I have Windows 7 Home Premium on my machine and want to install Windows XP as well.
When I run through the Windows XP installation, it copies all the required files and restarts - I then get an NTLDR is missing error and can't do anything.
I'm able to repair the system using the Windows 7 repair CD and it works again, but I can't install Windows XP.
I think the problem is that my hard drive is in SATA mode in the BIOS settings and Windows XP should install on IDE mode. Is this correct? If so, how can I change from SATA mode to IDE mode?
+1. The BIOS change is the quickest and dirtiest way to handle this in my experience. – None – 2011-09-07T22:28:47.533
Wait, would Windows 7 still successfully boot after that, without changing back to SATA mode? I never tried this, instead always find the SATA driver for XP because I thought 7 won't boot afterwards – Martheen Cahya Paulo – 2011-09-08T00:40:21.263
1@Martheen Cahya Paulo - Honestly, I missed the "too" part, thought it was a change to Windows XP. Honestly, you are correct if it was installed that way - reinstalling under SATA would work, or changing the option back each time. You are right however, finding the correct driver for XP is by far the best way as this can lead to increased performance. – William Hilsum – 2011-09-08T01:52:52.380
