Attach the fault screenshot:

1: use UltraISO to burn the system disk, and the installation image is centos7.4

2: server type IBM Huawei Dawn

This problem occurs in the installation:

[ok] starting dracut initqueue hook

To the next line will not move, there has been no response! Further down is the problem of pulling out the USB flash drive!

So let's solve this problem now:

Step one:

After restarting the device, select F12 (IBM installation), press e to enter and modify it when you reach the startup interface.

=

Modify the default information (default information):

1234setparams' Install CentOS Linux 7'

Linuxefi / images/pxeboot/vmlinuz inst.stage2=hd:LABEL=CentOS\ x207\ x20x86_64 xdriver=vesa nomodeset quietinitrdefi / images/pxeboot/initrd.img

Explanation: standard red is the default U disk location, but now the default can not be found, we, to find the specific location of the plug-in USB disk identified by the server, need to change ~!

=

Modify to (modified information):

1234setparams' Install CentOS linux 7'

Linuxefi / images/pxeboot/vmlinuz linux dd nomodeset quiet

Initrdefi / images/pxeboot/initrd.img

Explanation: re-obtain the location information of the accessed USB disk after modification

After the modification, press Ctrl + X to execute the following figure

(ps: the photo was not taken because of the rush to deal with the problem in the computer room)

This picture is the most important:

Part one:

1: it is found that it is the relevant information of the disk, what you pay attention to here is the serial number, because when you press the number 1, it will be refreshed, and the serial number will change, that is, the position of the U disk will appear.

The second part:

1: observe carefully that the serial number 4 appears. This is the location of your flash drive. (sdc1 on the scene) Note: there is no such thing as sdb* for all flash drives. [remember your USB device path]

2: pressing the number 4 will show the directory where your flash drive is located, the prompt is in / dev/sdb4, then restart, flash drive starts, and boot modification

In the end, what we changed is:

Setparams' Install CentOS Linux 7'linuxefi / images/pxeboot/vmlinuz inst.stage2=hd:/dev/sdb4 nomodeset quietinitrdefi / images/pxeboot/initrd.img

This picture shows that after the final modification on the site, it can be guided normally.

Overall investigation ideas:

Restart →→ press e to modify boot →→ ctrl+X →→ to find the correct USB disk location →→ restart modify boot →→ restart normal recovery.

At present, only Centos7.4 will have this new problem.
