I have moved entire partitions , lengthen partitions, shrunk partitions, all without having lost anything. I've used it on just about every type of file system except BTRFS. It's always a very nerve wracking adventure. I always take backups. It's never failed me. I always download the newest gpartd Bootable disk rather than using what came with opensuse. Just a Habit. Assurance you ask? Good chance of success with the move. Slim to zero chance of anyone giving you assurance. -- Sent from my Android phone with K-9 Mail.

I recently did something similar on laptop (though non-EFI). The first partition was "/boot" (taken over from the Dell OEM partition). I wanted to enlarge it, so I tried to move everything down a little keeping the same sizes. Note that I had deleted all other linux partitions, prior to installing 13.2, so this was mainly a Windows move. Windows (Win7) complained, though it claimed to have repaired the problems. I then tried plan B: I restored the Windows partitions from an Acronis image backup that I made before starting. Windows was much happier. In your case, with a FAT partition, you are less likely to have problems. But take a backup first. In a reply, Carlos wrote:

The problem is that UEFI booting menu is based on partition and file system UUID, and a backup-recreate-restore will change those. So the boot entries probably need to be recreated. My choice would be the move/shrink, with a re-create/restore alternative if something goes wrong. In case you have to regenerate the MVRAM entries for booting, it is possibly enough to get opensuse working. Then run grub2-mkconfig to regenerate the grub2-efi boot menu, which should have an entry to boot Windows. When you next boot Windows it will fix its own boot entry (and make that the default for booting). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

(U)EFI boot partions are (V)FAT32 formatted. Just the partition-type-id is different from standard FAT. And yes, in case of EFI boot partions, shrink + move is much easier than delete and recreate. Stupid uuid. This reflects some ugly lessions from RL. Leaving an empty space (multiple of 4k) up to a full 1024kB = 1MB makes sense. That way no bootloader will shredder the first partition.

# blkid /dev/sda1 /dev/sda1: LABEL="BOOT" UUID="f7e3ef67-a45c-4562-b404-5c48a2e3d2f2" TYPE="ext2" PTTYPE="dos" PARTLABEL="primary" PARTUUID="cebb3ec5-8cfe-4272-954e-04552ca5305c"

Things I don't know.

* why, even though it *IS* labelled "BOOT" its not so for "fdisk -l"

The label is stored inside the filesystem, fdisk does not look inside the content of the partition, and thus can not see the label.

...

* The difference betwewnn a UUID and PARTUUID

The PARTUUID is given/assigned by fdisk/parted at the time the partition is created. The UUID is the filesystem uuid, and is given/assigned by mkfs.xyz at the time the partition is formatted.

...

* Why the PTTYPE says "dos" when this a "gpt" device as reported by fdisk

PTTYPE is partition table type. Available are: * MBR only, old style, called "dos", limits are known (2TB) * GPT only, new style, called "gpt", some tools can't handle it. * GPT with "protective" MBR, this COULD be misdetected as mbr only if less than 15 partions are in use, and the tools aren't careful. Still, the sentence about space BEFORE the first partition still applies, no matter what type the first partition filesystem is. This one megabyte is NOT wasted. Just one bootloader fuck-up, and you will be happy about that space.

Because in fdisk you can edit the type; this is different than the label or the filesystem type. Linux does not use the partition type, it is informative. Those types were limited in MBR partitions to 255 types (a byte). Linux used types 82 and 83.

...

* The difference betwewnn a UUID and PARTUUID

The former is stored inside the partition. The later is stored in the partition table, /if/ it is GPT. - -- Cheers / Saludos, Carlos E. R.

Because in the partition layout it is marked as "EFI", and those are always FAT.

That's because your output listed it as an EFI system partition. In your case, that's an installer bug (bug 934309). I suggest that you use "gdisk" to change the partition type code from EF00 to 8300. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ok, right. There are two ways to sort that out: edit fstab and grub to reflect the new uuids (if used; I use labels instead). Or, edit the partition uuid to be the same as it was.

Neil spoke about UEFI menu, not fstab or grub. Partition signature is part of device path used by UEFI to access executable; in case of GPT partition signature is unique partition GUID that is expected to be unique for every single partition ever created (not to be confused with partition *type* GUID). Recreating partition changes GUID. It is possible to rewrite it using e.g. gdisk "c" command to restore to previous value - if you saved it before :) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlWPkaAACgkQR6LMutpd94w/wQCfQXTNhxcv54/GFfWG7q5coEvv KygAn1Vfnp+qUpjg98U76FN97G6fOCmF =dReQ -----END PGP SIGNATURE----- N��r��y隊Z)z{.�ﮞ˛��m�)z{.��+�:�{Zr�az�'z��j)h��Ǿ� ޮ�^�ˬz��
