minhtt159

PCs have SMBIOS data containing small amount of identifying information. One piece of information in this SMBIOS data is the universally unique identifier. Some PC and motherboard manufacturers fail to set this, often leaving the UUID set to 03000200-0400-0500-0006-000700080009.

If your system uses an AMI firmware (sometimes called AMIBIOS), you may be able to use AMI utilities to reset the UUID. Obtain AMIDEEFIx86.efi and an EFI shell executable, such as from inside m1ujt73usa.zip for the Lenovo ThinkStation P330 Tiny download center.

Once you have those two files, create USB drive with the FAT32 filesystem and the following structure:

\
  \AMIDEEFIx86.efi
  \efi

	# strip 'iPhone' or 'iPad' and the comma from the product type 
	short_product_type=$(echo "$product_type" | sed 's/iPhone//g; s/iPad//g; s/,//g' )
