There is a very fast and easy way for installing a new OS on your eeepc, without using an USB-CDROM.
It’s name is UNetbootin (http://unetbootin.sourceforge.net/) and it helps you to make an USB bootable pendrive for installing any operating system you want, having (or not) the corresponding ISO cdrom bootable image.
Download your ISO image, insert your preformatted FAT32 pendrive, open UNetbootin, select DiskImage ISO in the dropdown, select your ISO file, select your pendrive device, click OK.
At the end of the procedure, you have a bootable install usb pendrive (look inside your BIOS option for altering the device boot order of the eeepc)
