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:
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?
1.Completely shut down your computer.
2.Power on the system. As soon as the first logo screen appears, immediately press Delete to enter the
3.Use the right arrow key to select Authentication.
4.With Secure Boot highlighted, press Enter and then the down arrow to select Disabled.
5.Use the right arrow key to select Boot Options.
6.With Launch CSM highlighted, press Enter and use the down arrow to select Always.
8.Press the F10 key to save changes and restart the system
Or you need to switch off UEFI. If nothin doesnt help trye downgrade BIOS(link below)
I joined just to say Thank You Tom, I was having this problem and fortunately Google found your post.
I too signed up to give Kudos, I have an ASUS laptop with the same problem, this was just my second day of researching, glad to have found this post, Thanks!
Registered to say thanks to Tom as well. I just got my Aspire S7 and wanted to put Win 7 on it, but it kept freezing. The fix for me was to turn off UEFI. I appreciate it!
