Downgrade Compaq Presario CQ61-120EI from Vista to XP

[chunwah74]

hi daniel,

thanks for the reply.

yes, i have reordered the boot sequence, but the disc is not booting.

when the laptop powers up, i get the message "press any key to boot from CD"...

upon pressing the space bar, it will go into a red coloured Compaq splash screen momentarily before going back to the "press any key to boot from CD" message again.... and so on and so forth.

i created my boot disc using Windows XP Home Edition incl service pack 2 with nLite.

is there anyway i can double check this disc to make sure that i have created it properly?

many thanks for your help.

Use other original "vergin" Windows XP CD/DVD and go through slipstreaming process again.

This XP copy which You are using now may be corrupted.

Hello, I have a Presario CQ 61 - 340EV with windows 7. I want to downgrade it to windows XP SP3.

I am not sure if the Bios Update will work on Windows 7 since all the compatible windows versions mentioned at the download page are windows Vista versions.

Compatibility:   Microsoft Windows Vista, Microsoft Windows Vista Business (64-bit), Microsoft Windows Vista Home Basic (32-bit), Microsoft Windows Vista Home Premium (32-bit), Microsoft Windows Vista Business (32-bit), Microsoft Windows Vista Ultimate (64-bit), Microsoft Windows Vista Ultimate (32-bit), Microsoft Windows Vista (64-bit), Microsoft Windows Vista Home Basic (64-bit), Microsoft Windows Vista Home Premium (64-bit)

Please help.

Best Regards

Hi,

You've got CQ61-340EV right? So this model have Bios updates which are made for Windows 7 and Vista system.

You may find them all here in Bios category.

How to update Bios?

First check which Bios version you've got now. This information may be very helpful if ther will be any problem.

Connect the notebook to the AC power supply.

Disconnect from the internet. Exit from all programs that you are running. Disable anti-virus and firewall.

Execute the Bios update exe file. It may take some time. Allow the notebook to restart after applying the updated BIOS.

While this update is running do not:

• switch off your laptop, 

• disconnect AC power supply,

• try to run any software or do anything on it .

Bios update is always very risky and may corrupt your notebook. So be careful and have full patience. You will perform this update at your own risk.
