Not many solutions here
I just worked out how to do it though, assuming you have another computer with a cd/dvd burner that you can copy files to, from the Acer.
You need to download a tool called Virtual CD. There is a free months trial - you only need it long enough to create your images. It will create a file on the c-drive that eRecovery will see as a virtual CD or DVD writer. When the file has been burnt you need to tell Virtual CD to insert the created file, in order for eRecovery to "verify" the image. You then copy the image files to your other machine and have Virtual CD write it to your CD/DVD drive.
I tried other similiar tools but could not get them to work with eRecovery.
