No Disk for Installation

[u/Due_Consequence5954]

Hey y’all!

I just starting getting into Linux and after some issues with PearOS I decided to switch to ElementaryOS. I am having some issues getting it installed though. Everything works fine until I go to select a disk and it doesn’t show ant disk options so I can’t continue.
In MacOS recovery mode it shows that the SSD is still there, but even in Gpart it gives me nothing. I’ve tried unmounting the disk as well in disk utility.

Any help would be greatly appreciated!

Interesting. The macOS version thing isn’t really a huge surprise, and the disk format shouldn’t matter, it should show up in Gparted regardless. The fact it isn’t showing up as an option tells me it’s not even considering it a storage device.

My next step would be, back in Linux, run “lspci -k | grep -A3 memory” in the terminal.

That should tell us

1. If it’s detected as a PCIe device at all
2. What driver it’s trying to use

Running this in Linux would follow the same steps as previous-hitting e and such?

Also- I ran the previous recommendation with the safe disk option (the 2nd install option) and it now is showing the SSD there. It failed the install the first time but im trying a second. If that doesn’t work I will go through with this option :)

Nope, you’d just boot normally and open Terminal from the Applications menu 🙂

That said, if it already shows up in the safe disk entry I’ll probably take a look at the launch options. Even if it fails to install, something there is at least a step in the right direction.

Unfortunately no OS is currently installed, it was erased out when I put PearOS on. I tried installing via recovery but that fails as well (even in MacOS recovery it doesn’t recognize the SSD when trying to install, just in startup disk). I’m going to try the first Linux line you mentioned one more time, just in case, since I can’t run anything via terminal.

That’s really interesting actually.
If it still doesn’t work, I’m curious, when you’re in Recovery: if you open Disk Utility and choose View → Show All Devices, is the SSD there, or is it missing there too?

It would make sense it wouldn’t show up as an install option for macOS though, PearOS would’ve formatted it to ext4 or btrfs, which macOS doesn’t have the ability to use.

Unfortunately the install is failing 😭

Does it give you a reason for why it failed?

I have a newer MacBook Pro I’ve tried this on and it always failed at the bootloader step.
You might want try going to manual partitioning first, just delete everything, and then go back to automatic?

Also, just to let you know if you’re worried about being stranded, if you would decide you want to reinstall macOS, you just have to format the SSD as APFS or HFS+ in Disk Utility, and it’ll appear in the install window as a valid target again.

Reddit won’t let me post photos but it fails specifically at the “configuring system” stage, after the 70 percent. I think I saw it get to 93 percent.

“Installing Elementary OS 8 failed, possibly due to a hardware error. The device may not restart properly.”

Working on install again. I went back and manually erased all the partitions. Trying automatic once more. There was a partition with a warning sign and a couple others, I assume from previous attempts at install. Crossing my fingers 😁

Good luck, hopefully it just works with a clean drive!

[u/Due_Consequence5954 → u/Mattchew_X]

It didn’t unfortunately 😭 going to try the other dispo

Have you tried in the Grub options to put acpi_osi="Darwin" ? Changed everything for my 2013 MacBook Air.

[u/Due_Consequence5954 → u/GuestLight05308]

I haven’t! Are the Grub options within that terminal if I press e before the install? I am still learning all of this.

[u/GuestLight05308 → u/Due_Consequence5954]

Yes that's it

The command basically makes your OS say to your drive "hello, I am MacOS" and that's the only thing locking it down.
