NeoSmart Technologies iReboot 2.0.1
iReboot is lightweight and easy-to-use systray tool for choosing which OS you reboot into significantly cutting down on wait time.
The idea here is to cut out the need to hit restart and then wait for the system to go through the whole shutdown process, then wait for BIOS posting then ultimately selecting the system you wish to boot into all the while in a race to beat the bootloader countdown.
iReboot negates that whole timely process by enabling you to simply right-click the systray icon and select the OS you wish to boot up - it is that simple.
Limitations:
Free for non-commercial use.
