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.....
View 1 RepliesRight 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.

And if so, will it perform slower? Or only boot time will be affected? Any other disadvantage of doing so?
View 9 Replies View RelatedSo 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..
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 graphics card, Nvidia GT650 is not ready for UEFI installation and I have no way to flash the bios. If I boot using legacy bios, install the card, then can I flash the card BIOS and then return to UEFI booting?
The card is currently not installed and I have no other system to use to flash the cards bios.
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.

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.
View 2 Replies View RelatedI 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.
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?

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.
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 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 Dell Inspiron 7720. I have created an uefi bootable usn flash disk with rufus 1.4b
I'm trying to boot from it so i can create a Windows 8.1 uefi installation and the problem is that the usb flash disk wont boot.
I have secure boot enabled and legacy option rom disabled.
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 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
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?
Windows 8 clean install crashes on first screen
Side note - I succeeded on installing Windows 8 on that particular laptop using UEFI, but NOT legacy. No matter what I tried it failed.
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.
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
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".
View 1 Replies View RelatedI 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.
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...
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.
View 2 Replies View Relatedusing 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 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?
accidentally i delete my efi partition. now i cannot boot up to windows 8
