Setup Installation :: How To Recover CD Key From UEFI
Aug 14, 2013
I have an ASUS Zenbook UX32V, which came with win 8 preinstalled.
I was having endless problems with Windows 8, such as software compatibility, and formatted the laptop (removing all partitions), and installing Windows 7 over it.
This has worked fine to date, but I now need to switch to Win 8 again.
I know my laptop supports UEFI, and that the Windows 8 installations are no longer probably on the computer. Is there a way to recover the cd key from the UEFI and use this to download the Win 8 installation files again? The CD key was not supplied in the laptop documentation...

First, some context: I have a Dell Inspiron 15R SE that came with Windows 8.
I've managed to get a working dual-boot system with Ubuntu 12.10. I can't remember exactly how I done that, but I remember that I had to disable secure boot. I think that the boot configuration those days was:
Secure boot: DisabledLoad legacy option rom: EnabledBoot list option: Legacy
This "configuration" worked perfectly for 6-7 months.
Then, one day (last week, can't remember the exact day), when I was using Windows 8 the computer crashed. I hard-rebooted and got this screen:
After executed boot-repair from a Ubuntu LiveCD dozens of times I've decided to eliminate Ubuntu temporarily and focus to get a system with Windows 8 working nice.
Then I used my recovery DVDs to recover the system. Yup, Windows has booted. But when I restarted first time I got the same error. Then I, digging a solution, pressed F12 after a reboot and got here:
The highlighted option allows me to boot into Windows 8. So I went to boot options (F2) and changed the following configuration:
Load legacy option rom: DisabledBoot list option: UEFI
Now I can boot directly to Windows without need to press F12.
But my objective isn't complete. I want to erase all Ubuntu entries from the seconds image and restore the legacy boot from the first imagem (because they worked before).
I did two things:
I erased all partitions related to Ubuntu (root partition and home partition).I created a Windows recovery disk (not a system recovery disk).
I used the recovery disk to run the automatic recovery procedure (I forgot the exactly name). I've runned it at least 10 times with no success. Then I went to command prompt to try the famous triad: bootrec /fixmbr, bootrec /fixboot and bootrec /rebuildbcd. Still, no solution.

My asus Laptop, K55N-DB81 has Linux on it. BUT before I had windows 8 on it. Now I want to re-install Windows 8 on it, but I don't know how to. I didn't create any recovery disks , and the Product Key is embedded into the Bios. I know what the Product Key IS just in case I would have to enter it again. Do I need to get an iso. to boot from and then go from there or something?

Went from an Intel MB and CPU to an AMD setup before realizing that wouldn't just be able to boot into my existing windows installation when I first plug everything in. From what I've seen on the forums I've decided to reinstall Windows 8 on the machine. The problem is that I need to recover the files on the old Windows installation. I have 2 HDDs to play with.
What should I do? Make a LiveCD of some kind and install Windows on a new partition? Make an Ubuntu LiveCD and transfer the files to the other HDD then install Windows?

I wanted to install w7 so i accidentally formatted some drives. then noticed i cant install w7 because of the gtp partition. as you can see in the pic partition 1 the recovery one looks like it wasn't formatted( i cant remember as i formatted the partitions 3 months ago) so is there any way i can use that recovery partition to restore windows 8
I have tried the alt+F10 menu. none of the following ways in the menu let me restore or reset the laptop. i tried all of the options in the picture none worked
So I am left with an laptop with no os how can i restore the pre installed Windows 8 or install w7 (i have a w7 cd)
The laptop is an aspire e1-571

I have an pre-installed Windows 8 in my notebook. When I first got the PC, I got only C:/ partition so I needed D:/ and for doing this I used EaseUS Partition Manager. This is just a guess but I guess Windows can't find those recover partitions that are in my HDD. I haven't deleted those partitions just created D:/ and here is a screenshot I just take to show you the partitions I have.
I have already tried copying the Install.wim from my BIOS_RVY partition which was about 9GB and I moved it to C:/WinRec and used this command as I saw it from internet : reagentc.exe /setosimage /path C:WinRec /target c:Windows /Index 1 But i still get the error:
"Insert media some files are missing. Your Windows installation or recovery medial will provide these files."
This method didn't worked so any other too. I wonder how can I refresh or some sort of return my notebook to the factory settings from the recovery parts I have.

I am clean installing Windows 8.1 and Ubuntu on a friends new laptop and although I have taken Clonezilla images of partitions on my personal laptop should I ever need them I was hoping there was something more user friendly I could install on my friend's laptop. Anarethos Recovery Toos with Media Creator seems to be what I am after but I am not sure if that will mess up the boot settings or even completely remove Linux.
Ideally I am looking for something that can be launched by holding a hotkey down at boot. When launched it will offer to restore the main Windows 8.1 system partition (GPT) with all drivers and programs installed exactly how it is when I hand it over, and if possible offer to restore the Ubuntu /home partion. The crux is that Windows can be restored without affecting Ubuntu.

I have two laptops, both Samsung, one mine and one my sisters. My one is Windows 8 and her one is a slightly older model so Windows 7. Now both are are very similar in spec, being 4GB and Intel Pentium 2.3GHz models. She recently asked me if i could sort out her laptop with Windows 8, so I said yep should be no problem.
I went and bought a Windows 8 Pro 64bit and was at first going to just do a plain install. But then had a bright idea and thought why not do an image of mine and recover it to hers, and then when started up just enter the key of the new one. that way she gets a full original Samsung install along with all the apps and everything.
At first I tried the samsung built in Recovery software but had no luck as it was just a complete nightmare. Not booting the USB I put it on for the first few times, then eventually after changing the BIOS setting to UEFI and formatting her Disk to GPT it started but then said no image found. In end I tried the old way by using the Windows built in File Recovery Image tool which made me a repair disc and 3 discs for the image itself.
This booted first go and went all way through the recovery, and then did the usual "restarting in X seconds ..." But after it rebooted to my horror the Samsung Logo screen appears and then after that it just stays blank.
It does every few seconds momentarily flicker on the screen but then just goes bank again. I cant even get into the BIOS anymore or boot from anything.

Here: [URL] .....
Somewhere in that link it says:
During POST enter "BIOS Boot Selector Menu" by pressing F7.
Intel says: <F7> No uefi setup option in boot selection
Others say: <F8> No uefi setup option in boot selection
I say: <F12> No uefi setup option in boot selection
Lenovo Z580, my brand new laptop that is, its UEFI based and vymrdal's ISO from MSDN is also created to be installed as an UEFI Install.

I reset my pc to factory conditions using the Samsung recover tool, the pc seems slower fps wise in games for example. Was faster before i reset the pc. Model Samsung 3505VC. I believe it might be to do with my graphics card as it is rated only 4.9 now on windows rating and was 5.7 before.

Is it possible not to have the partition "recovery"?
Because if you look at the two tutorials:
- UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
- UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with
In the tutorial to install Windows 7 in UEFI, there is not that damn partition recovery, while in the tutorial for Windows 8, we can see it.
When I install Windows 7 (MBR mode), I avoid this partition "recovery" by creating a partition with a name before installation. I install the OS on it and everything is fine, no partition "recovery" But here, since one must delete all partitions, If I create a GPT disk with a partitioning tool before installing, is that it might be appropriate?

Just a quick question about UEFI installation. I've got the Windows 8 Pro DVD but I lack USB Flash Drive 4Gb, is it possible to install Windows 8 with UEFI support with the DVD support or as written in the tutorial the USB Flash Drive is mandatory?

Is it possible to install Windows 8.1 as Legacy with MBR? Or only as UEFI with GPT? I'm kind of confused with all this UEFI business, I always used MBR in my Windows installations. Also, Truecrypt does not support UEFI, so if installing Windows 8.1 I should do it as legacy.
Also, how can I control during the install process if I want to set my system installation as UEFI or Legacy?

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.

I've made a UEFI Win8PE by WADK , then burn it to a CD. I boot normal and I can see X:WindowsSystem32.
I use EasyBCD to [Add New Entry] to append new boot item to existing Windows 8. The boot menu becomes like this :
Windows 8
Win8PE
But the Win8PE fail to boot with error message like insert Windows disc again ...... in the primary black and white screen.
Should I not to use EasyBCD to [Add New Entry] ? As I do the same thing in BIOs + MBR harddisk that booted perfect. In UEFI + GPT partition , do I better not to use EasyBCD , instead to use BCDEDIT , if so , what's the command line to do this with bcdedit ?

I have windows 8.1 installed on 120gb ssd. I also have a 1tb HDD too. So I was trying to install Hackintosh/Linux when I noticed that the System Reserved partition was on my HDD instead of the SSD. So, I used easybtc to migrate my boot files to my SSD. I deleted the system reserved partition. Now I want to convert my BIOS to UEFI. I have Z87 pro mobo.
I tried this tutorial: [URL] ....
But it seems to be geared at the C drive, where I don't have room for that 350mb as disk utility wont let me shrink it.
Edit: would downloading a third party partitioner, shrinking C about 350mb, or whatever is the minimum, and then use that new space as described in the guide work?

I have an Acer Aspire 5745G-644G50MNKS notebook with preinstalled OEM win 7 home premium.
Specs as following:
Core i7 640M Processor (2.87GHz, 4MB L3 Cache)4 GB DDR3 RAM500 GB HDD15.6" 16:9 HD LED DisplayDVD RW1 GB VGA (NVIDIA GEFORCE GT 420M)WIFI / Bluetooth / Card Reader / Web Cam
I'm wishing to update my system into Windows 8 Pro or Enterprises. But unfortunately my model isn't appears in Acer's Windows 8 Eligible Models list or Affected Models List.
I think my system has more than enough performance to run Windows 8. But my bios don't have UEFI support. So, i just wanna know will my computer be able to run Windows 8 without any troubles without that secure boot option.
I"ve run Windows 8 Upgrade Assistant Tool in my system and it says everything is okay except Secure Boot option. also I'v checked individual hardware vendor sites for the latest drivers for windows 8. Most products has the drivers, And the current drivers also compatible with Windows 8 according to the upgrade assistant.
What should i do so? Will the win 8 upgrade useless in my system? or it will be better than the current win 7?

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 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 have original ISO file from MSDN website - it is Windows 8.1 Update 1 Enterprise (x64) MSDN version with Slovak language interface. I create a bootable DVD (Verbatim DVD-R 4,7GB) in program ISO2Disc. This ISO I would like to install on to my system , more details about my pc - see my system specification. My motherboard is MSI Z77 Mpower with latest version UEFI - BIOS 17.12
I have a few question about installation a new windows 8.1 in uefi mode:
-what a bootable media is better ? I think USB stick or DVD disc
-what the function in the BIOS I must turn on or off, I mean the fast boot or memory fast boot
-UEFI mode is better then LEGACY mode ?
I have a bootable DVD Parted Magic , it is good Partition Manager. I must change MBR format to GPT - only GPT is supported format for UEFI , is it rue ? So , now i should format all disc inside my pc (secure erase for ssd disc and wipe for hhd). I can create NTFS partition with GPT format and aligned to 1204MB for all solid state discs and HDD. I can do this ?

My notebook has a Win 8 OEM key in UEFI. After wiping my hard disc I want to install Win 8 retail instead of OEM version.
Because this is not possible with stored OEM Win 8 key I want to boot with a Win 7 BootCD and patch the UEFI with a Win 8 retail serial key.
For that I need a Program like SLIC which accomplish this task.
But where do I get this SLIC tool?
is there another way to enter a new Win 8 key into UEFI from Win 7?

I would like to reinstall Win 8 on my ASRock UEFI motherboard in the UEFI mode. I have Win 7 OEM and the downloaded Win 8 Pro upgrade. I have the Win 8 Pro upgrade burned to an ISO disc. I also have the hard drive backed up to Acronis 2013 and have an Acronis WinPE rescue disc to boot with to restore.
Several questions.
(1) If I convert to UEFI and format the drive to GPT, will Acronis restore to the GPT (from MBR)?
(2) If Acronis won't restore, will converting to UEFI/GPT affect installing or activating the Win 7 OEM and/or the Win 8 Pro upgrade (I assume I'll have to install Win 7 and then upgrade to Win 8).
(3) Will a UEFI system read other hard drives that are MBR formatted?

Laptop: ASUS UX31A-DB71, latest BIOS: 218
Originally my laptop came with Windows 7 and when i looked at disk management my disks were formatted with UEFI schema. One of my friend gave me a UEFI bootable USB drive loaded with Windows 8. So, i thought why not give it a try. So, I created a backup of my OEM Windows 7 and saved the iso files in a seperate external HD (created twice just to be sure . Now, i decided to load the Windows 8. Booted into the BIOS and there is an option to select the USB drive along with the UEFI option for that USB drive. I selected the UEFI option but some reason it does not boot into UEFI.
So I decided to select the standard USB install and this option let me install windows 8. In the process of installing i formatted the partitions and made a single partition and installed Windows 8 on it. I am guessing now the drive is not GPT but MBR. I also noticed that his installation USB disk had an option to select either 32bit or 64bit of Windows 8... Would Microsoft create a same iso file with both versions? I am guessing he created the USB from a illegitimate source.
I am planning on purchasing Windows 8 Pro version as an iso but wanted to be confident that it would work with UEFI architecture.
Questions:
1. Why would the system NOT boot from UEFI?
2. If I download the legitimate iso from Microsoft and wanted to install Window8 Pro via UEFI, I am sure i would have to format my SSD to GPT and how would i go about formatting it during installation?
3. How would i create a recoverable USB for my iso image i created for Windows 7 via ASUS AI Recovery. Do I need to follow the same procedure as stated in creating bootable USB disk (i.e. FAT32 system) via diskpart utility?

Have any of you successfully installed Windows 8 with UEFI on a RevoDrive X2 (PCI-E express card)?
It starts the installation just fine for the RevoDrive X2 after loading it's drivers, but on first restart it...:
No boot drive found.Manually select to boot from the RevoDrive from the boot menu (F11), and it just restarts the installation again from scratch.
It installs and runs just fine with legacy BIOS (MBR) for the RevoDrive X2.
It also installs and runs just fine with UEFI on an internal SATA2 HDD.
Things I've done:
Bootable Windows 8 USB formatted as FAT32 w/EFI folder in itEnabled wake on PCI-E/PCM in UEFIBooting from USB from boot menu (F11) and not set to always boot from USB.

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?

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.
When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

I just install windows 8 using BIOS , but now i want to change it to UEFI boot. so i followed steps below
1.create and format a new FAT32 partition K:
2.my windows8 is in I: so , i use this command bcdboot i:windows /f all /s k: and succeeded.
3.i checked with the bootice about the BCD in my K: and found it indeed point to i:windows just like the picture below [URL]
4. and i restart, choose uefi boot in BIOS configuration and it showed like this: [URL]
5. i checked my k:/windows/system32/ , there is a winload.efi file... [URL]
The most strange thing is that i've copyed my winload.efi to other computer which is already in UEFI mode , and also i've copyed it in my virtual machine, it works fine! So my winload.efi should be OK.
