Hi. I am going to install Ubuntu as a second OS on my Laptop, which is currently running XP pro. Out of my 80 Gb hard disk I'm thinking 10Gb winXP, 20 Gb Ubuntu and the rest as a shared FAT32 partition. Now my question is concerning the 1024 cylinder boot code limitation. I have problems understanding it. Will both my OS partitions need to start before the (in my case) 8 Gb limit? In that case, it will be a problem for me. Also, if I move my windows partition beyond the limit to install Ubuntu, and it does not work, It will be a problem to move it back. Any pointers are greatly appreciated. (I'm putting this in Win forum because I'm already pretty sure that the Linux OS partition does need to be within the limit).
