Bios Will Not Let Me Enable Legacy Boot Even When Secure Boo...

Question: Bios Will Not Let Me Enable Legacy Boot Even When Secure Boo...

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?

Answer:How to disabled secure boot and enable legacy

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

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?

Answer: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.

Answer:BIOS Refuses to Enable Legacy Boot

Thank you for the reply.  I ended up doing the following, which worked finally(not sure why):- Updated BIOS back to V 02.05- reset back to factory settings in the main menu- back into bios, set password and ownership tag as needed by the school district i work for--->reboot- back into bios disabled bootable devices usb and cd rom (as is school district tech policy)- went to secure boot options and selected in the drop down "enable legacy and disable UEFI boot" -->reboot- back to bios THIS TIME the check box next to legacy in the boot options menu was available.  I checked the box and was also able to uncheck UEFI boot -->reboot- f12 to PXE boot and like magic it finally worked Again, this is very similar to the process I tried in the begining the only difference was the amount of reboots it took to get it accomplished.  I did have a similar issue with another 800 G2 and no matter what I did it would not PXE boot so I rolled the bios version back to 02.04, restored factory settings and did the process I just oultined above.  AND IT WORKED on that machine.  It is an inconsistant issue we are having with the 50 or so 800 G2s our district purchased this last month.   In any case we are able to get these machines to PXE boot using one of the two methods I just mentioned.  So we're good for now.  Thanks again for your reply.

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

Hi there guys - any help will be much appreciated

I had a bit of a problem with Malware which led me to reinstall windows 8. I had also at the time been trying to install Linux to dual boot beside it. However, upon reinstalling I got the annoying watermark saying "Secureboot isn't configured correctly."
Having decided I would rather remove the watermark and having gone back into the BIOS (with a reinstall) and trying to enable secure boot I get a message - "CSM is Loaded! Disable the CSM via Setup and repeat operation after Restart".
However there is, as far a I can see no option to disable the CSM in my bios - I've tried disabling anything related to Legacy and reinstalling both Ubuntu and Windows 8 as well as wiping the drive and jumping the CMOS as well as updating the BIOS.

Am very much at a loss and feel I've tried every permutation in the BIOS. Could possibly be an incompatibility with graphics card, but wouldn't know where to start on that end if it is.

Many thanks for your time!

Answer:Can't enable Secure Boot on my BIOS.

CSM will not always be shown as a CSM on/off option; however, the Compatibility Support Module directly relates to Legacy support. So, I would start by resetting my BIOS to defaults and then reviewing the following options:

Secure Boot

<Enter> to enter the sub-menu. This sub-menu will appear when ?Windows 8
Feature? is enabled.

Secure Boot Control [Disabled]

[Disabled] Disables this function.

Secure Boot Mode [Standard]

[Standard] The system will automatically load the secure keys from BIOS.
[Custom] Allows user to configure the secure boot settings and manually

I have repeatedly attempted to reboot after disabling UEFI Secure Boot but it simply defaults back to what it was before. I have the latest BIOS firmware AMI Version 80.52 installed but the problem existed prior to this update. I upgraded from Windows 8.0 to Windows 10 when Microsoft made it available for free installation but I did create an HP Recovery set prior to this. This I have used in attempt to restore the Pavilion 500-141ea back to its factory state but it has been an absolute waste of time because this has made no difference and I still cannot enable Legacy mode when I wish to use it. Please can someone offer a solution to this frustrating issue ... and for those that may question why I need the Legacy mode option, I like to try out Live Disc Linux Distros occasionally, some of which will not boot from the DVD drive!

I had to go into the BIOS and change the type from Secure Boot / UEFI to Legacy Boot in order to get the firmware program for my SSD to run from a removable USB drive. No big deal, I figured after the firmware is updated, I'll go in to change it back to Secure / UEFI, right?  Wrong.
So, hours later now, I cannot enter the BIOS at all. During the POST screen, I see the "Press F2 for Setup / F12 for Boot Options" and I even notice that the "F2 for Setup" become highlighted/selected after holding the F2 key down. But, instead of going into the BIOS, it goes to a DOS menu in which you can either select the OS or Windows Memory Diagnostic.  
I ended up doing a clean install of Win 10, and disabled fast boot. That didn't help. Then I thought installing Win 7 would fix it. Nope. Same deal; can't get into BIOS.  I did some googling and found one suggestion to press Alt+F2 and all combinations thereof including F8, ESC, DEL etc - no luck.  Another suggestion I tried was removing the CMOS battery / unplugging the SSD / laptop battery in order to force it to a hold POST screen.  What happened then after pressing F2 was lots of beeping and a Boot from PXE menu came up (Bizarre).

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

I have a Thinkpad T430u and I am unable to get a bootable USB flash drive to boot. I have made the bootable drive in PowerISO, I have used Window's tool, and I have also tried the following (suggested on these forums): "Create another flash drive with a single FAT32 partition using DISKPART in a command windows:  list disk, select disk, clean, create partition primary, format fs=fat32 quick, assign. " But that didn't work either. Nothing I have done has allowed me to boot to the USB flash drive. The flash drive isn't the problem, because I can boot to it on my other computers. I have turned UEFI/legacy boot to both, as well as to Legacy only, and that doesn't help. I have turned off secure boot, and that didn't help either. I have searched a lot and tried everything out there.. but nothing works. I even bought a USB DVD drive to test and see if I could boot to a burned DVD and that didn't work either. I am able to reach the BIOS settings as well as the boot device menu, but the only options available are ATA HDD and PIC Lan boot.. the flash drive never shows up as an option. I have moved USB HDD and USB FDD to the top of the boot order in bios but that doesn't help either. Any suggestions? BTW I have tried Windows 7 and 8 ISOs, as well as a Linux distrubtion and various bootable partition utilities.. I even tried Lenovo's own UEFI diagnostic created with Lenovo's bootable USB generator.. nothing will boot.

Answer:Thinkpad T430u can't boot to USB or DVD.. It's not UEFI/Legacy or Secure boot

Had the same issue. Tried on another T430u, and did the same. Defaulted Bios and checked that secure boot was desabled. It booted from the USB drive straight away.

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.

Answer:Cannot Downgrade to 7 Legacy Enabled, Secure boot disabled

Hi there

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

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.

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

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

Hello,
I tried to solve an installation problem for a friend of mine by GPT and as I tried to complete the installation, I most probably made a mistake in trying to turn UEFI boot on. I invalidated the legacy boot option and now the system does not start at all, no Dell logo nor anything else. I tried to boot on several installation DVDs with no results.

Is there a way to reset the settings I made in the BIOS ?
Is there any other solutions to boot ? Is possible that, I am able to find one, an UEFI iso image could be used to start from the DVD and go on with  the installation ?
I think the BIOS version was A11 but I am not 100% sure. Anyway, I am pretty sure I did not try to boot aother BIOS.
Is anyone can help me ;-)

Hi I can't get Secure Boot enabled on my laptop, I know most Windows 8 computers come with it enabled but for some reason it isn't.

Screenshot below

 

Answer:Can't enable Secure Boot

check in bios settings it may be disabled there, if its not there ur system didn't came with that feature, in that case u will be able to use ur system just fine without secure boot feature.

Hi I can't seem to get Secure Boot enabled on my laptop, the secure boot option is greyed out and I can't change it to enabled, my computer came with windows 8 on it automatically so I thought it would've been enabled by default.

Hi All, On my X1 Carbon, I had to move from Win 8.1 pro to 8.1 Ent. I did a fresh install from scratch to only install what I need.During my setup, I had to disable Secure boot, to boot on a USB Key, install 8.1 Enterprise. Now that everything is working, I would like to re-enable the secure boot option. If I don't it directly in the BIOS, the laptop doesn't book any more. ANy idea how to do it ? Do I have to import key from my 8.1 Ent to the Bios or something like this ? Thank youChristopher

Hi,so I have a question. I bought my Thinkpad S440 with Windows 8 (not PRO) pre-installed. About a month ago I'd had a problem with my motherboard so I sent the S440 to Lenovo. My S440 came back with a new motherboard paired with Windows 8 PRO licence, with Secure boot disabled and still running my original Windows 8 (not Pro). So I reset my computer to the factory default settings (from Windows) and now I'm running Windows 8 PRO version. So if I want the Secure Boot back...My SSD is in GPT mode, can I just re-enable the Secure boot? Did Lenovo had to replace my Recovery partition with a new Windows 8 PRO image or is it the original image but with the PRO features enabled? What about restoring Factory keys from Thinkpad Setup, is it necessary for re-enabling the Secure boot?Thank you very much!David

After running MBR2GPT on my system with a successful completion, I realized that I don't know how to change the BIOS from legacy to UEFI, resulting in the inability to boot the GPT'ed system. I was running Windows 10 Creator on an MBR system using an MSI H61M-E23 (version 2) motherboard. I made the mistake of thinking that setting the boot mode to UEFI would be easy - I tried setting the first boot device to UEFI, but that did not work. The system does not boot - all I get is a blinking cursor. Any help would be appreciated.

Hello everyone,
I am running Windows 8 x64 without secure boot enabled. According to the screen shot

secure boot is "Unsupported" but my motherboard has secure boot features in it. Its just that I didn't have secure boot enabled when I installed Windows 8 so Windows is unable to use secure boot now. What are the steps for setting up my computer for installing windows in secure boot mode ?

Pc Specs-:
Motherboard: Gigabyte H77m-D3H (rev 1.1)GIGABYTE - Motherboard - Socket 1155 - GA-H77M-D3H (rev. 1.1)
BIOS ver: F11 (Latest)
Ram:8 Gb DDR3 Corsair
HardDisk-: 1) Western Digital 160 GB (boot) 2) Western Digital 1 TB.

I had mailed Gigabyte support on how to enable secure boot they told me the following-:

"We suggest you can first back up data, reset BIOS items we mentioned in first mail, format your HDD into GPT partition and then reinstall Genuine Windows 8 to test again."

So I am asking how can I format my HDD into a GPT ? Is there anything else I need to before I install Windows 8 again ?? Please tell me the exact steps to follow.

Also, there are two things is there any app available via which I can backup my entire C drive including Program Files, all my installed apps, and all of my hotfixes and Windows updates ?? Because I don't want to reinstall everything again and again update my Windows 8.

Thanks.

Hi all, first of all I would like to provide you with some background information. I purchased (in Germany) 2 identical Yoga 11 machines (MAS29GE). Both had display ghosting issues and one of them had a lose trackpad. So, I sent them in for repair.
After getting back the 2nd one as well, I wanted to see whether the BIOS versions are identical on them, since the repair report said that there was a BIOS update performed on both machines. The BIOS version seems to be the very same I had before sending them in: v1.2.58, 05.12.2012
But then I noticed something strange: on one of the Yogas the Secure Boot State is Off. I checked it also with PowerShell and it shows False, meaning disabled.
So, I called Lenovo support, but they weren't able to help me. The answer was that I cannot enter the BIOS to change this.
However, I suspect that either the technicians entered the BIOS and forgot to enable secure boot later on, or something else messed it up. What I also noticed after receiving the Yogas back from repair is that the "Advanced Startup" in
Windows shows more options on one machne than the other. Please, see the below images for details:

I bought a brand new HP Pavillion 17G053US from Office Depot.
It came with OEM installed win 8.
I did a fresh install of win 8.1 pro x64.
I had to do this with Legacy Support enabled, and secure boot disabled.
I used an 8 GB USB 2.0 stick for the install, the win 8.1 iso image was applied using rufus 2.3.
During the install, I reformatted the HD, removing all the OEM partitions.
I also used diskpart to convert the format of the HD from GPT to MBR.
The installation seems successful, except for a strange WLAN issue (extremely limited range despite loading the drivers).
I would also like to boot in UEFI to benefit from the faster start up times, etc.
BUT if I change the BIOS config by disabling legacy support, then it will no longer boot from HD.
The resulting error message says something to the effect of "please install an OS on the HD"
I suspected that perhaps this may be due to my converting the HD format from GPT to MBR,so I converted back to GPT, reinstalled, and still, must boot with Legacy support enabled....
 
Any suggestions?
Thanks in advance,

Hello,
My Dell computer did not boot anymore. Nothing seemed to work, so I went to a friend and copied the emergency disk on a USB drive. The drive seems to work as it installs windows 10, but if I leave it in when it finished installing, it will do it again. I tried taking it out, and the black screen showed a blue window with little balls circling and the words getting ready. Well, I waited quite a while and nothing happened.
So, I started searching the web (I also have a Mac computer) and people seemed to say that I should change the booting bios and disable secure boot. I went into the bios, or so I think, but clicking on f12 at restart. I went to boot but I saw no secure boot in the choices.
I am at a loss here. I haven't used my dell since February, as that is when I had the problem. Then life happened and I did not get back to it till now.
I would appreciate some help if at all possible.
Thanks
Dalila

Hello,

I have an Asus U46E laptop (circa 2011) originally purchased with Windows 7 Ultimate 64Bit and problem free. It's since been upgraded to Windows 10 Pro 64Bit v.1607 and in all respects but one seems to be working fine. It won't launch from a rescue boot disk in the D: disk drive.

I researched as much as I could about this issue and the PC's System Information shows the BIOS Mode is Legacy and Secure Boot is Unsupported. My boot-up order shows device before HDD and every reboot confirms the disk drive is being accessed and spins the disk before moving on to the HDD. This issue apparently has something to do with Windows 10 UEFI and its Secure Boot feature, which also speeds up boot-ups.

I've tried every combination of boot-up keys, F2, F8, F10, F12, with and without shift+ and also tapping the F key or holding it down. Shift+ Restart F2 gets me into the UEFI Settings>Troubleshooting>Advanced>Startup Options> Restart but it still won't boot to the rescue disk or into any BIOS-like menu. It just continue to boo up the the HDD with Windows.

The bootable rescue disk which was accessible before updating from v1511 to v1607 was by Acronis. Now I've switched to Macrium Reflect and have created bootable rescue disks with WinPE v.10, v.5 and v.4 to see if the lagacy detail would help. None work.

I think the solution is to get into the BIOS (not sure if UEFI is BIOS) or the UEFI and turn off Secure Boot or Fast Boot but I don't see how or at least it's not follow... Read more

I just got this brand new computer and switched out the hard drive with my current SSD and 16gb of pc-12800 1.35v. Since i wasn't using a UEFI compatible bios before, I switched this one into legacy mode. When I rebooted, the computer just hung at the first screen. It will not go into bios or boot menu or anything. It will accept keypresses for the first few seconds of boot, but then just hangs saying "Entering Setup" or other appropriate messages. Switching the hardware back to the factory parts had no effect on this state. After that I started messing around and found that some older ddr3 ram allowed me to get into the bios and change it back to UEFI. In that mode, even with secure boot disabled, I cannot boot to DVD, USB, SSD, or the original hard drive. It is almost like they aren't recognized. Is there an issue with the 1.11 bios here? Thanks,Bob

At any point in the future, is a new BIOS/UEFI firmware going to be released that unlocks the selection for "UEFI" on the boot mode? I have an operating system/bootloader that would be better served with the ability to switch to a legacy BIOS style mode as opposed to being locked into UEFI only. Consider this a formal request as well, to include a legacy boot mode in a future release. I know there's quite a few of us who would consider this a very useful change.

I was working on a client's HP 15 Touchscreen and needed to boot a flash drive to perform a virus scan. It originally had Windows 8.1 instaled but had been force-upgraded to Windows 10. When I enabled Legacy Support it automagically disabled Secure Boot. I set the UEFI boot order to USB, OSD then HDD. I set the Legacy boot order to USB, OSD then HDD. Saved and exited. Laptop restarted and stopped dead, nothing but a gray screen. Fan runs but HDD is silent. Nothing on the screen, not even a blinking cursor. Power off, pull battery, disconnect AC, drain the capacitors, attach AC and boot. Same result. Power off/on and tap ESC, same result. Repeat but tap F10, same result. Connect external monitor, no video. Recover BIOS and boots perfectly from HDD, still no Legacy support. Tried just disabling Secure Boot only but it automagically enabled Legacy, and disabling Legacy automagically enabled Secure Boot. I've scoured the internet and this forum. Saw one topic with exacly the same problem but with no resolution. I no longer have the laptop so cannot give more info or do further tests. Does anyone know why enabling Legacy and disabling Secure Boot would cause this? Need an answer 'cuz I'm pretty sure this is going to be a problem in the near-future. Thanks!

Due to the issue with Windows 7 being too dark on the Ideapad S400 (backlight issue), I decided to roll back to windows 8. To install Windows 7 from our deployment server I changed the BIOS to Legacy Support., but then to install Windows 8 I changed the BIOS back to UEFI but now under FI (Boot) only the network card is listed and not the hard-drive. If I roll back to BIOS to legacy then the hard-drive is listed as a boot device. Sound like a bug. I really got the feeling that the BIOS of the Ideapad S400 is a beta. Will Lenovo issue a BIOS update in the near future? This is the worse laptop I've even seen so far!

Answer:hard-drive not listed in BIOS after changing boot mode from Legacy to UEFI.

hi bthjf1,
 
AFAIK, to see the HDD under UEFI boot on the BIOS, you must install Windows 8 in UEFI (HDD being formatted as GPT).
 
Try to:
1. Install Windows 8 in UEFI as stated in this guide.
2. Boot into the BIOS, press F9 to reset BIOS to default then check if HDD is now listed under EFI boot
 
 
Hope this helps

Hi all, I've been a long-time reader of this forum, but this is my first message. I bought last year a T420 from eBay and promptly installed Ubuntu on the HDD. Last week I bought a Samsung mSATA SSD to reinstall Ubuntu on it and use the HDD as data disk. I took the opportunity to test UEFI and enabled UEFI in the BIOS. The installation was successful but when I plugged it to the dock station I lost the USB connectivity (no USB keyboard or wireless mouse), so I decided to revert UEFI to "legacy" and reinstall it. To my surprise, once I reverted to "legacy" boot I lost the ability to boot from any of the possibilities: the original HDD or even the Ubuntu DVD install media. I've played with all the BIOS options, going back to UEFI boot, and it doesn't even detect now my installation on the SSD  I went yesterday to an official Lenovo shop and they told me it was a software issue and that reverting back to BIOS should be enough, so I downloaded the "BIOS Update Bootable CD" from: http://support.lenovo.com/us/en/downloads/migr-77076 but it doesn't boot either, so I'm really stuck and any help would be greatly appreciated!  Thanks in advance.Pablo

The problem started when i changed to legacy mode when windows installation started giving me trouble.What i think would fix the problem is to either change back to UEFI mode from windows, or to get in the BIOS menu somehow..Does anyone know how to do either of those things? any other ideas are more than welcome

Answer:z580 can't access bios setup or boot menu after changing to Legacy from UEFI mode

Anyone? u_uI was under the impression this community contained some Lenovo experts..

Hi,
I really appreciate the good design of Dell Inspiration 7353 laptop, it's good, mostly indeed.
Recently I have a problem to use legacy boot (USB, DVD/CD, Internal HD, whatever), after I have upgraded the BIOS to the latest one (Inspiron_3153_3158_7353_7359_7568_1.13.0). Due to legacy boot is required in my daily work, so I will ask for help, see if anyone can give me a solution.
When I used the laptop without any BIOS upgrade, it can boot from any legacy driver (USB, etc) with Windows 7, 8+ etc. 
Then it had a small USB issue, I thought I should try to upgrade BIOS, see if this can help, then soon I started to regret, because I had found that all legacy boot is failed, the Windows 8.1 throw me into a BSOD, tell me PAGE FAULT error. I have tried USB, internal HD & DVD, all same.
Then I googled, saw someone had similar problem (not same), he cleared CMOS by pull out the battery, so I tried it without any hope, but surprisingly, when I pull out the battery and remove the connection of power adapter and laptop battery, by pressing the power button several time with & without power cord connected, then I installed the CMOS battery, laptop battery, restart the laptop.
When I press F12 to load the boot menu, it really can load legacy bootable device, but that's one time thing. After the system reboot, the problem back again, looks like if I want to boot into legacy bootable device, I will have to remove CMOS battery each time like above all...sad.

Best I can tell the documentation HP publishing specifying the method required to disable Secure Boot on an Envy 700-074 was written by someone(s) who had no experience in implementing the methods they list.  IT DOES NOT WORK!  The ONLY way this machine will boot to the harddrive or to a bootable CD/DVD is if SECURE BOOT IS ENABLED. I have spent literally days trying to get it to work.  Formatted harddrive as MBR not uefi, gone through the truly bizarre methods required to get the computer register in bios that I wanted the DVD drive as the first option, F10 and Escaped innumerable times.  Bottom line, whoever designed and implemented the bios on the Envy 700-074 MUST be kept away from future involvement on bios implementation!

Okay so recently I purchased some mods from a website and have to disable secure boot and boot off of slightly modded version of Windows they provide. But I have an Asus motherboard and am not allowed to simply turn off secure boot. So I followed a tutorial and when I got to the end it said to delete the platform key. It also gives me a warning saying it'll be in startup mode after deleting the platform key. I do not know if this is safe to do or what these keys are even for. I already saved the keys on my USB and am wondering if I should delete the platform key to disable secure boot?

Hello, I'm trying to enable legacy  boot on my HP 20 all-in-one PC and I'm running into a bunch of trouble. So first of all here is what my secure boot settings look like  As you can see secure boot should be disabled here, but there is no option to enable legacy boot as it's shown in the guide on the HP website. When trying to change boot options all that I run into is this  and pressing F5 gives this error message   I'm also running the latest BIOS version that I could download on the HP drivers page  Please help me solve this specific case while knowing that I've already read This guide, and thank you in advance.

I've tried changing boot priority multiple times to have my CD/DVD drive boot first & the SSD second & 3rd disabled.

But it doesn't ever seem to save the settings and does NOT boot from the CD/DVD and instead goes directly to the SSD, either my Ubuntu or my Win7 SSD, whichever one I happen to have hooked up at the time.

Anyone know what the problem & solution is? This is getting very frustrating, I've been trying to do this for a couple weeks now and just no luck. I've tried multiple Secure Erase DVDs, one made through Samsung Magician & one made manually with an iso burner, both gave me same results regardless of SSD Ubuntu/Win7

Answer:I cant find BIOS and disable Secure Boot

Hi: Your notebook does not have a UEFI BIOS, so there is no secure boot feature to disable. If your notebook has an Intel processor and chipset, you need to install the applicable sata achi driver in order to install  Windows XP. See the link below, read the Intel section and then read the downloadable document for how to slipstream all of the drivers. http://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/SATA-drivers-for-XP-solution-on-... If your notebook has an AMD processor and nNvidia chipset, you should just be able to install XP with no problem. For Intel, you would need the XP 64 bit drivers to slipstream which I have zipped up and attached below.

You will need to add the Secure Boot authentication code to the UEFI/BIOS firmware settings. If want Secure Boot ENABLED.

I have an Acer Aspire M3450 with a FX cpu. I just read that windows 10 will need a UEFI bios that supports secure boot. There is a update listed on the Acer site PO1.4A. Does this update contain the updated UEFI? The system I have now has UEFI but is 1.3 I believe and the new UEFI is 2.4. I have run the upgrade advisor for windows 8.1 and it tells me the same thing about my version of bios and no secure boot.

Hi
 
I had PUM.dns latch onto my computer and I've tried secure erasing the SSD. However, even that has not stopped the issue of it inviting various trojans back onto the computer.
 
I remember seeing a message - 'Secure Boot Violation: The system found unauthorized changes on the firmware, operating system or UEFI driver...' and considering resetting/flashing the Bios to see if I can remove any potential issues with its integrity.
 
Would anyone know if this is effective or recommend a better way in dealing with this issue? 
 
I have an ASUS Z97 and they do have this flashback option with a USB. Is that useful?

I built a computer back in 2009 with an Intel DP55KG motherboard running Windows 7. So, I am getting ready for a fresh Windows 10 install and I noticed that back in 2009 I never enabled the UEFI boot mode. Would it be recommended to enable it this time before the Win 10 install, or will it bring about some issues? I also have 3 other hard drives in this computer with various flavors of Linux.

Here is the definition of the setting according to the motherboard manual:

UEFI boot


OPTIONS: ? Enable ? Disable


Enables or disables Unified Extended Firmware Interface (UEFI) Boot. UEFI Boot must be enabled in order to boot to a drive larger than 2 TB (terabytes). Enable: BIOS will attempt to boot via UEFI before using the legacy boot sequence. Disable: BIOS will use the legacy boot sequence.
