This post may only be suitable for technical brothers, or you want a USB that contains everything in the world, can Boot to rescue on Win, install Windows, Have some macOS installers available to install Mac … In this article, I will guide in the most detailed way possible so that anyone who does not know very well can create a USB as you like.
In order for the post not to be long, I will also enter the post.
* NECESSARY TOOLS
1. Carbon Copy Cloner: Can download the version suitable for macOS version or download the latest version at Carbon Copy Cloner 6.x
2. Download and unpack the Anhdv Boot set repackaged with Carbon Copy Clonner here: Anhdv Boot
3. The necessary macOS installers for example: Monterey, Big Sur, Catalina … here: MacOS installer
4. 01 USB has as much capacity as possible. With the Boot Rescue Boot partition on Windows side about 3GB then:
With 32GB: It is possible to create an additional macOS installer with a small partition containing DATA (ISO file install Win, some necessary software …) or if skillful, insert 2 macOS installers just add 2 macOS installers
With 64GB USB: About 4 more macOS installers can be created: Monterey, BigSur, Catalina, Mojave and a little extra to store DATA. Whoever creates fewer installers, the extra partition contains more DATA.
With 128GB USB: This is comfortable, all the installers if you like and some basic software
Advice: The most optimal is probably 64GB USB, which can contain 2 latest macOS installers + 1 Boot partition on the Windows side + 1 DATA partition to contain ISO files to install Win, the necessary software…. Of course, with the budget, playing 128GB USB is much better.
* STEPS TAKEN
Here I guide based on 1 USB 64GB, other USB space you do the same (read carefully understand the principle)
Step 1: Plug in USB, open Disk Utility up (Don’t ask anywhere to open disk utility, if this also asks, it will not be possible to do it again)
Step 2: Erase USB according to the instructions in the following image: (Pictured below is I sacrificed Erase the USB Boot is using well to serve as a guide)
– (1): Click on View> Select Show All Device (2): Select the USB name (highest item) (3): Press Erase
Name: To default: Untitled
Format: macOS Extended (Journaled)
Scheme: GUID Partition Map (if you don’t see the Scheme, read it carefully above)
Step 3: Divide partitions depending on needs:
This step depends on how many GB of USB, how many installers you want to create that you divide accordingly. To divide you press back on your name USB>Create Paratition
Press the mark + then drag the slider back and forth (or type the capacity into the Size cell) to divide it into the appropriate partitions. The experience for you to refer to is as follows:
macOS Monterey: About 14.5GB
macOS Big Sur: It’s about 14.5GB, it’s probably every 15GB.
Catalina: About 10GB is enough.
For example, in the picture I divide partition number 1 and number 2 to create an installer Monterey and BigSurPartition number 3 About 3GB to give. Anhdvboot enter. Partition number 4 it will be partition. DATA to contain other necessary software.
Step 4: Zoning Erase 3GB expensive FAT32
Partition No. 3 about 3GB above needs to switch to FAT32 to be bootable on Windows. To erase, you continue to open. Disk Utility, select the 3GB partition. Then select Erase. The Format cell selects MS-DOS(FAT) as shown above.
Step 5: Use Carbon Copy Cloner to Restore Anhdvboot to 3GB partition
– Of course, you must install Carbon Copy Clonner first, the step of installing does not write here to help the long post.
Open carbon copy clonner. Select as picture
Note: The download anhdvboot file is a compressed file, you have to unpack, then item 1 is to select the unzied anhdvboot folder, not to select the compressed file. When you press Start it has a message, select Continue Anyway
Wait for carbon copy Clonner to complete, you can change the untiled partition to the other 3 BOOTWIN Something beautiful depends.
Step 6: Create a macOS installer into the remaining partitions
To avoid stretching, you read how to use the command to create a macOS installer here. Flexible application to create installer into each partition on USB
Detailed instructions for creating a macOS installer using Terminal
For those of you who don’t know, read this post. I write too many details of brothers full of long coal leading to laziness to read 🙁
How to create multiple macOS installers on 1 USB
Step 7: Erase partition remaining is not used to create macOS into ExFAT format so that it can contain DATA Otherwise, it can be used both on Win and Mac
Note: USB after creating partitions with macOS installers will not be read on Win, plug in will require Format, you just need to close to ignore. BOOTWIN partitions and DATA partitions are finally readable normally.
