The fix could be that you are using the wrong startup disk. When you turn your PC or mac on press f1 repeatedly until you come to the startup menu. From this select 'startup' preferences, start up disk and select the right one. If you are unsure there is no harm in trying them all as i doubt you will have more than 2 hard disks.
Apple supports up to Mac OS X 10.5 on the later models, and 10.4 on the older ones. They are also supported by Mac OS 9.2 and Mac OS X 10.1-10.3
Mac OS 9 is the old version of Mac OS. Mac OS X was completely rebuilt from the ground up. Except some of the programs. The interface and look is different, but things like Disk Utility and stuff are the same. Terminal is a program that never gets improvements so that's the same too.
If you have a Mac, it should already come up. If you don't, I have no clue!
Mac OS X 10.4 (Tiger) can be updated to Mac OS X 10.4.11 for free. Purchased upgrades then are Mac OS X 10.5 (Leopard) or Mac OS X 10.6 (Snow Leopard). Snow Leopard only works on Macs with an Intel processor. Older Macs with a G4 or G5 processor can only go up to Leopard.
You misunderstand the purpose of Boot Camp. The purpose of Boot Camp is to allow you to set up a dual-boot of Mac OS X and Windows on your Mac. It does not allow you to run Windows programs directly on Mac OS X.
Yes, in Mac OS 10.4 and up.
FreeBSD: v3.3.0 Linux OpenBSD NetBSD Solaris: v3.3.0 Mac OS X v10.2: up to v1.1.2 Mac OS X v10.3: up to v2.1 Mac OS X v10.4-v10.5 (PowerPC): up to v3.4.0 Mac OS X v10.4-v10.7 (Intel): v3.4.0 Windows 95: up to v1.1.5 Windows NT 4.0 Service Pack 6 - up to v2.0.1 Windows 98 - Windows ME: up to v2.4.3 Windows 2000 - Windows 7: v3.3 (Tablet PC input is not supported) OS/2 and eComStation: up to v3.2.0 IRIX (mips4): up to v1.0.3
Holding down the Option key (alt) while the Mac is starting up will offer you the choice of how you want to boot the Mac. Selecting Mac OS X will make that the default boot.
You cannot destroy Mac OS X. Though you may be angry at it, you will only end up destroying the hardware that contains it - the Mac OS X will still be there somewhere in the bits and pieces of the hardware that contained it.
The iMac G4 is able to run any version of Mac OS X up to and including, version 10.5 (Leopard).
If it is a G4 iBook produced after 2002 it may not be able to run Mac OS 9 separately. Mac OS X 10.4 (Tiger) uses the Classic Environment which runs Mac OS 9 within Mac OS X. There will be a Classic option in the System Preferences where you can verify that the Mac OS 9 System Folder is available. Double clicking a Mac OS 9 application should launch the Classic Environment. If this does not happen then: If you have a boxed retail version you can reinstall Mac OS 9 by inserting the Mac OS 9 disc, restating the computer and holding down the C key while it starts up. This will boot the computer from the Mac OS 9 CD rather than the hard disc. Open the Installer, Click the Options button and then tick the Clean Install option. Install Mac OS 9. Or: If you have Mac OS 9 on a Restore disc that came with the computer Open Software Restore and select Restore Mac OS 9 Only. If the computer originally had an earlier version of Mac OS X and is now no longer compatible with the original Restore disc you can download an updated version from the Apple support site (See links below) by clicking the Accept And Download link at the bottom of the page.
Mac OS X Lion is better than Windows 7 because it is faster, doesn't get viruses, is a lot more secure and in my opinion has a better user interface. It's up to you though to decide which is better. Remember if you get a Mac you can run both Windows 7 and Mac OS.
