Porteus

From the xfce cd you can use gparted which will help you resize the usb into a linux file system. Gparted is quite easy to use, it is quite intuitive.

Use ext2 as the additional new partition, as it will permit to store the information more tightly.

Personnally, I would resize the usb key as much as you can as finally, you want to reformat it to its original state after. Formating a new partifion under linux is usually a lot faster than under windows. But if you are more at ease with

I would back up the critical data just in case. Sometimes there is loss of data while resizing.

Then as explained above use the porteus installer and target the partition that you have just created. Don't forget to select install bootloader. The new partition shoud be different from /dev/sdax, so rather /dev/sdbx or /dev/sdcx or /dev/sddx, where x is a number. If you are not sure provide as asked previously output of fdisk -l command.

Finally, just follow fanthom's suggestions. Persistence in graphic mode is already added when you are on usb.

Thanks for the suggestions.

The usb drive is 4gb and has nothing on it.
Could it be left as FAT32? Would Porteus install on FAT32?
If I format it to ext2, I was thinking that I wouldn''t partition it and leave it as one large partition. Would this be OK?
Then, later, reformat it back to FAT32.

You will have to create a save.dat container. Porteus is linux, it works better on linux filesystem. However, a save.dat container could be added for persistence. See:

Good nite.

Thanks again.

If I use the ext2, then I won't have to create the dat cantainer. Is this right?

yep,that's right..and the better choice..
...it's almost 5am here in berlin...see you tomorrow.....bye..

Thanks for the help.

Time for bed for me too.

Reverting back to fat 32 will be real easy with gparted when you will be finished with porteus.
But you surely will be so fond of it that I would be surprised that you ever erase it. 8)
