New lappy came with windoze 8.1 and I just assumed I'd be able to bring it home and wipe the HD and install widows 7--but so far no luck.

(Tried searching the topic here and though I got quite a few hits, when I clicked on them I kept getting 404 error messages).

Read somewhere a suggestion to enable Legacy Boot Mode but all boot mode options are ghosted in the BIOS. Apparently this is a UEFI hardware machine that puts up a fight when you try to "downgrade" the OS.

No offense to microsoft but 8.1 is truly the worst OS I've ever used and I'm hoping I can get it off my new Toshy laptop and install Windows 7.

Thanx for the width,

1. format HDD to MBR/NTFS
2. re-install windows 7
3. ???
4. profit.
 
Pretty much what Same_text said. the UEFI won't stop you from installing software onto a hard drive. Just sack in your W7 Disk, boot of it and install! I've performed a windows 8 downgrade to 7. All you need to do is format to MBR (again like sample text said) And reinstall drivers from manufactures website. Simples.
 
Well, the above is what I thought I could do and perhaps the mistake was my procedure. I went ahead and let the machine boot into its 8.1 installation then inserted my Win7 dvd and invoked the install procedure from there.

It did the initial win7 file copying and rebooted but then popped a black screen saying the software I was trying to install was not digitally signed. One of the offered boot options then was windows setup--but clicking this just brought back the same warning and I went round and round and eventually chose the other option which was win8.1.

Managed to get to the bios and chose the cddvd drive as the boot priority and shut it off and tried again but it will NOT boot from the windows 7 dvd.

Thanx y'all for your responses; I'm encouraged but I'm not out of the woods yet.

Best,
m
 
Just want to offer my sympathy, mondo. I ordered a new Dell 7000 and attempted the same thing. In my case, Windows 8 UEFI boot won't even recognize a Windows 7 Professional (brand new) Disk. Dell Technical Support, normally very good, is not willing to offer any help with this. Seems like Microsoft is deliberately making a change back to Windows 7 difficult in the hope that we will eventually give up and just accept W 8/8.1. Hardly surprising that Dell, now owned by Microsoft, is unwilling to help. (For the record, Microsoft acquired Dell when Dell was planning to offer computers with Linux OS onboard). I have purchased 12 Dell laptops over the years and have always been more than happy but this could be the last one ever, and I still have a week to send it back and get a refund.

In the end, Dell may become a casualty of Microsoft forcing Windows 8.x on us. That would be a shame.
 
OK sorry I didn't post back to the list that I finally was able to do this (wipe 8.1 from the HD and do a clean install of windoze 7 ultimate 64bit on a new Toshy laptop).

So don't give up! It's our money and our laptops and we have the right to choose what operating system we run.

This whole walled garden nonsense that Mac users seem comfortable with and that microsoft has realized is a great way to further control its user base is unconscionable--and if you do any reading on the windoze 8 and particularly 8.1 phenomenon, you'll see that lappy sales dropped drastically because of this. (Gives me hope that consumers realize how much power they have to affect change).

And this obsession with mobile--if I want mobile on a larger screen I'll get a tablet but leave my computer alone!

OK, rant off, here's what I did to the best of my memory--god when will I learn to take notes?!? Used the following links and did a cherry pick of the workable options from each of these videos:

Obviously with windoze 8.1 the biggest challenge is to get the machine to boot from the windoze 7 install disk and that's what those yutoob vids help you with.

Memory serving, it had to do with enabling/disabling the uefi stuff, the legacy boot options and the like in the bios. Sorry my post isn't more precise but this machine is no longer on site as I did this for a friend.

Keep at it and you will be able to get the lappy to boot from the windoze 7 disk and at that point you can reformat the drive to wipe away windoze 8 and do a clean install.

Discouragingly, if you google this topic you'll find pile upon pile of so-called experts who claim it can't be done--or else responses like the ones here which assume you can boot from the windoze7 DVD when windoze 8.1 does all it can to make this impossible. I'm just glad I didn't take no for an answer.
 


The UEFI setup won't let you boot to a different system (I tried Win7 and Ubuntu Linux). After a while it actually removed booting to DVD from the settings. It just went away as an option and only the hard drive was listed.

If I managed to get the DVD to even boot, it would just bomb out and go right into Windows. I never did figure out why the DVD boot option went away? I took the laptop back to Fry's and got rid of it. I then found a much better Dell laptop for $200 cheaper in a pawn shop that came with Win7 Pro and was in perfect condition!
 
Hey straybeat, though I'm sorry you were unable to do this I'm tickled you took your lappy back; more people who do this the stronger the message to the manufacturers NOT to install windoze 8 on new machines.

But I assure it is possible to get rid of 8.* and do a clean install of win7. As mentioned in my earlier note, I'm only sorry I forgot to take explicit notes but I was able to do it on my friends new Toshiba. Memory serves, it was definitely two or three or perhaps more settings in the bios--and not just uefi--that then permitted booting from the DVD drive. The tricks were definitely revealed in at least one of the videos I linked to in my previous post.

Windoze is assuredly trying to lock us in to a specific OS and the more of us who resist the more they'll realize that if we wanted to be mac people we'd go to the silly store.
 
Look at the 3rd video it works just did now with a toshiba satellite c55

I just ordered my windows 7 to install over 8.1. From everything I have read you just disable fast boot and secure boot and change boot device from Uefi to CSM...and select cd drive then. I am thankful my bios has the option of not using Uefi so I'll let u guys know if it works.

I will not purchase another computer with an operating system on it. I want to always have a choice!!!
 


Sam, What happened in your Driver situation? Did the computer eventually function with 7? Please tell.

"I hate windows 8." A good rhyme!
 
Sorry this isn't a solution, I'm having this problem myself and just found this thread, and it looks promising so I'll have a look and return again with further updates on my attempts. Although I have an HP laptop, as opposed to the Toshiba one, and my BIOS is just plain blocked to me... I've only got like 3 or 4 changeable options in there.

But this is primarily a message to SOREATMICROSOFT...
I see where you come from. This system is completely unnecessary and completely frustrating, and as a tech-geek who has simply been surrounded in constantly failing, and easily broken, technology for the past 12 years or so, I'm with you on the point that Microsoft really need to get their heads together. Ever-swapping software and hardware instead of fixing what they currently have to make it stable and usable isn't a solution, let alone a temporary and/or permanent solution... However,

Your statement below is still uncalled for. You do realise that the people who created Windows 8 and 8.1 did so because they were being paid to, right?
Not every piece of functionality in the OS is under their command, and sometimes these functions come through an unexpected turn of events. I won't say that Microsoft are innocent of the action of restricting users from bumping 8/8.1 for an earlier version of Windows, but losing your cool like that isn't worth it.
You're not changing anything by throwing your mind, fingers and keyboard(s) away with how hard you were probably hitting the keys.
If you lose control, you make mistakes. If you make mistakes, you get punished for it. If you get punished for it, your only defense is to stick with the reason why you lost control. And if losing control over something you technically have no say, no position or no power to change (regardless of the masses that join together to demand change), it doesn't make you innocent.

Keep your cool, man. Just accept it. All technology is reaching its dead end by constantly being replaced when something stops working, and the replacement sacrificing 20 things that do work for 1 thing that doesn't. Work yourself around the system that fails, because you'll never get it better than what you have now... Maybe the older generation, but not now.


So yeah, points to be understood,
--Technology fails because it's always being replaced instead of fixed
--Not everyone involved in the division of Microsoft's Windows 8 are to be punished, regardless of how you feel (it's being prejudiced)
--Bill Gates is a money-grabbing thief, but was the one to invoke the creation of your favourite Windows OS', so you can't hate him indefinitely
--Losing control gets you nowhere, but blind to all sides, and those with control will ALWAYS back you into a corner until they crush you... And I doubt you wanna be part of Microsoft's Legal Department smoothie recipes.


Chill home-dawg. We're all in Noah's E-Ark here, won't help to rock the boat rather than help it stay afloat where possible :)
 


Go to setting->advansed->boot menu ... change boot menu from UEFI to CSM Boot.

guise this may help you.
 
I found this entry that works. I've tried it. It is really a simple thing to do.

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) 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.

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

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

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.
