Problems After Downgrading To Windows 7 In Aspire M5-581TG

DeathWish

Hello

 

I have an Aspire M5-581TG. It came with Windows 8. Three times when I've started it up it says it's someting wrong with the windows installation. Same thing happened all three times, throwing the repair screen in my face and after several of hours (even days) it installes Windows 8 again.

 

Well, after 9 hours of repairing screen the third time I decided to upgrade my Windows 8 installation to Windows 7. Followed some tips from this forum and I got started with the installation (Windows 7 Professional 64Bit SP1).

 

Here's where the problems start. It is all so slow. Installation takes a good 10 hours. Just booting Windows is an hour. I've read about others that have gotten this problem but never seen any solution. It does not get any better when I install the drivers (installing drivers take hours as well). Anyone know anything about this problem?

 

Any help is appreciated. Thanks.

I have that same model with SSD. I've not read anything about this problem.
In my case, once I had worked out the necessary steps (nothing had been published when I upgraded mine), everything went fine. It boots in the blink of an eye and runs absolutely fine. Assuming you followed all the steps, I wonder if your laptop has a problem that was also the cause of your Win8 issues.

 

As a check, you should have followed these steps:

 

Disable secure boot.
Remove ALL passwords (or risk a frozen drive).
Switch from UEFI to legacy.
Ensure SATA Mode is AHCI.
Do NOT replace BIOS (leave the Win8 one supplied - it is absolutely fine and provides future upgradeability if needed).
Install Win7 (have Win7 completely wipe and partition drive). Be sure you are happy doing this - recovery option will be gone).
Load all driver for Win7 from Acer download site (with the exception of nVidia - get 331.82 direct from nVidia).
