I am probably misunderstanding something. We seem to go backwards.

"Something" changed. If you now cannot see your USB drive in your 
list (press F12 during POST), there is no point on redacting 
instructions.

The following conditions are the ones that should give us the higher 
chances to have your USB drive bootable:

_ Standard MBR;
_ Only ONE partition;
_ The partition formatted as FAT32;
_ The partition is marked as "active" (AKA. "boot"able) in the MBR.

Then you need to have the content of the Clonezilla Live ISO (or the 
zip archive) expanded / extracted / copy (choose your favorite term) 
in the FAT32 partition.

Can you confirm this is the current situation? Can Windows Explorer 
see this content?

Boot into your BIOS settings. Look for something similar to SATA or 
IDE or NATIVE or AHCI mode. There might be more than one setting 
regarding this mode(s). Is it set to something like "IDE compatible", 
or "AHCI" or "RAID"? Please post your BIOS settings.

In your BIOS, is the USB controller enabled? Is USB 2.0 enabled?

In your BIOS, is there some "onboard IDE controller" setting? Is it 
enabled?

I am not asking to change any particular setting. I just want to 
understand the current situation.

With the USB drive connected, boot the system and use F12 during 
POST. Can you still see your USB drive listed somewhere? Possibly 
under HDD or under USB-HDD? Where is it listed?

We must regain the possibility to at least *potentially* boot to the 
USB drive before attempting any additional instructions.

Please use the above paragraphs / questions so to clarify the current 
situation. According to your answers, we might know how to go on.

Ady.
