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.
After creating a UEFI bootable USB thumb drive with Rufus (using Windows 8.1 Enterprise ISO x64), for a Dell Optiplex 3010 (configured as UEFI only, no CSM, latest firmware version, Windows 8 installed), I didn't see a USB boot option, so I tried to add one manually. Unfortunately I erased the existing boot option (boot manager) by mistake. Although there were two boot options for PXE booting, the machine will not start anymore, even when there is an active WDS server on the network.
I also see Led's 2 and 3 lighting up, meaning according to the manual 'hardware ok but bios possibly damaged/corrupt'.
I understand I cannot start the machine from a bios boot disk because of GPT partitioning, and the UEFI USB boot disk I made might be corrupt (as it didn't show up as a boot option), however I don't understand why it won't boot from the PXE network card, as these boot options are still there.
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'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 ?
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?
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.
I've downloaded a legal iso from MAPS, i ve slisptremed all latest updates into it with Windows download integrator (it uses dism afaik) , then the problems comes in - i cannot use USB as my install.wim is 4,8 GB. I ve burned a Dual layer DVD with Windows 8 stock recorder and the PC doesnt see the DVD drive as bootable. When using stock it boots uefi from pendrive without any problems. How to make this updated iso boot into UEFI mode ?
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".
1st partition is Win7 SysPrep and the 2nd partition is Windows 8.1 Sysprep. I install Win7 and press Ctrl-Shift-F3 to form SysPrep, same as Windows 8.1 in 2nd partition. I made this becuase I've 25 Dell new Windows 8.1 Computer which are UEFI. I want to clone it to the other 24 Dell computers.
CASE 1 : 2 different partitions with 2 different Windows : --------------------------------------------------------------- If I install both Windows like above, when Sysprep Generalize Win7, it works fine. But if I SysPrep Generalize Windows 8.1, it's fine also, but never can boot again back to Win7. The start boot option is like this : Windows 7 Windows 8.1 If I choose to boot Windows 8.1, it's fine. If I choose to boot Windows 7, it ever boot to Windows 8.1. It means nomatter I choose to boot which Windows, it all goes to Windows 8.1 ?
CASE 2 : 1 partition for Win7 + Win81.VHD : --------------------------------------------------------------- I install Win7 (C and press Ctrl-Shift-F3 to form SysPrep. I create a Win81.VHD in Drive D: , imagex Windows 8.1 install.wim in it. Also press Ctrl-Shift-F3 to form SysPrep. Sysprep Generalize Win7 is OK , SysPrep Generalize Windows 8.1 is also OK. But after that I can only boot to Windows 7 fine, when choose to boot Windows 8.1 , it always restart and back to the boot menu ?
So I've searched, and I've tested, and now I'm about to turn my laptop into a frisbee and never buy a Samsung PC again. In short, I bought an ATIV 7 whose previous owner had downgraded to Win7. I wanted to put Win 8 on and I have a volume license as well as the OEM key so I burned the ISO (actually 2 different ones) using every method I could find (ImgBurn, Rufus, Iso2Disc, Win7 Download tool, etc.) It became clear that the USB needed to be formatted FAT32 with GPT filesystem, however in UEFI mode it shows the USB but won't allow me to select it - it just flashes. If I set it back to CSM and UEFI I can make a USB boot, but even if I use diskpart to clean the drive and convert to GPT it will fail to install because it detects I didn't boot in UEFI mode.
Here's the deal. When I'd installed it earlier this week in CSM and MBR mode, and then converted to UEFI it worked fine. So....I tested several recovery programs we use at work to make sure they'd restore it okay via bootable media. Paragon, Aomei, Macrium, Lazesoft - all boot media failed. ONLY True Image 2014 DOES ACTUALLY BOOT in UEFI mode on my laptop. The only thing I can figure is that the way WinPE 5 or 5.1 (whatever it uses) is set up on it agrees with my laptop. So how I can modify the Acronis recovery media or create similar WinPE media that might actually boot on my laptop.
I have a desktop PC Acer XC600, the hard disk is formatted in the UEFI-Scheme. Now I want to do a clean install of a fresh Windows 8, but I cannot manage to boot into UEFI-mode, neither from DVD or USB.
I can reach a boot menu by pressing F12, but there is nothing like shown in the article about installing Windows 8 in UEFI mode. Only standard bios devices show up. There are simply no UEFI devices. I tried different usb sticks, dvds, formatted them different ways, but the best I can get is the point where setup says "cannot install because the disk is formatted GPT".
But the acutal system is definitely running in UEFI mode (?)
Yesterday, after many, many problems with my computer, I finally decided to reinstall Windows 8.1 Pro onto my ASUS X200CA netbook. However, after backing up and reinstalling the OS, I found that when I tried to disable "Launch CSM" in my BIOS, all of my boot options would disappear and my laptop would continually boot into my BIOS. When I re-enabled "Launch CSM", the boot options would reappear - however, it had not included the "Option #1 - Windows Boot Manager" that I had seen in my other installation.
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?
I installed the 8.1 patch today and shortly after the mouse disappeared from my screen completely (I have a laptop with a touch pad). I tried going into task manager as just going in and cancelling used to solve this problem before installing the patch but this no longer works. I also tried rebooting (switching off then on again) but this didn't work and the computer didn't even reboot; just reopened my session exactly where I left off even when I waited ten minutes before switching the on switch again. I have temporarily solved this problem with a usb mouse borrowed from a family member but my family member needs it back (and I also would prefer to use the touchpad).
I should add here that I didn't want to do the installation when it started happening and while I meant to press the "default settings" option, I think I went with "customise settings" by accident. I just said ok to everything as I had a deadline and needed computer access. Could I have pressed "turn touch pad off" and if so how do I change this?
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?
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...
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 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.

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
So my computer is a Windows 8 Laptop, with UEFI on it..... I want to have Legacy instead of UEFI, and I was told on this site that I could do it, but I needed to reinstall Windows 8.....
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 ?
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?
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.
