I have an Acer Aspire One netbook with Windows 7 Starter.  When I switch it on it goes immediately to Startup Repair, says that repairs were not successful and the computer cannot be repaired, restarts and then does the same thing again and again.  I was advised to reinstall Windows using the option to retain user data.  When I do this, the progress bar remains at 0% for some time and then this message comes up:
"Restore failed - error code=0x45d (WIMApplyImage cannot apply image : The request could not be performed because of an I/O device error.)  Restore unsuccessful.  Please try Restore Operating System to Factory Defaults."
Is there any way I can backup the files on my computer before I do this?

I/O error usually indicates a hard drive problem.


Download Puppy linux on another computer. Create a bootable USB flash drive with Rufus. Run Rufus and select MBR for a partition scheme. Leave everything as checked including Quick Format. Where FreeDos is shown in the dropdown box select iso image, click the folder icon, and browse to the iso image of Puppy you downloaded. Press Start. Backup any data on the flash drive as it will be erased.


Attach the USB flash drive and boot. Your hard drive partitions are in the lower left of the desktop labeled sda1..sda2...sda3 depending on how many you have. Your Windows partition should be labeled sda2. Click once on the sda2 icon. This will mount the partition and a File Manager will open. If you do not see your Windows files close out the File Manager and select another sdaX partition. Post back if you see your Windows files and I will post instructions on how to copy to another flash drive.


I recommend Lucid Puppy for compatibility. lupu-528.005.iso

You may need to have USB boot priority in BIOS. Tap F2 at boot and make sure USB is at the top of the boot list.


Some Acers have a setting in BIOS called D2D. This must be enabled before doing a factory reset.

 As JohnC_21 says, you can boot up Linux and save your files.  I use Linux Mint myself, but there are many versions available.  Note that you can boot Linux and run it without needing to install anything on your hard disk. 


  When you've gotten your system back like you want it, I urge you to get yourself an external hard drive and a good 3rd party backup program. You can set it up to do everything automagically at the time and frequency of your choice. 1 TB external hard drives are about $50 these days and a really good FREE backup program is the Easeus Todo Backup Free.  That can save you a lot of time and frustration the next time something like this happens. Sooner or later it happens to all computers for one reason or another.

 Good luck.

Make regular full system backups or you'll be sorry sooner or later.
