I just restored a few acers over the last month. I had the DVDs created from eRecovery so I put the first disk in and booted from that (I had the stock BIOS settings where it boots from the DVD drive.) It installed just fine.
If you have failed hardware you'll have to fix that first as that must work to install Vista.
I have to reinstall Vista or XP_ to my ACER 9520 laptop but erecovery managemnet does not work and the dvd driver also does not work. I could not find any solution anyone have an idea? I cannot open even in safe mode.
