Hello An operating system password should not affect your ability to boot from other operating systems. Some pre-installation environments do not support USB 3.0. Make sure USB 3.0 is disabled when trying to boot from operating systems/environments that do not have driver support. That may be what is causing the boot errors. You have the option in the PERC to perform a full initialization. A full initialization is similar to writing zeroes to a drive. You may need to create a virtual disk to perform a full initialization. You can check in the controller manual. [URL] Thanks
Hi,  I'm trying to erase hard drives on a Powerdge R730 that has a Windows password.  I haven't been able to boot from a Windows 7 or Dban USB drive.  I just get an error.  I think I've disabled the RAID and the Virtual Drives so I should be able to format the 4 x drives individually, right?   Why can't I boot from the USB?  Thanks for any info or suggestions. - Steve
