Did that. Got this:

As mentioned I do not have raid, only identical drives. Also have two identical SSDs as boot devices. One for windows other for linux.
Unplugged the raptors & the install began. Finished, rebooted, now it would not go past the boot screen with the blue bar. Bar filled up then it sat there doing nothing.
Used ctrl alt del & when it was rebooting got this, 'could not log boot up - address already in use.'
Plugged the raptors back in & it got to about half way along the blue bar & went into a very slow crawl. Gave up in the end.
