In attempting to arrange dual-booted linux on my c. 2014 period macbook, I corrupted my set up of macOs Monterey to an unbootable state. Booting to web restoration mode, I tried to make use of the primary help device to restore the disk, which recognized that the disk was not bootable, however didn’t restore it. After operating gpt -r present disk1 within the terminal, I noticed that disk1s2 had modified to FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF.
Utilizing that identifier as a keyphrase, I discovered [this ask different forum post] and adopted the steps. Nonetheless, I didn’t obtain an output from dd if=/dev/disk0s2 rely=3 | vis -c that gave the impression to be something just like the supplied pattern strings for both a typical or a CoreStorage partition.
Regardless, I continued following the steps, unmounting my drive and eradicating the third, 4th and 2nd partitions. When trying to re-add the partitions, I first used the sort and index quantity supplied for the traditional OSX partition, which returned an error of not sufficient area. I proceeded to attempt the index numbers for the opposite two partition tpyes listed, each of which returned the identical error.
I got here to comprehend that relying on the particular partition and MacOS model, that the index varieties and numbers range largely, and I assume that I might have the ability to get the precise data I wanted from discussion board posts, nevertheless my very own makes an attempt to seek out this data from different sources had been unsuccessful.
It was at this level I allowed an acquaintance who had expertise in laptop computer restore to take over. They proceeded to restart the macbook and tried web restoration, to the identical success that I had discovered when trying the identical method.
This detour not solely cleared the terminal and all of the logs I had not had the presence to correctly doc, however upon re-running gpt -r present disk1 partitions 2 and 4 had been each gone.
Utilizing this discussion board publish I tried to get the gdisk command to repair the GUID Partition Desk. The script supplied initialized, however no information was transferred, regardless of a sound web connection. I tried to obtain the device with out utilizing the script utilizing the listing of instructions supplied in a while, to the same lack of success.
Is it nonetheless doable to get MacOS to a bootable state with out dropping any of the recordsdata I’ve saved? (assuming that re-starting mid-repartitioning did not wipe all the things)
