The following reply was made to PR i386/121124; it has been noted by GNATS. From: Volker <volker@vwsoft.com> To: bug-followup@FreeBSD.org, dan_strick@sbcglobal.net Cc: Subject: Re: i386/121124: FreeBSD 6.3 installation deletes MBR partition Date: Thu, 28 Feb 2008 22:22:15 +0100 Dan, unfortunately your partition table seems to be seriously broken if the information you've posted is correct. slice 1 starts at 63, has a size of 8209152 slice 2 starts at 8209214, size 1 slice 3 starts at 8209215, size 8225280 slice 4 starts at 16434495, size 143637165 If you're manually calculating the start sectors, you'll see there's an overlap, which is deadly while installing an OS. Your partition table should look similar like: slice 1 start at 63, size 8209152 slice 2 start at 8209215, size 1 slice 3 start at 8209216, size 8225280 slice 4 start at 16434496 That could have been the reason why the partition editor gave you a warning. I'm wondering if the maintainers can see if there's chance to complain clearly about a broken partition table before writing a new mbr? But I suggest to backup all your data, repartition your disk and install everything.
