I understand that on the grub file you need to put all of this, so that you can select the proper version when you boot.

If I have a 8GB USB stick:

1 partition of linux of 4GB /dev/sdb1 *

and

1 partition of win 95 4GB /dev/sdb2

then I put all the operating systems ISO files on /dev/sdb1 and make it bootable.

The problem I have, is that if I boot the operating system then when it loads up and I want to have access to the hard drives, well I do not have access to /dev/sdb2 since it does some sort of a loop back on the entire USB stick or /dev/sdb.

Well when you load it up it would be /dev/sda when you are installing the grub from linux onto the USB stick, it is /dev/sdb

But is there any way that I could make the loop back just for the first partiton and have access to the second partion?

I suppose I would have to mount the second partition to have access to it, but that is okay.

But I want to have access to the second partition. How do I do that?? What do I need to put in the grub entry to have access to the second partiton???

Because I do not have access to it. The grub entry loop back is for the entire USB stick!

Could you give me the 3 Grub Entries??? the GRML 64 full , the GRML 64 small and the GRML 32 small ?
