Make Osx Boot Usb

  



I have a 2020 HP laptop. Windows 10 UEFI I installed some apps and my personal stuff and then cloned the drive .
I decided to check out Ubuntu, But being i didn't have enough room on the hard drive, I burned the install onto a USB stick and installed 18.04 to another USB stick. All is well and with an F9 at boot up I could boot from the Ubuntu USB install.. got it personalized and added a few apps ect. One recovery app that was a one time only install that I paid money for. R-Studio for Lunux.
Next my Windows hard drive gets corrupted. I can still boot Ubuntu UEFI but not windows. Only the windows partition got corrupted. I used r-Studio for lunux and it recovered some of the stuff and windows still won't boot.
So rather than corrupt that drive as there is still stuff in there, I cloned the orginal drive with JUST WINDOWS 10 ON IT and installed the clone. The boot manager now knows nothIng about Ubuntu. How can I get the UEFI boot menu to see the ubuntu USB pen drive? It will boot if I turn off secure boot and turn on legacy support, but I really would like it back the way it was. It will also boot to Ubuntu using the Dead windows drive that at one time had Ubuntu UEFI on it.
My thoughts.. Install ubuntu 18.04 (can I use 20.04 install instead) on another USB stick. That should add the UEFI UBUNTU to the boot manager menu and then just go back to using the old stick of the same size and brand. Will that work
Is it possible to manually edit the windows UEFI boot manager to add Ubuntu to boot the stick manually?
Cronologically
1. Bought new laptop January of 2020 HP Pavilion 15 500gb NVME
2. Installed 'MY STUFF' on it
3. Cloned the Drive to make a backup in March
4. Decided to Install ubuntu 18.04 on USB stick from another USB stick All working OK. can F9 on boot and can see in boot options UEFI windows and UEFI Ubuntu. Both boot fine, Ubuntu runs off of a 64gb usb stick
5. Windows partition crashes/gets corrupted won't boot. Ubuntu stick will still boot fine using F9 and selecting Ubuntu
6. I purchase R-Studio for Lunux a one time install app, and recover as much as I can, not all. windows still wont boot, about 25% is unrecoverable with R-Studio
7. I purchase an NVME external usb drive case and install the 'dead' drive to play with it later.
8. I have a 2 TB NVME drive and cloned the backup to it, and now am back to where I was in march . missing apps, pix ect AND THE UEFI ENTRY FOR UBUNTU
9. If I plug in the Crashed drive, the UEFI menus come up for Windows and Ubuntu. If I select ubuntu . it boots up and I can remove that drive.
10. I had to turn off secure boot to boot just off of the ubuntu USB stick, but it works.
11. Windows works, Ubuntu boots up and am trying to recover all the stuff that accumulated in the last year. Partly successful
12. If I turn the secure boot back on, I cannot boot Ubuntu from the stick. That's what I want back Can this be manually edited somehow?
My plan
with another 64gb USB stick of the same brand, install Ubuntu 18.04 to that, and have it update the windows UEFI boot manager. Shut down and put in the other stick, but will it boot up? If there is a way to manually update the boot mgr or even copy files from the 'dead' windows boot partition, which is intact.
anybody else have 'A PLAN' of action

If you’re still using a Mac OS X the time will come when your computer won’t boot, or a problem may arise where you can’t take control of the device, and booting from an OS X installation media will be required.

This is why it’s recommended that you make a Mac OS X bootable USB when your Mac is in working conditions. However, if you find yourself on a scenario where your device (iMac, MacBook Pro, Air, Mac Pro or Mini) is not responding and you happen to have a Windows 10 device, then you can still be able to make a USB bootable installation media for your Mac OS X to reinstall the operating system using the Recovery Assistant.

These instructions will also work for Windows users who are running Mac OS X on a virtual machine and need to upgrade to the latest version. For instance, to OS X Yosemite.

Much like prior versions of Mac OS, you can easily create a bootable install drive for MacOS Mojave 10.14. These boot install drives allow for things like easily formatting a Mac to perform a clean install of macOS Mojave, installing macOS Mojave onto multiple Macs without them each having to download the installer, or even as a troubleshooting tool since it can be booted from by any. Installations of other versions of Mac OS or OSX (roughly) follow the same path. NOTE: When trying to install Mac OS 9.0.4 you need to make sure to use a version that contains a Mac OS ROM version 5.6 or above. Also make sure to set the -M parameter to -M mac99. If you need to boot from a real CD, see the section Booting from a real CD below.

Requirements

Boot Usb Windows 7

Before you dive into this guide, you’ll need a few things:

  • A broken Mac computer with Mac OS X.
  • A trial copy of the TransMac software.
  • One high quality USB flash drive with 16GB of storage.
  • A copy of Apple’s macOS (DMG file).

Now that you have all the necessary ingredients, you’re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below.

Create Mac OS X bootable USB installation media

Before you can use TransMac, you first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows 10.

Setting up GPT partition

Use these steps to set up a USB drive with a GPT partition: Macbook pro mid 2012 latest os x 10.8.

  1. Open Start on Windows 10.

  2. Search for Command Prompt, right-click the top result and select the Run as Administrator option.

  3. Type the following command to open Diskpart and press Enter:

  4. Type the following command to determine the USB flash drive and press Enter:

  5. Type the following command to select the storage and press Enter:

    Quick tip: The select disk 1 command as an example, but you have to replace 1 with the number of the flash drive you want to use.

  6. Type the following commands to delete everything from the USB thumb drive and press Enter:

  7. Type the following command to convert the drive into a GPT partition and press Enter:

  8. Type the following command to select the new partition and press Enter:

After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.

Create USB install media

Use these steps to create a bootable media to install Mac OS X:

  1. Download and install a copy of TransMac.

    Quick note: TransMac is a paid software, but it has a 15-day trial solution, that give us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)

  2. Insert the USB drive that you’ll use to fix your installation of OS X. (Remember that all the data in the USB will be erased. Make sure you take off any important documents.)

  3. Right-click the TransMac software icon and Run as administrator. (You’ll be prompted to Enter Key or Run, because we’ll be using it once, click the Run option.)

  4. On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive that you’re intending to use to reinstall Apple’s OS X and select the Restore with Disk Image option.

  5. In the warning dialog box, click the Yes button.

  6. Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system. Mindnode 7 torrent download.

    Now, you’ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.

Once your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option key, and select the USB you just created to reinstall Mac OS X.

Boot

If you’re having issues trying to create a bootable media, you can get a USB flash drive that comes with Mac OSX ready to install.
