RE: [Wlug] Partition table blues

by Martin, Eric

All fdisk /mbr does is replace your mbr with windows info...the most it would screw up is grub / lilo (what ever is in your mbr). That can be replaced with any livecd and a quick command from grub or lilo. -----Original Message----- From: Gregory Avedissian [mailto:gma2004@verizon.net] Sent: Sunday, July 25, 2004 11:43 AM To: douglas.waud(a)umassmed.edu; Worcester Linux Users Group Subject: Re: [Wlug] Partition table blues Hi Doug, I haven't tried fdisk /mbr because I don't really fully understand what it does and have never seen a good explanation of how it will affect linux partitions. This morning, I read that it shouldn't be used on disks that have more than four partitions. I have five partitions and some unclaimed space. I might try it later today. Beside that, anything of value is on the linux side of the disk. (That's not a microsoft slur, it's just where I have my files.) So, while I would like to be able to get the whole thing back to its original working order as a learning exercise, I'm more motivated to get to the linux partitions.

Well, if your only keeping your windows partition around to watch DVD's, that's something that you've been able todo in linux for a long time. Check out mplayer / Xine and Ogle.
