I created a new fat32 partition from free space on my 40GB hdd. Now my dual
boot W2K/Mandrake won't boot.

I used the "Disk Manager" feature in W2K Pro to create a fat32 partition. It
complained that another program was using the hdd or something but I managed
to format it anyway and use it within W2K.
Now I can't start my linux installation. The W2K still boots.

This is my partition map:
Primary HTFS 7.81GB
Extended
494MB / ext2 or ext3
243MB swap
2.93GB ? ext?
4.6GB /home ext?
3.91GB fat32   << Here's the new one I just made. (G:)
14GB FREE
3.91GB fat32   << Old part. for sharing .mp3 and transfering between OSs.
(F:)

Here is my error message:

Activating swap partitions: swapon: /dev/hda7: Invalid argument    [FAILED]

/dev/hda9:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2 filesystem
(and not a swap or ufs or something else), then the superblock is corrupt,
and you might try running e2fsck with an alternate superblodk:
	e2fsck -b 8193 <device>

I tried deleting the newly created fat32 but my Mandrake 8.1 still won't
start.
