You can also bring-your-own (BYO) custom VM image to use instead.\nThis document provides information on GDC-provided and\nGDC-supported VM images, as well as instructions to view\nthis list in your GDC air-gapped appliance deployment.\n\nBefore you begin\n----------------\n\nTo get the permissions you need to list and use Google Distributed Cloud air-gapped appliance VM golden images,\nask your Project IAM Admin to grant you the Project VirtualMachine Admin\n(`project-vm-admin`) role in the namespace where the VM resides. Follow the\nsteps to [verify](/distributed-cloud/hosted/docs/latest/appliance/application/ao-user/vms/preparation#verify-user-access)\nthat you have the required permissions.\n\nList VM images\n--------------\n\nThis section provides information about GDC-supported\noperating systems.\n\n### List golden images\n\nBefore you create a VM using a GDC-provided image,\nreview the list of available images. Refer to the instructions in\n[View a list of available GDC-provided images](/distributed-cloud/hosted/docs/latest/appliance/application/ao-user/vms/create-a-vm/create-and-start#view-list-images-available).\n\n### List BYO images\n\nYou can also use your own custom images to create VM instances. This is useful\nwhen you have specific operating system or software configurations that you must\nuse. To create and list BYO images, refer to the instructions in\n[Create custom images](/distributed-cloud/hosted/docs/latest/appliance/application/ao-user/vms/create-custom-images/create-custom-images).\n\nGDC-supported operating systems\n-------------------------------\n\nThis section details the operating systems GDC air-gapped appliance VMs support.\n\n### Linux OS\n\nGDC air-gapped appliance supports the following Linux OS images:\n\nYou can only import Linux images from bootable disks. To boot your virtual disks\nin GDC air-gapped appliance, the disks must run one of the\nGDC-supported operating systems.\n\n### Windows OS\n\nGDC air-gapped appliance supports the following Windows OS images:\n\nYou can import Windows images from ISO installation media. GDC air-gapped appliance\ninstalls Windows and creates a bootable image from the resulting disk.\n\nImage import requires that the ISO does not prompt for input when booted with\nUnified Extensible Firmware Interface (UEFI). To create a no-prompt ISO, start\nfrom an existing ISO file. Complete the following steps:\n\n1. Extract the ISO contents using the 7Zip archive management tool:\n\n 7z x windows-installation.iso -oiso-unpack\n\n2. Create a new ISO from your extracted ISO using `mkisofs`, substituting in the EFI noprompt\n binary:\n\n mkisofs -b boot/etfsboot.com -no-emul-boot -c BOOT.CAT -iso-level 4 -J -l -D -N -joliet-long -relaxed-filenames -v -V \"Custom\" -udf -boot-info-table -eltorito-alt-boot -eltorito-boot efi/microsoft/boot/efisys_noprompt.bin -no-emul-boot -o \u003cvar translate=\"no\"\u003eISO_NAME\u003c/var\u003e.iso -allow-limited-size iso-unpack\n\n Replace \u003cvar translate=\"no\"\u003eISO_NAME\u003c/var\u003e with a name for the no-prompt ISO. For example, `noprompt-install`.\n\n| **Note:** Image import is only verified on official Microsoft installation media. Other installation ISO files might work if they contain a gdc-provided Windows OS."]]
