Any help is greatly appreciated.Youre ready to reboot: During the startup of your Mac hold Alt/Option. I have a computer with ubuntu, but need to make a bootable usb FOR A MAC. However, I do not know how to make one in Ubuntu. I KNOW HOW TO MAKE A USB BOOTABLE IN MAC. Anyways, I want a bootable ubuntu usb so I can recover my files/look at the disks. I screwed with some bin files in MAC OSX, and can't log in.Copy the bootX64.efi from ISO-2-USB EFI-Booter for Mac 0.01 beta into /efi/boot on your USB Drive.I did this as an experiment, so I set up the dual boot on an external USB drive. Create the following directories on your USB drive: /efi and /efi/boot. Format a USB drive to provide a single FAT32 partition featuring MBR.A bootable USB drive with Ubuntu on it that work from Windows, Mac OS X. The external USB is 400 GB (this could be far less).Most modern computers can boot from a USB drive, although you may have to. This will launch Apples Startup Manager which shows bootable devices connected to the machine.I’m running a MacBook Pro with 10.5 as the local machine. If you want to use your USB stick with an Apple Mac, you will need to restart or power-on the Mac with the USB stick inserted while the Option/alt key is pressed. By installing ISO image to a bootable USB, you can use GParted clone.Instead, select Eject and remove the USB device. Afterwards, I could boot from the external USB drive, which was a bit slow but definitely useable.Using GParted to Manage Partitions I put Ubuntu on my computer for programming.
Ubuntu Bootable Usb Mac Hold Alt![]() ![]() What you need to do here is “Restore” the install dmg to the first “Install” partition you created above) Click on “Restore” and then “Restore” (I wish I had better notes on this because this doesn’t seem specific enough. Click “Apply” and then “Partition” to formatStep 3 – Setup the Snow Leopard Install (optional if you have an install DVD) Size: 100 GB (all user/personal files will go here, so entirely up to you)The fourth partition is a place holder that the Ubuntu install will format: You will be prompted if you want to transfer existing data. Continue following installation prompts After installation, computer automatically restarts When prompted to select a drive to install to, select your “OSX” partition On the gray boot screen, select the “Install” USB option This way you always specify the boot drive and don’t waste time booting to the wrong drive by accident. Disney magical worlds emulator for macOpen Applications > Utilities > Terminal Boot on the OSX partition and log in as user1 It intentional does some incorrect actions below so you can note the error messages in case you encounter these while trying normal operations. I use “user1” here (you can use any name)OPTIONAL – Test/familiarize with mount and fstabThis section is for education/troubleshooting and can be skipped. Create your user account. To see which drives are mounted, enter:My output is Filesystem 512-blocks Used Available Capacity Mounted on/dev/disk1s3 167772160 19276312 147983848 12% //dev/disk0s2 311909984 308295856 3614128 99% /Volumes/Macintosh HD/dev/disk1s2 16777216 13018432 3758784 78% /Volumes/Install/dev/disk1s4 209715200 124152 209591048 1% /Volumes/DataOur OSX partition (/dev/disk1s3 from the list diskutil output) is mounted as the root at /. We’ll be repeatedly using this “disk1s4” reference note if your Data partition is different and replace in the text below. The Data partition corresponds to /dev/disk1s4. Note the three partitions that we created: Install, OSX and Data. Note that this can be overridden with the -f flag: sudo umount -f /dev/disk1s4If you try “df” again, the data partition is no longer mounted.Note: there are analogous commands such as: sudo umount -f /Volumes/DataThe diskutil command is part of Mac OS X so it will not be on *nix systems. Note that this command requires root permission: sudo umount /dev/disk1s4You may get a “resource busy” error. unmount the Data partition from it’s current location:You should get an “operation not permitted” error. Put a temp file in the Data partition so we can check for it laterTouch /Volumes/Data/this_is_data_partition.txt Here, we are going to practice an intermediate step of mounting it to a new directory called /MyData. (Note: you do not modify the fstab.hd file) sudo touch /etc/fstab The fstab file does not exist under Mac OS X by default, so you may need to create it. You need to tell it to use the Mac HFS partition typeNote: there are analogous commands such as mount -t hfs /dev/disk1s4 /MyDiskDiskutil mount -mountPoint /MyDisk /dev/disk1s4Now we will use fstab to make /MyDisk the default mount point for the Data partition instead of /Volumes/Data. you should get an “Incorrect super block” error. you should get a permission error, so use sudo create the directory where we will mount the partition: ![]() Select Menubar > Format > Make Plain Text (Unclear how to do this? See the optional section above):UUID=1E837B07-01C9-3A9D-384E-6378993848DFF /Users hfs auto,rw 0 0Create a preference file that tells the OS to automount the Data partition even before a user has logged in: Edit fstab to include a line that references your Data partition by UUID and mounts it at /Users like this. Boot to the OSX partition and log in as user1 Rm -f /MyDisk/this_is_data_partition.txtSudo nano /etc/fstab Step 5 – Make OSX use the Data partition for the /Users folder
