Cannot change UEFI settings / UEFI stuck in read only mode

Q: Cannot change UEFI settings / UEFI stuck in read only mode

I need to change some setting in my UEFI/BIOS but it is stuck in ready only mode.
All options are blanked out except for "exit". How can I get it to let me edit the settings again?

Preferred Solution: Cannot change UEFI settings / UEFI stuck in read only mode

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.)

A: Cannot change UEFI settings / UEFI stuck in read only mode

You may have to disable the "Secure Boot" option first.

Hello, I have a Y720 tha comes with a 1x 129 GB M2 SSD and x1 HDD, in UEFI mode. I'm currently trying to replace the M2 SSD with a newly bougth Samsung 960 EVO M2 where I would like to install Windows 10 also in UEFI mode, as it has better power management than Legacy. But I have tried booting the Windows 10 installer USB stick and the laptop does not recognize in bios. I have created the usb stick with RUFUS 2.18 (latest), choosing UEFI + GPT and Fat32 file format. Before that I also tried restoring a system backup image I created from the former M2 using AOMEI Backupper but I couldn't boot the USB utility to do so either (the same happened: Bios does not recognise it, despite creating it choosing UEFI mode) Things I have tried: 1. Disabling secure boot (although the Secure Boot Status staed "Enabled", so I used the "REset Secure Boot mode" option too...)2. Chaging Optimal OS Setting to disabled in seetings, but still no use3. Using the Novo Button on the right part of the laptop. Of course, changing boot mode to Legacy would allow me to install Windows from USB ....but in Legacy mode, which I'm trying to avo So ...is there a way to boot a UEFI usb stick to install Windows in UEFI mode from it?  thanks!

I am not sure if this subforum is the right place, if not, pleases help me transfer to the right forum...

I recently just build a new setup with Asus P8Z77-V LK, this motherboard comes with UEFI boot and legacy BIOS boot support.

So I tested install windows 7 in both mode, and I didn't find any advantage of UEFI consider it is a new technology been promoted quite a lot for recent years.

The benefit I found is: a graphic BIOS setup, which is useless to most users if you don't OC. Even you did, I still find using keyboard to navigate through the menu is much easier than mouse.

Faster boot time? very negligible, could be 31 seconds compare to 28 seconds. As I timed use my stopwatch, the value could include a few seconds human error as well.

Support boot from > 2.2TB HDD? nowadays most user use SSD as boot drive so this really doesn't matter.

GPT disk partition? don't see any benefit here compare to legacy MBR...

Anyone can enlighten me what is the advantage of UEFI here?

Thanks a lot!

A:What's the benefit of UEFI and install Windows in UEFI mode?

Thanks for adding information about EFI BIOS which present a problem for many during installation and repairs.

For this reason alone, I would advise disabling EFI BIOS in BIOS boot order or choosing Legacy BIOS in BIOS setup, installing normally to an MBR disk.

Wiping a HD already formatted as GPT disk with Diskpart Clean Command can clear the way for it to install as MBR. Sometimes it also takes runnning the command "Convert MBR" to change disk from GPT.

Hello community, I cannot change any settings in my UEFI on my B50-70 Notebook.The last thing I installed was ubuntu, now I wanted to install Windows 10 again.I cannot boot from any UEFI USB/CD/HDD anymore, it still has ubuntu as the only UEFI Boot entry.It says "cannot boot ubuntu" all the time, but It doesn't accept any changes to the boot order.Also removing the battery or the HDD doesn't change anything. It still wants to boot to the "ubuntu" boot entry.Loading default settings does nothing. All settings are like before after reboot.I still can boot in Legacy mode though, but I always need to hit enter to confirm the "cannot boot ubuntu" dialog.I have the lastest UEFI Firmware installed (3.04 or so). Now since I cannot change any settings or boot entries, I think the chip where all settings are saved is somehow burned in all the settings forever. I tried many EFI Boot sources, these work on all other notebooks/pcs, also they worked on this notebook before. Is there any way to read out which .efi file it has set for the entry "ubuntu" from a legacy booted OS? So I could make a workaround by placing the Windows bootloader to the same path with the same filename. Thanks in advance.

I know it isn?t the best section to post, but there is no sub forum for my computer serie (Satellite NB10T) and this problem is linked with Win 8
I'm stuck at the moment: I disentailed win 8 because I want to come back to 7

I'm aware of
The problem is that I don't have Boot mode option under advanced- system configuration; the only thing I can do is enabling or disabling secure boot mode in the security tab, which is not enough

I also added a supervisor password; it does add a clear secure boot keys option, but still nothing under advanced tab to switch to Csm.
Clearing keys does not work too.

I tried to boot multiples linux distro and win7 on bootable usb (theses work on others computers), but no luck. Boot order set to usb first of course).
What can I do?

You have to update the BIOS.

Upgraded Video Card from GTX 560 Ti to GTX 1060 Strix, machine boots but no video output or just black/blank screen.

1. Change PCI setting to Legacy in BIOS/UEFI
2. Update to latest BIOS.

I decided to try and update BIOS to latest BETA (13w) using @bios from Windows. Everything went ok, reboots fine and still does now with Windows loading no problem, BUT i can't get to BIOS/UEFI???

All i get is the UEFI empty blue screen, no menus/options, just blank screen...

So i thought maybe i can reverse back to previous BIOS from windows but program wouldn't allow this. I tried sticking BIOS file in USB but the problem is i can't get to BIOS.

I Have tried running backup BIOS as board has two, but still same problem.

Hello all,

This is my first post. I am a Windows 7 user and now (against my will) Windows 8.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

Trying to understand handshaking between UEFI & Win 7. Have Win7 Pro sp1 64 installed on SSD, mb=Asus F2A85-V Pro. Example: boot to flashdrive to do Acronis backup of SSD; remove SDD, insert spinner; boot again to flashdrive to do Acronis restore to spinner (to test backup); remove flashdrive, boot to UEFI, set UEFI spinner as default, save & reset; spinner starts boot (#1), Win logo shows briefly, reboots (#2) and shows Win repair/normal screen; choose normal; Windows desktop shows; new driver is loaded for spinner and asks for reboot (that part I understand); reboot (#3) starts and again briefly shows Win logo before yet again rebooting (#4) to the Win repair/normal screen; again choose normal & all is happy. But then I remove the spinner, insert the SSD, and have to go through the whole deal again. Why so many reboots?

Similarly, if I change any hd/flashdrive configuration, my UEFI boot selection is lost & I have to reset it again - sometimes with the multiple reboot scenerio, sometimes not. Sure wish I could force that the UEFI selection stay there as long as the selected drive is installed.

A:UEFI boot keeps changing; UEFI/Win7 handshaking confusion

Hello and welcome diana look I am having a little difficulty in following the train of the thread.

Now do you mean you just backed up the SSD to a USB stick ? then tried to transfer that USB stick back up to the spinner? If it was just a back up then I don't think it is going to work because it is only a backup.

To make the spinner the boot device I would be cloning the SSD to the spinner. I wouldn't mucking around with sticks as I cannot see why that is necessary.

The short answer to the headline?s question is that a UEFI scanner is all about helping you protect your computer against people who seek to take it over by abusing its Unified Extensible Firmware Interface (UEFI). A successful attack on a system?s UEFI can give the attacker complete control of that system, including persistence: the ability to secretly maintain unauthorized access to the machine despite rebooting and/or reformatting of the hard drive.

As you can imagine, this form of persistence is not a virtue and can prolong the pain and inconvenience of a malicious code infection. If your security software only scan drives and memory, without scanning UEFI, it is possible to think you have a clean machine when you don?t, that?s why we recommend a security solution that scans it, like ESET.

Why does my device have a UEFI?

Computing devices work by executing code: the instructions that we call software and which make the hardware ? such as a laptop or smartphone ? do something useful. Code can be fed to the device in several ways. For example, it can be read from storage on a disk, held in memory, or delivered via a network connection. But when you power on a digital device it has to start somewhere (bootstrap), and that first piece of code is typically stored in a chip on the device. This code, referred to as firmware, may include a ?power-on self-test? or POST to make sure things are working correctly, followed by the loading into memory of the basic in... Read more

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

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:

SEL DIS 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

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.

Hi everyone
Some people might like to test the possibilities of UEFI systems even though their current machines aren't equipped with it.

It IS possible to do this in a Virtual machine even if the HOST system is a non UEFI machine.

Edit Manually the VM configuration for the VM you want to test this feature with.

Add the following like to the .VMX (machine configuration file)
firmware = ?efi?

Note that you must do this BEFORE installing the VM and you can't change it afterwards.

Dear Friends,

Long time reader of this forum but a first time poster, so please forgive me if this question has already been asked and answered.

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...I find this kind of odd. 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.

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?

It is a very important security feature.

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. This way, the system knows all the files being loaded before Windows 8 loads and gets to the login screen have not been tampered with.

Hi everyone,

I'm attemping to install Windows 7 64 bits in a Sony vaio SVE14A25CLB laptop. Many threads in this forum already help me a lot to change the UEFI settings to boot from a DVD or USB device in UEFI mode and I clean the hard drive with diskpart. Also secure boot is disabled.

My System specs:
Sony Vaio SVE14A25CLB
Intel Core i5 -3210M, 2.50GHz
Sony Vaio Intel HM76 Express Chipset
Intel HD Graphics 4000, AMD Radeon HD 7670M 1GB
HDD 750GB, 5400 rpm

My next opponent in this journey is while windows setup is loading the files, on UEFI mode, it just stop at loading the disk.sys file (checked in safe mode), but in Legacy mode (BIOS) the windows setup (DVD or USB) start without issues (this is how I managed use diskpart).

I don't think it could be due to hard drive or memory issues (I didn't run any tests yet), as the windows setup start normaly on Legacy mode and It install successfully Windows 7 on a MBR partition.

From factory, the laptop comes with Windows 8, but even if the general performance is very good, it was some "features" that bother me. So hard drive already has GPT and I want to keep that partition table mode in case I need to do a dual boot with windows 8 in the future.

After clean the hard drive I even created GPT partitions following these steps:

A:Windows 7 setup stop in disk.sys on UEFI mode, but in BIOS mode it did

Sony boot key is F12.

Make sure you have followed Option One in UEFI Bootable USB Flash Drive - Create in Windows
to create the flash stick.

To install Win7 in UEFI mode sometimes requires some level of CSM or Legacy set in BIOS, even "Boot UEFI First." You will need to scour those listings, post back camera snaps of all available choices for UEFI, Legacy, CSM, and boot order. Are you choosing UEFI device to boot. That would point to the media being the problem.

At Eight Forums they can help you derive your Product Key so that you can reinstall 8 to an MBR disk using media they should also be able to link you to. This is providing the BIOS won't auto-activate on MBR. These mysteries are all shrouded in EightForums which I will get over to one day when Win7 stops being the most popular OS and keeping us so busy here.

I just cleared my bios. However, now when my PC boots, it just goes to this screen that shows the following...

CMOS Date/Time not set
Press F2 or DEL to run setup
Press F1 to continue

However, the PC is not responding to me pressing any of those keys on my keyboard.

I have tried 2 different keyboards, and tried them on every USB port each.

Please help?

After resetting UEFI to default values, I can't start WIndows because boot goes to UEFI.

The story is this:

I wanted to make a clean install of W10 and for that I had to make some changes in UEFI because it wouldn't allow me otherwise. But after the installation I see that I have some problems with the sleep and fast boot, not working well. So I went to UEFI and reset it to default, saved and exit. On boot, it goes to UEFI once and again. Windows doesn't load.

So I have to do the same changes that I had to do for installing W10. Disable fast boot, etc. And then yes, I get to Windows, but keep having the same sleep and boot problems. Both work really bad in different ways.

Does anybody know what is wrong?

PS: I also did other changes, by the way. I couldn't install W10 because it said that my disk was GPT partition style, so I had to follow some instructions to change that, which wiped my disk and partitions completely and maybe I missed some step...

Thanks in advance.

Please post a screenshot of disk management. Also, make sure your boot option is listed as Windows Boot Manager if you are installed in UEFI mode (which the screenshot above will show).

Hello all,
My system specs are the following: Windows 10 Enterprise 64-bit UEFI Bios Phoenix BIOS version and drivers are updated, also confirmed by Slimdrivers. Samsung Series 5 ULTRA 530U4C-S02PT Also: It is an hybrid drive, 1TB HDD & 24GB SSD that is supposedly well installed (the laptop never been so fast after formating and installing windows 10 with express cache to take advantage of SSD hybrid boosting). Windows works like a speedster the only problem is the inaccessibility of BIOS, for example i want to enable the virtualization VT-X to install Oracle VM and i can't go BIOS to edit virtualization.
Problems: UEFI BIOS firmware settings boot dialog is inaccessible.Not working suggested fixes:

i) hotkeys Esc, F2, F4, F8 and F10 don't log in BIOS. Although safe mode, debug logging, etc are available. Disabling Fast Bios in the control panel > power management dialog doesn't do anything.ii) automatic repair seems to give an error, after the account is specified in the repair boot dialog it gives error.iii) recovery > Advanced options > UEFI Firmware Settings Boot is not Visible.iv) EasyUEFI free only works with Windows 10 Home, not Enterprise (it would resolve the issue appropriately with the boot into UEFI option) Sources:
Cause (according to internet forums): i) Probably my uefi has Secure Boot Enabled and Fast Boot also, making the boot system almost instantaneous and rendering other boot scenarios blocked. Because system is only seeing the SSD drive as b... Read more

Hi All,

I'm having my first encounter with UEFI on a new(to me) HP Laptop with Windows 8.1. (excuse the noobiness)
I have read/Googled quite a bit and am trying to understand.
If I understand the basics of the UEFI BIOS and "Key" and OS/Software needs a matching "Key" to be able to install.
I understand that along with this, there is a new method of partitioning "GPT" to support the UEFI/Safe Boot/Key.

To my questions/quries,

1. I have a set of "Full Recovery Disks",
Which I assume are able to put the Laptop back to original even if disk is replaced,
So the recovery disks will re-create the disk partitions(GPT?) to work with UEFI..??

2. I want to be able to boot from USB to try Linux Live boots.
From what I have read, I need to disable "Safe Boot", and enable "Legacy" mode, is this correct..??
I do understand this will bypass the extra security that "Safe Boot" brings.

Not sure if I should do another post for this one, but here goes.?
I have a Retail Windows 8.0 Pro Install disk, unopened with Key.
Can I install that on this Laptop, or is it only for use on a machine with No OS.?
If it's a YES, am I right to assume that if I removed all partition from the disk, like it was new,
It would create the necessary partitions/format to work with the UEFI BiIOS..??

Many Thanks

Hey guys,
So Im trying to install a new graphics card, and I have to tweak some settings in the bios. Unfortunately, when I try to open it(pressing escape at startup, scrolling down, and selecting uefi settings and pressing enter) nothing happens. I looked this up, and it said to go to advanced startup and go through some steps to get to a menu that supposedly contains "uefi firmware settings". Now, I confirmed that this is the right menu, but the option is just not there. I thought about updating my BIOS, but there are no updates for it available.
Does anyone know what do?
Thanks in advance

I am really confused on what settings are required in the UEFI Bios to run recovery USB/ disks or Linux live CDs.
It all used to be so simple. The manufacturer helpdesk seems unaware that it supplies UEFI systems - so I am working blind. Have tried boot CDs and USBs but all have booted straight into Windows to date.
Perhaps there is a basic guide but I have not found one yet.
I don't wish to change settings I have no understanding of.

I have a Medion /Lenovo desktop with an AMI UEFI Bios (12 July 2012) and Aptio Setup.

The following seem relevant are supplied as enabled in "Bios":

Intel Rapid Startup Technology
Quiet Boot
Boot Select Mode [UEFI]
UEFI Hard Disk BBS Priorities - Boot Option #1 - Windows Boot Manager
Secure Boot - Secure Boot Mode [Standard]

What do these all mean and what effect do they have on how Windows 8 runs and how boot drives run?

A:UEFI Bios Settings for Windows 8

To boot a DVD/CD/USB drive, the bootable software DVD/CD/USB disc need have full supports Windows 8, UEFI, GPT & Secure Boot & signed by Microsoft.

Boot the disc in UEFI mode from the One Time Boot Menu, check your manual for the F? key.

It started when I took one of my hard drives out of my case. Now when I turn it on, it will open up the UEFI Bios page instead of booting like normal. I have tried turning everything off and back on, taking out my hard drives and reinserting them, resetting some options on Bios, but to no avail. It ONCE booted into Windows, but then wouldn't let me through.... it locked me out? PLEASE GIVE ADVICE, I WANT TO DIE BECAUSE IT'S SO FRUSTRATING. NOTHING I FIND ON THE INTERNET IS WORKING.

A:W7 will not run in UEFI mode.

Hi @linv, Thank you for your query. I understand that your notebook came with Windows 10 preinstalled and you have chosen to install Windows 7.  You have updated the drivers but the performance is buggy. What is the exact difficulty you are having?HP has not tested Windows 7 on your notebook and therefore does not provide the drivers.  Computer manufacturer's can  and do alter some drivers to perform correctly with the system.  Therefore drivers obtained from the manufacturer of the individual part may or may not work as expected.  The Windows 7 installation disk, is it a registered retail copy or one that was downloaded from the web? Have you run the Windows troubleshooter? Have you done all your Windows updates? Have you downloaded and run the  HP Support Assistant?  Have you checked for viruses and malware? MS Malicious Software Removal Tool. Here  are two  link that may also help. HP PCs - Computer Is Slow (Windows 10) and HP Products - Common Solutions for Windows 10.Please let me know the outcome.Thanks!

i installed windows in uefi mode in my 250gb hdd (converted to gpt). installation succeeded. but when it restarted, it went to a boot loop.when i remove 500gb hdd, it boots normally.
please help me, i have important data in both hdds

A:uefi MODE

A Windows UEFI install does not like extended partitions on internal or external drives. You will need to find some way to remove or convert the Extended partition.

Testing right now seems to indicate Windows 8 is more tolerant of Logical partitions than Windows 7....so I need to put this on hold for now.
