During the imaging process, the imaging GUI and splash screen are distorted.



This issue is fixed by passing the nomodeset kernel parameter, which can be can be set in the following ways:

  • Case 1: Manually for bootcd.iso and PXE boot:

Add boot option nomodeset while selecting the boot mode (Automatic, Manual etc.) from bootcd.iso or PXE menu.

  • Case 2: Automatically for PXE boot:

Go to ZCC > Configuration > Preboot Services > Boot Options PXE Kernel Boot Parameters add:   nomodeset

  • Case 3: Add the boot options in the respective configuration files, the configuration files ends with extension *.conf (path for config files in the server: $TFTP_ROOT/efi/x86_64, eg: z_auto.conf,z_maint. conf, z_zpdis.conf ):

append="mode=5 splash=silent showopts vga=0x0314 nomodeset"

Note:  The appropriate configuration file to edit can be identified after the Preboot Options section has completed; e.g.

    • UEFI  (z_maint.conf in this example)

    • BIOS (z_maint.cfg in this example)
