When you select install CentOS after 7 it will be wrong. Error message: that dracut: / # ... timeout lot.
I thought I was not doing the boot disk, then I redo it several times are the problem.
solve
By search engines, the results of similar solutions. Perform the following operations given the following information:
dracut:/# cd dev >dracut:/# ls |grep sdb
This way you'll see all the device information. Find sdbx, x is a number that is where you u disk
>dracut:/# reboot
After the restart, the install page modify press e
vmlinuz initrd = initrd.img inst.stage2 = hd: LABEL = CentOS \ x207 \ x20x86_64.check quiet as vmlinuz initrd = initrd.img inst.stage2 = hd: / dev / sdbx (you u disk location) quiet
Then press Ctrl + x to save enough. But during the operation, I found the beginning of the dev sdb inside the only sdb, sdb1 and sdb2, so I put it Sa tried again, he had said no img file.
I thought my computer can not install Linux , but then I found that they generally say that default is sdb4, but my dev there is no sdb4, but I have a dev sdc4, so I use sdc4
modification
vmlinuz initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64.check quiet
for
vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sdc4 quiet
Then press Ctrl + x appeared centOS installation interface.
Problem Cause possible to support different hardware vendors are not the same, because when you install CentOS7 interface selection system installation path and I found sdb1 sdb2 not mobile, but my computer's two hard drives.
In consultation with chiefs also have another solution for a U disk to re-write the installation image to install.
