Yesterday, I fixed a friend's computer whose windows system got completely messed up because of a botched stick of ram.
He was using a netbook without a cd-rom drive, so his installation cd was not useful. However, the installation CD contained all the information I needed to restore the computer.
So, I created a bootable WinPE system on my USB flash drive, and modified one of the boot files to boot directly to norton ghost (a hard drive re-imaging program). However, I still could not get the factory hard drive image file onto his computer since that was still on a cd. The image was 2.1GB. My flash drive was 1GB, and my SD card was 2GB, so those won't work. What do I do now? Not to panic, I deleted a bunch of music off my IPOD, and copied the image there using my laptop cd drive. Then, back on my friend's computer I booted off the modified WinPE from my flash drive and went into Norton Ghost. Norton recognized my iPOD as a hard drive with data on it, so I was able to re-image the hard disk by pulling the ghost image file real-time from my iPOD and on to the netbook's hard drive. The whole thing worked like music. It was beautiful.
I rule.
