Well, first you need the OS on a hard drive (Probably the external kind) You can do this with a HDD Copier. Then you need to set the computer (school's computer) to boot from the Ext. HDD. This can be done in the BIOS. Plug it in and it should work! (Make sure you have the Intel version of the Mac OS)
Notes:
1. The above instructions will not work
2. Mac OS X can only legally be installed on Apple computers.
3. A school's network should not allow a user to perform this kind of operation.
Microsoft does not offer free copies of Windows7. If you already have Windows XP or Vista, you can buy the cheaper upgrade version (119.99 USD) instead of the full (199.99 USD) version. However, your school or employer may subsidize Windows, making it cheaper, or free.
Because you did not format it properly, or you have deleted partitions, and all free space is in unallocated sector.
Add more RAM. That is the best way. Adding another harddrive would have little effect. Make sure to have plenty of free disk space on your harddrive so Windows can use virtual memory.
Virtual memory is determined by 2 factors. First, the amount of free hard drive space available on your hard drive. Secondly, it is determined by your virtual memory settings under Windows properties. Assuming you have not changed your Windows default settings, then every ounce of free harddrive space IS virtual memory.
Use VLC Media Player instead of Windows Media Player and you have that issue solved.
You can't; use Windows Movie Maker instead; it is a free download from Microsoft.
No, Windows 7 is not free.
Apparently, Windows 8 can be 'rolled back' to Windows 7. HOWEVER - some manufacturers say your warranty is void if you do it - and will not do a (free) repair if your computer goes faulty within the guarantee period !
There are no legal ways of downloading Windows XP for free. People may choose to go the illegal way and pirate it instead of paying for it, simply, because they can't afford it.
No, there is no free speech to text software for Windows 7. Microsoft Office includes this capability, and there are many commercial programs that do this.
Yes, Windows 10 will be free to people with windows 8.1
instead of windows you can have linux or mac. they are different, but you will know whats best for you when you try them, linux is free to download.but you need an operating system (windows, mac, linux or any other OS) for the computer to work
