Let me talk more about it here:
I installed centos 7/red hat e...... 7 These two versions have an error here, error message: no default or UI..., installation said online, I have tried many times, many methods cannot be solved
After installing centos 6.5, after partitioning, it keeps [retry download]. The Internet says that because the mount point of the USB disk is [/dev/sda], you can only reinstall it.
After two days of trouble, because I had no problem installing before, I suspected that there was something wrong with my USB drive, so I just wanted to replace a USB drive.
3. All the way 【next】even if it is done
3 points to note:
When partitioning, you must look at which hard disk is carefully divided
The password cannot be too simple
Minimize software installation.
