How to downgrade windows on C445

Hello
I have a Lenovo All In One C445 at work and have many trouble with it.
It have Win 8 from factory so I tried it, it's crap but didn't have time to change it since someone install virus on this computer... As I don't want to spend hours erasing all of it, I tried to install Windows 7 instead of using win 8 recovery.
I disabled the BIOS OS change security (why this useless thing ?) and tried to install win 7 on the same disk as win 8 (wanted to replace win8 even if it's a dirty way) after reboot the win 7 logo move, and move and nothing appen even after 1hour...
I restarted on win 8 and reduce it's partition to create a new on for win 7. After install, same "freeze", unable to complete installation.
So as I need a computer to work I tried to use the win 8 recovery, launch it from win 8 but after reboot I have an error message "recovery partition has been destroyed" and now can't do anything, each restart end with this error, I can't boot from CD, I even can't go to the BIOS... NOTHING !
I didn't destroy the recovery partition, i just splitted the big one and create a new one, but as the letter (X by defaut) seems to not be the recovery now, it's stuck in an infinite loop...
How can I unlock this stupid computer ? Any "reset" jumper on the motherboard ? Or some magic keyboard key ? (I tried classic F2, F8, F12, del, escape...)
Why do you offer win 7 drivers if you don't let use install it ?
I'm so boring about OEM computer, we buy stuff we can't use our own way...
Thank you in advance

Actually that's where you are wrong, according to Microshaft's website, Windows 8.1 PRO installations have "downgrade rights" BUT ONLY to Win 7 PRO or Win Vista Business (BAHAHAHAHAHAHAHAHAHA that's a joke)
http://www.microsoft.com/oem/en/licensing/sblicensing/pages/downgrade_rights.aspx#fbid=-wiBOot8mXl
Sadly this leaves Enterprise/Business editions out of the question...This has been extremely bothersome considering BitLocker is only included in Win 7 Business and higher (Being part of a HIPPA compliant Mental Health Agency this is EXTREMELY important
to our functioning, especially now that TrueCrypt has ended their support and no longer even offers a download that will let you encrypt the system drive! Leaving us fumbling around trying to find a new solution)
Actually as I wrote this, I uncovered this amazing little PDF from Microsoft explaining with exact details
http://download.microsoft.com/download/6/8/9/68964284-864d-4a6d-aed9-f2c1f8f23e14/Downgrade_Rights.pdf
You must upgrade your Windows 8.1 Pro to Enterprise Edition (I've been told the upgrade is only 40$ (USD)) then you may Downgrade to Win 7 Enterprise...Still a little bit obnoxious just to downgrade but if you aren't working for a company with 100s of PCs
(Like me) I guess it's not so bad.

I have a few doubts regarding this..
1. Wil this erase all my data from all the drives...I had a single drive when I brought it at first, I manually partitioned it..
OK. You did not provide that information before. So my previous post was a waste of time. You will need to purchase recovery media from HP. If you had recovery media available and selected factory image recover, it would delete and recreate partitions on the boot drive not the secondary hard disk.
Looking for recovery disks or usb recovery media?
2. What about reset or refreshing the pc. Will it help?
No. Reset or refresh will only refresh to the current Windows 8.1 operating system
3. Is it going to be windows 8 single language again.
It won't work if there is no recovery partition, so you don't have to worry about that
4. How can I stop the installation of windows 8.1 in future.
Modify the Windows update settings. See the following image

Most likely because of the UEFI used in Windows 8. It is not by coincidence that this happens. Look at this to help: http://distrowatch.com/weekly.php?issue=20121126#qa

How to: Downgrade from OS 9.2.1 to OS 9.1 or Earlier

Been looking everywhere for an answer...
I have a PowerBook 2400c, won't boot into anything over OS 9.1. I have installed onto a hard drive OS 9.2.1 and now I have just learned it is not compatible with pre-G3 machines. I get an error message when trying to boot into OS 9.2.1 on the 2400c that the system is not supported, and it is overlayed the OS 9.2 Boot Window.
Since I only have a full, retail OS 9.2.1 install CD, and nothing earlier, I am looking for a way to downgrade it to OS 9.1. I tried to just install the 9.1 update overtop the 9.2.1 system, but it will only install it overtop OS 9.0-9.0.4.
By the way, and this is just for information, OS 9.2.1 is installed on a CF card. I boot my older machines with Systems installed on CF Cards: they are inserted into the PowerBooks via a PCMCIA/CF Card adapter. They all work great, and this is in no way a cause of the problem.
So does anyone know how to downgrade OS 9.2.1 - OS 9.1 when one only has (1) Full OS 9.2.1 retail install CD (2) OS 9.1 Update Installer???
Thanks.

Move the card onto a system where it is usable, and then run the patched version of the 9.2.2 update on it. The Mac OS 9.1 updater can't downgrade a 9.2 or newer system; that capability requires a Mac OS 9.0 or 9.1 CD.

Downgrade windows 8 enterprise to windows 7 enterprise under volume license and steps for installing windows 7 enterprise.

How to downgrade from windows 8 enterprise to windows 7 enterprise under volume license? and what are the steps for installing windows 7 enterprise?

The link provided by v-yamliu works good.
Steps for installing Windows 7 Enterprise can differ based on the method of installation.
Windows 7 Enterprise, being an enterprise product, is usually installed on PCs count of 20 and above. Also, organisations usually modify the standard installation image to suit the organisation's needs and policies. In doing so, they define the way the Enterprise
edition can be installed. They can be ZTI (Zero Touch Installation) or LTI (Lite Touch Installation). The following links will be helpful in this case:

http://technet.microsoft.com/en-us/library/dd919179(v=ws.10).aspx
If the above case is not true and only a standard image is being used, you can perform clean install as mentioned by v-yamliu. The following link will be helpful:

Yours is one of the moderate models and you will find links to all the drivers you need. My own take on this is you are going in the wrong direction. Instead of back to XP you should go forward to Windows 7, but XP can be made to work on that machine. Good luck and feel free to post back with any more questions.

How to downgrade BIOS on Satellite L650-11F

hello there,
i've just registered here but i've had my toshiba laptop for year and half now ,
it's L650-11F PSK1JE
my problem is the bios , i re-install windows every few months to keep the laptop fresh and fast and i download all new updates and drivers from Toshiba drivers page
well i did 2 updates to bios from 2.00 to 2.20 and then to 2.40
but since first update it seems to be messing my laptop
DVDWR stopped burning DVDs
Echo mode on battery don't setup says bios unsupported
Graphics card fails so much in games now in FPS and very slow rendering in the games !!
it's Radeon 5650 !
not the best card right now but it's very good 1 still ( Playing Aion btw ) .
i want to flash the Bios i wanna reset it to factury default or the bios comes with the laptop and i won't ever update it again ! it mess the laptop not improve it !
i read tutorials how to downgrade bios but i'd rather ask here for more pro help
thank you and i hope i get what i'm looking for i wanna reset this laptop and just download latest drivers

> i re-install windows every few months to keep the laptop fresh and fast
Many people think the same but especially fast has mostly nothing to do with BIOS update. If everything works well why to change anything and risk something.
My notebook is 3 years old and I use it still with original BIOS. No problems at al. Anyway, I think you should contact nearest Toshiba service provider and explain the situation. Be clear and tell them that you are not happy now and you want to have old BIOS version again. They have access to BIS database and can obtain older version for you.

How to DOWNGRADE 3G to 3.1.3

Anyone know how to downgrade? The Commander-in-Chief is already cursing how slow her phone is and doesn't think the new features outweigh the treacle. I've seen a couple of articles but with no joy.

I found this link for downgrading to 3.1.3 in Windows elsewhere on this forum. Maybe it will help? I'm going to attempt it this weekend as I'm not pleased with iOS4. Only thing is I'm afraid iTunes will balk when I connect the iPhone to it after the downgrade, as it has already done a Sync and Backup in OS4. Worst case I can copy everything over to my other computer and use the iTunes on it to restore all my music and apps to the iPhone. Basically reset it to factory specs and put it all back together.
http://www.ihackintosh.com/2010/06/downgrade-iphone-3g-3gs-ios-4-gm-to-os-3-1-3/
I have to say I'm pretty surprised at this. I'm a Windows guy and expect this kind of thing from Microsoft. That's why I still use XP. It works! I didn't think Apple did these kinds of shoddy upgrades! So I trusted the 4.0 upgrade! Who knew?

HDD failure, I'd like to know how to get Windows 7 back on it.

Hello everyone, I've had a HDD issue lately, but before I move on to describe my issue, here are the specs of my notebook:
HP Pavilion dv6-3264ca
AMD Triple-Core CPU 2.2 Ghz
6GB RAM
128MB ATI Graphic Card
750GB Toshiba HDD
Windows 7 64-bit
The issue:
Recently I've had a very unfortunate HDD failure. The recovery partition wouldn't even load. I tried booting my notebook on Linux with the HDD still attached, and it wouldn't read. I extracted the HDD and placed it in an HDD-enclosuer and it still wouldn't load on Windows XP or Vista or 7. It would however read in the device manager of Windows and also in the BIOS.
I needed to extract some high-priority data from there so I managed to retrieve all my data safely through a data recovery service, but now the drive is rendered useless. I was told a low-level format might be able to help it be usable again, and if that were to happen, the recovery partition would then be removed in the process.
In addition to that, I would like to install Windows 7 64-bit onto the drive, but the notebook box did not come with an installation CD, which is quite frustrating. Is there any way HP can let me download Windows 7 through some warranty service?
I have a one-year warranty on my laptop.
So in closing, I would like to know if I can get Windows 7 back onto my HDD for free, or if I need to go about buying Windows 7 again.
Any advice from you kind folks?
This question was solved.

Hi,
Here are Two options.
1. If you have ( or can borrow ) a retail Windows 7 installation disc that is exactly the same version as your OEM installation - ie if your notebook came with Windows 7 Home Premium 64bit this is the exact retail version you would need.
If you don't have access to a retail disc, you can create an installation disc yourself - just download the correct Disc Image from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD.
http://www.mydigitallife.info/download-windows-7-iso-official-32-bit-and-64-bit-direct-download-link...
Use the disc to perform the installation, enter the Windows activation key found on the underside of your notebook when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.
http://www.kodyaz.com/articles/how-to-activate-windows-7-by-phone.aspx
Any additional drivers you may need can be found Here.
2. You can order a replacement set of Recovery Discs using the link below - these cost around $30 if you live in the US.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00810334&cc=us&lc=en&dlc=en
If you have any problem with this link, order them directly from HP.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.
