优盘(U盘)安装Fedora报错无法安装

dracut Warning: /dev/disk/by-label/Fedora-Live-Scientific-KDE-x86_64-20.iso does not exist
dracut Warning: /dev/mapper/live-rw does not exist

在boot界面时,“Tab”,然后下面一长句启动参数

vmlinuz0 initrd=initrd0.img root=live:CDLABEL=Fedora-Live-Scientific-KDE-x86*64-20.iso rootfstype=auto ro liveimg quiet rhgb rd.luks=0 rd.md=0 rd.dm=0

把其中的CDLABEL=Fedora-Live-Scientific-KDE-x86*64-20.iso 改成CDLABEL=[U盘的Label名称]即可。
