Q: Cannot boot to mac os after installing windows 7 via boot camp
-
Aug 5, 2014 5:56 AMby Lancermast,Thanks Carolyn. I am in now.
By the way, shall there be a Boot Camp Control Panel in Windows to control which OS I want to boot?
Is there anything I can do to rectify the faulty multimedia drivers and most importantly the wifi driver in Windows 7? Wifi hardware is detected at all in Windows 7. It doesn't appear in Device Manager in Windows.
Thanks again.

Aug 5, 2014 6:53 AMby Lancermast,I followed the steps of Boot Camp Assistant, I remember there is a step that automatically download necessary drivers, etc during the process. Is this what you are referring?
Is there any way I can install drivers in Win 7 Home Premium 64bit when I booted into Windows? Perhaps you can point me to Apple drivers download site for Windows.
By the way, I didn't see the option of Windows EFI install or CSM-BIOS install options during the Windows installation process. Could you elaborate further? Or point me to an URL. I am very new as this MacBook Air is my first Mac computer. I am sorry if all these sound very elementary.
Thanks.

2. Normally, if you let Bootcamp partition your disk, and let it do a normal install, it is a legacy BIOS based install. There are limitations imposed because of this method, which for example disallows this disk from being partitioned any further. In contrast, an EFI installation must be chosen during the reboot when the Bootcamp installer switches from OSX to Windows using the ALT/Option Key and selecting EFI boot. This has it's own set of issues.
If you did a 'normal' installation, it should be BIOS-based. For example, if your sound works in Windows, then you have a BIOS installation. It does not work on older MACs properly with an EFI install.

Aug 6, 2014 12:17 AMby Lancermast,I didn't do any changes, just let Boot Camp Assistant do the necessary after creating the USB disk, I guess I've done a BIOS based normal install although I didn't hear any sound from Windows.
I'll try to install all the necessary drivers from Windows.
You mentioned BIOS based install cannot re-adjust the disk partition later, does EFI installation make resizing partition possible?
What's the limitation/issues with BIOS and EFI based installation in general?
I'm using MacBook Air 2014 edition and have done all the available updates.
Thank you very much.

BIOS limitations are
1. Windows partition re-sizing is not allowed and is not supported by Apple - Boot Camp 5.1: Frequently asked questions
2. Limits your ability to changing the size of partitions on single-disk systems.
3. Apple software (like Disk Utility) can cause problems during upgrades.
4. Slower to boot.
5. Multi-boot OSEs will not work. This is typically a case for developers who work on multiple OSes.
EFI limitations are
1. Not all hardware is fully supported or exposed. GPUs and Sound are primary challenges. This is also sometimes a consequence of vendor-specific firmware on hardware. For example lack of WiDi support on Apple devices where AirPlay is preferred.
2. Vendor support is slowly gaining ground, but is not universal. Some HW may not work at all.
You can read technical material on Microsoft or other websites for further details. Macrumours has some excellent discussion threads.

Aug 15, 2014 1:05 PMby Thokim84,I am having a similar problem because in windows 7 my USB 3.0 doesn't register my flash drive being plugged in and thus have no access to the bootcamp drivers. The USB ports show a problem in Windows device manager as they have no driver so I am stuck. How do I get access to the drivers on the USB without the driver for the USB?
