makeImg.asm []:
store byte a at FATEntry2+%-1
error: value out of range.

Code:
;-----------------------------------------------------------------------
;BootSector
;-----------------------------------------------------------------------
file 'BOOT.SYS'               ;512Byte

;-----------------------------------------------------------------------
;FAT table 1
;-----------------------------------------------------------------------
FATEntry1:
db 00h,00h,00h,03h,40h,00h,05h,60h,00h,0ffh,0ffh,0ffh

FATEntrySize = $-FATEntry1

db 9*512-FATEntrySize dup(0)

;-----------------------------------------------------------------------
;FAT table 2
;-----------------------------------------------------------------------
FATEntry2:

repeat FATEntrySize
  load a byte from FATEntry1+%-1
  store byte a at  FATEntry2+%-1
end repeat

db 9*512-FATEntrySize dup(0)

You have to make space for the data you want to copy.
Code:
;...
FATEntry2: rb FATEntrySize ;without this space we have nowhere to put the data.

repeat FATEntrySize
;...

Moving to main. There are no macroinstructions in this code.
