PC Downgrades to Windows 7 Vary Between OEMs

Acer, which also sells Gateway branded PCs, says that if it offers Windows 7 as a downgrade option, then it will fully support the drivers and hardware. In other words, if Acer doesn't offer a Windows 7 downgrade option for your PC then they won't provide Windows 7 support.

I had the same issue. You need to go in to the UEFI (BIOS) and change the boot settings. I ended up using an external USB DVD drive to boot from as UEFI did not seem to recognise the in-built DVD as a bootable device.

Since you've decided you want to bypass UEFI, here are the steps which resolve most install problems:

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. Do not modify any files on the stick if using Legacy install. If in doubt rewrite the stick using UltraISO Software To Create Bootable USB Flash Drive

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Windows 7 Ultimate 64bit

I've installed Win 7 x64 succesfully, skipping UEFI and did a clean install/re-install just like the gregrocker tutorials suggested, I followed every step, and the correct drivers are loaded too, but the problem is that, after that I use Windows Update, and the updates like language packs, virus removal tools and updates for internet explorer seem fine, but when it comes to security updates for the system, the computer restarts and the boot at "Starting Windows' screen takes like 30 mins, and the computer itself becomes almost glacial, everything is slow as hell, I can't even open programs, and I'm pretty sure it's the updates because that's the last thing I did. Before the updates everything was fine and quick, but the updates seem to hang the system. Any suggestions?.

Did you take the drivers from WIndows Update only, after enabling Automatically deliver drivers via Windows Update (Step 3)?

Which drivers were missing in Device Manager after all rounds of Updates, and where did you find them?

I'd System Restore backward until you find it working satisfactorily, then take a look at what is left to install and do those Updates in smaller groups, testing performance after each.

This alone may solve it, but if it bogs again then Restore again and install those suspect Updates in that last batch singly to isolate the problem Update, post it up here for our Updates experts.

Windows 7 Ultimate 64bit

No, I downloaded them directly from the manufacturer site and all was working perfect (graphics, audio, lan/wlan, bluetooth, camera), none of which were missing from the manager, not a single error regarding drivers. In fact I installed a couple of language packs (english is not my native language), and the virus removal tool and it's definitions, and also a couple of updates for IE as well Net 4.0. At that point all was fine, but then I wanted to install the rest, they were all about system security updates, and that's when it got scary, because it would not download so I searched them in the catalog online based on their KB number and installed just 3 of them just to test, and when it restarted, the Starting windows screen just hung up, and when I tried to boot in safe mode, it got stuck at classpnp.sys. So yeah, before I installed any of that update crap, I did a recovery disk with Redo Backup (excellent program by the way), so now I'm gonna try to go slow with this, a couple of them at a time. Again, thanks for the help guys I really appreciate it.

Win7 is a driver-complete OS in the installer and via Windows Updates which does not require XP and earlier methods of changing out a bunch of drivers. Win7 chooses the drivers it wants.

May I suggest you start over and this time follow the steps in Clean Reinstall - Factory OEM Windows 7
which always results in a perfect install.

The problem with drivers through Windows Update is that it doesn't detect all of them, it just found a driver for the graphics and that's all, and about the clean install tutorial, I must say it relies too much on windows software by itself, for example, the windows recovery disk (like the burning tools) are kinda underdeveloped, it was much better and easier and faster to use third-party applications, because the windows recovery by itself gave me errors and issues whose only solutions I saw in other posts (even here on 7forums) was to use a third-party app. All the other steps I followed through completely and some of them were really helpful. The ONLY real issue I have here now are the updates, now I'm unsure of what updates do I have to install, and looking through other posts here too, I'm not the only one experiencing problems with this (at least on x64).

Did you enable Automatically get recommended drivers and updates for your hardware (Step 3) and run all rounds of IMportant and Optional Updates immediately after install? Apparently not if you're now asking which Updates you should install.

Always install all Important and Optional Updates unless they clearly don't apply to you. It isn't necessary to pick and choose or fear Updates at all in Win7. This is outdated XP-think. In the one-in-a-million case where Updates fail just System Restore to the point they set, if necessary from the booted Win7 DVD or Repair CD System Recovery Options.

I don't know what 3rd party repair tools you're referring to. Perhaps you could explain a bit more which tools were applied for which problems. Many of the most effective repair steps that have worked best since before Win7 was released are compiled in the repair tutorials in my signature pic below.

Ohh nevermind, I'm sorry, you were right Greg, I guess the problem was even more serious than just software. Turns out, the HDD has some bad sector problems, according to the Seagate tools for windows, it says it failed to pass a Long Generic test, and that I must run Seagate tools for DOS. Well, since this problem now has nothing to do with the OS anymore, I guess I should now close this thread?. Again, thanks everybody

I would confirm the HD condition by doing the Seagate extended CD test followed by Disk Check done on a whole disk partition you create using the commands I gave you earlier.

Use Option Two for Disk Check from Win7 installer's System Recovery Options Command Line.
