Burning the UNO Bootloader, AVRdude throws Messages:

avrdude: verifying ...
avrdude: WARNING: invalid value for unused bits in fuse "lock", should be set to 1
according to datasheet
This behaviour is deprecated and will result in an error in future version
You probably want to use 0xff instead of 0x3f (double check with your datasheet first).

avrdude: reading on-chip lock data:
Reading | ################################################## | 100% 0.01s
avrdude: verification error, first mismatch at byte 0x0000
0xff != 0x0f
avrdude: verification error; content mismatch

Although error messages are being made, the bootloader will work afterwards
