Yes that will work for computers with BIOS firmware. For computers with UEFI firmware, you can use wipefs on the EFI system partition, which is typically the first. Confirm with 'blkid' first, and then use 'wipefs -ab' (man wipefs for more info on the options). And then you also need to look at 'efibootmgr -v' and find the boot entry that was pointing to that disk and remove it with 'efibootmgr -b xxxx -B' or you can just leave everything alone and change the boot order to explicitly not use the old boot entry. -- Chris Murphy -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: http://lists.fedoraproject.org/admin/lists/users@lists.fedoraproject.org Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
