I was thinking, when I put in my Ubuntu cd, and boot off it, and go into the "Something else" section in the install window, my flash-drive is there when plugged in. I noticed it had one partition. I thought hey, what if I, in that window set the "Device for boot loader installation" to my flash drive ("/dev/sdf"), delete the partition on the flash-drive and make a root ("/") and a home partition and install...
I mean will it work? Well, will what work is probably your question. I mean if I tell it to boot off of the flash-drive, will it act like any normal hard-drive?
I should note here that the flash-drive I had in mind of using is 16GB, so no worry about space.
The reason I haven't tried this is because this requires deleting the partition on the flash-drive, and I'm not sure if it will be usable later when I make a basic data partition on it. And I'm not sure if it will mess something up.
Just a thought
P.s. I know I can use a Linux-live CD or USB, I'm just wondering if this works.
