Changing partition sizes on dual boot disks.

[JD]

Hi all.
I have a dos partitioned drive.
partition 1 has windoze
there is no partition 2 (it was deleted and it's space added to partition 1,
using the old software called "Partition Magic".
partition 3 is fedora
partition 4 is fedora's swap.

Fedora partition is only using 3% of it's available space:
$ df -k /
Filesystem     1K-blocks     Used Available Use% Mounted on
/dev/sda3      903432024 24820728 832696536   3% /

$ df -k /sda1
/dev/sda1        42015740   41972804      42936 100% /sda1


Can parted handle
     1. shrinking partition 3 (i.e. starts at a numerically higher block 
number)
     2. fixing the installed grub so that I can still boot fedora,
        or would I have to boot a live fedora and install grub from
        live fedora?
     3. adding the freed space to partition 1 so that windoze can
        see it and use it as part of it's partition 1?

P.S: I will be backing up sda3, so no fear there. Ditto with sda1.
Thanx.

having recently converted a win7 laptop to a dual boot, i would suggest
you take time to pull "gparted" and forget about using older
"parted".

you can pull latest release from;

http://gparted.org/livecd.php

do read the page and links to insure you are familiar with what you
wish to do.

*further thought*

as long as you will be making backups of both linux and oos,
you really do not need to 'move' linux on sda3.

i would suggest;

  delete old sda3
  create new sda2 as swap
  create new sda3 as /
  restore linux to sda3

time it would take to restore linux to sda3 will not be that much longer
than a 'move' and you will gain swap partition.

This will be two steps.  Shrink partition, then move it.  Gparted would 
let you set it up as one step, but it is done in two.

Grub should be fine.  You don't need to do anything.

Yes.

I also recommend the use of gparted from a USB live boot.
