It's not really reducible to which utility you use. Both fdisk and parted can create ms-dos or gpt disk labels. If you want to pre-create a layout for a UEFI install, just make sure you use a gpt one. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- test mailing list [email protected] To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
