Dual boot Win7/XP fails

December 12, 2010 at 12:17:45
Specs: Windows 7
I just got a new machine with Windows 7 64 bit. I have a 2nd HDD (1TB) installed and I attempted to install XP on it.
The installation proceeded fine until the Reboot step. Instead of opening the XP install sequence I got a message telling me that
"a Disk Error Occurred. Press Ctrl-alt-del To Restart"
I tried twice, even formatting (quick)the disk but no joy. Since the XP installation reset the boot loader, I had to use the Win 7 disk to reset it back.
I have previously installed a second disk dual boot XP on Vista systems so I don't think that it is related to Win 7

The easiest way, to get it to work is, to first install windows xp and then windows 7.
In that case, the windows 7 boot loader recognizes the windows xp and adds an entry in the boot menu for the windows xp.

The system came loaded with Win 7. The XP install process has problems. I know how to redo the boot loader once XP insstalls but I cannot get it installed.

Have you checked the controller settings in your BIOS.
You have to switch it from AHCI to IDE, to get windows xp installed.

Thanks. I have solved the problem, but I am not sure why it worked. I disconnected the Win 7 boot drive and then the XP Pro installation went just fine on the remaining drive. Then I reconnected the Win 7 drive and had a dual boot system.
Why it wouldn't install with the Win 7 drive connected is a mystery to me.

As I mentioned above.
To install several different windows versions, always start with the oldest one and end up with the newest.
This normally works fine.

Problem is solved even though I might have done it the hard way.
