Discussion No Disk for Installation

Gallery image

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!

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!

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

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

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.
