maybe the reason you didn't receive any answer about your problem till now is that you choose the wrong list for your problem the right one is probably -questions anyway: you probably lost the partiotion table as well as mbr. if your filesystems didn't reformatted or erased - all is fine, you don't have to panic since all your information don't lost. if you lost your partition table, you can recover. for this you must find the first sectors of you partitions. all this recovery staff you should do on some another machine or booting from fixit cd, but the first is the best. the first sector of your first slice (let's call it right) starts probably on 63 sector. create it (fdisk) with some reasonable size, say 500Mb. after this try disklabel (if it has several partitions) or fsck to see it's real size. probably you can use some another util for this - no matter. the main idia is that you recover you partition table by content of your partiotions. you may find useful for this dd(1) and file(1) utils. sorry i have no time now for bigger explanations, also i did such staff several years ago (there was even worse case - i erase the disklabels on fbsd slice) and i don't remember some exact things, but i think you will overcome this. regards On Saturday 29 January 2005 05:01, you wrote: > Chris Shenton <chris@shenton.org> writes: > > So I booted from floppies, went to Wizard mode, did the Install > > FreeBSD Bootmanager.
