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.)

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!

**** You need to enable Legacy MBR by Enabling Launch CSM in the EFI Setup ****

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....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

I have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.
I've tried several things (turning off Secure boot, changing from UEFI to legacy bios--it won't boot at all that way) , but I can't get that second disk t... Read more

Wanted to try the UEFI so I deleted my legacy BIOS/MBR installation of Win 8.

I followed the steps here:
UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with[2]=Installation%20and%20Setup

Got Win 8 to install successfully in in the UEFI/GPT way.
But after restart on installation done, the PC cannot boot into Win 8 and I always get the light blue screen with a "Recovery" title stating that the PC couldn't be started properly and an error code 0xc00000001.

Played with the BIOS setting (CSM, Secure Boot etc), switched to onboard graphics, reinstalled a few times the UEFI way.
Also tried the automatic repair but to no avail.
The UEFI installation is always successful but I always cannot boot to Windows.
What different is that the installer always partition the drive to 4 partitions (Recovery, ESP, MSR, OS) instead of 3 in the tutorial.

After hours of trying to get it to boot UEFI Windows 8, I gave up and went back to install via legacy BIOS/MBR.
And here I am posting this in Windows 8 (legacy BIOS/MBR).

If possible I would like to get UEFI working, are there any small details I missed?
I'm using the ASUS P8H77-M Pro motherboard with the latest BIOS.

Hi all!
I have Alienware Aurora R4 machine with three hard drives:

(Local Disk)C: - (Windows 7) the “original” one that I bought with the computer.
(OS)D: - (Windows 10 with all updates) the one I’ve added after the “original” started to show signs of degradation.
(STORE)F: - (no OS) the one I use just to store stuff.
I’ve had dual boot and everything was hunky-dory until last week the C drive have finally kicked the bucket.
First the computer refused to shut down until I forced it. And next morning it took more than TWO hours to boot. When I finally got to the window explorer the C drive was still there but I couldn’t access or do anything to it.
In the old times I could just remove it and set boot priorities in BIOS to boot from drive D. But if I actually remove the dead drive now, the computer says that it has nothing to boot from. 
It appears that with UEFI mode enabled

I don’t see the actual drives in the BIOS (It only shows general source types, like Hard Drive, CD/DVD, etc.) and therefore cannot boot from a particular internal drive.
I cannot assign Active Partition
I cannot remove the dead C drive

So, what am I supposed to do? Please, HELP!

Hey all,

I just got a new HP ENVY dv7t-7200 CTO Quad that came pre-loaded with Windows 8. I wanted to install Windows 7 so I enabled "Legacy Support" in the BIOS which disabled UEFI mode. Everything went fine from there. I ultimately decided to go back to Windows 8.

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

Hello all,

This is my problem:

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

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


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

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

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

Hello, I have a problem with booting Windows 10 X64,  after installation with GPT, on a  HP 8200 Desktop, with 2 HDD in Raid 1.I have updated the firmware to the latest version v 02.29 . Until the update, Windows 10 x64 was installed in UEFI mode and worked ok. I tried to update the firmaware to the last version because i was unable to use WOL for starting up the PC.After disabling fast boot in windows and made different changes in BIOS, WOL turned on the PC but after the boot screen Windows doesn't loads ( a blinking cursor remains in left up corner and doesn't do anyhing). If i try to turn on the PC from the button Windows loads normaly. I recreated the RAID, and reinstall Windows with GPT. After the setup finishes, and the computer reboots, i have the problem that i haved when starting from WOL (a blinking cursor remains in left up corner and doesn't do anyhing). I'ved tried to reinstall Windows changing different settings in BIOS, but it still doesn't boot. I boot from Hiren with the miniXP and i saw the partitons and the content of C:\ and all seems to be ok.I installed Windows in MBR, and with MBR is working fine.

Hello everyone,

I made a post about this over on the Tom's Hardware forum also, but I think this might be a better place to ask.

I'm trying to install Windows 7 from a USB stick onto a small partition (100GB) of a 4TB HDD for an HTPC. When I first tried to create a partition during the windows install, it made the 100GB partition I wanted, but it also split the remaining HDD space into 2 different drives. After some reading, It seemed like the problem was that the drive needed to be formatted/partitioned in the GPT style rather than MBR (in order for windows to accurately see the full 4TB drive).

So, I created a boot disk with the program Parted Magic, formatted the whole drive with the GPT format, and created my 100GB partition in NTFS. Now when I try to install Windows 7 on the partition, it says, "Windows cannot be installed to this disk. The selected disk is of the GPT partition style." And this is essentially where I'm stuck...

I've tried updating my UEFI firmware, and playing with various settings (turning safe boot off/on, changing legacy support options, etc...) but nothing seems to work and/or I just create new issues.

At this point, I'm in way over my head. Does anyone have any idea how I can fix my issue? Any help will be greatly appreciated!

So I've searched, and I've tested, and now I'm about to turn my laptop into a frisbee and never buy a Samsung PC again. In short, I bought an ATIV 7 whose previous owner had downgraded to Win7. I wanted to put Win 8 on and I have a volume license as well as the OEM key so I burned the ISO (actually 2 different ones) using every method I could find (ImgBurn, Rufus, Iso2Disc, Win7 Download tool, etc.) It became clear that the USB needed to be formatted FAT32 with GPT filesystem, however in UEFI mode it shows the USB but won't allow me to select it - it just flashes. If I set it back to CSM and UEFI I can make a USB boot, but even if I use diskpart to clean the drive and convert to GPT it will fail to install because it detects I didn't boot in UEFI mode.

Here's the deal. When I'd installed it earlier this week in CSM and MBR mode, and then converted to UEFI it worked fine. So....I tested several recovery programs we use at work to make sure they'd restore it okay via bootable media. Paragon, Aomei, Macrium, Lazesoft - all boot media failed. ONLY True Image 2014 DOES ACTUALLY BOOT in UEFI mode on my laptop. The only thing I can figure is that the way WinPE 5 or 5.1 (whatever it uses) is set up on it agrees with my laptop. So what I was wondering is if one of the geniuses here has any idea how I can modify the Acronis recovery media or create similar WinPE media that might actually boot on my laptop.

THanks for any help!!!

This is somewhat of a follow on to my earlier post dealing with migrating the OS to an SSD.  After havinig cloned the OS from the 2TB HDD, I wanted to boot from the SSD.  In the old days I would have gone to BIOS and from there selected boot priority of the various devices.  In this instance, I encountered UEFI and could not figure out how to change boot priority.  I saw options for legacy boot, some messages about disabling secure boot, and I was afraid to touch either.   So....I just swapped the disk cables and booted from the SSD.  
Still, I have the question, how can I change the boot priority?  Is there some Dell manual that gives a good explanation of the UEFI interface for me to study?

I would like to boot from UEFI (not bios) using a hard drive on our HP8300 small form factor boxes.  We need to boot from UEFI, because we want Windows 8 bit locker to interact directly with the hardware encryption of our Samsung SED SSDs (840 EVO). No problem loading windows 7 via bios on the Samsung SSD hard drive using the Windows install disk and booting from the CD drive as a legacy (bios) boot source.  This boots the machine using bios- and it recognizes the SSD as a legacy Hard Drive (SATA). BUT-- if I boot from the windows install disk from the UEFI prompt for the CD drive, Windows sees the Samsung SSD but says it can't install to it and can't boot from it.  Also, I notice that there are no hard drive boot sources listed in the HP Setup utility-- just USB hard drive, USB CD, and ATAPI CD.  Are the integrated SATA controllers NOT UEFI boot sources? The Samsung SSD was initially configured as a GPT device-- Windows 7 install (from a UEFI boot) still said it could not install windows to the SSD. Any white papers about HP UEFI?  Anyone know details?

HiI am experiencing pretty much the same problem. disconnected internal hdd and connected new SSD with gpt formatted image on it, go into bios and it shows the hdd as a legacy boot device and not a uefi boot device.  obviously trying to boot the gpt drive in legacy mode fails, but how do i get the bios to see and use uefi to boot the drive? if anyone can help it would be greatly appreciated.

Hi

Here is my situation:

I have upgraded a few days ago my daughter's PC from Windows 7 home premium to Windows 10 Home. The upgrade (a clean install) was done on a brand new SSD (Samsung 860 Evo 250gb). After the upgrade, I loaded several programs and created an image of my C: drive with Macrium reflect v7.2 free.

When I installed the Samsung Magician software I realized that AHCI mode was not activated. So I went into the UEFI and turned AHCI mode on. I saved and rebooted the PC. On reboot what I got was a blue screen of death (BSOD). In the process, I lost my Boot manager and had a hard time reboting. Now, everything is screwed up. Sometimes the PC boots and sometimes it does not. It is a mess. It is not reliable at all. When it boots though, everything works normally. Every time, I just do not know if I will be able to reboot or not.

I did not know that I should have enabled the AHCI mode in the BIOS (or UEFI if you prefer) BEFORE installing Windows 10.

To solve the problem, I am thinking of running a restore with Macrium Reflect as I have an image of the boot drive dated the day PRIOR to the day I changed the AHCI mode in the UEFI. BEFORE I restore, I want to change the UEFI setting of AHCI mode to ON.

My question is this:

Question 1
If I do just that, will it save my butt ? I mean not have to re-install everything.

Question 2
Will windows install the necessary drivers for the AHCI mode (after the image is restored) or will it turn AHCI mode back to IDE... Read more

I am trying to install Windows 7 Home Premium to my UEFI-based notebook. This notebook does not have a DVD drive though, so the only way for me to install OS's is via SD Card or USB Flash Drives.
 
I know how to start the UEFI installer because I can do it on my other laptop that has a DVD drive. I also was able to try and start the Windows 7 installer via UEFI on my DVD-less laptop, but it failed to boot after I pressed any key.
 
Is it at all possible to install Windows 7 in UEFI mode without a DVD?

I figured it out last night. I found a certain post in InsanelyMac forms that helped.

"Best method would be to use a 4GB FAT32 (not NTFS) formatted USB pen-drive. Extract the ISO or copy the DVD contents to the
pendrive, and copy the bootmgfw.efi file to /EFI/Boot/bootx64.efi . Go to http://www.insanelymac.com/forum/lofiversi...dex.php/t186440for info related to Windows
UEFI-GPT booting."
 
I moved the Boot folder from the EFI folder so that it looked like EFI\boot\ instead of EFI\microsoft\boot, then I threw the
renamed bootmgfw.efi in the boot folder. Worked fine.

I want to install Windows 7 to a UEFI-compatible netbook that only has a SD Card slot and a single USB Port (the netbook I'm refering to is the CR-48 if anyone is curious)

I know this computer supports UEFI (I was able to start the Fedora 14 EFI and Win7 x64 EFI installers) but my assumption is that EFI-based OS installs require you to have the disc inserted (both installers failed to actually load)

Anyone have an idea on a solution for this other then to buy a External DVD drive?

Hello,

I have just purchased a Dell Inspiron 17R Special Edition 7720. It came with a preinstalled Windows 8 (so 64-bit and mandatory UEFI boot). I want to use Linux (more specifically, Archlinux) for work and Windows for games, so dual boot is needed.
I almost completed the Linux installation except for the bootloader: I need to boot Linux from UEFI and didn't manage to do it so far. Here is what I did after I received the PC:

disabled Secure Boot;
updated BIOS to version A12 (maybe I shouldn't have...);
resized the main Windows partition and created a few partitions for Linux;
switched to legacy boot mode and managed to boot a MBR-bootable Archlinux installation USB drive;
installed most of the system
switched back to UEFI boot mode, Secure Boot off.

At this time I needed to boot the kernel from UEFI for the bootloader installation program to have mandatory access to the EFI environment variables. So I created an UEFI-bootable Archlinux installation USB drive (with a FAT partition) but so far I couldn't manage to successfully boot this drive from UEFI instead of Windows 8.
I think I really tried every single combination, such as:

different USB ports;
different boot entries created with F2 boot setup, with different parameters;
different orders for the boot entries;
hit my boot entries directly within F12 boot menu.

No matter what, in UEFI mode the system always boots the Windows partition.
Also, I could not find any relevant manual or s... Read more

Try going into Advanced Start-up Options.   Hold Shift key down while doing a RESTART while in Win 8.  This will get you to a page that will have an option called "Other Devices" (going by memory).    Choose it and you will have all the device options like USB. Give it a try first and I am sure there is a simpler way to boot Linus directly later.

Hi all,

So I got a new laptop its a Lenovo Y700-15ISK, UEFI Bios. I am trying to get the machine to dual boot Windows 7 and Windows 10. I installed Windows 10 first, no problem. Windows 7x64 is just not working.

My windows 10 was a fresh install, slipstreamed updates and drivers from Lenovo using NTLite.

Windows 7, slipstreamed all Lenovo Windows 7x64 drivers, also windows updates (sp2). Windows seems to install fine but when it reboots after the install and boot picks Windows 7 from the Windows Boot Manager, I get a blue screen! 0x0000007e. I installed the USB 3 drivers via NTLite in booth the install.wim and boot.wim. I don't have an issue with is asking for drivers at the Windows 7 install.

After installing Windows 10, I made these changes to the bios.

Boot mode: Legacy Support
Boot Priority: Legacy First
Turned off OS Optimized defaults

Installed Windows 7x64 from usb stick, install seems to work but when it reboots,
BSOD BLUE SCREEN! Same error 0x0000007e
Also unable to boot into windows 7 using safe mode. I get as far as:
C:/Windows/System32/drivers/disk.sys
then it BSOD's

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.

Nothing about the DVD drive or USB devices...

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. Where can it be found and maybe changed? Is it really needed to change BIOS mode? What are my alternate choices?

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.

What should I do if I want to leave intact the UEFI partition of win 8 (5 partition)? I just make only space for win7(1 partition) that will use the same 4 partition UEFI of win 8 or i make other 5 partition???
And which of the two systems will handle the boot? I can decide I?

and the warranty? restores factory work?

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:

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.

Greetings!
I am planning in the near future to buy a Dell XPS 8910 Special Edition.  I hope shortly after purchase to install a Western Digital Black Series 2-TB hard drive.  This new drive would be used as a storage drive for extra data.  It would NOT replace the original 2-TB drive installed in the system.
From checking the service manual online, I understand how to physically mount the drive, connect the nearby power cable then use my own SATA cable to connect the drive to the motherboard.  I also understand how to use Device Manager in Windows 10 to add/format the new drive.
From other posts I've read here, I must ask: Will I need to enter the setup mode(BIOS/UEFI) at the start of bootup to set the SATA port to detect the new drive, or will the SATA ports automatically detect the new drive without requiring my going into setup mode? 
Thanks in advance to any who can answer my question.  I'm looking forward to getting my new system soon!

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

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

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

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

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

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

So, anyone really think Secure Boot is worth it?

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