Downgrading Win8 to Win7 on an acer laptop

[Ignocia]

A family member of mine recently bought this Acer laptop recommended by me, i personaly prefer Win7 far over Win8 so i suggested that family member to buy Win7 home premium together with the PC as we couldn't choose to change the OS as we bought it.

Now we've got the new pc and the win7 disc. When i try to install win7 on the laptop it gives me an error:

"windows setup experienced an unexpected error. to install windows restart the installation"

I've tried to google the issue with no luck, so i am hoping to get some help on this forum.

Cheers Ignocia.

1) Downgrade to Windows 7.
Downgrade Windows 8 to Windows 7
Warning you must have the uEFI/BIOS firmware setting in Step Three set.


2) If Using a USB Pendrive on a PC with a uEFI BIOS.
USB Pendrive need to be formated to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

Enabling the boot device menu

On most Acer systems, you can use the F12 key on boot to select the drive or network from which loading the operating system. In case the F12 option does not work, you may need to enable this function.

SOLUTION

Enabling the F12 function:

1.Power on the system. As soon as the first logo screen appears, immediately press the F2 key, or the DEL key if you have a desktop, to enter the BIOS.
2.Press the right arrow key to select Main.
3.Use the arrow keys to navigate to F12 Boot Menu, and press ENTER.
4.Select Enabled, and press ENTER.
5.Press the F10 key to save changes and restart the system.

How to Enable or Disable Secure Boot

This article only applies to: Windows 8 Desktops

Bootable media from previous versions of Windows may not be recognized in Windows 8. You can change the Secure Boot setting and it should recognize the bootable device.

Use the following steps to change Secure Boot:

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 BIOS.
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.
7.Press Enter.
8.Press the F10 key to save changes and restart the system

2nd: when i open the boot menu theres only 1 option: "windows boot manager"

Windows Boot Manager will always be the first boot device in BIOS settings for Windows 7/8 installed in UEFI mode.

You must have CSM ENABLED.

All I could find on the ACER web site.

Downgrade Windows 8 to Windows 7 - Page 14

I have a notebook Acer Aspire V3-571 with Win 8 preinstalled.


If you want to use Windows 7 on your system, you have to leave the CSM enabled.

In the BIOS setup I have "Boot Mode" with two options: "UEFI" and "Legacy BIOS".

look at all the page in the BIOS.

 

[Ignocia]

Yes. Its set to UEFI

Once booted into BIOS setup, did you check on the Boot tab? Then check Security.

If you will take camera snaps of the tabs we can guide you better: Screenshots and Files - Upload and Post in Seven Forums - Windows 7 Forums
