BigSur disk doesn't appear after 1st reboot in bootloader

[Moustik2002]

Hi, i hope this is not a dupplicate issue reported there i try to find an answer on my own without any sucessful result.

i'm following tutorial from space invader to create my own bigsur virtual machin through Unraid.

1st try yesterday, i manage to follwo method installation one which lead me to have working catalina instead of bigsur. So i follow the recommendation linked in the issue closed #33

So i manage to remove macinabox and all traces of it thanks to the Bpelech's comment, and redo install w/ method 2

and now i'm stuck here :

instead to have this :

from my research there maybe a link with BigSur-opencore.img wich could be damaged or else.

My question is i would like to be able to download it again but each time i tried, img file is back to isos folder instantely and i've no clue where to clean it up.

Looking to log say : "BigSur-opencore.img already exists. If you want me to replace you will need to manually delete it first" but no still no clue about folder location.

Anyway thx for your soft @SpaceinvaderOne and if you could help me it would be very appreciated !

Moustik !

i'm not sure what's going on with my Big sur install i've tried to delete everything as indicated on spaceinvader video and get a hard reboot issue each time i run macos base system. I've also had an issue when starting VM initially saying "operation failed: unable to find any master var store for loader: /mnt/user/system/custom_ovmf/Macinabox_CODE-pure-efi.fd" than i get ride deleting "custom_ovf folder" before reinstalling macinabox.

In a nutshell i'm completely lost and i need assistance if @SpaceinvaderOne as some spare time to look at my issue.

The same thing happens to me. But I suspect that Apple has changed something. I was able to install Catalina without any problems. After that I did an update to BigSur. Here, too, the error appeared. By the way, the wrong network card is still displayed.

[Moustik2002]

thx for the feedback @SilentBob69 i feel less lonely w/ my issue :)

Just keep choosing MacOS Installer until it is done installing then you should see the disk when it is done with all steps

[Moustik2002]

@plexecutor no MacOS Installer shown on bootloader :

So when i hit enter on it the VM hangs and reboot, no other action available

Hello, If you use the OpenCore iso of the open pull request #47. It boots no problem

[Moustik2002]

@Daandeve sure thing and thx for the guidance. Speaking of guidance i'm not really github fluent could you please tell me how to get opencore.img from the pull request ? Nevermind i finally found it. i Will keep you updated :)

[Daandeve]

Sure, this is the direct link (easier) https://github.com/SpaceinvaderOne/Macinabox/blob/c1d7ecbf4eb01029d98fdda29166391ba5077dc3/bootloader/OpenCore.img.zip You can click download -> extract the iso -> Rename existing (for backup purposes) -> Name the new OpenCore iso the same as the old OpenCore iso Done :)

Note: The OpenCore iso from the pull request is a debug version, it is totally normal to see commands being executed.

[Moustik2002]

Ok done, unfortunatelly VM looping reboot .

When i press enter on the boot loader :

Then it displays this for a moment :

And then back to square 1 :'(

Do i have skipped something ?

[Daandeve]

The steps I described is what worked for me, I did a fresh install of the OS. You should have the disk that you named listed in the boot loader. But on your screenshot is the disk missing. Maybe your install corrupted??

Edit: I think you did something wrong @Moustik2002 when I changed the bootloader the boot loader icon s changed.

[Moustik2002]

ok so i'm gonna try a clean macinabox install but keeping opencore.img somwhere because i giess it will reinstall the non working one instead.

[Moustik2002]

ok, same results w/ clean install Rebooting just after this screenshot; i'm completely lost. Does someone need some logs or else ? I'll be glad to provide if you tell me where to fetch them.

[cracyfloyd]

same here today, i see only macos base system partition. a installation is not possible inside the vm. no gpt partition available.

[Moustik2002]

thx @cracyfloyd i fell a little bit less lonely :)

Tested with BigSur, Catalina & Mojave.

[Moustik2002]

anyone here to support this issue ?

[CanisHelix]

Same as @Moustik2002, stuck in a boot loop with the OpenCore image from the PR. Clean install so nothing previous to mess it up is present.

To all that are having issues with bootloops. Please have a look at this: https://forums.unraid.net/topic/84601-support-spaceinvaderone-macinabox/?do=findComment&comment=1009972

[Moustik2002]

Hey Ghost82 thx for the link to the HUGE thread :) I don't know if you will to continue the discussion here or there, Any way i tried to go back in time and tried the edition of Opencore.img (renamed as BigSur-opencore.img to keep path of ISO in VM conf) you provided and this happens :

modprobe nbd max_part=8

->OK

qemu-nbd --connect=/dev/nbd0 /mnt/user/isos/BigSur-opencore.img WARNING: Image format was not specified for '/mnt/user/isos/BigSur-opencore.img' and probing guessed raw. Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted. Specify the 'raw' format explicitly to remove the restrictions. qemu-nbd: Failed to set NBD socket qemu-nbd: Disconnect client, due to: Failed to read request: Unexpected end-of-file before all bytes were read --> Erf ! OK then let's specify it is RAW !

qemu-nbd --format=raw --connect=/dev/nbd0 /mnt/user/isos/BigSur-opencore.img qemu-nbd: Failed to set NBD socket qemu-nbd: Disconnect client, due to: Failed to read request: Unexpected end-of-file before all bytes were read

--> i guess i'm stuck. I also tried to mount it with windows explorer to see if i'm able to browse inside but with no result (unable to mount the image as well)

Any guess ? .

[82ghost82]

@Moustik2002 I have no issues with:

modprobe nbd max_part=8 cd to/path/where/OpenCore/image/ qemu-nbd --connect=/dev/nbd0 --format=raw OpenCore.img mkdir /mount/point/ mount /dev/nbd0p1 /mount/point/

I think you need to disconnect after you tried to connect without the raw attribute, then reconnect again with raw.

[Moustik2002]

Indeed i didn't know i would have to disconnect it before trying again. So i've good news so far !

Soi've followed the guide line link below but i've added the "qemu-nbd --connect=/dev/nbd0 --format=raw " to the original opencore.img provided by Spaceinvader and edit the script as also described and things seem to be unlocked !

Will let you posted w/ final result ! A huge thx to you @82ghost82 i owe you a beer !

[Moustik2002]

Yeah ! Finally

Just keep choosing MacOS Installer until it is done installing then you should see the disk when it is done with all steps

This worked for me
