Linux on USB flash/HDD, bootable as well as virtual
Hello Guys, I was searching for a some operating system which can be installed on the USB flash drive as well as external HDD. The best option available is Linux and its variants. I got fedora 14 installed on USB flash drive it ended up as virtual system, on a Virtual box, further it is too slow to boot, even with 2GB of RAM. Then I came across the Slax or slackware, it is bootable, fast but cannot run as virtual system. I am looking for some OS which should be fast, which can run both in Virtual environment as well as live i.e. bootable, further I should be able to install softwares like open office. I know I am demanding too much but it is linux, and as I know anything is possible in Linux. . . Thank you . . .
