Lets just say a computer had 3 internal harddrives:
c: 500 gigabyte ntfs drive for windows 7 (boots automatically when computer is turned on)
d: 2 terabyte ntfs drive for general stuff like backup, games, movies, music ect...
g: 1 terabyte drive unformated ready for use.
Lets just say I wanted to install ubuntu on the G drive so I have a full nice and fast Ubuntu installation without any problems of partitioning my main windows 7 drive which could corrupt files. Now I want my computer to boot normallly when I use it day to day and I don't want grub to pop up all the time and currupt the windows 7 boot loader. So can I install the boot loader on the usb so it only boots an alternative os (e.g. ubuntu) instead of windows when the usb is plugged in on boot?
Could I install 5 different distros such as arch, ubuntu, fedora, debian and slackware as well as DOS 6.22 and windows 3.11 and windows 95 and 98 and xp on the G drive with about 9 100 gig partitions each storing an os and setup a boot loader on a usb to only boot those os's if the usb is plugged in? Would this many multiboots be possible with the grub boot loader? Would installing any of these operating systems mess up the windows 7 boot loader on the c drive?
Let's just say I love having fun with a variety of software and operating systems but I don't like having them as virtual machines
