LL2 not booting if one extended partition is formatted to FAT 32

[gold_finger]

I don't see anything that would cause that problem so it still makes no sense.  At this point, let's try wiping out the whole drive and starting over.  If there is anything on there that you need to save, do that first.

*  Boot with live LL DVD

*  Open GParted and delete all partitions on the USB drive.

• Delete logical partitions before extended partition
  
• Delete extended partition
  
• Delete primary partitions
  
• If you can't delete swap, right-click it and choose "Swapoff" first, then delete.
  
• If you can't delete other partitions, right-click and choose "Unmount", then delete.
  

*  Click "Apply" button (arrow button under word "Help") to finalize deletions.

*  Now make a new partition table:  Device -> Create Partition Table -> msdos

*  Make the following new partitions with GParted:

• Primary partition -- 25GB -- Ext4 formatting  (this will be root)
  
• Extended partition -- size = rest of drive, 475GB
  
• Logical partition -- 8GB -- Swap
  
• Logical partition -- 100-125GB -- Ext4 formatting  (this will be /home)
  
• Logical partition -- 342-367GB -- NTFS formatting  (this will be /mnt/Windows)
  
• Click "Apply" button to finalize making your new partitions.
  

*  Close GParted and start the installer.

*  Choose "Something Else" option, then on the partitioning page:

• Highlight 25GB partition, hit "Change", then
  • [li]Use as = Ext4 file system
    
  • Mount point = "/" (root)
    
  • Size = leave it at 25GB that you made with GParted
    
  • Format Box = does not matter (you already formatted with GParted)
    
  [/li]
  
  
• Highlight 100-125GB partition, hit "Change", then
  • [li]Use as = Ext4 file system
    
  • Mount point = "/home"
    
  • Size = leave it at 100-125GB that you made with GParted
    
  • Format Box = does not matter (you already formatted with GParted)
    
  [/li]
  
  
• Highlight 342-367GB partition, hit "Change", then
  • [li]Use as = NTFS file system
    
  • Mount point = "/mnt/Windows"  (you will need to type that in -- no quote marks.)
    
  • Size = leave it at 342-367GB that you made with GParted
    
  • Format Box = does not matter (you already formatted with GParted)
    
  [/li]
  
  
• No need to do anything with Swap partition.  Installer will use it automatically.
  
  
• Near bottom of window, "Device for boot loader installation" = /dev/sdb (or whatever the device name for the USB drive is).  It will be pre-filled with /dev/sda.  You need to change it to the USB drive designation.
  

*  Double-check your entries, then finish the installation

If you follow these steps and it refuses to boot properly, then I have no idea what is going wrong.
