Setup Installation :: Using UEFI USB - Clean Install Of Windows 8
Feb 12, 2013
I have made a clean install of Windows 8 using USB and UEFI. Somehow it seems the instalaltion is not quit right of what I have read... Have attached picture of the Diskmanagement (OS is Norwegian by the way).
Compared to this thread: UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with for me something is missing/wrong.
I have a laptop with one SSD and two internal disks. Both internal disk were removed before the installation, and connected and formatted after finished the installation.
It can me mentioned that I downloaded the OS, saved it as .iso file, then copied onto the USB disk. Then connected into the laptop and booted from USB/UEFI.
I did not follow these steps: UEFI Bootable USB Flash Drive - Create in Windows

I recently bought a new SSHD for my laptop and after initial problems with trying to install Windows in UEFI, I turned to Legacy and that worked. But now when I change it to UEFI, it just comes up as "Operating system not found".

After reading many threads about this UEFI stuff, i'm confused. I have a Asus Sabertooth z77 motherboard and will be fresh installing windows 8.1 full to Samsung 250gb ssd. I'm not quite getting what i'm supposed to configure on the MB for UEFI boot prior to installing the windows 8.1.

I just got a new laptop, a Lenovo X230, for which I paid extra to have the OS on it as Windows 8 Pro.
So--now I have it, and Win 8 Pro 64 is installed and activated on it. I am a legal owner of Win 8 Pro.
However, I would like to do a clean install of Win 8 on the computer, to have it free of bloatware, etc. (In fact, I would like to set up a multi-boot with Win 7, and perhaps even triple boot with Xp as well. (I have installation media and my product keys for XP and 7 though, so those are not really a problem.)
The computer came with no discs at all. There is a procedure to make recovery disks. I may do that, but I think those will be to restore the computer to how it came from the factory, and therefore not usable for a clean install.
I don't see my product key for Win 8 anywhere. Not on the computer, not on any kind of card that came with it, etc.
I looked at the tutorial here for clean install of Windows 8, but it requires an install disc and product key. I have neither, although I am a legal owner of Windows 8.
Is there a way I can create (from my installed Windows 8) a win 8 install disk, that can be used for a clean install? Or a link to download one? Is there a way I can get my product key?

How windows 8 works now without the sticker key on new laptops. I've searched all over the internet and all I can find are dumb articles telling users to use the manufacturers recovery image. How to do a CLEAN install of Windows 8.
My new windows 8 has NO sticker key on the bottom so my understanding is that it's stored on the bios? Is this correct? So my question is, is if I get an ISO of windows 8 and install it, will it automatically recognize the key or is the key only set up to be recognized by the PC manufacturers crapware filled image?
ALSO, if thats the case, can I use a 3rd party product to pull my key and then use that with the clean ISO? Lastly, where can I download a clean ISO of windows 8? I know you can download official windows 7 ISO's, but i cannot seem to find an official windows 8 iso. I have no desire to download a torrent or from some shady website, I just want an official ISO.

Until very recently i was running Windows 8 with a 240 GB Sandisk SSD as a primary and a 2 TB Western Digital Green HDD as a storage. I decided to set up a RAID 1 setup so i purchased a second 2 TB HDD and installed it.
My intent was to run windows 8 off the 240 SSD as a primary and have a RAID 1 setup for my 2TB HDDs.
I learnt that my data configuration was set to AHCI. I decided to do a complete clean install and change the sata configuration in BIOS to RAID.
After successfully creating a RAID volume using my 2TB HDDs i proceeded to install Windows off my primary. I am however having difficulties in that it will not allow me to install windows on either drive.

I bought an acer 756-2808 netbook last year with windows 7 from Amazon. This netbook came with a "upgrade to Windows 8. SoI did the upgrade when it was released.
Sadly, I probably only used netbook for a month or two because the LED screen cracked. They are pretty fragile.
Then, I upgraded to 8GB ram. This thing flies!
I downloaded 'produkey' from nirisoft.net, because I can't find the product key anywhere for the life of me.
So, now I have the product key for the current windows 8 installed. Will this upgrade product key work for a clean install? Moving on, I ordered a Samsung 840 Pro 128 GB which should be arriving in a few days.
Finally, I want to do a clean install of Windows 8.1 using a Windows 8 Product key. Is this possible? The original HDD on this netbook has nothing on it, so I don't really have to back anything up either (like I said I barely used it for two months before the screen cracked!)
I did some searches and found this link: [URL] .....
So if the above step is correct.
Do I:
1.) Get the ISO on the USB following the steps mentioned in the link above.
2.) Take out old HDD and install new SSD
3.) Reboot computer with USB
4.) ?
5.) ?
6.) ?
etc.
Are these steps incorrect?

I have a Lenovo B575 laptop that is not UEFI capable; however, I have downloaded the x64 Win 8.1 ISO, burned it to a bootable DVD and a bootable USB drive and tried installing Windows 8.1 using a boot from DVD and also a boot from USB drive, and neither method has resulted in a successful installation. The root cause of the installation problem is that Windows 8.1 is intent on creating an EFI partition structure on my non-UEFI machine.
So, I end up with a 300MB Recovery Partition and a 100MB EFI Partition which doesn't work well on my machine. Now, during the installation process, I opted to delete all existing partitions and allow the installation to properly partition the hard drive for installation; however, I knew I was in trouble when the machine started hanging during reboots.

I have just recently bought a new computer. If I knew I was going to have this issue I probably wouldn't have bought a 4TB HDD but anyway.
What I have done is read the article (this is where I found out I couldn't install to the 4TB HDD in the first place) on how to install Windows in UEFI format. I have created a USB flash to do this but still my HDD partion is only showing up at 1.6TB. It is setup as a GPT file format as it gave me all the prompts and created the Recovery, system partitions etc. How do I get this to work so when I do the install it shows up in the first place as the 4TB partition or at the end of it all is still not possible?
What I will be doing is installing Windows on this 4TB patition and then using a 256GB SSD in SSD Caching.
Am I better off getting a 1-2TB drive and installing normally instead of wasting my time or can this be done?

I built up a new PC featuring a brand new SSD (i.e fully unallocated). Then, I made a clean install of Windows 8.1 pro (64bits) using an ISO DVD. Using Windows disk management tool after the install, I can see that only two partitions have been created: one System partition in NTFS (350MB) and the remaining of the SSD is the C: partition while I was expecting a third one : a recovery partition. Of course, I do not remember a prompt during the install to ask whether I want a recovery parttion or not.
Is it normal ? Is a recovery partition useful knowing I have the install DVD ? If the recovery partition has some advantages, is there a way to create it after the install is completed ?

So my windows 8.1 installation became corrupted, so I backed up data and did a clean install after deleting all partitions.
After the install on the first boot, right after the process of "installing apps", it showed an error message saying an error occurred causing windows to restart, and created a memory.dmp file.
I just want to make sure this installation is stable before continuing to update to 8.1, especially after my previous issues. There are also some errors in the event log that I don't understand.
The errors came after install of Windows 8, as that was the key I had.
Windows failed to download and install 92 updates with error code 80248007

I upgraded to Windows 8 from XP via unlock key without CD, forgetting that it'd be 32bit too.. I'm making a rebuild soon and I think 64bit would really benefit me, apart from some programs I use that are being discontinued in 32bit. A friend of mine recently upgraded to Win 8 too, but he bought the CD. Could I use his CD to overwrite my Win 8 32bit with a 64bit one? And another question: if I could (and I hope I can) is there an option during install to leave some free space for Linux? Having Windows 8 only is not safe ..

After BIOS page passes, it loads for 10 seconds and crashes. Error screen disappears too quickly so can't take note. This is a new laptop.
Have tried 64 bit Windows 8 ISO and from Flashdisk.

I have bought a Dell Inspiron 15R which arrived this week. I have already decided that I am going to install my own copy of Windows 8.1 Professional on to my system.
I have tried this several times now and I keep failing. I am booting from my DVD and the install goes fine. However during install I am normally prompted to enter my Serial for 8.1 and it does not do this. It progresses as though everything is ok, I can format the Hard drive and then it proceeds to install Windows 8.1.
Once fully installed I then go to see if it is activated and to my surprise it is. It has activated with the same Serial as the OEM that came with the laptop.
I have also noticed that this copy of 8.1 cannot join the laptop to my own domain (the options to do this are greyed out) which I am also wanting to do. So this copy of 8.1 is not the copy I am trying to install.
How can I install my own copy of 8.1. I think this is something to do with Dells bios configuration but not sure where to start.

I have recently purchased Windows 8 Pro Upgrade and for Christmas I will be getting my first SSD.
I want to do a clean install of 8.1 via USB, is this possible with the Windows 8 Pro Upgrade key? I have read through numerous tutorials and think I've got it right but just want some to clarify this will work.
Download the 8.1 ISO
Use the generic key to run the installer
Setup the PC
Open PC Settings
Change Product Key enter Win 8 Pro (upgrade) key and activate
Do I then need to do the reg edit and command prompt changes? Regedit - HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE Command prompt - slmgr /rearm Do I have this right or am I missing something?

Ive just done a clean installation of Windows 8. I checked device manager straight away. There was a listing under Other Devices with an exclamation mark listed only as "Media". Ive never seen that before so I havent a clue what it referred to. When I clicked on its properties it said Internal High Definition Audi Bus. Was this a serious issue..maybe a corrupted installation?
I wasn't sure what to do but because I had installed from Windows CD and not factory image I had to go to the Dell site and then install the Intel Chipset software. I then rebooted. The Media icon and exclamation error then disappeared from Device Manager.
Was it the Reboot of my PC that got rid of it or was it the Intel Chipset software being installed that sorted it out? Also what is "Media" referring to or is it just a generic term? Also, Im always confused as to what is the difference between an exclamation mark and the blue question mark on a white background in Device Manager which Ive seen before too?

Right now I have an asus h61-le-CSM motherboard with EFI; it's a little older with a i3 2120 processor. On Friday I'm upgrading to a Gigabyte GA-Z77X-UD5H with a i7 processor.
Right now, I have windows 8 installed. I believe I purchased the upgrade version, although the receipt from microsoft in my e-mail has no mention of the word upgrade, it just says Windows 8 Pro. I am going to want to do a clean install with this stuff which I am capable of doing, however I don't know what I need to do to keep Windows. Will I be ok just re-entering my key?

I read about how to upgrade from 32 bit to 64 bit with clean install. I have a 32bit win7 on my desktop and a 64 bit Windows 8.1 on my laptop.
My question is can I use the Windows 8.1 laptop do download the upgrade assistant and get Windows 8 64 bit? I don't want to screw up my laptop especially cause it has an OEM Windows 8 that how to reinstall in case of OS breakdown.
In case this is not possible, is there any way to get a 64 bit Windows 8 upgrade downloaded without another 64 bit os already installed?

I purchased a Lenovo Y510P laptop over a month ago which came with Windows 8.0. and I hated it from the get go. I was aware that 8.1 was available as a free download so I downloaded and installed it. All of these updates seem to have bogged down my system. When I click on what I am assuming is the new start button (the white house icon in the taskbar) it takes 6-10 seconds for the menu to appear .
I dug out the key with Belarc advisor and went to MS's site to download an ISO of 8.1 but it told me that it would not let me download the 8.1 ISO since my key was for 8.0. If I were able to get my hands on a 8.1 disc would I be able to use my 8.0 key to do a clean install of 8.1? It is so disappointing to have purchased such a powerful laptop and have it bogged down by so many updates as well as all of the bloatware that came preinstalled on it.

I have a Dell Inspiron 15R SE 7520 laptop that came with Windows 8 Core edition pre-installed. This laptop has never worked properly for some reason. It won't shutdown the normal way (it'll just stay on the shutdown screen forever) and it never comes back from sleep without a BSOD along with other troubles that haven't been solved by updating drivers,etc.
I decided I want to do a clean Windows 8.1 re-install and upgrade on my laptop to get rid of these problems, but it's been ages since I last did this (back in Win2K times, I used to dual boot Slackware Linux) and I've bee reading about all this UEFI, Secure Boot,etc and quite frankly it's making me quite nervous. I was even planning on taking this chance to dual boot some linux distro, but it looks sooo difficult. Things are much more complicated these days for the tinkerer!
I need to make sure I can get back to a running system quickly.
For starters, here is how the hard drive is partitioned: [URL] ....
And this is the Diskpart output : [URL] ....
Why do I have 5 partitions? I understand the recovery partition, the OS partition and (after lots of reading) the ESP partition, but I'm not sure about the others. What do I need to keep? I've been reading around and I see some people recommend wiping the whole drive and starting from scratch. Is this a good ide?
I'll create the installation media from a windows 8.1 MSDN ISO using a USB drive. When I start the installation process it will ask me where I want to reinstall it to. Do I just choose the OS partition? Won't the recovery partition be based on a Windows 8 image and be useless from now on?
What's the best way I can get back to a fully working system in case I screw up somehow? I've made an image of my drive using Macrium Reflect free edition. But I read here that I cannot make an image of a GPT disk. Will this image I made work for getting back to a working system quickly in case I screw up?
As a last resort, I've made a Recovery USB using the Dell Backup and Recovery Method. In the extreme case that I screw up real bad, will this work to get back a factory-state system even if I've wiped my hard drive clean? I'm assuming this tool is for users recovering after a dead hard drive so it should work , right?

I have a Windows 8.1 Update 1 ISO and would like to use it to perform a clean install on a system which supports UEFI Secure Boot but has no optical drive. What would be the best way to approach this?
WIMBoot would be nice to have as well, if there's a way to do it without making things too complicated.

using the UEFI install instructions from this forum. I do meet all of the requirements (Windows 8 64-bit iso, ASRock Z87 Extreme4 mobo, blank SSD). When I get to Step 7 in the UEFI guide, I only get 2 partitions instead of the 4 shown(Recovery, System, MSR, Primary). I only get System and Primary. I decided to delete all partitions and just run the setup on the unallocated drive...everything worked fine. I am just wondering what the consequences are of not having those 4 partitions. I still have the UEFI interface when I boot up so it appear that is working.

Last year I built a new computer (ASUS Z87-Pro), andinstalled Windows 8 Pro 64 bit with an OEM DVD purchased online. Then upgraded to 8.1 Pro via the MicrosoftStore, and later purchased and installed Windows Media Center. The original Win 8 installation was done inlegacy BIOS mode instead of UEFI. I nowwant to do a clean install in UEFI mode. I of course have the original Win 8 Pro product key, and also haveextracted the current product key from the registry using one of the manydownloadable tools. Neither the currentor original key is embedded in the BIOS.
I would like to avoid reinstalling the original Win 8 Pro,and upgrading through the store. What Iwould really like to do is download Win 8.1 Pro Update 1 64 bit iso fromsomewhere, and burn it to a DVD. Canthis be done with the product keys I have, and what would be the product keyand activation steps?
