Q: uninstall bootcamp from windows 7

I have Windows 7 installed on my MacBook Pro '07 with no Mac OSx installed. I want to uninstall Windows 7 and install Mavericks. Everything I've seen says to boot up in the Mac OS to uninstall, but I can't. Is there a tutorial out there I can follow - or could someone layout the steps. I have Mavericks on a flash drive ready to install.

 

Thank you.

    You can install OS X (compatible with W7) on an external disk - OS X: Installing OS X on an external volume - Apple Support .

     

    If you already have the Mavericks Installer.app on a USB, you should be able to plug it in, and power cycle your Mac and hold the Alt Key. You can connect another external drive and install Mavericks on it, boot from it and remove Windows.

     

    Another option is to use to boot from the Mavericks Installer, run Disk Utility, erase the internal disk completely, and install Mavericks.

     

    You should back up Windows first, before you erase it, in case you forget to retrieve something and need it later.

    What is in the .dmg file? Mavericks?

     

    Do you have the 'Grey' restore disks? Does your Optical drive function properly?

    No restore disks....just Mavericks.dmg file.

     

    If I start up Windows can I install Mavericks from there?

    1. Can you download the Free Edition of http://www.dmgextractor.com/ on the Windows side? You need a large enough USB to accommodate the expanded contents of the DMG. If you know the size of the restored DMG is larger than available disk space on an external disk, please stop and find a large enough disk. DMG Extractor will show you the expected size when expanded.

    2. Copy the Mavericks .dmg to the Windows Documents folder. It would be better if you had a spare USB which can accommodate the DMG contents.

    3. Use the tool in step 1 and erase the spare USB (if available) and extract the DMG to the USB. It should be bootable, if the source was a bootable Mavericks installation. It should also be a GUID flash disk. If it is not, please stop.

    4. Make sure Windows Disk Management shows the restored USB to be a GUID disk.

    5. Test booting from this USB. If it does not boot, stop.

    6. If it boots into Mavericks, power-cycle and test that you can boot by using the Alt Key.

    7. At this point, boot from the USB, run Disk Utility, and erase you internal disk. If a spare USB was used, expand the DMG to the internal disk which should now be bootable in Mavericks.


    Let us get to this stage. after you expand the USB, check in Windows Disk management if you see a 620MB partition on the USB stick. If there is one, it is most likely the Recovery HD. When booting from the USB, try holding Command+R to see if you can see a local Recovery Console. This may simplify some steps.

    So it looks like I'm going to have to purchase the Home Edition because the .dmg file is over 4gb. However, I just booted up the MacBook and the trackpad and trackpad buttons aren't working. So I'm going to try and figure this problem out and then come back to this one.

     

    Thank you for your help!
