Dd Dmg Install It Using

If the DMG was intended to be bootable then the resulting USB will be bootable.

We want to copy a DMG image to a USB drive and keep it as verbatim as computationally possible.

In order to do this, were first going to convert the image to a format thats a little more universal: ISO.

If not, install it using your distributions native package management system.

I used lsblk to figure out how the system was identifying my drive.

Its usually pretty easy to figure out which disk is which based on their size.

This process is going to overwrite the target disk with the contents of our DMG image file.

For example devsdb.

Im using a Kingston DataTraveler DTSE9 and it took about 24 minutes 30 seconds to write 4.9GB.

What I have also noticed is that there seems to be a greater dependency on the various unique IDs used to identify a disk and its components used in High Sierra (APFS or not).

So Ive formatted the SSD after extracting a dump (via dd command and saving the raw image as DMG) from two OSX installations (I had dual boot between Mavericks and High Sierra).

When I received my Macbook back, I could promptly restore the Mavericks installation from the restore disk utility option from the system recovery mode.

However, disk utility seems unable to restore the High Sierra partition.

The DMG raw image can be mounted flawlessly from a High Sierra install, Im just unable to move that to the SSD.

Any ideas.

Have you tried reversing the if and of parameters from the dd command you used to create the image (You can use Mavericks or the Terminal in Recovery - unmount the APFS partition before restoring.).

Did you erase the SSD prior to service for privacy and are now restoring it Did you just erase the partitions but kept the original partition table.

Ive actually erased everything, that is, all the SSD was set as free space.

The images were created through dd ifdevdisk X s Y ofVolumesExternalDriveHighSierra.dmg or something alike.

Ive already tried restoring through dd command, but it seems that it created a corrupted partition.

I looked at the developer betas of Mojave that still seems to be the case.

In testing Ive done, while doing intelligent copying of files from a system disk to another disk (intelligent being taking into account links, special device files, etc.) used to produce a working, bootable clone up to Sierra, thats no longer the case with High Sierra in some instances - and it doesnt matter if its APFS or not.

So what Im wondering (and I dont know if Apple has disclosed this or not) is whether or not to restore a dd-produced image of a APFS partition (container) requires that you restore to a partition that has the same Partition UUID (and thats why I asked if you still retained the partition table).

In the normal nix world, typically what youve done should work.

You should make sure, to the best extent possible, that your disk is partitioned exactly the same as it was before.

If that is the case and its still not working, I think you should call Apple and ask for advice (of course you can search the web as well).

What I have noticed, and others have noticed as well, certain disk imaging functions dont work with regards to APFS containersvolumes in Disk Utility.
