So, what I would like to do is to take the Bootable USB and make it into an ISO.
Any ideas?
If none of the methods given so far work for you (that
troubleshooters.com link from SilverTip257, which tells how to convert a
'dd' copied file to an ISO using mkisofs, looks promising), here's a
method to do it in windows (or WINE, else I wouldn't bother posting it
to this list), using the free ImgBurn program (imgburn.com)...
1 - with the bootable stick plugged into the computer, start ImgBurn
2 - click on "Create image file from files / folders"
3 - in "Sources" browse to your USB stick
4 - for "Destination" choose where to save the ISO image
5 - on the Advanced tab choose "Bootable Disk" and check the "Make
Bootable Image" (also set Emulation Type as 1.44 floppy)
6 - in the "Boot image" dialog browse to the file "etfsboot.com" (or
whatever image your USB stick uses) that should be in the "boot" folder
on the USB stick
7 - in the field "Developer ID" put e.g. "Microsoft Corporation" and
enter "07C0" in the "Load Segment" field
8 - enter '4' in the 'Sectors To Load' field if your etfsboot.com file
is 2K in size, enter '8' if it's 4K (i.e. size of the /boot image file
in bytes divided by 512).
So, it's fairly straightforward as long as you change the emulation type
to 1.44 Floppy (most bootable USB's do *not* emulate a floppy disc when
booting; 'dd' won't do that for you by itself), and use 512 as divisor
of the /boot folder's image file size in bytes when setting the Sectors
To Load option.
