I. Description of the problem
First describe the situation, that is, in the boot process, when reading the bar read
[OK] Reached target Basic System
After this line is stuck, it's not going down.
Second, Seek solutions
In fact, this problem was discovered two years ago, but it was also possible to install the system by CD-ROM, recently because the SSD removed the optical drive bit, resulting in the inability to use the CD-ROM installation system, had to bite the bullet to find a solution
Just started to think that the reason is stuck because of nouveau driver, so in the grub2 of the boot item "Nomodeset" and "nouveau.modeset=0" have tried, but can not solve the problem
So consider probably not because of the nouveau drive problem, and then from the CentOS wiki to see, starting from a version of CENTOS6, ISO has a special way to load, resulting in some software from the ISO burning to the USB flash drive problem
Because I have been using UltraISO to burn the U disk, so consider whether it should be replaced by a software to burn, so have tried Rawrite-1.0.4.0,win32diskimager and other software, and then found that there is no egg, But there's a problem that doesn't lead into the system at all.
Third, the solution
Finally, search the Web page, finally found a solution, first in the GRUB2 using the key ' E ' to edit an entry
SetParams ' Install CentOS Linux 7 '
Linuxefi/images/pxeboot/vmlinuz inst.stage2=hd:label=centos\x207\x20x86_64 Xdriver=vesa Nomodeset quiet
Initrdefi/images/pxeboot/initrd.img
Then modify:
SetParams ' Install CentOS Linux 7 '
Linuxefi/images/pxeboot/vmlinuz Linux dd Nomodeset quiet
Initrdefi/images/pxeboot/initrd.img
Then use Ctrl+x to execute the above modified startup item
The details of the hard drive device are then listed on the screen, and we pick out the code for the current USB drive as media (e.g. SDD4) from the list.
Then restart the system and modify the boot entry to:
SetParams ' Install CentOS Linux 7 '
Linuxefi/images/pxeboot/vmlinuz inst.stage2=hd:/dev/sdd4 Nomodeset Quiet
Initrdefi/images/pxeboot/initrd.img
Then use Ctrl+x to start the normal installation process
