Require help to multiboot MacOS

4 posts in this topic

Recommended Posts

Hey everyone! I'm new to the forums and I've been browsing around. I want to easily install a Mac OS alongside my Linux / Windows 10 dual boot. I have my Windows on a SSD and my Linus on a separate HDD, any way I can easily shrink my HDD and put MacOS on it, and have it not effect my Windows? I also want to know the best Mac version I can use since I'm unsure if my GPU is supported.

 

CPU - i7-6700K 

GPU - Aorus RTX 2080 Ti

MB - Asus Z270-A

RAM - 32 GB

 

Please let me know if there is a way to easily install MacOS, wish it was simpler like Linux.

Although doable I would strongly advise anyone doing a dual or triple boot, to put all Operating Systems on separate drives (The cost of drives are pennies these days). That way minimises potential cross Data corruption or confusion in future updates/upgrades. Not completely sure but your GPU is not supported by Mac.

Indeed, no support whatsoever for Turing cards. Only the HD530 iGPU could be supported and in all recent versions of macOS.

 

Shrinking the partition of one of your existing drives could indeed be the way to go. I've done it myself on the SSD of one of my Dell laptops because it only supports 1 x disk, so I had no other choice. You can of course install the Hackintosh bootloader (say Clover for instance) on the selected disk in order to support multiple boot. Plenty of tutos on this matter.

 

If you are reluctant to do that for fear of losing access to the existing partition, you may opt for the alternative of installing and therefore booting the Bootloader from a separate media provided it's bootable (USB key, SD card, etc). That's what I do on my laptop, having installed Clover on a SD card to avoid potential messing of the Windows boot partition (I use the laptop for work).

 

Whatever you do and before anything else, make sure to make a copy of the existing partition of the disk you select (eg: clone or image) so that you may recover in the event of a major f u c k -up.

You could shrink the partition of your linux drive I guess, format it as free space or FAT32 or somthing the OSX installer knows how to deal with. Before you do ANYTHING though, make a full backup of the disk youre going to be messing with, just use dd and output it to an .iso file stored somwhere else, that way you can just restore it exactly as it was before you started. If you do that first, you should feel totally comfortable to start trying/breaking things and seeing whats possible, and just do a full disk restore if you want to start over.

 

dd if=/dev/sdX of=/A-NAS/A-FOLDER/linuxhddclone.iso conv=sync,noerror,bs=4m
