I've just bought an Acer laptop, Acer Aspire E1-571.
I created the recovery USB flash drive using the ACER eRecovery software from within Windows 8. It says it is successful and copies over 12GB to the flash drive.
I thought I would test it, to ensure it does actually work. So, I have change the boot order in the BIOS prioritise the flash drive and when restarted with the flash drive plugged in, it boots in to a blue screen where I have to choose a language. I then click on Use a Device (which it sucessfully identifies on the next page). I select the device and at this point the computer restarts and I'm taken back to the point where I choose a language. I presume it is not working as it should go to the next stages warning me to of complete loss of data etc.
I have tried full-formatting the flash drive as FAT32.
There are no BIOS updates available, nor are there any updates to the erecovery software.
