how to resize my boot partition

Hi All,

I installed gparted to resize my partitions. I have 2 harddisks

hda = 20GB and is NTFS running WinXP
hdb = 40GB ad is partitioned as follows:

partition f.s. mountpt size flags
/dev/hdb1 ext3 / 35.73 GiB boot
/dev/hdb2 extended 1.54 GiB
/dev/hdb5 linux-swap 1.54 GiB

What I'd like to do is resize hdb1 to 15GB and format the remaining 20GB into FAT32 to be able to share data between Linux and Windows.

When right-clicking hdb1 I can choose "unmount" but since linux is running (d'uh) i can't unmount it, let alone resize it.

How do I go about this without a reinstall? Will reinstall if I have to but I guess there must be some way of doing it without having to wipe the entire disk.

Best regards and thanks in advance for your advice,

Gparted can also be downloaded as a livecd. Burn it to disk so you can do the partitioning without Ubuntu running.

Just about any "live CD" linux will have GParted or QTParted---either one will do what you want.
Be sure to back up important data first (both drives)

While you are doing this, I would recommend getting rid of the extended partition which is used only for swap. Put swap at the end of the drive, but as a primary. Then, if you need more partitions, you can create an extended partition that fills all the available space.
