My dad installed Windows 10 on my mac using boot camp as I understood. When I try to log in to Macos or see if it is there it seems to be gone when I turn the computer on, there is only option to choose Windows, when I select option of restarting the in Macos it says that it 'Could not allocate the OS X boot volume'. This happened before, and my dad was able to fix, but his brain tumor progressed so far that he is as functional as a 3 year old, and has no idea what I am talking about or what to do with computer. I know nothing about computers, which sucks, I do not even need the Macos system, but I really need that memory, or at least most of the memory that was dedicated to Macos. It looks like a common problem, but I can't seem to follow the instructions people posted. I hope someone here can help, I have no money to pay tech services
Reinstall from macOS Recovery
macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu in the menu bar. This menu is also available in macOS Recovery.
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following combinations on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.
Command (⌘)-R
Reinstall the latest macOS that was installed on your Mac (recommended).
Option-⌘-R
Upgrade to the latest macOS that is compatible with your Mac.
Shift-Option-⌘-R
Reinstall the macOS that came with your Mac, or the closest version still available.
You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.
When you see the utilities window, you have started up from macOS Recovery.
2. Decide whether to erase (format) your disk
You probably don't need to erase, unless you're selling, trading in, or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Traktor pro 2 free download windows. Learn more about when and how to erase.

The version of macOS offered by macOS Recovery might differ in certain circumstances:

- If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
- If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
