No Legacy boot from CD-DVD - UEFI and Secure Boot are OFF

Q: No Legacy boot from CD-DVD - UEFI and Secure Boot are OFF


Just bought a Dell Optiplex 7010 Mini-Tower with Win 8 Pro 64-bit, 8 GB RAM, 500 GB hard drive and an Intel i5 3470 processor. Right now, it has Dell BIOS version A16.

It is normally in UEFI ON and Secure Boot ON, so that F12 on bootup (one-time boot options) does NOT normally show the CD-DVD as a boot option. OK - no problem.

However, if I reboot with F12 and select both UEFI OFF (meaning Legacy ON) and Secure Boot OFF and reboot, then F12 DOES show me the CD-DVD as a boot option, but if I actually try to boot up from a bootable CD, I get an error message.

I have practiced with two bootable CDs - a Knoppix and an Aomei Backupper, both made on earlier machines. Both these CDs work as boot-up CDs in my old XP machine, and the Aomei Backupper CD also worked in someone else's Win 7 Pro 64-bit machine.

What's wrong?

Again, please let me repeat that I am trying to boot from the CD-DVD AFTER I have turned OFF UEFI, turned ON Legacy and turned OFF Secure Boot.

Thanks.

Preferred Solution: No Legacy boot from CD-DVD - UEFI and Secure Boot are OFF

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

rdubayah,
If your computer was running WIndows 10 without any issues prior to downloading the Anniversary update, then you would not have had to change any settings in the bios to install the update.The UEFI and Secure Boot settings are to enable booting with a USB or DVD to install Windows.
Disable Legacy Boot Mode and Enable UEFI
Start the computer and TAP the F2 key to enter the bios. Once in the bios Press F9 to Restore the bios to the Default Settings. F10 to save changes and exit. You could have a hardware problem. To run a hardare diagnostics on the computer you would start the computer and TAP the F5 key. Insert a cd/dvd in the optical drive for running the diags.

Hello Lenovo Forum!This is driving me mad. I bought a SATA-to-USB3 Adapter to connect my SSD and HDD from my old computer and boot from them (I want to use the Linux on it). Yet I can't figure out how to do that. Secure Boot is off, Legacy Boot is on and yet - everytime I choose the drive in the boot menu, the screen goes black, there is a short drive access, and then I'm back at the boot device menu. I don't really know what to try now. Reimaging like most other threads here suggest doesn't help in that case because it's not a simple installation medium. What I tried aswell: Attaching the Adapter via a USB2-hub to check if there might be an issue with USB3 support. When plugged into my friends X230, both drives boot up perfectly fine and he can use them just fine. Any kind of help is highly appreciated.Kind regards,Iriya EDIT: Here the BIOS Options which I think are somewhat useful:Config TabUSB UEFI BIOS Support - Enabled (Tried turning it off, didn't helpSecurity TabSecure Boot: DisabledPlatform Mode: User ModeSecure Boot Mode: Standard ModeStartup TabUEFI/Legacy Boot: BothUEFI/Legacy Boot Priority: Legacy FirstBoot Mode: QuickRestart TabOS Optimized Defaults: Disabled

Hello, first post here...

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:

I've searched a lot, looking for solutions and 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).

Hi all,

Currently having a wake on lan issue with a certain computer.

The machine is setup correctly but the windows boot information is stored in a 100mb UEFI partition, and when the computer wakes on lan, it will not boot windows, just sit at a blank screen.

When it wakes on lan it is trying to boot from the legacy device (same blank screen happens if you choose to boot from it from bios)

ive tried updating the bios but no luck, all settings seem to be as they should be.

Is there some trick to get it to load the UEFI MBR, or is there a safe way other then reformatting the machine to move the MBR over to the legacy device itself?


Thanks for any help.

A:Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

I had to buy a new (SSD) HD and had trouble booting from a disc until I enabled Legacy Mode and disabled Secure Boot in BIOS. Boot orders in both UEFI and Legacy are the same, with DVD Rom set to boot first. Also, the settings for IPV4 and IPV6 are set to IPV4 (Legacy) when they were once set to BOTH IPV4 AND 6 and are unable to be changed, if that's important. Now whenever I boot up I always get a "No Boot Device Found" message until I hit "Enter" at which point i'm allowed entry into my precious Win10 laptop.  I disabled Legacy in BIOS, but then i get a different "No Boot Device Found" error, and hitting "Enter" doesn't help. Could some kind person tell me how to correct this, and possibly why it happened and the differences in each option? I'll settle for how to correct this, though, with much gratitude.  MUCH gratitude. GN

OS: Windows 8.1 with Bing 32 bit

Hello all,

This is my problem:

I can't get my USB drive to load while in Secure Boot mode and continue running into 'Boot Device Not Found. Please install an operating system on your hard disk' screen. The only method that works thus far is disabling Secure Boot mode and enabling Legacy
Support. Here are the methods I have tried based on extensive research of various forums after several days:

- Performed all the generic System Diagnostic tests (F2) + Memtest86 + sfc /scannow multiple times after every fresh install + physically checked HDD. Performed all HP recommendations: http://support.hp(DOT)com/us-en/document/c01443463


- Did multiple fresh installs of Windows 8.1 with Bing (32 bit) erasing all partitions from hard drive every time (my system is designed for 64 but I only have access to a 32 ISO). Installed using Legacy Support (I understand you can't go back and enable Secure
Boot and disable Legacy once it has been installed this way but due to lack of any other way of installing Windows, I have no choice).

- Used 'Windows 7 USB/DVD Download Tool' to create ISO which automatically formats drive to NTFS; converted to FAT32 using 'AOEMI Partition Assistant' software (preserving all partitions/data) but it still won't read.

- Used 'Rufus v. 2.11.995' software to create ISO as FAT32 under several different setting iterations:

Hello all, This is my problem: My BIOS won't boot my USB drive while in Secure Boot mode (Legacy Support disabled). After researching this, I realized UEFI Secure Boot won't read NTFS formatted flash drives hence requiring user to reformat to FAT32. I've reformatted to FAT32 but it still won't boot. I continue to run into the 'Boot Device Not Found. Please install an operating system on your hard disk.' screen. The only way to get the USB drive to boot is to disable Secure Boot and enable Legacy Support. Virtually every forum I have researched pointed to this being the problem (aside from loose hard drives / hard drive and/or memory problems). I have checked the hard drive and have ran the F2 System Diagnostics and am sure there is no problem with the HDD. I have even tested the RAM/CPU with Memtest86 with 0 errors. I have ran multiple 'sfc /scannow' tests after each fresh Windows install and there are no corrupt files during installation. I have been trying to install a fresh Windows 8.1 with Bing (32 bit) on a system that originally came with 64 (there were no 64 bit ISOs available anywhere to download and since Microsoft conveniently doesn't make this specific Windows version available for download via their Media Creation Tool (or anywhere else on their or their affiliate sites for that matter), I was forced to resort to a 3rd party site to obtain this download. The problem is I am forced to install using Legacy Support as there appears to be no o...

Hi, My comany is purchasing HP EliteDesk 800 G2, some comes with HDD and some with SSD.We deploy Windows 7 x64 using SCCM using legacy boot. On a machine with HDD installed I can configure the boot options to use legacy boot, but when I replace the disk to a SSD drive the only boot option for this drive is UEFI.That causes the deployment to fail because the drive need to be partitioned as GPT.On the other hand, if I disable legacy boot, PXE boot to UEFI and partition the disk as GPT, after the image deployment the disk is unable to boot with 0xc000000d error (I imagine the cause is Windows 7 support becuase it does work on Windows 8.1). Bottom line, I can install Windows 7 on a HP EliteDesk 800 G2 only if legacy boot is enabled and I partition the disk as UEFI.Is there any way of forcing the SSD to boot as legacy and not UEFI?Is this issue caused by the workstation or is it enforced by the SSD? thanks.

If your PC or laptop supports UEFI and legacy mode then the following tips may help you. Legacy enabled:If the bios setting is legacy enabled then hard drives and USB devices will normally boot.  If you are using two independent hard drives that are not connected by boot manager then the UEFI boot hard drive will always boot first before the legacy hard drive unless the bios allows you to change the boot priority. Legacy disabled (UEFI mode):If the bios setting is legacy disabled then only UEFI devices will boot.  You may run into no hard drive selection menu, no boot option menu or Boot Device not Found followed by a message Hard Disk (3f0). USB flash drives boot considerations:If you wish to boot up a USB flash device using Windows 7 repair, Windows 8 repair, Windows 7 or Windows 8 installation media then be sure to create the flash drive formatted as FAT32.  You may notice a bootable flash drive showing twice in the boot menu, one marked UEFI and one not marked UEFI.  Both will boot up. The popular MS Windows 7 USB WIndows installation media creation tool will create a NTFS flash drive using a Windows 7/8 iso file in NTFS format which is not bootable in UEFI mode.

I am in the process of doing a number of clean installs. I am trying to make a decision as to whether or not to utilize the UEFI and Secure Boot modes which are available on the MBs.

It seems from an initial attempt, that I cannot simply use UEFI/GPT without turning on Secure Boot...that is one must NOT use CSM (turn it off) and USE Secure Boot. You cannot use UEFI without Secure Boot.

Is this correct? I am considering us9ng UEFI without Secure Boot because I hear it is faster.

However, I am concerned that I will run into all sorts of trouble turning Secure Boot on with respect to double booting Win 10...and additionally with creating images with Acronis.

I have been in the habit of creating a new PC with an extra drive with a cloned OS...then disconnecting the drive so that if the first OS drive fails, the person can boot up quickly with the other drive. I am concerned that there will be a problem with Secure Boot.

I mean, how many times have I been infected with a root kit.....some virus that take over at boot time...Answer...never since I started with PCs in 1991!

So, anyone really think Secure Boot is worth it?

Microsoft designed Secure Boot to protect the computer from low-level exploits and rootkits and bootloaders. A security process shared between the operating system and Unified Extensible Firmware Interface (UEFI, replacing the BIOS), Secure Boot requires all the applications that are running during the booting process to be pre-signed with valid digital certificates.

When you reinstall there are some critical partitions.  You cannot leave any of those of the drive and reinstall Windows 10.  Data partitions should be OK.
To boot a USB drive as UEFI, assuming your system has that capability, you have to format the USB drive as FAT 32.  It must use an x64 bit version of Win 10.
When you boot you should be able to see a Boot Device Menu.  Look for something that shows as UEFI and boot to that.  If you don't see a UEFI option, the Bios may be set incorrectly or the USB drive is not configured correctly.

Security Tab:
Secure Boot = Disabled
 
Exit Tab:
OS Optimized Defaults = Other OS / Disabled
 
2. When done, press Fn+F10 to save and exti and observe.

Hi, Shutdown the notebook. Tap away at the esc key as soon as you press the power button to enter the Start-up Menu and then select the Bios Menu ( f10 ). Under the System Configuration tab, expand the Boot Options Menu. Here you should find the option to set Secure Boot to Disabled and Legacy Devices to Enabled. When done, press f10 and select to save the changes. You may then have to enter a 4 digit pin displayed on the screen to confirm the setting changes ( note that you will not see a display of the numbers as you enter tham ) - enter the code and hit enter. Regards, DP-K

I am trying to install Windows 7 from a DVD to an HP 19-2113w All-in-One with Windows 8.1 as the factory install. I have entered the BIOS, turned off Secure Boot, restarted, and entered the code to confirm that I want to disable Secure Boot. Upon restarting and going back into the BIOS, Secure Boot shows it is "Disabled." HOWEVER -- when I then go into the boot options and try to enable the legacy boot devices, it gives me a message saying "You must disable Secure Boot before you may configure this option." As I previously stated -- Secure Boot shows "Disabled" when I check under the security tab.  How much more disabled can it get?  Am I missing something here?  Is there any other way to install Windows 7 from a DVD onto this computer?

We are pushing a new image this summer but we need to make boot and file system changes, my boss wants me to automate this process. the goals are to desable legacy in bios, enable UEFI, select PXE,  change UeFI boot order (usb,cd, NIC, Hd) using the Bios configuration tool at command line. I have the config.ini file from the bios. can I make all those changes at once or do I have to reboot in between enable UEFI and changeing the boot order The why: we are moving from MBR to GPT with the new image Win10, and we save time on the boot by disabling legacy. The boss says so. (the short answer) any tips or suggestions welcome.

Hi, I have a bios version 7 on me pc and I dont have a update for a bios 8.I really need to disable secure boot and enable legacy mode but I dont have that option.Is there a way or a trick that I can do this?

A:Disable Secure Boot and enable legacy mode

@Siemen,Did you system originally have WIN 7, as listed here?   If so, the BIOS is correct at rev 7.  You can not  use the newer UEFI graphic cards because there is NO update BIOS available.  Your correct, you do not have a way to disable secure boot and enable legacy. In another post you asked, and got no answer.Yes, the GTX 660 will work, with an adequate new PSU.  Recommend EVGA GTX 600 and Corsair CX600 PSU.  On the GTX 750Ti inquiry, only chance would be the Hybrid vBIOS cards.  PSW<> The GTX 670's are a tad touchy.

Hello, 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. Does anybody know why this would occur or how to fix it? I'm sure there's likely something I missed. This is rather urgent, so any help would be appreciated.

Hi there

At the reboot have you removed the installation media -- it might be re-booting again from the install media.

I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below  these options there is a little note with an asterisk saying "Unselectable for Secure Boot"). How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.   Thank you very much for helping me out!

I'm not sure where it is in your BIOS (security tab maybe) but there should be an option to turn off secure boot.

I am looking for a Lenovo (no other will do) laptop that could be an alternate to the W530 (about 6 years old). My key requirements are (native, not via a VM) support for Windows 7 64-bit (I do not intend to use Windows 8 or 10, so need either factory installed, recovery discs available, or at least drivers available from Lenovo for Windows 7 Pro 64-bit), support for over 16GB RAM (example, 24 or 32 GB), support for legacy BIOS boot mode (I do not intend to use UEFI), and supports at least 1920x1080 screen resolution. Weight, size, and (to an extent) cost are uncritical. Some versions of W530 fits this description; I am searching for alternatives prior to committing to (another) W530. Thank you for any recommendations.

Hey all I have a Touchsmart 15-d087ca. I was going through the steps to fix my phone (which is currently stuck in fastboot mode), and one of them was to disable secure boot. So I selected the disable secure boot option, but didn't enable legacy boot, which may have been an incredibly stupid thing to do. I'm not sure if this is the cause of the problem, but it seems likely. I have to admit I'm not an expert when it comes to computers. Upon pressing f10 to save changes and restart, the computer turned off, and then turned back on. But now the screen is black - the backlight is on and the machine is running, but there's nothing I can do to get away from the black screen. Obviously this kinda sucks, because now my phone and laptop are both stuck somewhere in the boot process. Am I screwed, or is there a way to fix this issue? EDIT: I have tried a hard reset, the emergency BIOS access thing where I hold windows + B + Power On, and will try taking the memory out and putting it pack in tomorrow. I'm using this instructional video to guide me

Is there som trick to get HP computers with UEFI BIOS to boot from PXE w/o turning off secure boot? My environment is Windows 2012 server with SCCM. The WDS service is running, I can PXE boot other brands of laptops (dell, microsoft), so I know my setup is somewhat with in the ballpark. I can also boot the HP UEFI computers with a USB stick w/o turning off secure boot, but once the bootimage is on PXE, it fails. I do not use DHCP options, nor IP helpers. The clients are on the same subnet as my DHCP server and my DP/WDS server. We have both UEFI and BIOS computers in our environment. All manage to PXE boot except the HP UEFI computers. Unless I turn Secure Boot off - then it happily loads the image. Is there perhaps some secure keys the computers are missing? Thank you in advance for any answer to this. We have ~3000 computers that are affected.

A:PXE, UEFI and Secure Boot

Hello I have a very similar issue. UEFI and Secure Boot are enabled, MS SCCM 2012 R2, etc. Want to deploy Windows 10.... In my case several laptops models (HP Elitebook 820 G2; HP Elitebook 850 G2; HP EliteBook Folio 9470m; HP Zbook 17 G2) don't want to boot in WinPE. After Downloading WinPE into RAM and a restart a HP message appears: "No bootable image found, notebook will shutdown" But WinPE was successfully downloaded into OS Boot Manager. I've checked it with Bcdedit. Interessting point is that if I login to the BIOS now and change the Secure Boot to "disable" the computer boot in WinPE immediately. Other Models like HP EliteBook Folio 1040 G1; HP ProBook 650 G1 works fine with enbaled UEFI and Secure Boot !!! All Laptops have latest BIOS version. I've tried BIOS Factory defaults and Security defaults. Nothing changed if UEFI and Secure Boot is enabled. It seems there are different SecureBoot checks implemented at HP. Has anyone a solution, similar experiences or an explanation ?? Thanks a lot in advance

Hello,

I am in charge of updating several of our Windows 7 machines in our environment to Windows 10, we have a security requirement for our network that all machines running Win10 must use UEFI, SecureBoot and Credential Guard.

I'm trying to determine if some of my older machines running Windows 7 are UEFI capable, I have a mix of HP, Dell machines. My server is 2008R2.

After googling it seems some hardware won't support, but I haven't found an easy way to determine which machines will or won't.

I recently learned about UEFI boot and Secure boot when I was downgrading my aunt's Windows 8 laptop to Windows 7, but I like windows 8 and I have it on my ASUS N76VZ laptop (which came with windows 7, so it isn't using or doesn't have UEFI boot or secure boot), and I'm wondering if there is a way for me to set up UEFI and Secure boot on my laptop.

First, there doesn't seem to be an option to set up UEFI boot or Secure boot on this laptop, and I do have the latest bios, but here are some pictures of my BIOS screen and options (if you see the UEFI option there, point it out!):

Main
Advanced
Boot
Security
Save & Exit

Also I was thinking of setting up secure boot but there doesn't seem to be an option for that either?
Any help would be greatly appreciated!

Thanks,

-Derek

A:Set up UEFI/Secure Boot on laptop?

Enable UEFI on ASUS N76VZ laptop

You will need to

1) ENABLE CSM Lanuch

2) Set to UEFI or UEFI & Legacy mode.
