No; how you load the bootloader hex file into the pic is immaterial. In fact, you cannot program the bootloader firmware itself using the MCS loader; that would be a chicken-and-egg situation.

Do you have another programmer at hand? Or, you could perhaps build a simple JDM type programmer for initially downloading the bootloader firmware into the PIC. After that, the bootloader should work, and you would not require the programmer (for that chip).
