Ubunto Boot For Mac Files
The -R is there to recursively change permissions on everything contained within Music. You would use 755 if you are fine just accessing Music, but didn't want to be able to add or delete files to the Music directory from Ubuntu.
Ubunto Boot For Mac Files
On my Mac OSX Mojave machine.. I installed Ubuntu 18.04 to attempt to dual boot on the internal Apple SSD. Worked for a while, but after some updates to Ubuntu... hitting the power button boots up to a GRUB terminal, and when hitting the option key there is no 'Macintosh HD' as a startup option.
What can I do to make it so that I can fix my OSX boot partition without losing any files. The disk that my OSX files are stored are on disk0s2, which is the FFFFFFF partition... how do I fix up my ability to boot into the OSX Mojave without wiping out my data or is there a way? Does APFS have anything to do with this?
The EFI partition (disk0s1) is used occasionally by macOS, so you need to keep this partition. However, Grub files were added to this partition when you installed Ubuntu. The commands below will remove any Grub files that may still exist on the EFI partition . You can enter these commands while booted to macOS.
Since the free space occurs immediately after the partition identified as disk0s2, this free space can be added back to macOS. To add the free space back to macOS , enter the command given below. You can enter this command while booted to macOS.
If you have or can make the Ubuntu Live USB flash drive installer, then you can boot to the Live version to fix your Mac. Usually when the FFFFFFFF-FFFF-FFFF-FFFFFFFFFFFF error occurs, the partition starting and ending values are still correct. I assume this is true in your case. If I am correct, then you can implement the following steps to change the partition type from FFFFFFFF-FFFF-FFFF-FFFFFFFFFFFF to 7C3457EF-0000-11AA-AA11-00306543ECAC.
Since the free space occurs immediately after the partition identified as disk0s2, this free space can be added back to macOS. To add the free space back to macOS, enter the command given below. You can enter this command while booted to macOS.
This guide will show you, step by step, how to install a full version of bootable Ubuntu on a SSD (solid state drive, or any other external drive), using only your Macbook. We will generally be following these instructions, with a few key modifications.
When I installed Ubuntu Saucy (13.10), I was initially faced with an unbootablesystem, which I eventually got to work. When Ubunty Trusty (14.04) came out Iwas hoping things would go better. Sure enough, there was a +mac variantinstaller available (buried behind several download pages), but ths used legacyBIOS booting. The non +mac variant simply gave me an unbootable system again.
If you see any partition labelled anything like BIOS legacy boot orbios-grub, you might have missed a vital part of these instructions and areusing the +mac variant of the installer.
Because I was doing this over and over again, I occasionally encountered aproblem where the installer would be unable to format the EFIboot partition. Ifthis happens, try zeroing the drive and start over.
For system partitions (eg. /, /boot, /boot/efi) Ubuntu uses the UUID(universally unique identifier) of a disk partition to mount it (rather thanthe device node, eg. /dev/sda1). This means we need to update /etc/fstab:
First, you must create a bootable USB using the Ubuntu ISO or setup file. Second, you must boot from the USB and install Ubuntu on that computer. This way, you will be able to download Ubuntu from USB.
Running boot from USB Ubuntu is a seamless process that can be quickly done without hassle. The best thing here is that one doesn't necessarily need technical skills to initiate booting. The Ubuntu USB includes all the essential files, including system booting information.
USB Ubuntu offers users an easier way to boot up their devices effortlessly. The best thing here is that one doesn't need to install Ubuntu on any device. Connect the USB Ubuntu to your device and start the booting process within a few clicks. The things you have to do here are:
Step 3: Launch the application, automatically detecting the ISO file once you find it. It will also automatically detect the USB drive. Select the one you want to make a bootable disk if you have multiple disks.
Step 4: Click on the Make Startup Disk, and then it will ask for confirmation. Once you do that, the writing process will start, and you should see the progress bar. Once complete, you will have Ubuntu on a USB stick, bootable and ready to go.
Step 4: If not, go to the Boot Menu or BIOS/UEFI option and launch it. Keep the device connected, and press the F2, Del, or ESC key to boot into the BIOS or UEFI. The information should be available when the PC boots up.
Booting from USB Ubuntu is one of the easiest and quickest ways to boot up a computer system. The process brings up a lot of benefits along with it; if you are eager to know, check the few we are providing you below:
Hopefully, you have gotten to know how to boot from USB Ubuntu conveniently. It is an easy and quick process that hardly requires a few clicks to make it. One can now quickly test the USB user experience and even boot Ubuntu on a borrowed machine or internet cafe without any issues. We have provided you with a detailed step-by-step process for booting from USB Ubuntu. Follow up on the given process carefully to enjoy seamless access.
Although we have enlisted all the required details above for booting from USB Ubuntu still, there are some mostly asked queries that we would like to solve here. It will not only add up more to your knowledge hub but also will ease things up more for you.
Many computers these days come with two hard drives, one SSD for fast boot speeds, and one that can be used for storage. My Dell G5 gaming laptop is a great example with a 128GB NAND SSD and a 1TB SSD. When building out a Linux installation I have a few options. Option 1: Follow the steps and install Ubuntu on one SSD hard drive for quick boot times and better speed performance when opening files or moving data. Then mounting the second drive and copying files to it when I want to backup files or need to move files off the first drive. Or, Option 2: install Ubuntu on an older hard drive with more storage but slower start up speeds and use the 128GB as a small mount point.
This guide can also be used for other use cases as well. An example would be old or cheaper laptops that don't have hard drives with high RPM spinning SSDs. If your computer is a bit on the older side (and has an SD card slot) but you want to utilize faster boot times, you can go out and buy an SD card and install the /root partition onto that for quick boot times, and the /home partition on the main drive for storage. This guide, like Linux, can be used for many other use cases as well.
In this guide we will start by downloading the latest version of Ubuntu Linux, our distro of choice. You can choose other distros, but the images and steps may vary. The Ubuntu version at the time of this guide is 20.04.1. Once you have the ISO file downloaded you can then download the Etcher USB imaging tool. I have found this to be the quickest and most straightforward easy-to-use tool for creating bootable USB images on any operating system.
If your PC does not support booting from USB, burn the Ubuntu iso image to a DVD. and change the boot order to boot from CD/DVD first. Once we finish the installation you should change the boot order to boot into the SSD hard drive.
For the second drive select /home as the mount point. This will allows your home folder to be set on the 1TB hard drive. You will be able to install Steam and download games, or download files and documents from the internet and have it go to your downloads folder without having to worry about setting up different drive or pointing to a new folder. You have 1TB of space to play around with.
The installation process from here is the standard installation. Select a time zone, create a username, computer host name, create a password. Once completed, you're all set. You can remove the USB thumb drive and reboot your machine when prompted.
I know this is a super common issue, but if I am here it means I have already searched and tried many roads: unsuccessfully. I am trying to install Ubuntu on a MacBookPro 13" 2019, running MacOS BigSur, in a partition (nor VM nor bootcamp).
From my research I found that the issue is due to the Mac bootloader expecting the EFI partition to be formatted as HFS+ where the Ubuntu installer formats it as VFAT (as stated by Rohith Madhavan here).
Confirm that the UUID you received from before is located in your distribution's grub.cfg under /boot/efi/EFI/ (ex. /boot/efi/EFI/ubuntu/grub.cfg) in the line search.fs_uuid SYSTEM-PARTITION-UUID-HERE root. If not, copy-paste the line with the current value and prepend with a comment line (#), and on your new line, replace the SYSTEM-PARTITION-UUID-HERE with your UUID of your ubuntu partition.
Here you want do reformat the VFAT boot loader that the Ubuntu installation made by default to HFS+. This can be done by making your own boot loader config using GRUB. The method I used was the same as what Floris van Breugel did (but on my internal SSD instead of an external SSD).
How come I'm allowed to reboot a computer that I don't own, put in a USB, boot ubuntu from it and then access all files stored on the drives available (even critical files such as system files on C drive in Windows)?
