UEFI Booting Of GPT Partition Doesn't Work After 2nd HDD Was Added
Nov 10, 2011
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 have 3 drives, C:, D:, and E:. E: is just a storage drive. XP was originally installed on the D: drive. I installed Windows 7 on the C: drive following the instructions at Dual Boot Installation with Windows 7 and XP. After installing Windows 7, I didn't get an option to boot XP so I used EasyBCD to add an XP entry to the boot menu. That worked, but after I boot into XP, if I shutdown or restart I get an error message about the Windows Boot Manager that says
"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem
...
etc
...
File: ootcd
Status: 0xc000000f
Info: an error occurred while attempting to read the boot configuration data."
Then I have to run startup repair from the Windows 7 disk. But then I just get stuck with Windows 7 and no boot menu entry for XP. If I try EasyBCD again, the same process results.

Whenever I connect to my wireless internet, be it when booting up the computer or changing to it via the modem cables, it refuses to work. The only way it works is if I click on the network computer in the bottom right corner and then troubleshoot for a couple mins, until the computer automatically fixes the problem. Im guessing a service or something isn't working.Ive tried buying new modem to wireless modem cables but still no luck. Obviously using Windows 7 (Ultimate)

Firstly I should say that I am primarily a mac user, and it is not my laptop I am posting about. Although I am reasonably knowledgable about Windows, I haven't used it since XP, about four years ago, and so am pretty rusty.Basically, my girlfriends computer randomly turned off about a week ago, she assumed it was a dead battery, plugged it in, and then when it turned back on it wouldn't boot displaying error message: missing operating system.As it is a Dell laptop it didn't come with any installation discs, and I totally forgot to even make a repair disc when we got the laptop. I managed to get hold of a Windows 7 Installation Disc and license key for Windows 7 Ultimate 64 bit through my university. I think the laptop was previously running Windows 7 Home Premium, but that's all I know, and I'm not entirely sure of that fact.
Anyway, burnt the .iso to disc and have tried to boot several times from DVD Drive. The laptop loads the files from the DVD fine, and gets as far as the "Starting Windows" screen, where it seems to get stuck for a few minutes, until it becomes a black screen with just a cursor (the cursor still moves). This also happens with an 64 bit repair DVD I also managed to get hold of.

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 have a Dell XPS Studio MT 435 with a two HDD RAID0 system. It has three partitions:
1) C: System,
2) D: Recovery
3) Unnnamed.
It shipped with Vista Home and I upgrade to Win 7 Home. HDD1 was causing errors...the RAID0 was dying. I was getting many BSODs.I bought Acronis True Image Home 2012.I was NOT able to clone the entire disk as an image because of the BSODs.I was able to backup (sector by sector) the C: and D: partitions. I did not backup the unnamed partition.I was also able to have Win 7 backup save off the C: partition.I then replaced to the two hard drives (WD 640 GB) with two new hard drives (Seagate Momentus XT 750 GB) and reestablished the RAID0 with these new drives.First I used the Win 7 recovery CD and its backup to restore the C: partition. The restore was successful but it wouldn't boot. There was no MBR. Windows didn't ask about nor put a MBR back on the system.Next I used Acronis recovery CD and its backup to restore the C: partition.It did ask about a MBR, which I said to do. The restore was successful and when complete, it booted up to the Win 7 login.I logged in and checked things out.Everything seemed fine, my stuff was back. Until I tried Windows Update.If failed saying that the service isn't running.I checked, the server was running so its a false error report.
I found Fix It for Windows Update and it did stuff but no good. Windows Update still fails.I then got a clue that it won't run unless Windows thinks the software is genuine. So I ran the MS validation site. It reported that I was missing files and to fix that I needed to install Windows from a genuine DVD. Which I have.I ran the installer (in custom mode, it wouldn't install in express mode as the DVD was older version). The installation almost completed and I get a dialog box saying the Win 7 was not compatible with my hardware.I don't know what to try next. Of course I have compatable hardware, it was running on the old drives and running on the new drives with a broken Windows Update.I feel that I'm so close to being fully back up and I don't want to give in and start from scratch by install Windows on a wiped disk and then loading all the programs and data file one by one back onto the system.

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 recently attempted to add a hard drive to my Lenovo W520 laptop using a CD/DVD caddy accessory designed to hold a SATA hard drive.Windows recognized the new device and according to its messages, automatically installed the required device drivers. However, when I go into Windows Explorer, the new drive is nowhere to be found.Now, I know (or at least assume) this new drive probably needs to be formatted, but shouldn't it show up within Windows Explorer even in a pre-formatted state?

I dual boot ubuntu/BTU bistro and win 7. They are all on different partitions. I had an extra partition for storage that I changed the file system so it could be read. Doing this I believe changed the order of my drives. Now on boot I get "unknown filesystem" grub rescue. I cannot load the bios or boot from cd.

The first one is the BIOS boot up screen that usually leads me to Windows. A few months ago, this vanished. I don't know if it was due to a version of Windows 7 i installed or something but whenever I turned on the PC, the screen would appear blank for a few minutes then go straight to the Windows welcome screen. I thought it was weird, but I didn't see a problem since it went to Windows so I disregarded it, which looking back is kind of dumb but I didn't want to risk doing something to the computer in the process.So a few weeks ago I was trying to partition the hard drive so I can install the Windows 8 preview on it, rebooted the computer and...nothing. It wouldn't take me to Windows to there's clearly a problem with the hard drive. I could always get a new one, but there's still the problem of the vanishing BIOS screen.

What would be the easiest way to do a dual boot? Would it be:
1)Use a second hard drive, one with XP one with Windows 7? If I did this would I be able to plug the XP drive in and see it as my D: drive? What if I went and switched it back in the bios to the XP hard would I see windows 7 stuff in D:? I’d like to do this since I have two hard drives one that is brand new.
2) Just partition my current hard drive and dual boot. If I did this would I be able to switch back and forth and see files on both boots? Also what about if I added my other new hard drive would both see it easily?
I don’t know much about dual boots so please fill me in and answer my questions.

I'm in a bit of a pickle here. My CD drive won't allow me to boot from CDs anymore, for whatever reason. I have 2 partitions on my hard drive and I'm wondering if it's possible to format the main partition by copying the windows setup files to my secondary and then somehow running them from there, whilst wiping the main one. I really don't want to reinstall without formatting, but right now I have no other option.

Windows 7 32bit on Dell 9200 4 GB RAM 2 x 500GB HDD ... with all OS updates.Been working fine.today left PC running, returned to it, power but screen was 'black'Power off to reboot - on start up (normal) desktop paints in, the spinning wheel runs for ages, then eventually all seems fine but can't do anything, only action is cursor .. nothing clickable. (incl Ctl+alt+del) HDD led on PC running permanently.Reboot in safe mode ... chose system restore .. and it shows a Windows Critical update restore point .. at a time that matches failure.?OK tried restore ... still the same.Tried Windows 7 repair disk, again selected restore ... Tried restore to next previous (2 days ago) all seems to go well, get login, desktop paints in ... then screen goes black ... all that is on it is cursor.
The only other points I can think of is that this morning (last successful boot up) it brought up a pop-up "Express files updated" with recommendation to run it ... as it gave no program, or manufacturer ... I chose not to run.On one of the boot ups during problem .an unfamiliar icon showed on desktop. "Homegroup", a green sphere, surrounded by 3 orbiting blue spheres" although not been there on any subsequent boot up.

I had an empty 70 GB partition on the left of my computer and a 230 GB on the right side but I wanted to combine them. Windows was on the 230 GB partition. I booted GParted and combined them, it copied everything from the 230 GB partition over and resized it, it took a few hours.I assumed after it wouldn't boot and all I would have to do is pop in my Windows 7 install disc and go through the repair setup. At first I ran startup repair and it would say it found a problem, and I rebooted and still nothing.. After the bios loads and it lists my DVD drives I just get a cursor _ blinking, nothing else.. No BOOTMGR missing.Odd I thought, so I ran repair again, and again it found another problem. I did this several times before it said it could not detect a problem but it still would do the same thing.I opened the cmd prompt and issued the following commands
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildocd
I tried installing a second copy of Windows 7 on a 10 GB partition on the end, it went successfully but still blinking cursor. Theres a 54 MB partition at the beginning of type Primary, the main windows one is System and the test windows 7 partition is Primary as well. I thought the first one was usually 100 MB but maybe I am wrong.Still I am stuck with a blinking cursor?

I have been given the challenge to make a way to install Windows without any installation media and without having to even touch the computer while it's installing. So far I've made a .wim image with the help of this guide and I've made an Autounattend.xml file with thI put the install.wim image in the sources directory on a flash drive and the Autounattend.xml file in the root of the flash drive, and it does exactly what I want it to - all except it's not on a partition. So I move it to a partition and add a boot entry using EasyBCD. It boots fine, but it acts like the Autounattend.xml file isn't even there. So right now I have the choice of hands free installation with media, or manual installation without media. My main question is why the Autounattend.xml file isn't working when I boot the same media from a partition

I have a Dell Inspiron laptop that got a virus on it. I tried to fix the virus but was just not able to and every time I turned the computer on it would get an error message and ask if I wanted to start windows normally, once in a while I would get a BSOD and it would reset itself. I don't remember what the error messages were because I kinda ignored the problem for a couple months and finally got around to saving what I needed and trying to do a reset. Everything went fine when I went into Dells Datasafe Restore. After it wiped the drive and re-installed I got past the Dell screen at startup and on to the windows screen then suddenly got a flash of a BSOD then the computer restarted. I went through the startup repair and got the message Failure while setup is in progress. I've been searching for a solution for a few hours now and I haven't found one. I don't have a recovery disk (I was just trying to use the partition) and I don't have a windows 7 cd. Where do I go from here?

I recently made a separate partition on my HD (C), let's call it F. I wanted to load up windows xp onto that small partition, F, so as to see if it would allow me to operate better, as I have a gaming laptop that seems to be suffering from a memory hog svchost. Anyway, now that I've booted up to the F partition and working in XP, I find that I dislike it, I also can't figure out how to connect to the internet. My issue is, I can't figure out how to boot to the C, my Windows 7, the original OS. I'm not given an option upon startup and I can't find anything in my BIOS that is obviously pertaining to my issue.

I have a laptop with twin HDDs and I have Vista on the C: partition on Drive 1. I created a new partition G: on Drive 2 and, while Vista was running, inserted the Win 7 disc and started installation to G:. All went perfectly and I have retained my original partitions with drive letters and labels, plus a new G: partition labeled Win 7. All seems to be working fine.Now I heard from a geeky friend that BOTH OS should be running on C: and that windows has some clever way of making that work. Is this true - and are there any disadvantages continuing installing MANY apps on G:?

I recently (~2-3 months ago) installed windows 7 on a brand new 1TB hard drive. This hard drive is broken into two partitions - C & G. Windows 7 is installed on C; and G is only for data storage etc. Here is the description of partition C from Disk Management:
C: Simple Basic NTFS Healthy (Boot, Page File, Active, Crash Dump, Primary Partition) 98 GB
Unfortunately, "System" is missing from that description. Somehow "System" ended up on hard drive L - an old 80GB IDE drive that has migrated from build-to-build. This drive has just started on the *hopefully* slow road to death. I decided to retire this drive when I discovered I couldn't securely erase it because it is the System partition (there is only one partition on this drive).
So, how I can relocate the system drive data to another drive (preferably C) in the safest way possible. I found a solution here: [URL]. But I don't want to copy the entire contents of L to a new drive, all I want is the data needed for booting, and to securely erase everything else on L. Looking around, it seems I may be able to boot from a Windows 7 repair disk and recreate the system files on C, but this seems risky and likely to require a full re-install if something goes wrong.

Windows 7 has it's own 80gb harddrive but i have another HDD with Ubuntu 9.10 in a 20GB partition and a sharedNTFS in the remaining 130~ GB.
The NTFS partition used to show up in 'My Computer' fine, but after re-installing Ubuntu 9.10 it doesn't. (NO i have not erased the entire disc as i can still access it in Ubuntu and it has all my files etc on)
Any ideas on how to get it to show up? it's even missing from the disc manager.

really have never seen anything quite like this. When I boot up my PC and it gets to the desktop, a program window pops up and the mouse and keyboard will not work.Therefore, I cannot clear the program from the desktop or go anywhere to run scans or the like to see if the problem is virus related. When I go into safe mode, it does the same thing. I tried restoring to last known configuration with no System Restore shows no restore points. I can't do anything including get you information on my PC. I am running Windows 7 32 bit on a HP/Compaq DC 7600 C/PD 950. I am running Avast Anti-Virus Suite Pro. Regardless once on the desktop, I can not go anywhere. What the heck? Right now I am working on my laptop.

So heres my problem: I installed Win 7 on a drive a while back and earlier today I decided that I needed more hard drive space. I saw that I had 100gb of unallocated space on the drive, but it was behind my Windows 7 partition, making it impossible to resize that partition. So I defragged with Perfect Disk 10 which moves all the files to the back of the partition, cleaned up, disabled all the usual things, ran defragger again, and then booted into a live cd of GParted. I then proceeded to move my Windows 7 partition behind the unallocated space so I could extend the volume.
Unfortunately, something went wrong and now I get the error message "Disk boot failure, please instert system disk and hit enter." So I followed the directions and ran startup repair, tried manually creating the bootmgr, and ran all the tests, but it still doesn't work. Luckily for me, I was able to reinstall Windows 7 on the unallocated space so I can at least get to the files on my other drive, which I discovered are all perfectly fine. I'm hoping this will be a quick fix since it seems like all the files are ok. What should I do so that I can boot back into that partition?
Long story short, I tried moving the partition, and something went wrong, and now I can't boot into that drive. I installed another copy of Win 7 on another partition and all the files are ok. What do I need to do to the original partition to get it to boot again?

i installed windows 7, and everything seemed to work fine.
installed a bunch of programs, they also all seem to work.
but then i decided to do some backups; i created the rescue cd using windows, and then cloned the hard drive also using windows 7.
but then i noticed the backup program, and decided to click on "set up backup"; nothing happens.
if i try the same from a disk drive/properties (ie click on backup there) nothing happens either.
any ideas? maybe something i installed broke this, but it seems like a pretty basic function to break like this.
