how to remove bootloader
I have a pc which initially had a single drive with F23 installed on it, running perfectly. Now I just added a second drive and I installed again F23 on it, with the intent of using the first drive for data only. So now I have two perfectly good F23s installed on separate drives and I can boot either one of them. I want to 1) remove the bootloader from the first disk 2) reformat the system partitions on the first disk 3) keep and expand the data partitions from the first disk I know how to do 2 and 3, but I need to know how to do 1 without losing the partition table. The reason I need to remove the bootloader is that by default, the pc boots from the first drive. I can display the boot order (F12) and select the 2nd drive manually upon boot, and I can also probably change the boot order in the bios, but I recon there must be a software way to remove the bootloader. Does anybody know how to do this?

Of course that may entail fiddling with grub so drive 2 is drive 1, so to speak. An alternative is to leave the bootloader as it is, use it to boot the second drive with the OS, and simply use the rest of that drive for your data, etc. Proportionally speaking, the boot partition ought to small enough to not worry too much over. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.

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 -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?

I found the magic too not long after I posted. I wanted to know the exact size I had to zero out without touching the partition table. -- 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?

No, I don't want to do that because each drive is in fact a raid array with two physical disks each and I don't know what the raid controller would do if I swap the disks. -- 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?

Though I imagine it would do the same as using the BIOS options to boot from a different disc (as mentioned earlier). But I see you've found a path to follow, in another message in this thread. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.

FYI, gmail puts your emails in spam for the following reason: Why is this message in Spam? It has a from address in yahoo.com.au but has failed yahoo.com.au's required tests for authentication. I'm seeing an increase in list emails dumped into spam with the same kind of message. I'm not sure what's failed, this is the best clue I have: Received-SPF: pass (google.com: domain of users-boun...@lists.fedoraproject.org designates 209.132.181.2 as permitted sender) client-ip=209.132.181.2; Authentication-Results: mx.google.com; spf=pass (google.com: domain of users-boun...@lists.fedoraproject.org designates 209.132.181.2 as permitted sender) smtp.mailfrom=users-boun...@lists.fedoraproject.org; dmarc=fail (p=REJECT dis=NONE) header.from=yahoo.com.au Anyway, maybe it's worth a separate thread instead of hijacking this one... -- 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?
