From: "mp" To: Cc: Subject: Re: amd64/141060: [install] Can't install 8.0-RELEASE on the server where 7.2 works fine [regression] Date: Fri, 8 Jan 2010 00:32:47 -0500 If 7.2 was installed on a "dangerously dedicated" drive, then the 8.0 sysinstall bsdlabel does not automatically recreate a standard MBR on the disk. You can try to fix this by starting a fixit shell from sysinstall and issuing the command: dd if=/dev/zero of=/dev/ad1 bs=512 count=1025 where ad1 is the dangerously dedicated device. This corrected the issue for me. Also, you can read more about this from the mailing list archives: http://lists.freebsd.org/pipermail/freebsd-questions/2009-December/208759.ht ml Thank You, Mike Duchene
