I used Hiren Boot CD (Some tool on it) to create 8 partitions for Windows XP and CentOS 6.

Now, CentOS6 Disk Utility reports for first partition:

"Warning: The partition is misaligned by 512 bytes. This may result in very poor performances. Repartitioning is suggested.",

and similar warnings almost all other partitions.

Since I already have both Windows (NTFS) and CentOS 6 installed, I was wondering is there any easy way of re-alligning them, maybe via parted?

Can someone write short to-the-point howto for repartitioning ext4 partitions (/boot especially)? NTFS partitions I can ghost without a problem and resize them when I returnin it on the HDD. It would be nice to experiment, but I am out of time.

I did fdisk -l /dev/sda> file and I can do dd to image file, but how about resizing/repartitioning?

I read somewhere that it is good to leave 1MB free before first partition, so it can be aligned?

Here's how my partitions look like on a box with F16. Afaik the anaconda in F16 properly aligns partitions. Note the initial start at 2048.

$ sudo fdisk -l

Maybe you could get an F16 CD/DVD and create the partitions with it?
