Description of problem:

After doing a complete wipe of a USB stick, using Gparted to lay down a new partition table and a FAT32 partition yields an unbootable Master Boot Record..

I hit this problem while testing the liveusb-creator, and it causes your stick to boot up to a black screen with a blinking cursor.  A workaround could be to ensure that the system-wide mbr.bin matches what is on the drive?

[root@x300 ~]# dd if=/usr/share/syslinux/mbr.bin bs=512 count=1 2>/dev/null | hexdump -n 2 | head -n 1 | awk {'print $2;'}

After zeroing out drive, and doing a fresh msdos partition table in Gparted

[root@x300 ~]# dd if=/dev/sdb bs=512 count=1 2>/dev/null | hexdump -n 2 | head -n 1 | awk {'print $2;'}

Using `livecd-iso-to-disk --reset-mbr` fixes this issue, but I have seen many people hit this problem and it is not obvious what causes it.

Version-Release number of selected component (if applicable):
git HEAD of livecd-tools
gparted-0.4.5-1.fc11.x86_64
parted-1.8.8-17.fc11.x86_64

How reproducible:
Always

Steps to Reproduce:
0. dd if=/dev/zero of=/dev/sdb1 bs=1024 count=1
1. Open up gparted, lay down a new msdos partition table
2. Create a new FAT32 bootable partition
3. Run the livecd-iso-to-disk (without --format or --reset-mbr)
  
Actual results:
Machine boots to a blank screen with a blinking cursor

Expected results:
USB Stick should boot into Fedora
