Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Q: Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

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.

Preferred Solution: Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Boot UEFI from wake on lan, or convert UEFI MBR to legacy.

Back up your files, unplug all other HD's and peripherals,

Boot into BIOS setup to enable Legacy BIOS. Next check BIOS Boot order for an EFI Boot Disk: remove it, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here.

At first installer screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Windows 7 target HD #)
CLEAN
CONVERT MBR
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

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

My system has several drives, two of which are 4TB drives. The two 4Gb drives are using GPT partition schemes. However, I'm booting off of a 240GB SSD which is using a MBR scheme.

When I installed my current motherboard, I did a fresh install of Windows 7. I didn't know much about UEFI, except that I hate it. Now I discover that there is an option to boot in legacy mode. I know in linux I can convert an existing system from UEFI to legacy mode by changing the EFI partition.

My question is, can I convert an existing Windows 7 install FROM UEFI TO legacy mode? If so, how?

If your PC or laptop supports UEFI and legacy mode then the following tips may help you. Legacy enabled:If the bios setting is legacy enabled then hard drives and USB devices will normally boot.  If you are using two independent hard drives that are not connected by boot manager then the UEFI boot hard drive will always boot first before the legacy hard drive unless the bios allows you to change the boot priority. Legacy disabled (UEFI mode):If the bios setting is legacy disabled then only UEFI devices will boot.  You may run into no hard drive selection menu, no boot option menu or Boot Device not Found followed by a message Hard Disk (3f0). USB flash drives boot considerations:If you wish to boot up a USB flash device using Windows 7 repair, Windows 8 repair, Windows 7 or Windows 8 installation media then be sure to create the flash drive formatted as FAT32.  You may notice a bootable flash drive showing twice in the boot menu, one marked UEFI and one not marked UEFI.  Both will boot up. The popular MS Windows 7 USB WIndows installation media creation tool will create a NTFS flash drive using a Windows 7/8 iso file in NTFS format which is not bootable in UEFI mode. It works fine in legacy mode.  To get around the NTFS issue, create the flash drive in NTFS then copy the contents to your hard drive, quick format the flash drive to FAT32 and then copy back the contents back to the hard dr...

Hi, My comany is purchasing HP EliteDesk 800 G2, some comes with HDD and some with SSD.We deploy Windows 7 x64 using SCCM using legacy boot. On a machine with HDD installed I can configure the boot options to use legacy boot, but when I replace the disk to a SSD drive the only boot option for this drive is UEFI.That causes the deployment to fail because the drive need to be partitioned as GPT.On the other hand, if I disable legacy boot, PXE boot to UEFI and partition the disk as GPT, after the image deployment the disk is unable to boot with 0xc000000d error (I imagine the cause is Windows 7 support becuase it does work on Windows 8.1). Bottom line, I can install Windows 7 on a HP EliteDesk 800 G2 only if legacy boot is enabled and I partition the disk as UEFI.Is there any way of forcing the SSD to boot as legacy and not UEFI?Is this issue caused by the workstation or is it enforced by the SSD? thanks.

hi MattQE,
 
Welcome to the Forums.
 
Just to verify, is the unit originally Windows 8 and this problem occured after you upgraded to Windows 8.1? Any changes that you made to the machine before the problem occured?
 
From the looks of it, this seems like a hardware failure but can you try the following:
1. Boot into the BIOS and set the following options (if applicable):
 
Security Tab:
Secure Boot = Disabled
 
Exit Tab:
OS Optimized Defaults = Other OS / Disabled
 
2. When done, press Fn+F10 to save and exti and observe.
 
 
Let me know how it goes.

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

When you reinstall there are some critical partitions.  You cannot leave any of those of the drive and reinstall Windows 10.  Data partitions should be OK.
To boot a USB drive as UEFI, assuming your system has that capability, you have to format the USB drive as FAT 32.  It must use an x64 bit version of Win 10.
When you boot you should be able to see a Boot Device Menu.  Look for something that shows as UEFI and boot to that.  If you don't see a UEFI option, the Bios may be set incorrectly or the USB drive is not configured correctly.

Hello, first post here...

First, some context: I have a Dell Inspiron 15R SE that came with Windows 8.

I've managed to get a working dual-boot system with Ubuntu 12.10. I can't remember exactly how I done that, but I remember that I had to disable secure boot. I think that the boot configuration those days was:
Secure boot: DisabledLoad legacy option rom: EnabledBoot list option: Legacy

This "configuration" worked perfectly for 6-7 months.

Then, one day (last week, can't remember the exact day), when I was using Windows 8 the computer crashed. I hard-rebooted and got this screen:

I've searched a lot, looking for solutions and after executed boot-repair from a Ubuntu LiveCD dozens of times I've decided to eliminate Ubuntu temporarily and focus to get a system with Windows 8 working nice.

Then I used my recovery DVDs to recover the system. Yup, Windows has booted. But when I restarted first time I got the same error. Then I, digging a solution, pressed F12 after a reboot and got here:

The highlighted option allows me to boot into Windows 8. So I went to boot options (F2) and changed the following configuration:
Load legacy option rom: DisabledBoot list option: UEFI

Now I can boot directly to Windows without need to press F12.

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.

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.

- 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 "\".

Just bought a Dell Optiplex 7010 Mini-Tower with Win 8 Pro 64-bit, 8 GB RAM, 500 GB hard drive and an Intel i5 3470 processor. Right now, it has Dell BIOS version A16.

It is normally in UEFI ON and Secure Boot ON, so that F12 on bootup (one-time boot options) does NOT normally show the CD-DVD as a boot option. OK - no problem.

However, if I reboot with F12 and select both UEFI OFF (meaning Legacy ON) and Secure Boot OFF and reboot, then F12 DOES show me the CD-DVD as a boot option, but if I actually try to boot up from a bootable CD, I get an error message.

I have practiced with two bootable CDs - a Knoppix and an Aomei Backupper, both made on earlier machines. Both these CDs work as boot-up CDs in my old XP machine, and the Aomei Backupper CD also worked in someone else's Win 7 Pro 64-bit machine.

What's wrong?

Again, please let me repeat that I am trying to boot from the CD-DVD AFTER I have turned OFF UEFI, turned ON Legacy and turned OFF Secure Boot.

Thanks.

But if you're using those settings, Windows 8 will not start.

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.

Dear Friends,

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

Laptop: ASUS UX31A-DB71, latest BIOS: 218

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

Questions:
1. Why would the system NOT boot from UEFI?
2. If I download the legitimate iso fr... Read more

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.

If a bootloader has infected your computer and it tries to load during the boot-up sequence, Secure Boot will be able to undo all the changes and thwart the ... Read more

Hello everyone
I am trying to make Windows 10 scripted installation with UEFI boot.
Every things works with normal Legacy mode in our environment and k2000.
I have made WINPE 10 boot file as a normal procedure with k2000 Media Manager (like in legacy mode). And uploaded it to k2000. Of cause I have re-cached my drivers when making new a boot source. 
I have setup our new DHCP so it can boot with UEFI and it works!, and I can see my boot sources when boot up the client in UEFI mode. 
Here comes the tricky part I can choose my newly created Windows 10 boot source with Dell's own WINPE10 drivers. Then it loads the Boot source file that I created but It stop at the Windows 10 logo it never loads the deployment menu like in legacy mode, so I cannot deploy a scripted installation.
I am stuck what could be wrong or what have I missed ? Please help
Regards,
Michael

rdubayah,
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. To run a hardare diagnostics on the computer you would start the computer and TAP the F5 key. Insert a cd/dvd in the optical drive for running the diags.

I will be replacing (Upgrading) the motherboard (and CPU) in my desktop in the near future. The current Win 10 is not UEFI. Can it be converted to UEFI (GPT) or do I have to do a "clean" install to get UEFI? I assume the answer is NO, but wanted to check.

I am not a happy camper with Windows 8.
I am confused with the Legacy and the UEFI boot methods. The reason I am confused I think, is because I read to darn much on the Internet. One bit of confusion is with respect to changing from UEFI to Legacy. It would appear from some comments that if I do that, Windows 8 won't boot anymore. I would have to change back to UEFI for indows 8 to boot. I also read that changing back to UEFI could be a major problem when trying to access the BIOS. No, I am confused. My ultimate goal is to set my laptop up to dual boot Windows 8 and Ubuntu. Like I have been doing for the last multiple years with XP and Windows 7.
Helpful comments would certainly be appreciated.

A:UEFI/Legacy

I don't quite understand what UEFI is, it is firmware, or is it Microsoft's new Boot GUI? I've set my systems to boot Legacy mode, and since I did that, I have no trouble getting into Safe Mode.

Does UEFI access your BIOS as well? That's what I'm worried about. The idea of not being able to access the BIOS from outside Windows 8 makes me itch. I think the Legacy Menu may allow that though - You can set it to Legacy, and if you can't access the Bios, then you can switch it back. I forget the command lines to set it, but they are in a tutorial here. It's BCDedit.

Hello,

I have just finished making myself a decent gaming rig and im on the last step at the moment; which is installing Windows 7. I have noticed that when trying to install Windows on my pc there's two option: one is Legacy and the other is UEFI, and since I'm not really and expert when it comes to such things, I decided to postpone the installation process until I figure this out. So, which of these should I choose as an installation method? I'd really appreciate it if someone could help me with that. Thank you!

A:UEFI or Legacy?

UEFI has some advantages over BIOS,such as:

Faster booting
Support of 128 logical partitions
Support for disks which have a size of over 2.2 TB
Support for Legacy BIOS

Since your desire is gaming,install with UEFI. There's no reason to go with BIOS unless you have old hardware.

Hello, first of all thanks for taking time helping me with my issue.

That`s the case:

I wanted to recover an Image-Backup done with a Backup Software, but the Boot-CD does not Boot on my PC. I have an Windows 10 64-Bit System.

While trying i found out it does indeed boot when i change the Bios from UEFI to Legacy.

If i recover the Image in Legacy-Mode and after that i change it again to UEFI - will Windows boot up or will there be Problems?

Is there any way to make the Boot-CD work also on UEFI?

Thanks in advance.

My XPS 8700 originally came with Windows 7 Pro, 64.  I since upgraded to Windows 10 Pro, 64.  I only now noticed that BIOS is setup for Legacy.  If I attempt to setup for UEFI MY drive is not recognized.  A check shows that the drive is setup for MBR.  I thought all XPS 8700's came setup for UEFI.  Am I stuck with Legacy or can the new drive be setup for UEFI???

I'm not 100% sure but I think UEFI requires drives to be partitioned GPT.
