Bios disable legacy, enable UEFI, change boot order

Question: Bios disable legacy, enable UEFI, change boot order

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

Preferred Solution: Bios disable legacy, enable UEFI, change boot order

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.)

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 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

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. At some point I got into the menu for this, but must of the times I just get straight to the BIOS. 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
I can't find a way here to post photos from my iphone (and can't use the computer), but here is what it says on the startup screen of the BIOS. The only options I have from here is either "Delete RAID volume" or "Reset Disks to Non-RAID" (none of which I know what it means)
Physical devices:
ID. Device model. TYPE/STATUS(Vol Id)
0. PLEXTOR PX-256M6. Member Disk (0)
1. PLEXTOR PX-256M6. Error Occurred (0)
4. HGST HTS721010A9. Non-RAID Disk
I know I fucked up and should have done more research before tweaking with this, but the damage is done so I greatly appreciate any help

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.

I was running Windows 10 Creator on an MBR system using an MSI H61M-E23 (version 2) motherboard.

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.

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.

When I access my UEFI during startup, the Boot Priority section is either empty or shows unrelated drives attached. I can select the drive from which to boot by clicking on the Boot Menu, then clicking on the drive desired.

I purchased a new Intel SSD and installed it as the "C" and "D" drives and was happily booting from that SSD until I added new HDDs to my system. I now have four HDDs plus the SSD. One of those HDDs still contains the original Root C bootup and Windows 8 system on it. I frequently now find the system, reason unknown, may choose to boot from the HDD rather than the SSD.

I cannot find the method for directing the UEFI bootup menu/priority steps... my goal is to have the computer boot from the SSD, which if it were to fail, then would secondarily boot from the HDD original Root C.

The computer arbitrarily changes the SSD from drive designation "C:" to "J:" and the HDD to "C:"... how to specify the SSD as the "C:" unless it fails or is removed?

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

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.

The problem is that on startup it's impossible to start GRUB, Windows is loaded automatically. Is there a way to change UEFI boot order? I tried several methods but Windows always overrides my changes; I managed to load GRUB only once by renaming the Windows OS Loader path to the GRUB one, but after I booted to Windows once again, it overrode my settings creating a new Windows OS Loader entry. These are the methods I've already tried: Renaming the path as I said up here through bcdeditUsing EasyUEFI to change boot orderUsing efibootmgr in KubuntuUsing boot-repair in KubuntuUpdating GRUB in Kubuntu While on my desktop I have a BIOS setting that lets me change UEFI boot partition, I don't have anything similar on this laptop. Let me know, thanks.

Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)
My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD
So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.
I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.
So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

Answer:Changing boot order when BIOS is set to UEFI

You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

You may have to turn off Fast Boot if set.

Hi, all.
 
As the title says, I have Windose 8 on a 64-bit Samsung laptop and I need to change the boot order to test if a bootable Linux CD works, which I intend to use if it does (or download it again and make a new one and use that), but I can't change the boot order from the OS to the DVD ROM drive.
 
Another thread online said something to do with Legacy but I don't know what that is nor how to disable it to see if I can enable and select booting from the DVD ROM drive.
 
Please help. Thanks.

Answer:Unable to Change Boot Order in Samsung Laptop UEFI

I don't know what model the Samsung is but in UEFI settings make sure SecureBoot is disabled. If there is a setting for FastBoot or QuickBoot then disable it also.
 
If there is a Mode listed set it to UEFI/Legacy. 
 
Reboot and enter UEFI. Can you see change your boot device priority?

On a Samsung tapping Esc at boot may give you a boot menu that will let you select a boot device but SecureBoot should still be disabled.

I have an Ideapad Z585. My hard drive is having problems (won't boot), so I want to boot from a DVD or USB. Problem is, when I change the boot order in the BIOS (UEFI) to put the optical drive ahead of the hard disk, that setting won't save (although others do). When I exit the BIOS and look again, the boot order setting has returned to the original (hard drive first) setting.  **bleep**?? This means that if my hard drive is present, it will ALWAYS be used to boot from, which of course ALWAYS fails. There is no way to fix the hard disk because I can't boot anything else. This is a serious bug in the BIOS / UEFI.

I heard that before I install Windows to the new SSD, I should change settings in BIOS to AHCI concerning my hard drive. My Problem now is that I can't find it in BIOS.

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.

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: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.

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,

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...

My short answer here to this, is that it sounds like your BIOS needs a swift kick in the pants! Maybe the BIOS just needs a jump start, maybe to get things back on track. This is just a real quick little fix, if it works.

1. Remove the computer from power, unplug the power cord from the power supply.

2. Take the side panel off your computer case, exposing the guts of the machine.

3. Look for the motherboard, then look for a small shiny chrome colored battery.

4. Remove that chrome colored battery off the motherboard.

5. With the battery removed, take your hand and press the (power) button on the front of the case.

6. Keep that button depressed and or pushed for approx. 30 to 40 seconds, while your computer BIOS is drained of it's power and hopefully it's current setting.

7. Let off the (power) button, replace the chrome battery back onto the motherboard, replace the side panel of the case and reconnect the computer power cord to the back of the power supply.

Now turn on your computer and see if that helped take care of some things! Again, this is just one of those quick fixes that may or may not always work.

Hope this helps.

Hey guys,

My PC is running Windows 7. In the past I never had an issue running memtest from my CD. I would put the CD into the PC, restart the PC, press a certain key (I think) and Memtest would load.

Unfortunately I forgot what key I used to press and Memtest won't load, it goes straight to the Windows Startup Screen and the Desktop loads.

I went into Bios and I saw that CD/DVD was not #1 in the boot order which is strange because I used to run memtest many times on this PC and I never changed the Boot order.

I tried changing the boot order by hitting the + key but the key won't do anything. Is there some other key that I need to press in order to get + or - working?

also I see two CD/DVD's in the boot order of the Bios, I guess it's because I have two CD/DVD drives? Which one do I make #1? The Memtest disc is in the bottom CD/DVD drive.

Any help is much appreciated
 

Answer:Can't change boot order in Bios to run Memtest

Usually Memtest starts automatically without any key presses if your CD/DVD drive is 1st device.

What brand and model motherboard are you using? Usually it tells you at the bottom of the screen in the BIOS what keys you have to press to navigate through the menus. The manual probably explains it in great detail, but I know, who reads those things?

We aren't going to be able to tell you which drive is which, you will just have to try trial and error with at most 2 restarts.

My dv6 has a shattered LCD screen, but works otherwise.  I'd like to get into the BIOS and change the boot order so that I can boot from CD/DVD or USB. When the computer boots and I press F10, computer goes into the BIOS setup but I cannot read the screen and navigate the menus. Any suggestions? If someone can see their BIOS screen, could you tell me which keys to press, in order, to reset the boot order and/or to set CD/DVD and USB to boot before HDD? Many thanks in advance,-Craig-

Hi there, I hope this is the right forum for this question.

My son has an i7 custom build computer and the previous owner gummed the computer up good with malware etc. The current setup is Windows 8, but our goal is to install a fresh copy of windows 7 Professional 64-bit which we have purchased "intended for distribution with a refurbished PC".

This is a bit of a project for us, so we are taking our time with it, and hopefully learning something along the way.

We are trying to wipe the HDD completely on the machine, but we are unable to run DBAN to do so, because every time we restart the machine it keeps booting up in Windows instead of DBAN. I have gone into BIOS and changed the order of the BOOT to read from the CD-ROM followed by the USB before the C Drive (I have copies of DBAN on both USB drive and CD-ROM). But it is still not booting. Not sure what to do???

Cheers,

Sean

Answer:can't boot DBAN trying to change boot order in BIOS not working

It is possible you have not created a bootable CD/USB. Use Rufus for example. https://rufus.akeo.ie/

Also provide motherboard make/model please.

I am trying to delete all the files from an old HP (XH545) laptop running XP. Its screen doesn't work, so I have it attached to a remote monitor. I have both a bootable floppy and bootable cd which have [email protected] Kill Disk. My intention is to boot one or the other and erase everything on the hard drive.

Problem: I am unable to get into my BIOS to change the boot order. Since I have to do a Fn-F5 to switch over to the monitor, I am unable to get there in time to see when to hit F2 to edit my BIOS. I have been trying for several hours to "guess" when to hit it, still with no success. I'm not even sure I would be able to see the BIOS screen anyway - maybe you have to get past that for Fn-F5 to swap out to the monitor.

If I let the system boot normally, I can swap over in time to see it loading Windows XP.

Question 1: Is there any way to change the boot order from within Windows (or from DOS prompts)?

Question 2: Lacking a positive answer to #1, is there any other way to delete all the files from the hard drive so I can dispose of the laptop?

Thanks!

I have an Aspire M5 that is not bootable.  I ordered and received recovery discs from Acer.  When I boot using UEFI mode, I get the following error message... "Please boot this Recover Disc uusing legacy BIOS mode."  When I boot using legacy BIOS mode, I get this error message... "Restore Fail: This recovery system can only be used on "UEFI" mode.  Please press "OK" to restart the system immediately."  I attached screen shots of both.  My guess is something else is wrong that a recovery disc can't fix.  Any thoughts or suggestions on how to proceed?  Thanks!

you need to completly wipe your HDD before restoring your PC. are you able to reach windows command prompt? (try to press shift+F10 keys at that screen)if so, try this:typediskpartthen on diskpart typelist disktake note of the correct disk ID to erasetypeselect disk x(x is the ID of your HDD to erase)typecleantype exit if not, you can create a bootable USB or CD (boot under legacy) with gparted that will jelp you erase your HDD:http://gparted.org/livecd.php

it will help members to help you if you could post which operating system is insatlled on your Z580 and also which keys you have been pressing in order to enter BIOS.
 
Have you been pressing the keys during a warm or a cold start?  There are some other very similar posts on the boards, the following seems to contain some good tips which you may / may not have already tried.

I was dual booting Windows 8.1 Update and Ubnutu 14.04 From the windows disk manager I deleted all Ubuntu partitions and rebooted my notebook. I was immediatlly present with the grub rescue promt. Normally this is a quick and easy fix, by booting a windows USB/CD and repairing the windows MBR.  My problem is I can't access the bios or the boot menu to change the boot order. Nothing I've tried has let me get into the bios to set my USB stick as the first boot option.  Using the small recovery key button on the side of the notebook which normally boots the notebook to the screen where you can choose which drive to boot does the same as the power button. There is no bios flash screen or abililty to press any keys before getting to the grub screen.  I've drained the battery and left over night hoping this would reset the state it seems to be stuck in but that also did nothing.  Here is a short video showing what happens when I boot the notebook http://youtu.be/2FpC2Deuawk

Hello,
I have a Lenovo laptop that is about 4 years old. It was working fine earlier today but when I picked it up to turn it on it was powered down and the message came up saying BOOTMGR is missing Press Ctrl+Alt+Del to restart. I tried to restart and enter the bios to change the boot order so I could boot from my windows 7 usb to repair the problem with the command prompt but it would not let me into the BIOS. I tried burning a windows 7 Disc to try that but again it won't boot from the cd/dvd either. I know how to fix the problem but I cannot access the bios to change the settings. What could that problem be caused by? Is the mother board gone? I have seen other posts similar to this but everyone seems to pay attention to the windows part and not answer why they can't access the BIOS. I have tried all the keys, F2, F8, F12, F10, ESC, Del. Normally the F2 key works for entering the bios and the F12 is for changing the boot order on my machine. Please help with this BIOS problem and ignore the Windows BOOTMGR problem.

Thank you

We are now migrating from Windows 7 to Windows 10.With windows 7 we were running legacy BIOS. Now with Windows 10 it is UEFI and Secure Boot on all machines before deployment of operating system. I have configured the BIOS settings exactly as i wanted on one machine. (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!

After trying again I got this error:Restore Fail: This recovery system can only be used on "UEFI" mode.

Answer:Recovery CD fails. UEFI/ legacy BIOS problem

if you still have the Ubuntu installation CD, boot from that and choose to try it Live, instead of installing, once booted run disk manager and completly wipe your HDD, must be with unallocated raw space.Then try again with the recovery cd.If it gives errors again, you must check if the HDD has GPT boot record instead of MBR.

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).
Any other suggestions?  I can use Windows but Win 10 doesn't have full functionality without UEFI / Secure Boot enabled. And I'd hate not being able to access the BIOS or boot menu forever.  I hope some Dell expert can help me get in to th... Read more

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 & Brink's Windows 10 - Clean Install tutorial 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?

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
