Boot UEFI From Wake On Lan, Or Convert UEFI MBR To Legacy
Nov 16, 2012
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?

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...

I'm still trying to get a hang of how UEFI works. I did take a look at it when I went to install my OS (And again when i got a SSD), but I couldn't make heads or tails of it and used BIOS.
does UEFI make a drastic difference over BIOS, and can I convert without having to do a complete wipe and install? or how would go about switching to EFI, or is it worth it?

this has been dealt with in various places but not to my total satisfaction. So bear with me if the answer is hidden somewhere in the forum.I've got an oem asus with 2 hdds the first of which has Win 7 64 home pre-installed via uefi boot manager. It is a gpt formatted disk. The second disk is empty and is set up with mbr. I wish to dual boot onto the second disk with Win 7 32 Pro but fear a rejection due to the fact appparenly Uefi will not manage 32 bit installs/boots. More to the point , will the mbr variance on the 2nd disk somehow make for an exception to this 32bit 'prejudice' on the part of uefi or simply make matters worse? My bios has a single option regarding a legacy setting connected with uefi which is disabled. PxO.or rather. Gregrocker seems to think obviating the problem with 2 physically separate installs (i.e. Hdd disconnect) will allow a Bios based boot as opposed to a Uefi/Windows managed one. Is this workaround a sure thing and my only option or is there a practical way to go the classic route with the auto boot loader screen on start up? Perhaps a better way to put it is..on dual boot systems is it true that you can't have BOTH uefi and the bios directing the show. You gotta choose one or the other. Frankly, to my novice mind this whole problem seems to be a regression from the XP days.

I am swapping out my older X58 BIOS motherboard for a UEFI motherboard with a new Ivy Bridge i5. I'd rather not have to reinstall Windows 7, and just want to make sure I can swap the boards and CPUs without issue.

I am installing Windows on my new SSD. I made the disk GPT (instead of MBR), and installed Windows (tried 5 times now) with similar results. Either error 0xc0000225 or boot loop of "Windows is loading files" ... or it throws me back to my BIOS Boot selection screen where I came from ... what might be the problem? Windows 7 still cant handle GPT partitions? Or it doesnt like the new SSD? I managed to install and reboot successfully once by removing all other drives (except the SSD which I am installing into), works, I can enter Windows. Then once I installed back the other HDDs, it fails again ...

Since UEFI exists, some people talk about BIOS replacement by UEFI in short-term (2011 for exemple) (see "News").Who never has problem with BIOS bugs ? I must fight against several problems on one of my mobos because of its incorrect BIOS code, essentially for long time boot BIOS and very buggy S3 sleep mode.However, when I read many posts about people who have installed their Windows 7 x64 in UEFI mode, I'm afraid of some new problems that UEFI causes, according to these people, even during a Windows session, even if installation was fine.I would like to know your experience about UEFI, on motherboards which support it (my motherboard is an Intel DG45ID which proposes UEFI boot).

Have the UEFI Option in the boot menu of the ASUS K42F notebook. Regrettably, boot to USB is not an apparent option. Have emailed Asus support and the reply demonstrated no knowledge of the feature. There is an option that allows the entry of "command line" entries. The setup utilities are from American Megatrends (AMI).

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 Windows 7 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).

I have an Asus Z68 mainboard with UEFI-BIOS. Windows 7 Professional 64bit is installed in UEFI mode on a GPT partitioned drive (SSD). It worked flawlessly.Now I added my second, old harddrive, that is still MBR formatted.Windows won't start anymore, instead I am seeing "Windows is loading files", then a blinking cursor, and that's all.I have two options in BIOS regarding boot priority:
1) I can boot from the SSD as primary priority
2) I can select an option called "Windows Boot loader", I think this refers to the UEFI boot code that Windows wrote to the UEFI.
If I select the first option, I get the "Windows is loading files screen" and then the "Windows has detected a startup error, do you want to repair the system startup" screen. If I select "Start Windows normally", I get a blinking cursor and then nothing. If I select "Repair startup", I see "Windows is loading files", and then again the "Startup repair screen". It is an endless loop.If I select the second option, I get "Windows is loading files", then a blinking cursor, and nothing more.Is there any way to get my Windows to boot again without disconnecting or re-partitioning the old harddrive? Note that the old harddrive is NOT for booting, as it is just a datastore.

I'm using a GA z77x-UD5H and it has its own UEFI dualBios. I am using an external dvd drive to try and install windows 7 because I just built this pc. I have nothing on my HDD yet. All I am trying to do is figure out how to boot using the DVD drive to install windows.

Just built a new PC, specs as follows:
3770K
32GB DDR3
ASRock Z77 Extreme6
Crucial M4 128GB (from previous build)
OCZ Vertex 4 128GB
WD 400GB (from previous previous build)
I got Windows 7 up and running on the Crucial drive (connected at SATA3_1, with the WD connected and functioning on SATA3_A1) and then decided it was time to get Xubuntu up and running on the OCZ (SATA3_0). So I installed rEFInd on the Crucial's ESP and it worked - I was able to launch Windows 7 from the rEFInd menu. I then disconnected the Crucial and connected the OCZ, and installed Xubuntu. In the UEFI, I set rEFInd as the boot device/manager, and from the rEFInd menu I can select Xubuntu and Windows 7 - great. However, I can only actually boot Xubuntu; booting Windows 7 results in a Windows Error Recovery loop.Disconnecting all but the Crucial SSD, I can get into Startup Repair. It attempts repair for several minutes, fails with the following details:Quote :Problem signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown

This week, I encountered the following strange problem for which I haven't found a final solution so far, though I have found some bandaids. But having a complete solution -or at least a reason why this problem occurs- would be great:I have a working installation of Windows 7 Professional x64 in UEFI mode. The main disk, SSD #1, contains the following partitions (using GPT): ESP, MSR, system, data. An additional disk, HD #2, with a single data partition (using MBR) is also attached to the system. With this setup, everything works fine.Now, after adding another disk, HD #3, to the system -my old system disk (bootable, using MBR, one active primary partition and an extend partition with three logical disks)- Windows will no longer boots completely: The boot process begins, the Windows logo is shown. Then, a message is shown in text mode "Windows is loading files" with a loading bar. After a while the boot process stops and I am dropped into the EFI shell. After removing the offending HD #3, Windows boots normally again.
I tried removing HD #2 and only attaching HD #3 together with SSD #1, but this yielded the same problem. Using SSD #1 by itself works fine though. Booting from a Linux live-cd works without problems. All disks and partitions are found and can be mounted. There, I erased the disk signature from the offending HD #3 and now Windows was able to boot and also found all disks and partitions correctly. But after a reboot the same problem reappeared

I setup an XP/Windows 7 dual boot on two drives. Currently C: Windows 7, D:XP
Love Windows 7 and now I'm ready to convert to single boot Windows 7.
I'm not real savy re. bcdedit so will need very detailed instructions
I did find the command line in Windows 7 by going through accessories but I'm scared to go further without help.
Eventually I want to clean up the D:xp and use it for storage etc.
I'm guessing this procedure may have already be written up but I can't seem to find it.

I don't have an internet connection after boot up or after I wake the system up from sleep. This happens just about everytime, the troubleshooter have no problem fixing it every time. There is nothing wrong with the network as I still get a dial tone on the telephone.

I am running Windows 7 Pro x64 and I am having an issue where my computer goes into sleep mode, fails to wake from sleep, strangely resumes its state once I do a cold restart, and then after restarting again, refuses to boot.Computer goes to sleep based on the time set in the Balance Power options scheme. Fine. Often, computer wakes up perfectly fine from moving the mouse or pressing a key. Fine. Very occasionally however, upon waking up the computer, the lights, keyboard lights, fans and everything else except for the display comes on. I am forced to do a cold shutdown by pressing the reset button. Upon booting up, Windows displays "Restarting Windows" rather than "Starting Windows" and resumes its state when it went to sleep. Strange but OK. Everything seems to work normally. The problems come in when I then do a shutdown or restart after it has resumed from the cold shutdown. The computer shuts down perfectly fine but during the next boot, freezes right during the animation of the windows logo and immediately restarts the computer and launches into the DOS-looking prompt asking whether I want to do a Startup Repair because the computer failed to boot.
I have tried Startup Repair from HD and from the Windows disc and neither have done anything. I am usually forced to just reformat everything and start anew. This problem recently started occurring after I installed an Intel X-25m 120GB ssd and put the Windows partition on it. I'm not sure if that's related to the problem. Also, all of my power options are set to the Windows default.
My hardware is:
CPU: Intel Core 2 Duo E6600 factory 2.4Ghz
RAM: Corsair Dominator DDR2 4x1GB
HDD: Intel X25m SSD 120GB (Windows) + Seagate 400GB HDD (everything else)
Mobo: Intel DG965OT
Video: ATI HIS Radeon HD 5770

I installed Ubuntu on a older Toshiba laptop. When I boot up it asks me to select either Windows 7 or Ubuntu. I want to get rid of the Ubuntu disk partition and give that 2.9 GB space to my primary hard drive. I go into compmgmt.msc but I can't execute any commands on that disk partition.

Logmein software is able to wake the computer up with On Board Wake up is disabled or enabled in BIOS.I have also Toshiba L505D.Logmein software can wake the computer up only if Wake up on LAN is enabled in BIOS.What is the difference between ASUS BIOS's On Board Wake up option and Toshiba BIOS's Wake up on LAN option? UPDATE: I found out that ASUS's Option was for diskless boot and using network hard disks as hard disks. Nothing to do with Wake up on LAN.

I tried installing the legacy 10.2 driver downloaded from AMD website but after installation I restart the PC, I see the windows 7 loading logo then I can't see the welcome screen but I hear windows startup sound! to be able to see my desktop again I have to hard restart the PC and login to safemode and remove ATI driver (which shows under unknown devices)
The problem isn't with ATI driver only it seems that I can't see my desktop with (microsoft's Standard VGA Graphics Adapter driver) also (check attached image)
I tried removing ATI driver and clean the system with "AMD Catalyst TwL Cleaner v3.9.2" but I got the same problem after using.

This time the message was DES has been disabled. Enable it or some such nonsense. I have no clue what it means. Luckily I had a PS/2 keyboard to use to hit the ENTER key or my PC would have been disabled again.
When I got back online, every website that uses PWs had to be logged back into. Sites that I never have to log into once I've done it once.
What is this DES and is it related to cookies?

I am planning to perform a clean install of Windows 7 on my Dell Vista PC (as I understand this is better in the long term than an upgrade).
My PC has a 10GB D: drive, which it came installed with, 'Recovery'. Is this something I should delete/format as part of the Windows 7 upgrade process (and will I get invited to create anew one?), or I should I just leave it be? Apologies if this is a simple question/answer, but I'm a bit snowed under with children today and I don't have time for Google and 'due diligence'!

I'm running a 32 bit windows point of sale application in one of the family run business stores. The PC has a athlon xp 2000+ and 128MB RAM and has WinXP as the OS. The program developer in his latest requirements says a pentium class 1.5ghz processor is a minimum with 1.5GB RAM. I want to know if it is worth the upgrade to an i3 with 4 or 8 GB of memory and Win 7. Is there a way I can measure the increase? The program has a foxpro database as the backend.

Having spent a while checking which of my existing applications will run under Windows 7 I have now learned enough to realise that my conclusions may have been affected by XP Mode which I believe exists only in Windows 7 Professional & Ultimate.
My current copy of Windows 7 is the Windows 7 Release Candidate which I believe is Windows 7 Ultimate, but the PC I hope to buy after Christmas will most likely be Windows 7 Home Premium.
Can anyone advise how I inhibit XP mode so I can test compatibility with Home Premium and/or how I can tell whether a legacy applications is running in Windows 7 Ultimate courtesy of XP mode, and therefore may not run under Windows 7 Home Premium?

I'll start with when I installed Windows XP. My ATI X1650 worked fine when I downloaded the latest drivers from the ATI website. (at the time it was 8.11) Well, other then openGL. DirectX 9 worked fine on it but openGL had issues. I ended up installing the drivers on that came with it and everything was happy.
So, now on to Windows 7. I installed Windows 7 painlessly and everything was working fine. (It even recognized my card and dual monitors without a problem.) And then when I tried an openGL game openGL wouldn't work. So, I found my drivers from forever ago (8.11 which didn't work the first time...) and installed those. Poof, openGL worked. And then I hit my other problem. Aero didn't work now.
So I went online to try and find a new driver and found that ATI had put my card on legacy support. (Basically Windows would ship with all the drivers my card would need. And it did, other than openGL.) So, I went to Device manager and had it check for an updated driver. And guess what, it wouldn't install the original Microsoft driver over my old one. (which I installed to get openGL working)
So basically I need to find some way to get the original Microsoft Windows 7 display driver to install over my old driver without uninstalling my old driver. (I've tried installing the newest ATI drivers (9.2) with support for my card and that didn't work.)

I have an Abit NF7-S mobo (5+ yrs old) that has an nForce2 Ultra 400 + MCP-T chipset. The nvidia site has classified this as legacy, and only has the download for Vista.
Well I usually prefer to install the 'official' drivers, as MS ones seem to be at times problematic from experience. However I went along with installing the ones provided my microsoft update. All components in Device Manager seem to have been installed, and the OS is working without a problem.
But the voice within me still prefers the 'official' vendor software. Would the vista one provided by nvidia work on Windows 7. I use to get a nice small app to control audio in the official release, which I am obviously not getting in the MS trimmed version.
I also have a SATA 150 RAID (Silicon Image Sil 3112A SATA PCI Controller) on the NF7-S which has the same issue as above. All working.. but for that voice.
