i repair alot of computers and install windows alot. currently i have to carry about a big cd wallet with all my disks but i use a usb hard drive just now for installing windows 7 32 because its soo much faster to install. now my question is is there a way to put all my windows disks on the one hard drive and boot the iso i select? like a boot manager for iso files? that way i could have all my windows, linux and boot disks all one one drive rather than a load of dvds. my only other option was a flash drive for each operating system but thats an expensive way to do it.
