Preferred Solution: Why some people disable UEFI Boot Source in the UEFI BIOS?

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.)

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.

Platform:
Windows 10 Pro
GA-X79-UD5 rev 1.0
E5-2670
40GB DDR3 Quad
512 SSD
GTX 1060

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

Did a bit of online research and realize that two ways of fixing this
1. Change PCI setting to Legacy in BIOS/UEFI
2. Update to latest BIOS.

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

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

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

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

A few months ago I purchased a new Lenovo ThinkCentre M73 Small Form Factor desktop computer. It has Windows 7 Professional preinstalled.  I am thinking of updating to Windows 10. My M73 has a regular BIOS.  Can it be changed to UEFI, and would there be an advantage in doing so?Also, I am planning to install an SSD and move the OS to the SSD and use the HDD for extra storage. I think this would be a significant improvement to the system speed and faster boot up.  I have done it on older desktops I own.Thank you in advance to anyone with good advice.

Okay, I've been working on getting my 2nd PAvilion 20-b014 into a dual boot configuration for 3 days. I've scanned through tons of HP Support docs as well as Ubuntu support docs. I got Ubuntu loaded on a partition. I disabled Secure Boot and enabled Legacy Support. The problem is that UEFI is a major pain in the butt. I downloaded EasyBCD to manage the dual boot only to find out it won't work with UEFI. Everyone says "Turn it off" But when I did, then I got a black screen that said there were no boot files. And Windows Manager is ONLY in UEFI, not Legacy. At the same time, I cannot access my Linux distribution anywhere. It loaded successfully and there's even a boot drive for it, but I cannot see it listed anywhere or access it.  So I need to know how to get the Windows Manager into Legacy so I can turn UEFI off completely. Supposedly then EasyBCD will work and then I can get my dual boot going so I can actually use Linux. It's either that or delete the whole thing and use it as a hockey puck.

**** 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

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.

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.

Hello to the forum. Thanks for the welcome. And thanks for pointing me in this subforum.

I have a notebook toshiba satellite L850-1HU with UEFI

Default is win 8 os, recently upgraded to 8.1.

Now I need to win 7.

I have a professional license N sp1 x64 and then supports UEFI

Is possible to combine the systems in dual boot and both in UEFI mode?

I see from your guides that for installation the UEFI is necessary partition in a certain way.
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?

If I change hdd, and install win 7, when I put the old hdd, it works as before removing it?

Sorry for the confusion! I hope you manage to understand me and help!

A:Satellite L850 & Win 8 UEFi: How dual boot UEFI win 7 ?

If I change hdd, and install win 7, when I put the old hdd, it works as before removing it?



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.

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

I want to do a clean install of Windows 10 Home on my XPS 8700's boot drive. The existing install (done using the Microsoft Windows 10 Upgrade over top of Windows Home 8.1) is getting flaky so I decided to clean install it. Only problem is, the XPS 8700 UEFI bios prevents that from happening, seeing my Win 10 Home clean install DVD (or any bootable CD/DVD I've tried, such as that which comes with Norton Security) as some sort of security risk. The XPS does nothing, does not recognize the disc in the DVD/RW at all. So I can't boot off the Win 10 Home clean install disc and am stuck.
Does anyone know how to temporarily disable the function of Dell's XPS 8700 UEFI implementation so I can boot from the DVD/RW, as one would using a conventional BIOS?
Thanks in advance.

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?

A:UEFI/Secure Boot or not to UEFI/SB, that is the question..

Secure Boot does not affect the speed of your computer.

Windows 8/8.1/10 are compatible with the Secure Boot.

I don't know about Acronis True Image but Macrium Reflect is compatible with the Secure Boot.

It is a very important security feature.






Microsoft designed Secure Boot to protect the computer from low-level exploits and rootkits and bootloaders. A security process shared between the operating system and Unified Extensible Firmware Interface (UEFI, replacing the BIOS), Secure Boot requires all the applications that are running during the booting process to be pre-signed with valid digital certificates. This way, the system knows all the files being loaded before Windows 8 loads and gets to the login screen have not been tampered with.

Dear Friends,

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

Laptop: ASUS UX31A-DB71, latest BIOS: 218

Originally my laptop came with Windows 7 and when i looked at disk management my disks were formatted with UEFI schema. One of my friend gave me a UEFI bootable USB drive loaded with Windows 8. So, i thought why not give it a try. So, I created a backup of my OEM Windows 7 and saved the iso files in a seperate external HD (created twice just to be sure . Now, i decided to load the Windows 8. Booted into the BIOS and there is an option to select the USB drive along with the UEFI option for that USB drive. I selected the UEFI option but some reason it does not boot into UEFI. So i decided to select the standard USB install and this option let me install windows 8. In the process of installing i formatted the partitions and made a single partition and installed Windows 8 on it. I am guessing now the drive is not GPT but MBR. I also noticed that his installation USB disk had an option to select either 32bit or 64bit of Windows 8...I find this kind of odd. Would Microsoft create a same iso file with both versions? I am guessing he created the USB from a illegitimate source.

If your computer was running WIndows 10 without any issues prior to downloading the Anniversary update, then you would not have had to change any settings in the bios to install the update.The UEFI and Secure Boot settings are to enable booting with a USB or DVD to install Windows.
Disable Legacy Boot Mode and Enable UEFI
Start the computer and TAP the F2 key to enter the bios. Once in the bios Press F9 to Restore the bios to the Default Settings. F10 to save changes and exit. You could have a hardware problem.

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.

If not, restart the computer and press F2 to enter Setup (Bios) Here go to Boot Priority. Move the HDD up to First Boot Device. Also go to the Security tab, if Secure Boot is Enabled, using your Enter and Arrow key, Disable it or change it to Setup Mode.
If this doesn't boot the computer, then the install is corrupted. Try using the Microsoft tool for Windows 10

Hi There,

I just built a desktop with a sabertooth x79 motherboard, and am running Windows 8.1 pro 64-bit. When I click the UEFI BIOS Firmware live tile via the change PC settings>update and recovery>recovery>etc. my computer reboots normally to Windows and will not open BIOS. I have tried accessing it using the delete and f2 keys, but this does nothing either.

Any ideas? I am up to date in terms of my BIOS, and am definitely running UEFI and not legacy.

Thank you so much.

Dear Bleepers,
 
this is our strange situation:
My friend has a samsung laptop Ativ Book 2 (np270e4e) with windows 8.
After few problems when updating to 8.1 (it deleted the o.s and gived only a bsod saying that there is not any os installed), she decided to buy and install windows 7 so she disabled the uefi, setted the legacy mode and the boot priority first to the usb hdd (we have a bootable iso).
Parphaps every time we restat doesn't boot from the disk but showed the windows 8 bsod. Naturally the f4 for restore gives anoter bsod for not founding any partitions!
We discovered that it's not possible to boot from the disk, so we made a bootable usb driver with the official iso.
After that we picked up the hard disk and delete all partition from another pc and disabled all the boot driver but the usb hdd. After that it booted from the pen drive with official w7 iso.
The installation was completed in about 30 minutes. We started to install the drivers, chipset, intel storage but:
the next reboot it showed this message: all boot options are tried. press f4 key to recover with factory image using recovery or any other keys for next boot loop iteration and it was a continue loop and can't access the bios.
Strangely when the usb driver with the official w7 iso was inserted it said: "press any button for starting with usb driver"  and if we don't press anything windows started normally.
So we tried to install another time thinking it was a driver conflict but the second ti... Read more

A:All boot options are tried, no (uefi) Bios

Seems to be a common problem with Samsungs. See this thread and the post by François.  Can you access the boot menu by tapping F2 instead of holding it down? See if you can access the computer with Fatdog64. You will need to burn the iso file or use Rufus to create a bootable USB. If the USB does not boot then use GPT as a partition scheme in Rufus. 
 
According to here F2 is the boot menu for a Ativ Book 2, 8, 9 but F10 is the UEFI access key. Try tapping F10 at boot.

I just bought sony vaio S Series, with original Win 7 home basic 64 bit. But, many of my device such as printers, network wifi and etc not support for win 7 64 bit. Now, I want to install win 7 32-bit on my laptop. But, My CD Win 7 bootable won't boot at my laptop. After i check bios, i found something strange on boot menu orders, if the boot in "Legacy" mode, that laptop will boot from my cd. 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

A: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.

I don't have the option in windows to boot back into the UEFI setup. In my motherboard bios setup there is an option which allows for the selection of UEFI, Legacy and UEFI or Legacy, When I change this to UEFI my pc wont' boot and the error message is that no UEFI partition was found.

I think it may have been deleted when I installed Windows 8.1 initially because i had to convert from MBR to GPT. Or so i read on one of the forums.

Is it possible to restore my UEFI partition so that I can use windows to enter the bios setup. I've had the boot on ultra fast and it took me a week to get into the bios without using the delete key. I had to use Gigabyte utilities which include drivers that crash windows. So i want to remove them again ASAP.

Any help appreciated.

A:UEFI option instead of Bios boot

Well to get back into UEFI mode you will have to reinstall in UEFI mode there is no other way, Sounds like some how your OS got converted to MBR so It may not boot either MBR or UEFI but you can't convert back to UEFI you have to Reinstall. If you have data on that disk you need to recover you can pull the drive and hook it up USB to another computer and recover your Data.

Hello together, i have a problem with our System X3650 M4 Server, Machinetype Model: 5462G2G. I downloaded an imm and an uefi update file from the lenovo website.First i updated imm through the imm2 website remotly.Update did go as planned, i restarted th imm2 and after about 5 minutes the new imm2 was working an accessible,Then i tried to update the uefi bios from version 1.01 to 2.31 , also via the IMM2 -> Servermangement -> Server Firmware -> Firmware upgrade option.I Uploaded the new file lnvgy_fw_uefi_tce128i-2.31_anyos_32-64.upd, then started the upgrade process. It went through fine, and after the sucess information i was prompted to restart the OS.After 30 minutes, the server was still in System State = running in uefi mode.When i checked back to the server management -> Server firmware rab, it said UEFI Primary, Status pending, Version 2.31.Then i "powered off" the server, and restarted it 5 minutes later. All status boxes are green, but system status is still in "system running in UEFI " Mode, it wont start with the OS (VMware) Does anyone have an idea how to fix the problem. The Server also has a secondary bank with the old bios version  1.01 , how can i switch back to this backup BIOS? Many thanks in advance, i am getting a bit desperate here. The server should be operational tomorrow morning again.

Hi guys, I'm trying to properly dual-boot Windows 10 Edu 64bit and Kubuntu 16.10 64bit. 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.

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

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

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

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.

A: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.

There is a utility called fast boot, is that on your disk?
If not you can get it at the MSI website. That will allow you to disable fast boot and enter the BIOS.

Will it be possible to boot Windows 8 from a GPT partition using BIOS (not UEFI)? I'll be using the 64bit version.

Technically, I know it's possible as I'm doing it with FreeBSD, many Linux distros etc. Using hybrid MBR/GPT, I've read others have Win7 booting off GPT partitons as all. I'd rather not go that route.

I am pretty sure you can't do that with Windows - not unless MS have changed something without announcing it.

The System Board has an update for it.
Boot to Windows 10 UEFI does not enable the USB mouse and keyboard, and I do not have a PS2 combo to attempt, although I am not sure that will work either, depending on consensus.
Might this be Legacy BIOS/UEFI mode related?
Boot partition has prefix part. for UEFI (100MB) and is Healthy.
Boot disk is Basic GPT off a Samsung 830 120GB SSD.

Hi all,

I have just recently installed Windows 7 on the Plextor M6 Pro 128GB SSD. Everything went fine for the first few boots, and Windows will not boot up after that. The computer automatically goes into UEFI BIOS as if there is no Windows installed on any of the hard disks.

I removed the SSD and inserted it into the external enclosure and hook it up to my laptop via USB. Windows (on my laptop) did not show any removable media under My Computer. Upon firing up Disk Management, the following screenshot (Screen1.jpg) can be seen.

I humbly seek for advices of anyone out there who might be able to help me regarding this issue. I have previously successfully installed Windows 7 on all my older PC/Laptops. But this is the first time I have installed it on an SSD. My previous installation on HDD works well without issue (used it for 6 months before I reinstalled it onto the SSD). I ran into this issue twice within the same day (I reformatted and reinstalled Windows after my first encouter).

I will post whatever details required to solve the above issue. Also, any explanation and information regarding the issue as well as how to prevent it from coming back would be very useful.

Many thanks in advance!!

A:HELP!! Windows 7 on SSD failed to boot, goes into UEFI BIOS.

Hi there

In all cases ensure LEGACY BOOT is enabled if that option exists in BIOS.

1) First ensure PROTECTED BOOT is DISABLED -- this doesn't mean turning off UEFI.
2) Ensure the SSD is formatted to GPT and NOT MBR
3) Ensure your W7 install media will handle UEFI boot and install.

If you Don't want to use UEFI boot

1) Disable UEFI in BIOS.
2) Format SSD as MBR
3) Install W7 - default mode will be non UEFI.

Cheers
jimbo

Asus G73sw Laptop that I have used every day for the last 2 years.

So, I got the message: "Reboot and Select Proper Boot Device, press any key" so I tried another working HDD that has windows 7 on it; same message. I took apart the computer and checked the connections and cables. One time, during the constant restarts with other HDDs, I got the message "A Disk Read Error Occured." When I entered the BIOS menu, It recognized the HDD. Also, on the Easy Flash, I could see that HDD and its files.

Finally was able to load windows with UEFI mode. I am unaware what this is, but I assume it will work for now?? I have made no updates to windows 7, installed no drivers or programs recently, and am unsure why BIOS won't load any of my HDDs to windows, when BIOS clearly sees it.

Can anyone help me with this issue?

Thanks

OK, you cannot take a hd with windows already installed and put it in another system then expect it to boot. Not going to happen unless the two systems have very similar or identical hardware.
Finally was able to load windows with UEFI mode.Click to expand...

This allows windows boot mgr to take over the boot process. This is not the only difference; there are many. UEFI uses GPT table, can address larger hd, and a lot more. Here is an article that explains uefi in more depth;
