I'm in it to my knees. The long and short of it is I bought a new hard drive, mine is on the verge of failure. I thought I could use the Repair CD's I got from Microsoft to reinstall, then just re-register it with the OEM license. Acer tells me this isn't possible that the motherbd won't recognize it. They said it has to be done using the original OEM edition of Vista. I can't find it. I tried the next best thing, I was going to restore to factory settings and create a new copy, can't do the either because the eRecovery doesn't work. I've hit alt F10 until I'm blue in the face. I then went into computer files and checked the Acer files. eRecovery is there, it just doesn't work when I try booting to alt F10. I did find a backup of all of my Acer files that I made last year, the original is 2007. I checked it against what is on the computer. Sure enough some of the Acer files are missing. On the backup is a file called Acer Inc., inside it is another folder marked eRecovery, inside that is a application file called D2D??? Is that what opens the eRecovery environment? I contacted Acer, their response was. "You are out of warranty, for a fee we will be happy to help you although we can't guarantee results". In plain English, give us some money and go to hell. I can't even do an upgrade to windows 7 because I have to have the OEM license to back it up with. Without the OEM license the only other option I have is to spend $300 for the retail version. I sure as hell won't put Vista back in if I have to buy a new licensed copy of something. Anybody got any suggestions??
