Mr_Mischif Posted November 16, 2006 Share Posted November 16, 2006 I've got a mobo that can boot from USB, now I need to know what medium it needs. Can I have a ISO in the root folder and it'll boot fine or what? Quote Link to comment Share on other sites More sharing options...
Uncle Toxie Posted November 16, 2006 Share Posted November 16, 2006 I want to say that just having an iso on the drive is not going to work. What you need is to have the OS "installed" on the flash drive, like you would on any hard drive. The only difference being is that the flash drive is removable. If I am wrong about the iso bit, someone feel free to jump in here and call me on it. Would be interesting if you could do that though.........

cooper Posted November 16, 2006 Share Posted November 16, 2006 Think of your USB drive as a floppy or a CD. You don't put an ISO on any of those as a regular file to get the thing to boot off of it. No, you dump the ISO onto the medium, starting at the first sector and move on down the device, completely oblivious to things like filesystems. Once done you take it out/off, place it back in/on and hey! Lookit that. A filesystem is there complete with content. Quote Link to comment Share on other sites More sharing options...

So would this mean that the USB drive would have to be devoted fully to the ISO, or could I partition it? I use it for things like school work also, so I need like 30-50MB left for myself.

cooper Posted November 16, 2006 Share Posted November 16, 2006 Yeah, you can partition it. It's after all a harddisk or sorts. Not sure if an ISO also contains the partition table of the drive though. Probably does. More interestingly, once that data is on there, ISO or not, it's still basically a writeable medium. As long as the filesystem allows it you can add files (iso suggest ISO/UDF filesystem, which don't typically allow this). Quote Link to comment Share on other sites More sharing options...
remkow Posted November 16, 2006 Share Posted November 16, 2006 If you just want to install an OS on your USB stick, google around. There are a lot of tutorials explaining how to do it, both for windows and linux one for windows on usb here: http://www.tomshardware.com/2005/09/09/win...in_your_pocket/ Quote Link to comment Share on other sites More sharing options...
Mr_Mischif Posted November 16, 2006 Author Share Posted November 16, 2006 Well do you know any ISO burning programs that will allow me to burn to my drive? I've always used Iso Recorder for my ISO burns, but it only writes to CDs[/url] Quote Link to comment Share on other sites More sharing options...

Mr_Mischif Posted November 20, 2006 Author Share Posted November 20, 2006 OK, now I've dl'd the file and installed it on my flash drive, but now it throws a kernel panic, and I can't load my preferred ISO. It throws VFS: Cannot open root device "<NULL>" or unknown-block(104,2) Please append a correct "root=" boot option Kernel Panic: VFS: Unable to mount root fs on unknown-block(104,2) And I have phlak at /components/phlak-0.3.iso but I can't seem to boot to it.

cooper Posted November 20, 2006 Share Posted November 20, 2006 Sounds like the kernel you're trying to boot doesn't have USB support. Quote Link to comment Share on other sites More sharing options...

cooper Posted November 20, 2006 Share Posted November 20, 2006 Your point being? The kernel doesn't know what a USB device is it seems. Maybe it was designed to be started from a CDROM. Quote Link to comment Share on other sites More sharing options...
