Hi, very frustrating problem I have with this laptop I received. It is an Acer Aspire 4720z. I have tried 3 different file sources to get an XP ISO working with this, none have been working. Every time The install is finished, I restart and it tells me it cannot find the OS (I forget the actual error, maybe it was corrupted or something like that? I have windows 7 on it at the moment and don't want to risk losing it all together). I have used ImgBurn on disks, and WinUSBMaker on USB drives, both have the same problem. ImgBurn on a Windows 7 ISO worked perfectly. What is going wrong here?
Did the machine originally come with Win7 or XP?
If it came with Win7 there may not be drivers available for XP.
In BIOS, set SATA mode to IDE/Legacy. Windows XP does not natively support AHCI.
Either change the sata mode a s mentioned above or use nlite to slipsream the ahci/sata driver onto an XP disc.
I did use IDE mode and that is the error I get unfortunately. The machine came with vista and I am attempting to fix it. 7 Is "ok" to have it be finished, but I would be much happier putting XP on this for them.
