    I just received my new 2017 high end imac with 2tb fusion drive and tried to restore from a time machine backup, during restore the imac crashed. I tried to restore the OS but it now cant find the internal hdd to install ths OS.

    Has anybody had the same?

    If the drive isn't appearing it may need to be reformatted/erased. Once the restore os boots up there will be a Utilities menu where you can choose disk utility then select the disk in there and "Erase it" which should make it show back up during the installing wizard.

    Hi, not sure what is wrong but received a new Imac and tried to restore again and same thing, it crashed and now can find internal hard drive, I am using high sierra beta, could that be an issue or time machine be an issue?

    Can you please tell me how i reformat using disk utility and fuse the ssd and hdd again?

    Are you saying that you're using the High Sierra beta but you don't know how to troubleshoot an OS install issue?

    Think the problem is the drive is formatted APFS for H.S. beta and the external is still HFS and the two don't go together. Download (if you can) Sierra and just clean install that.

    Surely you only did this on a partition and not as the only operating system? If not you asked for troubles.

    So after formatting both drives and then fusing them together again, I installed Sierra on to the formatted drive and did restore from Time machine again and it worked this time.
