Today I was trying to install Windows 7 x64 on new computer. Setup immediately stopped with the following screen:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disk and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disk, contact your system administrator or computer manufacturer for assistance.
Info: Windows failed to load because the firmware (BIOS) is not ACPI compatible.
I did a google search, and most posts were referring to ‘BIOS setting for APIC (Advanced Programmable Interrupt Controller) not being enabled’. However it does not helped much.
Solved this by enabling ACPI BIOS setting.
