Setup Installation :: Can Windows 8.1 Be Installed As Legacy MBR? (Non-UEFI)

Nov 19, 2013

And if so, will it perform slower? Or only boot time will be affected? Any other disadvantage of doing so?

Setup Installation :: Switching From Legacy BIOS To UEFI

Jan 29, 2014

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.

Setup Installation :: How To Reinstall Windows 8 On UEFI From Windows 8 Legacy

Mar 1, 2013

So I fresh installed Windows 8 on Legacy boot, deleting all partitions even the factory restore partitions, everything. I realized late that the new trendy thing is to install on UEFI, however I'm having difficulty doing this. How exactly do I go about this?

My laptop has a 256 gb SSD mSATA where Windows and apps are installed, and a media HDD sized at 750 gb. I deleted every partition I had when I installed Windows 8 and made new ones for a fresh install, however I think this is preventing me from doing a UEFI install correctly..

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 :: Just Installed Windows 8 With UEFI But 2nd Drive Stops

Aug 10, 2014

I installed Windows 8 with UEFI on a GPT SSD like the tutorial on this very forum states, but I ran into an issue when I plugged in my secondary HDD (1tb MBR?). It won't boot even if I make sure Windows Boot Manager is the primary boot option. What can I do about this?

If I unplug the drive, it boots fine. If I plug it back in, it stops and Windows tries to repair itself.

Apparently if you're using Win 8 with UEFI, you can't have a 2nd drive that uses extended or logical partition. Since I had Ubuntu on the 2nd drive (logical) it wouldn't boot. I haven't done it yet, but If I delete the partition it should work just fine. I created a bootable usb with Gparted and will fix it later.

Windows 8 - Legacy And UEFI Boot Methods

Jul 14, 2013

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.

Dell Inspiron 5721
Windows 8
Intel i7 @ 1.9 GHz
BIOS Version - Dell Inc. A06 2/22/2013
SMBIOS - 2.7
Secure Boot State - On

Setup Installation :: Cannot Downgrade To 7 Legacy Enabled Secure Boot Disabled

I am having an issue with downgrading to Windows 7 and It's not nearly as easy as normally installing an OS. I get to the expanding files screen, and once the system reboots it goes back to the Windows 7 install screen. This is an issue, because it should continue with the installation.

Setup Installation :: Boot Menu Alternates Between Modern GUI And Legacy Modes

Nov 3, 2013

I have an older Dell laptop with no secure boot that has Windows 8.1. I shrank the partition and installed Linux for a dual boot setup. Normally I install the GRUB2 to the root of the Linux partition so I don't "see" the Linux installation at all until I use easybcd to create a boot menu item. Easybcd wipes out the pretty blue GUI boot screen and you end up with the black and white "legacy" menu. This was all expected.

Now the weird part. Sometimes when I boot the computer I get the black and white boot screen and sometimes I get the modern GUI boot screen. I prefer the black and white boot screen because the modern boot screen does a second reboot when you select a linux installation.

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?

Setup Installation :: Installing Windows 8 Without UEFI

Aug 20, 2013

I have an Acer Aspire 5745G-644G50MNKS notebook with preinstalled OEM win 7 home premium.

Specs as following:

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 :: (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 :: 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 :: 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

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 :: Installing Windows 8 On UEFI To RevoDrive X2

Dec 4, 2012

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.

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?

Setup Installation :: Windows 8.1 Partially Installed On SSD?

Feb 25, 2014

I was trying to install windows 8.1 on my new SSD for my laptop. However during the installation process, I accidentally unplugged the USB drive that had the Windows 8.1 install on it and the process was interrupted.

Now whenever I plug in that SSD into my laptop it gets stuck in this "boot loop" kind of deal where I hear it start up and turn off all in a matter of 10 seconds or so and all I get is a black screen.

Without the second hard drive my laptop runs almost flawlessly. Only issue is upon booting up it asks which operating system to use and gives me two options: Boot from Windows 8.1 or Boot from Windows 8.1 volume 4.

Setup Installation :: Windows 8 Installed On Only One Partition?

Earlier today, I decided to do a fresh install from my retail CD of Windows 8. Windows 8 was my existing OS. (I just wanted to start fresh). For some reason, it did not create the usual two additional small partitions (system reserved and one called recovery). Everything seemed to work alright, but was wondering why this happened (only the C: partition was created).

Setup Installation :: Migrating Windows 7 And 8 From BIOS To UEFI Computer

Jun 13, 2013

Question: How would you approach this migration?

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.

Setup Installation :: Installing Windows 8 / 8.1 On External HDD UEFI Bios Only

I'm trying to install windows 8.1 to an external hard disk (solid state drive 128 gb usb3).

I've tried easyUFEY WinToUS creator and AOMEI Partition Assistant Standard(Windows to go) with no luck.

My bios has UEFI option only(no legacy). On my old laptop it works just fine(I had the legacy option) but now, I cannot do that anymore.

I'm pretty sure it's a bios boot issue and I don't know how to fix it. I've tried using GPT partition instead MBR, Still nothing.

The laptop is a sony vaio duo 13 and I have no legacy option in bios
