My test machine has 3 system partitions, 2 XP and 1 Win2003. Often while testing I will have to reboot, and sometimes I'll want to switch to a different machine while it does that (or I'll space off). What I've always wanted is to have a program that would run at startup and simply set the partition that has booted as the default and then exit. That way when I install something and have to reboot, I don't have to worry about selecting the right partition, it'll automatically go back to the last partition I was in.
In addition it would also be nice to be able to run the program manually to select the partition I want, along with some other options for booting into the different safe modes, VGA mode, load last known good config, and the others that show in the boot menu when you press F8 while booting.
Ideally it would be great if it could auto-install into all partitions. I would imagine that if this didn't need to create registry entries and such to install it could just be copied to the desktop, with shortcut in startup directory, for "all users" in each partition found.
I hope someone will take this one up.. it seems like it would be easy to do, and would be immensely useful to me
