first just open up a terminal (or konsole) window. It will be in main-menu->system tools->Terminal and do the following :
[root@localhost root]# fdisk -l
Disk /dev/hda: 40.0 GB, 40057224704 bytes
255 heads, 63 sectors/track, 4870 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 2435 19559106 c Win95 FAT32 (LBA)
/dev/hda2 2436 4870 19559137+ f Win95 Ext'd (LBA)
/dev/hda5 2436 3653 9783553+ b Win95 FAT32
/dev/hda6 3654 4804 9245376 83 Linux
/dev/hda7 4805 4870 530113+ 82 Linux swap
Here we use the command fdisk -l to find out the information about the hardisk. The output obtained was for my hardisk and you will get a different output for your hardisk.
Observe the entries which have Win95 FAT32 (LBA) These are the windows partitions :
Now to mount these make new folders (equal to the no. of windows partitions) and use the mount command to mount these.
suppose u create the folders in the /mnt/ directory like /mnt/win1 and /mnt/win2
Then use the command :
mount /dev/hda1 /mnt/win1
to mount a windows partition. Observer that the /dev/hdaX entry is the one corresponding to the windows partition u wish to mount.
Go to /mnt/win1 and u will find all your windows files there.
Also don't try to mount the partition that has Ext'd written alongside it. It won't mount
Hope that helps
