Ok I have a Compaq presario 5400 desktop, I want to know if it can boot from a USB drive. The desktop has 4 USB ports, How do I know if it can boot from a USB drive? Thanks in advance!

Plug it in then reboot, then go into the BIOS. See if it appears.

Under the bootdisk option.

Depending on what the brand/model of this USB flash drive is.

It may or may not be bootable. Even if your system supports booting from USB flash drives. Not all USB flash drives are bootable.

To test it, download a bootdisk from here (http://www.bootdisk.com)

Get the 98 bootdisk

Format the USB flash drive, then unzip the 98 bootdisk file, then copy the files it creates to the USB flash drive. (dont put any of the files in a folder, they have to be in the main directory of the USB flash drive).

Reboot, change the bootdisk to the USB flash drive.

See if it boots into DOS

Do you know if a 1gb sandisk cruzer micro can do this? Or maybe a 4gb PNY Attache?

What I am trying to do is make a bootable USB drive with Ubuntu on it, I have the Ubuntu Live CD but it lacks Java and for what I need this is only cuz it has to contain java in it. I tried looking for Live Cds with java installed but I dont seem to find one.

If the sandisk is the same as the one I have here (Its got cruzer micro 1.0 GB written on it)

(If its says SDCZ6-1024) on the bottom of it (the end where you plug it in).

It is bootable (well should be bootable).

I formatted this and copied the 98 bootdisk from the site I posted to it.

But if your BIOS doesnt give you the option to boot from USB flash drives / or USB devices, it wont work on yours.

However, many (all?) Live CD Linux disks have a boot manager available, which allows you to select from another device, including a USB, rather than continuing the boot from the CD. So you aren't limited to what the computer provides (I think Debian even provided a floppy image which gave that option on their installation CDs).

The current issue of APC magazine has an article on producing bootable USBs.

Article (http://www.ngine.de/index.jsp?pageid=4176)about making a usb drive bootable. Requires the XP disc, then extracting and editing some files then slipping them back in to create a modified XP ISO disc to allow a usb boot up...

Also tom's hardware has a good guide (http://www.tomshardware.com/2005/09/09/windows_in_your_pocket/) to setting up USB boot up...
