RAID is already disabled, locate drivers/services beginning with iaStor. This Intel RST information may help.
