I know it's possible to install windows xp to a flash drive, But how to do it? I have tried installing it with my windows xp usb drive installer, but weirdly it will install to a flash drive , but it won't boot, it somehow puts the mbr on a different drive , sometimes it will do it to the install usb drive, or even the main hard drive. Do I need to use the hitachi microdrive filter driver, that make windows recognize a usb removable drive as a standard fixed disk. Or is there a way to remove the standard disk driver and replace it with the hitachi microdrive filter driver for the usb flash drive, or use the hitachi microdrive filter driver. Would i have to replace the driver by making the hitachi driver as a textmode driver , so during installation it uses it as a the driver for the usb flash drive.
