Setup Installation :: UEFI USB Disk - Does Not Boot From Windows 8

Mar 13, 2013

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.

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?

Setup Installation :: Windows Boot Manager - Deleted UEFI Boot Option?

Mar 24, 2014

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.

Setup Installation :: (Recovery) Partition In GPT Disk For UEFI Installation?

Jan 28, 2013

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?

Setup Installation :: Recover Legacy Boot And Remove Old Entries From UEFI Boot

Aug 21, 2013

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.

Setup Installation :: Unable To Find Windows Boot Manager In UEFI BIOS?

Jul 24, 2014

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.

Setup Installation :: Dual Boot Win7 And 8.1 - SysPrep With UEFI GPT

Jun 27, 2014

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 ?

Setup Installation :: Samsung Won't Boot Install USB In UEFI Mode?

Apr 2, 2014

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.

Setup Installation :: Acer XC600 - No UEFI Device In Boot Menu

Jul 21, 2013

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 (?)

Setup Installation :: Installing Windows 8 On A New Disk Boot

Aug 14, 2014

Before, my PC was setup like this:

- disk0: windows xp
- disk1: windows 7
Bios boot priority set to disk1.

So no boot loaders, when I (rarely) need xp, I would switch via bios

Now I wanted to try Windows 8, so I've

- download 'Windows 8.1 Enterprise Evaluation' and burnt on a dvd

- bought and connected a new disk (disk2)

- boot from dvd, installed choosing the new disk2

Now, everything works fine, Windows 8 got installed on disk2. But the strange thing is this:

- if, from bios, I choose disk2, it says the disk is not bootable

- choosing disk1, a boot loader shows up, letting me choose between win7 and Windows 8.1

(- choosing disk0, nothing has changed, xp starts like before)

So, I'm confused. I was expecting Windows 8 booting from the new disk2.

- why disk2 doesn't boot?

- would have been better physically disconnecting disk0 and disk1 before installing?

I just received an Asus Zenbook with 8 preinstalled.

It was configured with static IP and my office configuration, I would like to split the existing partition, create a new primary partition and clone the Win 8 installation in the new one.

Then set up a dual boot configuration, so I can have a clean "office config" and an "home config" with the same licenses and software in which I can mess with the configuration and setup my home stuff (DLNA server, access to home headless server, software to flash android handset, etc).

Setup Installation :: EFI System Partition Missing Files - Repair Disk Won't Boot?

Nov 30, 2013

While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.

I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.

I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.

I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in EFIootootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.

Where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Any Windows Repair iso that works.

Setup Installation :: Installing Windows 8.1 As Non-UEFI

Nov 18, 2013

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?

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?

Setup Installation :: Can't Install Windows 8.1 On Non-UEFI Laptop

Jun 30, 2013

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.

Setup Installation :: Windows 8 Install Using UEFI Still Doesn't See 4TB

Jul 27, 2013

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 just bought a copy of Acronis True Image 2013 with Plus Pack. It appears that this is all I need as True Image will install the new motherboard drivers as part of the migration process. But do I stay with MBR or move to GPT?

Presently both Win7 (on a 120GB SSD drive) and Windows 8 (on a different 120GB SSD drive) are both MBR format. I don't want to start over from scratch. That's why I bought the Acronis 2013 with Plus Pack.
