Yoga 2 11 Legacy BIOS Boot Mode vs Locked in UEFI

Question: Yoga 2 11 Legacy BIOS Boot Mode vs Locked in UEFI

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.

Preferred Solution: Yoga 2 11 Legacy BIOS Boot Mode vs Locked in UEFI

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.

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

Hello, currently I have the upgraded Windows 10 Pro Spanish 32-bit activated from Windows 7 Spanish OEM 32-bit on a 2011 HP ProBook 6550b LATAM which I guess has the digital entitlement since no keys were entered. I would like to clean install & format the drive using the USB Windows Pro 10 media and have 3 questions:

Q1: checking in System Information is says the OS was installed in BIOS Legacy Mode but in the Boot menu there is an option to select UEFI instead. Which one is the best?

Q2: if clean install is done with an English US version instead of Spanish will I loose the activation?

Q3: I tried changing the display & speech language option to English in my current Spanish OS, rebooted several times and get the persistent Windows Search "these results may be incomplete" error after Indexing is completed as reported in other threads while it works fine when reverting back to Spanish display mode. Anybody knows if that bug is solved in the anniversary update?

I have lenovo g580. in bios setup under boot tab, it says UEFI boot 'Enabled'. but when i go to cmd and type 'msinfo32', it says my system has LEGACY bios mode. what actually is it? if i have UEFI mode enabled, why it shows legacy in msinfo32? please help........

Answer:BIOS mode-UEFI or Legacy in Lenovo G580?

hi firozmkhatri,
 
According to this FAQ, the UEFI BIOS has to emulate legacy BIOS so that existing applications aren't broken (this means 32bit programs since UEFI only works with 64bit versions of Windows). If you have UEFI enabled under BIOS and see it's saying Legacy under msinfo32, you probably have a Windows 7 system installed on legacy mode as the Lenovo G580 supports UEFI with an emulated Legacy.support.
 
To check if you have Windows installed on UEFI (GPT) or Legacy mode (MBR), check your drive volume:
1. Click Start, right-click Computer and then click Manage
2. On the Computer Management window, choose Disk Managemment
3. Right click on any of the Disk (i.e. Disk 1), choose Properties and on the Volumes tab, see Partition Style

Answer:Clean install in BIOS Legacy Mode or UEFI?

Q1 - more secure to use UEFI mode if supported
Q2 - clean install should use the same language version (Spanish). I'm unsure if you could use the 64 bit version rather the the 32 bit
version.
Q3 - don't know

Hi, I bought a Lenovo Thinkpad Edge E320 with 128GB SSD but without OS. I installed Windows 7 and ubuntu and had issues with dual booting because of the UEFI. So I decided to change from UEFI to legacy mode in bios. After that I cann't enter BIOS any longer. If I press F1 on start I get "Entering BIOS Setup" but the BIOS doesn't open instead immediatly Windows starts. The same with F12 to select the boot drive selection the message appears but the menu doesn't open instead Windows starts. How can I enter again the BIOS or reset the options? I tried BIOS Update with BOOT Cd from Lenovo support site but it didn't help. Thank you for advice Best regards bubbas

Answer:Edge E320, can't enter bios after changing from uefi to legacy mode

Hi bubbas and welcome to the Community,
 
This is a long shot, but take out the hard drive, the battery and unplug the ac adapter and hold the power button down for about 15 seconds.
 
Then plug in just the ac adapter without the battery or hard drive and start the machine and see if you can get into the bios.
 
If you can, reload the defaults and reboot.  See if you can get in again and you might want to check the F12 to see if that works.

Used rufus to burn image to usb, made sure that is gpt as well. For fun, tried the system restore function, but fails right away. I just deleted the windows partition (not the entire drive).

Answer:how to boot usb in uefi mode (not legacy) for inspiron 3531

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.

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.

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

I have been trying for days to install Windows 7 on my new Yoga 11s in dual boot configuration with 8.1, with no luck.  Typical catch-22 problem -- can't boot from the install media in UEFI mode, and if booted in legacy mode, Windows won't install on GPT partition. I followed all the steps everywhere mentioned:  disabled secure boot, set boot mode and order in every possible combination, etc.  I followed these steps exactly to create a UEFI-bootable USB drive:http://forums.lenovo.com/t5/Windows-8-and-8-1-Knowledge-Base/Why-can-t-I-boot-from-a-USB-key-on-UEFI... I can boot easily from the USB in legacy mode, but in UEFI mode, when starting the machine, the USB is ignored.  If I go into Windows 8.1 recovery and do an advanced start and choose EFI USB, the machine thinks for a moment and then says: "System doesn't have any USB boot option.  Please select other boot option in Boot Manager Menu." Then I click OK and it offers only one option on the menu, Windows Boot Manager. I don't know if the lack of boot options is just a symptom of the USB not really being UEFI-bootable, or some other steps are needed to add boot options.  I even tried adding an item within the windows boot manager, but that didn't work, because even if it could work in principle I don't know the right settings. Has anyone actually made this work?  If so, what is the secret?

So before sending it to repair I made an image backup, - just in case.

After ten days the computer computer came back with a scrambled hard disk with at note saying that it was an software error, although it was no doubt an hardware error because it worked perfectly with an external monitor.

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 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.

Answer: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.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

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

But if "UEFI" mode, looks like the system has ignore my boot cd, and go straight to windows 7 64 bit. Has anyone solve this problem? Will somebody help me to solve my problem? Thanks anyway

Answer:if UEFI mode on Bios, Cannot boot from CD... :(

You can install 32 bit to an EFI BIOS but it has to be in Legacy mode, with EFI Boot disk removed from the BIOS Boot order, and the HD wiped with Diskpart Clean Command so installer can reformat it from (EFI formatted) GPT disk to the normal MBR disk.

Follow these steps to get a perfect normal Clean Reinstall - Factory OEM Windows 7.

This weekend I will try to do a clean install of Win 10 again, from Win 7. Have to try som new methods to see if I can get my computer running flawlessly with Windows 10.

I will use the clean install tutorials from this forum. I hav two options, with or without UEFI installed?

What about this thing with EFI, UEFI, Legacy BIOS? How much impact will this have on my computer regarding a flawlessly Win 10 setup?

I don't know anything about this, other than UEFI is the newest standard regarding BIOS.

When I look into my boot setup, it says, 1. Boot Device - [EFI Device].
If I open Diskmanagement, this is the picture:
Should I use the tutorial with or without UEFI when I do a clean install?

Answer:EFI, UEFI, Legacy BIOS.......

Your OS seems to be currently installed in Legacy Mode, that means your drive is probably formatted using a scheme called MBR. For Windows to boot in UEFI mode, it required the drive to be formatted using a different scheme called GPT.
If you can, backup the drive and reformat it to GPT if you want UEFI.

As far as the benefits go, Legacy is old, UEFI is new. It's faster, looks prettier while booting :P. Thats pretty much it for the average consumer.

Answer:Changing UEFI mode to Legacy mode

Hi, If your HDD has a guid partition table, the current OS will have to be installed in 'uefi' mode - the only way around this would be to reformat the drive with MBR and reinstall the OS using a boot option ( cdrom or flash drive ) that does not have a (uefi) suffix. Regards, DP-K

Hi,
I recently bought a hp pavilion 15 au038ca model. It came with a lot of bloatware so I decided to clean install Windows10. I used Windows Key Finder software to find my key since it's embedded in the bios, wrote it down and went ahead to install the same version as my previous windows: Windows 10 home x64.
Before I even started with the installation, I could not see my device in the boot options( I was using a bootable usb drive). So I went to the bios and enabled legacy support and when I switched my laptop back on into boot device options, there it was: a usb drive option. So i selected it and went on ahead to do a clean install of windows. Now the problem is, whenever I load up system defaults in bios and save it, my laptop does not boot into windows. It gives me this error:

Boot device not found.

Please install an operating system on your hard disk.

Hard Disk - (3F0)

...But as soon as I enable Legacy mode, it boots up into windows. My question is, how do I install windows into uefi mode and not legacy mode? Because I read many articles saying that uefi equals faster boot times and has more advantages than the older legacy mode. And whenever i try making a bootable uefi disk, there is still no device options when only the uefi mode is on. But when the legacy mode is on, then I can see my disk under the boot device options.
Second question, how do I change my hard disk partition to gpt from mbr?
Thank you

I want to wipe a Windows 8.1 laptop and clean install Windows 7 from a CD. Laptop is an ASUS X551M.
I understand that with Windows 8 you have this UEFI, which needs to be changed such that you can change the boot order.
Following online instruction says to hold Shift whilst pressing restart then going into troubleshoot, advanced options, UEFI Firmware settings then restart (on the blue screen).
Then in the UEFI Bios Disabling the Secure Boot Control in the Security tab. Ive doe this but it also says in the Launch CSM option to change to enable. Problem is this option is not showing. So how to I change to Legacy mode so that I can change the Boot device order and boot from the CD?

Hello,

Right before I performed a clean install of Windows 8.1 x64 on my Inspiron 3520, I switched to the Legacy BIOS *facepalm*.

When I enter the legacy BIOS and enabled "secure boot", I performed a restart that gave the following message "internal hard disk drive not found, to resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 enter setup menu, F5 enter PSA". Of course, when I go back into the BIOS and disable secure boot, it reverts back to legacy and boots up Windows 8 just fine. What I'd like to know is, how can I revert back to UEFI so I can change the boot-up option and perform a clean install under UEFI.

Any help would be greatly appreciated! I've found a couple articles but I just want to make sure I'm headed in the right direction and if maybe there is a safer and easier way to get this done...

Whats the Different with Legacy Bios / UEFI ?













Solved!

Go to Solution.

Answer:Whats the Different with Legacy Bios / UEFI ?

As for the questions about UEFI in general - basically, UEFI is a replacement for BIOS. Without going into technical details, the most important difference is that UEFI is 64-bit, while BIOS works in 16-bit real mode. This adds certain amount of latency in the boot process (and resume from sleep) because your 64-bit processor will simulate 286 CPU from the power on all the way until your OS starts booting, only then your OS will switch it in 64-bit mode. New Windows 8 PCs don?t include the traditional BIOS. They use UEFI firmware instead, just as Macs have for years. Rather than have modern PCs wait several seconds for a key press and delay their speedy boot process, you?ll have to access a boot option menu after booting into Windows.

Hello,

I've installed Windows 10 and Ubuntu using UEFI.
But, now I created a bootable USB for a Linux that does not support UEFI, but only Legacy.
I mean, when I plug the USB to my laptop, the UEFI does not recognize it, only the Legacy BIOS does.
Is it possible to simply proceed to install the other Linux using Legacy mode? Or it will cause problems?

Thanks

Answer:Installing some OS's in UEFI and some using Legacy BIOS

I am never a fan of using dual boot. I have Windows 10 installed on a separate GPT SSD and Linux installed in MBR SSD and run them separately using Boot Menu so they are completely independent from each other.

I did mention in your other thread that dual booting using MBR is preferable which you can set the Windows boot manager and GRUB boot loader separately. The traditional way is Linux override the MBR and took over the booting process for both Windows & Linux. The non traditional way is to put the GRUB Boot loader in its own partition then use Easy BCD to set up the dual boot, this way they are independent so if there's an update/upgrade from either one, you won't break anything. In addition, you'll get a nice GUI dual boot Menu from Windows, not the ugly GRUB.

Here's an example:

GRUB controls the booting process for both Windows and LinuxPut GRUB in its own partition and use Easy BCD to set up dual boot.
NOTE: During Linux installation, you have to tell Linux not to use sda (MBR in Windows) but its own partition.

This computer came with WIn7 and was upgraded to Win10. I would like to make it a dualboot (with Windows as the MBR) with Ubuntu. However, My BIOS is "Legacy" and I already have 4 partitions (the unused space is not usable by Linux). Can this laptop's BIOS be upgraded to UEFI without reinstalling Windows (I want to preserve all my applications and settings in WIndows). If so, can you point me to instructions in detail? If not, recommendations for any alternatives, such as what to do (& how) with the 3 partitions other than WIndows (C: is the main WIndows partition of course; D: is Recovery; I have no idea what the other two partitions are since they do not appear in Explorer and E: is the DVD).

I have a 250GB GPT SSD and installed Windows 10-64bit in UEFI mode.

Also,

I have 1TB MBR HDD and installed Windows 7-32bit in BIOS mode.

Currently, I have to go to bios setting every time and change boot priority manually in order to boot from another windows. Is there any way to use Windows Boot Manager (dual boot) instead of selecting manually from mainboard setting?

Answer:Two Windows on Two different mode (Bios & UEFI) How to dual boot?

Other then reinstalling W7 in UEFI to a GPT drive, or reinstalling 10 in Legacy mode to a MBR disk, then no.

You`ll have to keep switching, you are going to have to choose a bios method and stick with it if you want a true simple dual boot.

I would consider the way you`re doing it a real hassle and wouldn`t think twice about fixing it correctly.

While trying to fix a boot error (0xc0000034) on my laptop I accidentally changed my computer's BIOS from UEFI to Legacy, is there a way to change it back?
The computer is clean so it doesn't matter if it's a method that causes loss of data. I have a bootable USB with windows 10 (maybe 8) on it.

And when I got to the menu for installing windows, I got the error message "windows cannot be installed on this disk. The selected disk is of the GPT partition style." so I couldn't get past from there anyway
The computer is an MSI GE70 2QE

(UEFI, Boot Order, Secure Boot Enabled)Then i have used CFGWIN.exe to export my settings to a txt file CFGWIN.exe /c /path:c:\settings.txt Now i want to use this configuration on all other Lenovo computers, without going in to BIOS and change all settings manually. So in my OS deployment i run:CFGWIN.exe /r /path:c:\settings.txt (after that i reboot the computers and continue with OS deployment) But BIOS are not set to UEFI, Secure Boot is still disabled? Please help! Sorry Wrong Thread, how do i change?

I have a client that will be migrating to windows 10 and is try to find out if systems with legacy/UEFI bios can be switched from legacy to UEFI using HP bios configuration tool through a task sequence which ultimately will install win 10 64 also. Basically can this be totally automated.

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. It works fine in legacy mode.  To get around the NTFS issue, create the flash drive in NTFS then copy the contents to your hard drive, quick format the flash drive to FAT32 and then copy back the contents back to the hard dr...

Hi everyone, I'm trying to set up a dual boot on my X220, but can't seem to get it working.I tried to follow the tutorials available on ThinkWiki about SSD partitions and optimization, but it didn't work.Also, I'm a bit confused between MBR and GPT, and UEFI and LEGACY, and Syslinux and Grub.From what I read, it seems we're supposed to use GPT partitions with UEFI boot, which is what I'm trying to set up. Have any of you successfully set up a dual boot Linux (Arch) + Windows (7 home) on SSD and HDD?If so, could you give me the options you chose for partitioning and boot? I'm thinking about a UEFI boot with GPT partitions.For Linux, / (root) and /home on the SSD, and var on the HDD.For Windows, I don't know. Should I install the whole OS on the SSD, and give it access to a DATA partition on the HDD? I'm aware my post doesn't provide much information about my issues, but what I'm looking right now is a configuration that is known to be working on the X220, and on which I can focus my work. Also, the configuration should minimize the number of read and write on the SSD. Thank you 

Answer:Dual Boot on SSD + HDD: MBR/GPT? UEFI/LEGACY?

I'm not too used with uefi machines, but what I'm doing usually is to install grub at the start of the linux partition, not on the mbr (say  on /dev/sda3 not on /dev/sda) then I use easybcd (from windows) to add the linux partiton (and any other OS) to the standard win7/win vista bootloader.

I have disabled the secure boot option and enabled the Legacy boot option which allows me to boot from USB stick. However, UEFI takes precendence over Legacy boot and I don't want that. For a little school project that we are running we want to run the educational OS Sugar on Stick(on a USB stick) to run straight from the stick instead of kids pressing 3-4 different buttons to get to that.  In short, I want to change boot priority from UEFI first to Legacy. Let me know how to do it? Whether its possible or not? If not, then I don't need these 4 laptops that I ordered and I will return the laptops. Thanks a lot in advance. -Ritesh

Answer:Custom Boot Logo Windows 10 UEFI Boot Method? (Non-Legacy)

You can change the boot logo in UEFI mode by modifying the relevant ACPI table (BGRT) with an EFI application before booting. AFAIK, the only application for this is currently my own, HackBGRT. (Open-source and all, so I certainly hope this doesn't count as advertising.) Be sure to tell if you find any other choices.

Hi

Satellite C850-F0055 laptop

I am trying to figure out how to access the boot menu at power on.
I have tried f2 & f12, f2+fn & f12+fn, tried holding the keys, tapping the keys
holding for 1 second etc, I have tried all the f keys as well, tried esc, backspace
ctr+ del nothing works.
what happens when I boot up, within 1 second 'Toshiba Innovation' screen appears
and then proceeds to load Windows 8.1.
I can access BIOS/UEFI via charms-pc settings and navigate to UEFI and get in that
way but that won't help if I need safe mode.
My settings are:- ODD/USB/HDD, boot speed set to 'normal', Secure boot disabled
I have a dual boot system with Windows/Linux.
If I put a boot disk in and power up, the boot option is totally ignored but with the disk still in
and Windows loaded and I access UEFI via the above route, enter UEFI and exit again
immediately the disk bursts into life and loads the disk as is supposed to happen at start.

I have not sure where to go now so any help will be appreciated

Cheers Rozzer

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).

I did two things:

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.

Sometime in the fall I started getting Windows 10 update errors trying to install 1607 (the anniversary update I believe). After trying different fixes I just ignored it for a while hoping windows would come up with a fix. 6 months later and I'd like to finally resolved this issue once and for all.

Windows Update Failure

I found I can use msinfo32 from the cmd shell to see my BIOS Mode which indicates I'm in UEFI
So I'm not entirely sure what the problem is. I did some funky things when I first built and installed Windows on this computer about a year ago. I have a 3TB Hard Drive and a 500GB SSD. And I found out I wasn't able to use all 3TB without using a GPT. Found some guide online followed the steps and fixed that issue.

I think there was an issue after that where the 3TB hard drive had the Boot part on it, and I followed some other guide to get my SSD to be the boot drive. But I think what I did then has put something in a weird state thats causing the update issue above.

Heres the Partitions
And heres using diskpart
Looking at other peoples partitions when using UEFI and GPT they have some partitions I don't have. Like MSR, System, Recovery etc... but mine just has the one single Primary partition. Recommended UEFI-Based Disk-Partition Configurations What I also find weird is that my boot partition is Disk 1 instead of Disk 0. If I unplug the HDD and boot the computer, then the SSD becomes Drive 0 but the update still fails.

Unfortunately I'm in that place... Read more

My sister-in-law was installing a printer software and after it downloaded and rebooted it froze on blue screen with please wait. She left it that way for hours then finally powered down and restarted only to come to the same screen. I received it from there. I started by loading setup and doing a HDD scan everything looks good, but still please wait. Restored factory defaults and now it loads to boot device not found. Changed UEFI to Legacy and it loads windows only to come back to please wait. Tried f11 to recover but doesn't load recovery info. Tried using a repair disk from win7(still in legacy because UEFI wont load from dvd) that got me to system repair but could not self repair.

Hi all,
I currently own two latitudes; a dell Latitude E6540 and a recently picked up Latitude D630. Am I able to use UEFI on the D630, first of all, and for the E6540, how to switch boot modes? (I'm running Windows 10, though he came to me running 7). I tried simply toggling the setting in BIOS but after doing so, I'm greeted with the nice message of no boot device found (even when my technician friend messes with it, he gets the same thing). Suggestions would be excellent. Thanks.

Answer:How to successfully toggle a latitude's boot from Legacy to UEFI?

The D630 does not have UEFI - it's BIOS only.
To change from UEFI to legacy or vice versa, the hard drive needs to be repartitioned and Windows needs to be reinstalled.

Then Select 'Boot manager' to choose a new Boot Device or to Boot Recovery Media"Then it goes to the boot option menu and gives me a list of the two boot options:"EFI Network 0 for IPV4""EFI Network 0 for IPV6"with no option to select the HDD despite BIOS being able to detect it.I changed the boot mode to Legacy Support from UEFI, and this time on the boot option menu I got a choice to boot from the HDD or the ODD. When I chose to boot from the HDD I got another message saying "Check cable connection!" PXE-MOF: Exiting Intel PXE ROM."I tried to boot Ubuntu from a flash drive and from a CD, but I still got the same result as when I tried booting from the HDD.I think the problem is that my Laptop won't boot in legacy support, but when I use UEFI I only have the option of booting from the network.

hi MattQE,
 
Welcome to the Forums.
 
Just to verify, is the unit originally Windows 8 and this problem occured after you upgraded to Windows 8.1? Any changes that you made to the machine before the problem occured?
 
From the looks of it, this seems like a hardware failure but can you try the following:
1. Boot into the BIOS and set the following options (if applicable):
 
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.
 
 
Let me know how it goes.
