I have tried installing XP on three different drive on my Acer 7750G-9411 laptop, preloaded with Win 7. My newest drive is a 1.5 TB HGST. My other drives are a 750GB Toshiba and a 1TB western Digital. On every drive XP fails with the standard 0xoooooo7B error, warning that there may be a virus and do an FDisk/f. Of course, that's not possible unless DOS is on that machine...and it obviously ain't. CHKDSK does indicate minor issues but nothing that would cause an install failure. I virus checked my drives with the newest updated Bit Defender, no virus found.

 

I want to dual-boot adding XP on my machine in order to play old XP and DOS games.

 

On each drive I have successfully installed and re-installed Vista, Win 7 and Ubantu on all three drives. Do a full format on each drive....and XP still fails.

 

Is there some hardware conflict with a three year old machine such that that XP can't install on it?

 

Thanks

There are may reason that could cause a problem. My bet is the hard drive controller is too new for XP. You could try slip streaming SP3 into the install. That has updated drivers and should install properly.
