How to install on laptop with no CD Drive

[fernbuck]

Have a Acer Aspire One Mini Laptop, it has 2 Micro SD Slots and a couple of USB slots but no CD or DVD drive. It comes with Windows XP pre installed, but I want to set up a dual-boot system with Ubuntu on it also. How do I do this with no CD Drive? I don't want to go out and buy an external CD Drive just to do this. Please help.

You can boot and install from USB.

From Windows you can download the Ubuntu iso and Unetbootin.
Unetbootin will install the iso to a bootable flashdrive.
You can use this flash drive to install Ubuntu just like the CD.
Before booting, select the flash drive as first HDD in BIOS.
