Cocould not boot problem during installation of Fedora 20 and encountered errors

Installing fedora is simple. I don't know much about Linux. I never heard of it before I went to college. But I have been very interested since I went to college. I think it's amazing.

I used Ubuntu all the time, because I used ubuntu. Try to install fedora this time

I went to the official website to download the image, with ultraiso burn into the U disk, write mode USB-HDD + V2, and then in a broken computer to change the BIOS with U disk boot

Then ...... Error

Then display

Darcut-initqueue [309]: Warning: cocould not boot.

Darcut-initqueue [309]: Warning:/dev/Disk/by-label/Fedora-Live-Desktop-x86_64-20-1 does not exist

Darcut-initqueue [309]: Warning:/dev/mapper/live-RW does not exists

Starting dracut emergency shell...

Warning:/dev/Disk/by-label/Fedora-Live-Desktop-x86_64-20-1 does not exist

Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode. Exit the shell to continue.

Type "journalct1" to view system logs.

You might want to save "/run/initramfs/rdsosreport.txt/" to a USB stick or/boot

After mounting then and attach it to a bug report.

Dracut :/#

My idea is to confirm your labelbar first. rdsosreport.txt I really don't understand ......

Execute blkid, amount, and find the label is fedora-livecd

I do not remember the name configured in isolinux. cfg and syslinux. cfg.

No way, because Linux is a beginner, not a good match, simply put isolinux. CFG, syslinux. CFG, grub, drive letter name, and image file name should be changed to fedora-20-1 in a uniform manner. The name is casual, but the length of drive letter name should not be too long.

Then it will be okay if it is started normally. Principles ...... I am still at Google. I 'd like to write it down first. If someone can help me answer questions, I am very grateful.

The above is my situation. I don't know if it is useful to everyone ......
