Windows 7 Stops Booting In UEFI Mode After Adding Another Hard Drive?
Aug 17, 2012
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 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...

So, I've added a second hard drive to my Windows machine and now it will not boot up. I added the new hard drive on SATA 3. The original is SATA 1, and my DVD is SATA 0. This is how it's always been; I've changed nothing else. I don't have any idea where to start fixing this. I have a dual boot with Ubuntu on the same SATA drive 1, and that boots just fine. I switched on the new hard drive in the BIOS, and flipped a few other options on and off to no avail.When the computer boots I choose the Win7 install. Then it will take me to a screen that asks me if I want to start windows normally, or do a disk repair. Starting normally gets you nowhere, it will just end up resetting the computer. Starting the disk check will do a scan for a few minutes and then ask me if I want to send an error report. Clicking yes or no doesn't seem to matter because after that the only option is to shutdown or reboot.When this first started I at one point had the option to do a system restore, but I didn't think it was necessary so I didn't. I no longer receive that option or I would try it at this point

My company is running several XP machines. All of these machines will need to have a hard drive added to them that will be imaged with our corporate Windows 7 image. How can I get the Windows 7 bootloader to recognize the XP install? We don't want to have to use a 3rd party app such as EasyBCD. We would like to create a batch file that utilizes the capabilities of bcdedit.exe to modify the bootloader so we can repeat the process multiple times with out installing the 3rd party app. (plus, the boss doesn't want us using the 3rd party app).

I installed Ubuntu on my computer a few months ago and created another partition for it on my 1TB hard drive. I didn't really care for Ubuntu so I decided to delete the partition it was on. That might have been a mistake. Well, now there's 87.68GB of free space on my hard disk that I can't use and I don't know how to add it back to my c: partition.
There was another post about this a couple years ago, but I don't understand the instructions and am not actually sure if it worked. Can someone explain how to do this, please? I'm not completely computer illiterate, but I'm not familiar with partitioning disks. It was just the one time with Ubuntu.

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 running a custom built system, but want to add a used hard drive to the system so I can copy all of the old important files off it to the new hard drive. I had them all on an external, but the external failed a day or two after the backup, just my luck.Is there any risk in me just plugging in the second hard drive to a SATA port?

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).

I have a dead laptop, I believe it was the hard drive, anyway. I took the hard drive out, connected it to my Network computer, all looks well, I heard it spinning (Good sign?) and then I booted the computer, it didn't actually load windows 7, it spent like a good 10-15mins saying "Loading windows 7" so I turned it off, moved the SATA cable to a different slot, it booted.. then when trying to detect the drive, it doesn't exist. I will need to format it, as it does have windows 7 on that drive aswell.

I have a HP Touchsmart IQ500. Turning my computer PC on today, all I got was a blue HP invent screen with setup, boot menu, system recovery, and system diagnosis, and I could not get past it. I entered the BIOS and figured out that the hard drive was listed as "not installed." Pretty sure that is the main problem.I tried a system restore (with the Windows 7 install disc), but I guess the computer couldn't read the hard drive enough to enter safe mode (I tried restarting and F8ing several times). I put in an external hard drive, and the BIOS read it; however, windows does not allow you to partition an OS on a hard drive.

Ok I have a emachine e725 running windows 7 32bit and a acer running on windows vista. My emachine recently crashed in the blue screen and I tried to complete a system restore. I was able to get through the advanced boot menu and use the repair your computer option to restore windows. During the windows setup process I got another blue screen and the computer restarting. It then started the process over and once it got to the step that says windows is preparing setup, it gives an error msg saying something along the lines of windows was interupted and needs to restart to complete installation, and it has an option to press ok. This cycle continues and I can not open in safe mode because it says "windows can not complete the installation in safemode. Also the option to repair your computer in the advanced menu options is no longer available. So after wrestling with windows starting up I decided to create a back up and restore disc on my acer for my windows 7 computer. I tried putting it on a disc but it would not boot. So I tried creating a installation disc of windows 7 and tried booting from the cdrom drive. Once I did that I got a error msg saying "device driver not found: MSCD001 No valid cdrom device drivers selected. It then gives me the A:>. Im not sure if I created the disc wrong since I cant unzip the entire file I downloaded with needing an encryption password.

I have a laptop that has Vista installed on it. I have an upgrade disc for Windows 7 and I am thinking about performing a "clean installation" over the Vista OS - which I know is allowed, on the following link;click here Now, I would like to create another partition (on the same hard drive) and install Vista (using the same disc that it came with the laptop) onto that blank hard drive partition

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?

the screen glitches with pink, white, and green tiles and lines, the cursor disappears, the screen goes black, and the hard drive stops spinning. All the lights on the front of the computer stay on, the fans stay on, and the monitor doesn't say anything about not receiving a signal. The first time it happened I tried turning it on right away and it booted up and let me sign in, but as it was loading the desktop and icons it glitched again, and froze. after I shut down and let it sit for a while it worked just fine until the next day when it did the same thing again, but twice in one day and with a shorter time between freezes. Today I had a WerFault.exe error pop up and when I clicked ok on it the bottom half of my screen turned pinkish and the computer froze when I restarted the pink tone was still there but it did not show up on any windows that I opened and when the background changed it went away.

I'm using a decent Lenovo B560 laptop, and when playing games or running programs linked to the hard drive disk, it freezes intermittently.
Not sure what's causing it, but the whirring of the disk drive can be heard for about 3 seconds, at which point it slows down, and then the game freezes until the hard drive starts whirring again. It doesn't seem to be able to keep itself running in order to keep playback fluid; it just keeps spinning long enough to power 3-4 seconds of playback.
System is 7 64 bit, with Intel Core i5 CPU M480 @
2.67GHz
3GB RAM

My computer yesterday was an XP machine with one hard drive. I wanted to test Windows 7 but I was afraid I would screw something up with my XP drive in the process. We'll call this Drive A.
Yesterday I bought a new hard drive, Drive B. I downloaded the Windows 7 ISO, got some drivers, and turned off my computer. I physically removed Drive A from the computer and put Drive B in. I started the computer and put the DVD in. Setup was fine, I had some trouble with getting the onboard NIC to work but I was able to overcome.
Now I needed to get back into my XP install to get some stuff done (play video games). I shut my computer down, pulled out Drive B, put Drive A back in and booted up. But I got a boot error message, and it looks like it's a Windows 7 Boot error message. How can this be if I removed the hard drive.
0xc000000e
The boot selection failed because a required device is inaccessible
It's almost as if my computer is trying to boot to Windows 7 even though I removed the hard drive containing the operating system. How do I get into my XP system? The drive is fine, I connected it as a slave and I can access the files on there. I'm guess Windows 7 makes some kind of change on the motherboard that forces it to boot to 7?

My friend asked me to fix her laptop, which has been failing to boot, getting as far as the blue Windows 7 login screen then hanging. The login UI doesn't load, it's just the blue background.I tried to re-install Windows from the boot disc, but when I put in the disc, I wasn't able to boot from it. Instead the computer booted from the hard-drive again and hung at the same place. This is after changing the boot priority in the BIOS.Since the laptop is out of warranty, and is to all intents and purposes a brick, I removed the Hard-drive, and connected it to my computer to see if I could reformat the drive from there. The thing that has really puzzled me though, is that my computer wouldn't boot when this hard drive was attached, despite running fine before I attached the drive, and after I removed it.
Which leads me to think there's possibly a really malicious virus or something on the drive, which makes it the default boot device, despite having a corrupted operating system installed that won't boot.

Motherboard: Asus A8N5X
So after the hard drive fiasco that I reported in another thread, I got clever and decided to create an "Emergency Boot Drive" that would have Windows on it as well as some utilities for data recovery. I took one of the many old hard drives that I have floating around and plugged it into the computer AND unplugged my other two drives. Then I ran Windows Install off the DVD and installed Windows to the old drive. I installed my software. All was good. I plugged in the other two drives and tried to boot from the "Emergency" drive and it worked fine.Last step was to unplug the emergency drive from the motherboard, connect it via USB and try to boot. The BIOS sees the drive and I tell it to boot from the drive. So the computer is booting. The "Starting Windows" message comes up and then the system reboots. This happens everytime I try it.Does Windows reset the USB ports so that the drive suddenly vanishes?

I had my old hard drive installed in my Windows 7 computer. It worked for several months but now it started booting from the old drive that still has Windows Vista on it. My simple fix has been to unplug that drive while booting it up. Can I just delete the Windows Vista files?

I am trying to wipe my current XP installation clean and move on to Windows 7.
I first tried to install the setup.exe (Custom install option of course) from within the XP OS, but soon discovered you cannot do that and wipe out my only partition on C: at the same time.
I don't have a DVD-RW drive to write a boot disk, so instead I am trying to install through my external hard drive. I meticulously followed this tutorial from PC World yet when I instruct the PC in BIOS to boot from the external hard drive, I keep getting an "invalid system disk, press any key" error when the computer boots and looks for the setup files. This is despite the fact that setup seems to work perfectly from within the XP OS.
PC World tutorial:
Install Windows 7 From an External Hard Drive - PC World
Can anyone please offer me any helpful advice to get the external hard drive setup to work or help me find a way to install 7 from within XP?
Anyone know exactly why I keep getting the "invalid disk" error each time when I try to boot from my external hard drive? As mentioned in the PC World tutorial, I marked the external hard drive as an active partition and the setup files seem to work fine from within XP. If it helps, in the external hard drive root folder is both the Windows 7 ISO and all the files contained (which I extracted using PowerISO).

After trying to scan my computer with tdskiller (I believe its called) to remove some viruses, I was asked to reboot. When I did, my backround desktop picture turned black, files seemed to be missing from my desktop and a window poped up scanning and telling me how many errors I had. Shortly after I got about 20 error pop up messages. I rebooted my computer and more files were missing to the point all I had was recycle bin, and two other programs.
Now the computer runs only in safe mode, No matter what I do (pressing f8 - start in normal mode) nothing works. I cant get internet access, and worst of all, I cant even system restore or even recover it back to to the malfunctioners option due to errors. I am stuck and do not know what else to try.
Ive tried the repair option in dos aswell and it just keeps me in the "Loading window files" screen, as I left it there for nearly four hours im guessing that was not going to work.

My OS of choice back then was MS Windows, however after Windows XP I moved to OSX. About two years ago I knew I needed to get back involved with Windows and bought my Lenovo Laptop running Windows 7 Home Premium. I then installed Windows 8 Consumer Preview on a different partition and upgraded to Windows 8 Pro when it became available. I am now looking to install a distro of Linux and can't seem to find any information of doing so. I don't know which Windows partition it would be best to install it on 7 or 8. Also I understand that Ubuntu have a Windows Installer wubi, but I have heard horror stories after the installation. My main fear is losing Windows 7 or 8 and if the entire process is too risky I'll just leave it altogether. So I guess my question is has anyone installed a Linux distro on a PC which originally came pre installed with Windows 7 and then added Windows 8 to a partition?

I have been getting BSOD errors whenever booting into regular mode. Safe mode is fine (I have tweaked the registry so I have sound in safe mode) My system specs are in my profile, but used Winaudit for full specs. The winaudit report in formatted text is too big for an attachment. I have 2 attachments to this post, including zipped up minidumps. Could my registry tweak for sound have something to do with this? Perfmon /report was run, but it says:
An error occured while attempting to generate the report. The system cannot find the path specified.
