For the last couple of days I've been trying to install Windows 7 64-bit on my new ACER Aspire X3470 that came with Windows 8 preinstalled. Looks like it only supports UEFI since I couldn’t find any other setting in BIOS utility. When I try to boot it from the Win 7 DVD it’s hanging on “Starting Windows” screen after the files are loaded and the system is rebooted. I tried to run it in “Safe mode with Command prompt” and it stops at:
Loading Windows Files:
Loaded: ...\system32\drivers\disk.sys
When I start the installation from Win 8 interface and choose disk partition that was created with Win 8 I’m getting this message:
“The partitions on the disk selected for installation are not in recommended order. For additional information about installing to GPT disks go to the Microsoft website and search for GPT. Do you want to proceed with installation?”
If I go ahead it’s hanging again on “Loaded: ...\system32\drivers\disk.sys” after the system is rebooted.
I’ve tried to delete all partitions on the disk and convert it to MBR but the result was still the same probably because it’s an UEFI system and works only with GPT disks.
I’ve also tried to create and EFI-only version of Windows setup using oscdimg.exe per this: http://www.insanelymac.com/forum/topic/184349-force-windows-7-install-dvd-to-do-an-efi-boot/
but the result was still the same.
I’ve got Windows 7 installation disk from MSDN with my subscription. Also tried Windows server 2008R2 installation (since my ultimate goal is to use it with Hyper-V) but the result was exactly the same.
Do I have any other options?
