[KFUG] fdisk에서 파일을 쓸 수가 없습니다.

[smiles <smiles@xxxxxxxxxxxxxxxx>]

윈도우를 사용할 때만 boot0cfg -B ad0 명령어를 이용하여

easyboot를 쓰고 평소에는 fdisk로 MBR영역을 초기화해서

부트로더 없이 사용하고 있습니다.

그런데 평소에는 잘 되던게 makeworld 를 한 후부터

fdisk를 이용하여 MBR영역을 초기화하려고 하면 마지막 저장할때

fdisk: can't write fdisk partition table: Operation not permitted

에러가 발생하는군요.

그 이유를 도무지 모르겠습니다.

도와주세요.

Do you want to change the boot code? [n] y

We haven't changed the partition table yet.  This is your last chance.
