Windows 8 UEFI Install - File More Than 4 GB?
Jul 7, 2013
So, I am trying to install Windows 8 with UEFI support.
Which means file system can only be fat32 because UEFI doesnt support NTFS. Now my install.wim file is over 4GB in size, so I am unable to copy it to the usb drive because of fat32 limitations.
How would you go about this ?
I tried creating 2 partitions on my usb. One fat32 - which contains all boot data and second partition is NTFS which has only my install.wim file.
Now I am able to boot, but it doesnt detect my install.wim obviously because it is in another partition. What command should I use to pull it from another directory ? I am able to open CMD on the set up screen.
OR any other way to accomplish this ? How would you go about this ?

I would like to know how to install Windows 8 from a hard drive partition, so that is much faster than installing from a USB ... I've seen guides on how to do, how bad MBR, and I want to know how install W8 from a partition GPT / UEFI.

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 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 cannot install windows 8 in BIOS or UEFI mode.
it's getting boot and install only in EFI mode. after trying to reinstall it won't allow me to select the disk partition, as it gave me the error "
Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks." i tried all the given solutions on GOogle. even i cannot recover or refresh using windows 8 environment. many times it gives me BSOD. cannot vonvert to MBR as it says it cannot be done on virtual HDD.
tried many things nothing works, need to install windows 8 after every 1 or 2weeks, many a times my BCD data gets corrupt, and windows wont start. Also tried many things to repair this, but only thing that works is reinstalling windows 8.
That gpt or MBR error was solved by selecting UEFI:CD drive. in boot options by pressing F12 after inserting the disk.
My system configuration:

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".

Why I had to enable UEFI in my bios to be able to install Windows 8.1 with update in my pc?
D510Mo using na hdd from acer notebook. Removed the partition using diskpart, cleaned it... no joy!
Windows setup says it couldn't install in that disk and I had to check the install logs (where the hell those logs are saved?)
There where no GPT partition on disc, no nothing...

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 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 nuke system for clean install. I understand there will be system reserved partitions, however, my main concern relates to OS and DATA partitions - Review attached screenshots :
150 GB for C (OS) drive?
30 GB for RECOVERY?
Remaining for DATA?
I am unsure where did I read RECOVERY should be the last partition - how would this be accomplished?

I recently called Dell support about my Inspiron 15R SE not booting and they determined my hard drive had crashed. They shipped a new hard drive to me and got me to install it but I had problems installing windows 8 as it was factory installed using UEFI.
Windows 8 setup would start but immediately gave an error about missing a media driver. The driver and utility discs I was provided did not seem to work at all. I called Dell support again but the guy I was talking to just told me that UEFI was confusing and told me to go into bios and change to legacy boot, which worked and I am now running windows 8 in legacy boot mode.
But is there a way I can reinstall in UEFI? From my brief research, it seems to be more efficient... Is there a driver I am missing that wouldn't be on the windows or driver and utilitys discs?
Doesn't seem like phone support people know much about UEFI ...

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.

The problem is that I can't install the .NET Framework 3.5 on my Windows 8.1 because when i try to install it, appears:
"Can't install the following feature: .NET Framework 3.5
Can't find the specified file. Error: 0x80070002"
The same if i download the dotNetFx35setup.exe setup from Microsoft Website. I tried also in other 2 ways suggested here (Installazione di .NET Framework 3.5 in Windows 8) :
- In Control Panel -> Programs -> Enable or disable Windows Features -> .NET Framework 3.5 but i receive the same error
- I insert Windows 8 DVD in the D: Unit and i type in the prompt command this code:
Code: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:sourcessxs
But I receive this error:
"Features Activation: 99.8%. Error: 2. Can't find the specified file"

I bought a Toshiba laptop that came with pre-installed Windows 8. I went into the "Bios" and switched from UEFI to CSM, Now my laptop just doesn't work. I am on a public computer posting this because mine will just not boot at all. It won't even show the boot logo, and I cannot get back into the Bios to switch it back to UEFI. I am not sure what information I could add on to here to be more clear other than I screwed up bad. The laptop didn't come with a disk, and I tried to hold 0 while powering up the laptop hoping that it would reset to factory settings, but no luck there either.

I have very little experience with Windows 8 until now. I am having an issue trying to run System Refresh or System Restore from the System Recovery Environment booted from the Windows disc. When I try to run it from the disc I already System Refresh says that the drive is locked. I tried System Restore and it said no OS's were found. I went into the CMD prompt and went to c: and can see the drive just fine.
Steps tried: running fixboot, fixmbr, rebuildbcd commands from CMDrunning dskchk /f (which forced a dismount)
I then read something about a non UEFI bootable disk couldn't access a GPT partition, which I think is the case here. So then I tried oscdimg to make my iso UEFI bootable (twice) and the UEFI Boot Manager still only shows 'Windows Boot Manager' at the boot menu. I even tried downloading an iso that was already UEFI incase I did it wrong and it still doesn't see it.

I don't know how I did it but I got both Windows 7 File Recovery and Windows 8 File History active at the same time. I upgraded from Win 7 to 8 Pro and transferred settings so win 7 file recovery was already active, when I tried to turn on win 8 file recovery I got a message saying I cant because win 7 FR was active. So I deactivated win 7 FR then activated win 8 FR, for giggles I went back and turned on win 7 FR and it worked. Now I have both active, from what I have read this was not possible. Did I break my OS or am I just lucky?

I am using Windows 8.1, now I have a problem because i wanted do dual boot it with ubuntu and it didnt work on UEFI mode, but then when I installed ubuntu windows 8 wouldn't start... then I formated it with a downloaded windows 8 torrent... but now I can't start it on UEFI mode
It says something "media not found" or "failed" ... so if I want to start it I have to change to legacy mode......
Is there anyway to get it back to start it with UEFI? It ain't activated yet.. Windows 8.1 pro... is there any activatior or something too???
Or if I downgrade it to Windows 7? would it be any more the UEFI problem?

In Windows 8.0 File History, it had the nasty habit of duplicating your library files on your backup ( in my case, my external USB backup drive ( Replica 2 Terabyte ). By DUPLICATING, I mean they get copied over and over and over again... This happens to ALL of them, even though you have not touched the majority of them for YEARS. (File History is suppose to copy them over the FIRST time, then copy a new copy with a new name (old name plus date) if you edit the file in any way). I turned of file indexing on ALL my drives, except my C: drive, to see if that would stop it ( this is recommended in many threads on other sites ).

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 got a (at the time new) MSi laptop several months back with just a regular Windows 8 Core x64 on it and a UEFI boot system (or whatever is the name for "BIOSs"). At some point I had problems with the settings - I couldn't open any of my computer's settings - and I researched long and hard to no avail.
So I installed Windows 7 32-bit (the only disk I had). Now, I'm trying to upgrade to Windows 8.1 Pro. I noticed that after the installation of 8.1 Pro my system was still running in 32-bit, so I made a bootable USB stick with the retail version of Windows 8 Core with no key just to get the system back to x64. It worked just fine. I cannot, however, boot in UEFI mode. I believe the partition got wiped somewhere in the Windows 7 installation.
Whenever I enter UEFI by pressing the DEL button (I cannot see the UEFI firmware settings tile under the Troubleshoot option) I see the boot mode is LEGACY and when I change it to UEFI, save and reset, it doesn't boot, giving me a "No media found" error. I don't care about my settings/files as long as I get UEFI back with Windows 8.1 Pro running. My next attempt would be to try and install 8.1 Pro from USB stick, wipe all the partitions and hope the installer will create new ones. The reason this would work when it didn't before is because I had the OS running in x86 not x64 (which UEFI doesn't support). So maybe now that the system is back to x64 the Windows installation will restore the UEFI back to its original state.

Windows 8.1: HP Pavilion 2475ea Desktop PC.
I have Secure Boot turned off. I have Legacy Boot turned on, but do not think that is needed.
This link gives me instructions to boot from CD but they seem not to make sense from No 2... [URL] .....
In that at 5-6-7 it seems to require me to select the CD then boot to Windows from HDD then restart and do the same again, but this time select CD again, or something??
I expected to set the device, then restart the computer and it would boot from the device, not restart Windows as described. I was able to boot from a WinPE 4b CD.
I then decided to try changing boot order in the UEFI BIOS. From then on the HP (F9) described menu showed 'Windows Boot Menu' only under UEFI Devices. I could only boot from CD after putting the order back to 'Windows Boot menu' at the top of the order list; after which, as long as the CD was in the drive the (F9) list showed the CD drive as selectable to boot from.

Windows 8. I am confused with the Legacy and the UEFI boot methods. The reason I am confused I think, is because I read to darn much on the Internet. One bit of confusion is with respect to changing from UEFI to Legacy. It would appear from some comments that if I do that, Windows 8 won't boot anymore. I would have to change back to UEFI for indows 8 to boot.
I also read that changing back to UEFI could be a major problem when trying to access the BIOS. No, I am confused. My ultimate goal is to set my laptop up to dual boot Windows 8 and Ubuntu. Like I have been doing for the last multiple years with XP and Windows 7.

what settings are required in the UEFI Bios to run recovery USB/ disks or Linux live CDs. It all used to be so simple. The manufacturer seems unaware that it supplies UEFI systems - so I am working blind. Have tried boot CDs and USBs but all have booted straight into Windows to date. I don't wish to change settings I have no understanding of.
I have a Medion /Lenovo desktop with an AMI UEFI Bios (12 July 2012) and Aptio Setup.
The following seem relevant are supplied as enabled in "Bios":
Intel Rapid Startup Technology
Quiet Boot
Boot Select Mode [UEFI]
UEFI Hard Disk BBS Priorities - Boot Option #1 - Windows Boot Manager
Secure Boot - Secure Boot Mode [Standard]
What do these all mean and what effect do they have on how Windows 8 runs and how boot drives run?

My wife got a new Dell XPS laptop from her employer. A very impressive bit of kit with Windows 8, 64 bit, masses of RAM and many, many processor cores (dreadful touchpad though ). And 1TB HDD.
She asked me to set up it the same way as her existing Windows 7 laptop, so a fun few hours discovering how the charms bar works (before giving up on that and going for Start8) and installing various bits. I then decided to partition the huge drive so the OS and program files are on one partition which can be imaged and restored with Acronis as required while all the jpgs mp3s docxs etc remain safe on the second partition (every computer in out home is set up this way and I've found it to be the best method).
I shrank the partition as much as possible and ended up with 400 GB before immovable files put a stop to that - needlessly large I thought so I installed EASEUS partition manager which I have used with W7 without problem (can you see my obvious mistake yet?) and set it for a 200 GB partition, started it going and popped back five minutes later expecting to find everything as desired. Instead the laptop no longer believed it had a HDD. The current situation is that the machine is pretty much as wanted except the partition sizes aren't as required and no Acronis image has been made.
So, the questions this experience raises are:
1. Did the drive fail or did EASEUS break it? (If it was just waiting to fail my opinion is that it's good to find out so early on and not when it was full of data that hadn't been backed up).
2. Which partition managers are safe to use with the combination of Windows 8 and UEFI that Dell have produced? I'm somewhat nervous of just experimenting on this point.
3. Is Acronis safe to use with Windows 8 and UEFI.
