As the companies build smaller and less expensive laptops (aka netbooks) it becomes more difficult to repair them.
There are a few options that depend on what is built in to the netbook.
To repair it properly you need access to the recovery console.
A few possibilities.
According to what I found you need to get to the bios for the boot order. It needs to be set to "boot from USB"
It should be F2 or F12.
If you created the recovery console correctly on the USB and
you are booting from the USB you should get the recovery console.
Since there is no CD drive, you can't install Ubuntu or use Puppy linux that runs from a CD.
You might be able to install Puppy to a USB, but you need to boot from the USB. You can build a bootable USB, but it not as easy as burning an iso file to a CD.
If you can do this, then you might be able to move the file over. There are no guarantees this will work because there might be other OS files that are corrupt.
The following info tells how to use and run the Acer One Recovery (this restores the unit to factory defaults. You will lose all data and programs)
It uses the recovery CD's that should have come with the unit.
You can use a USB CD drive or build a USB bootable flash drive using the recovery CD's. The Acer One Recovery
link shows how.
If you have data to save, you will have to either remove the drive and slave it to another computer or find a way to boot from USB flash with a linux OS or a USB portable CD drive with linux.Acer One - Find AnswersAcer One Recovery
From what I have researched the only easy options are RC.iso on a CD using a external cd drive or the recovery option from Acer.
For the RC.iso go to the link at The computerparamedic.com that is in this FORUM
