How do you change the operating system boot order?

I am running vista and windows 7 and would like to change the boot order.



I'm also looking at installing solaris.



Would I install this in the same way I did for windows 7 with a new partition. Is there a limit on how many operating systems can be installed?



I will also probably need to change operating boot order to accommodate solaris soon as well.How do you change the operating system boot order?
On Windows 7...



Go to Control Panel Home (Start -%26gt; Control Panel) -%26gt; System and Maintenance -%26gt; System.



On the left side pane, under the Tasks, Click Advanced System Settings.



Click Settings under Startup and Recovery.



Under System startup, you can change the Default operating system between Windows 7 and Vista. If you have installed any other OS, you can change between those settings as well.
