우분투 18.04에 윈도우 10 멀티부팅

윈도우 설치 후 재부팅하면 오랫동안 진행이 안되는 것 같은데 완료됨.
네트웍이 무선이 아니라 유선으로 연결을 해야진행되는 걸 수도 있음.
무선으로 연결해서 한참 기다려도 윈도우화면 안나와서 몇번 설치 실패.
유선 연결 후 20 ~ 30분 정도 기다린 후 정상 설치 됨. 무선에서 더기다려서 될수도 있음.

        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}
allprojects {    repositories {        maven { url 'https://jitpack.io'}
        google()
        jcenter()
