Reinstall Windows 7 Boot Loader?
Jan 24, 2011
I have an HP pavilion dv4-1555dx laptop that I was trying to install Linux mint 10 gnome on a PNY 8GB flash drive, I forgot to have Linux install grub to the flash drive, so it ended up installing grub to the HDD, now I need to reinstall the windows 7 boot loader but HP didn't send a windows 7 boot disk with the system (OEM windows 7) so I can't jut boot the cd and use the recovery counsel unless there is somewhere online that I can get an iso from, or is there another way?

I had windows 7 originally Installed on my Laptop. I then Installed Ubuntu 9.10 Desktop version, and it installed the grub boot loader
(All on 1 single HD, each OS is on its own partition.)
This boot loader was used to dual boot between windows and Linux. However now the grub boot loader is broken, and I was talking to some people how knew about Ubuntu, and they said to just delete its partition, which I did.
Now when I boot from my HD I just get a broken grub boot loader, and can’t get even get into my Win 7. Now I just want to get ride of this Grub boot loader, and get Windows 7 MBR back. I have booted from my windows 7 recovery disc, and have done:
Startup Repair – It found no problems, but HD still only boots to broken grub boot loader
System Restore – I restored to before I was having this problem, but HD still only boots to broken grub boot loader
I am trying to figure out what commands to enter in the command prompt to repair the MBR, or maybe just view what partitions are in my computer, and then completely delete the one with Grub on it.
If I type bcdedit I get this:
Windows Boot Manager
Identifier:{bootmgr}
Device:partition = C:
Description:Windows Boot Manager
Inherit:{globalsettings}
Default:{default}
Displayorder:{default}
Windows Boot Loader
Identifier:{default}
Device:partition = D:
Path:Windowssystem32winload.exe
Description:Windows 7
Inherit:{bootsequencesettings]
Recoveryenabled: yes
Osdevice:partition = D:
Systemroot: windows
Nx:OptIn
According to this everything looks fine, The C partition is that 100MB system reserved boot partition that windows 7 creates, and the D partition is a 100GB partition that I created on the HardDrive that windows 7 was installed to. I don’t understand why the windows boot loader will not boot, somehow the grub boot loader is still over riding it, even though I deleted the partition that ubuntu was installed on, and where the grub should have been installed as well.
From the command prompt, if I use diskpart, there are only 2 partitions, a 100MB one, and a 100GB one. Those are C and D respectively, so I am not sure how the grub is still loading unless it installed itself to a NTFS partition if that is even possible.
Does anyone know what commands I can try to repair or recreate the MBR so that windows 7 will load, or maybe commands to delete this Grub boot loader?

I have a laptop which until yesterday was dual boot (Windows 7 and SLES11). However I decided I would rather just use Windows with VMWare for any Linux needs. To do this I deleted the Linux partitions (OS, workspace, swap) from within Windows and used this extra space to add to my workspace partition on Windows and create a new partition for my VM's to sit.I got all this working very nicely and was happy with it until I rebooted to machine to see GRUB was still set to be the boot loader which is unable to do anything with no Linux partitions.What I do have is the Windows 7 Reinstallation DVD that came with the laptop however the DVD drive of my laptop is broken. I am currently writing this with a MacBook Pro (Mountain Lion) and so the only solution I can think of is using media oN DVD, and burning this to a bootable USB using the Mac and then setting up BIOS on the 'broken' laptop to boot from DVD. However I am not sure how to create a 'bootable' USB.
1) Can I use my Windows 7 reinstallation disc to recover Windows boot manager
2) If so can I do this via USB?
3) How could I make my USB 'bootable' using my Macbook Pro
4) What are the steps for recovering boot manager from the installation media
5) What is the more elegant way to 'delete' Linux partitions and ensure Windows Boot Manager works (I may also run into this problem with a workstation I set up in same way yesterday but have yet to reboot0

I have a PC with 2 hard drives- the first hard drive has a single partition and windows 7 64-bit is installed on this hard disk.Now I wish to install CentOS 6 on the first partition of the second hard disk.I have created the dvd for installing Cent OS also.How do I configure the boot loader in Windows? If I install Linux on second hard disk, will this overwrite the Windows Boot Loader? How do I create a dual boot system so that the windows boot loader correctly shows linux as an option, so that I am able to load either Windows 7 (existing) or Linux(on second hard disk- not yet installed)

I have two harddrives in my computer, one is 750GB and just has a bunch of different files from my older computer (documents, movies, etc, but no traces operating system). My other harddrive is 1TB and has Windows 7 on it (which I'm typing from now). For some reason (I think after I installed a Windows Update), when I restart the computer it says, "Bootmgr is missing. Press CTR+ALT+DEL to restart". Before, this had never happened, so I figured out that I had to manually go into my HP boot menu (by pressing ESC when I first start the computer) and then choose my 1TB harddrive to boot into Windows 7. This is kind of a pain.

is there a way to have windows put the boot loader on a drive of your choosing? I have 2 HDDs in my computer and from what I can tell windows put its boot loader on my other drive. is there a way (other then disconnecting the other one) to get windows to put the boot loader on the other drive like change priority in the BIOs?

I recently installed Windows 7 on two different hard drives in the same computer.When installing one I disconnected the other drive, and when the first one was installed, I disconnected the first drive and installed it on the other drive.
Now only the second Windows is loaded each time I turn on the computer and boot loader screen where you can choose the OS does not show up.What went wrong and is there any possibility to restore it?

I've routinely dual booted Linux and Windows over the years, but yesterday I hit a bit of a snag. I had Windows 7 and Vista both installed on a single hard disk. Since it had been awhile since I had booted Vista I decided to delete the partition and install Linux there. What I did not realize is that when I installed 7 it left the BCD on the Vista partition. So, when I installed Linux I effectively blew away my Windows boot loader.I've tried a hundred things at this point without much luck, including the "nuclear holocaust" / manual rebuild of BCD from:Recovering the Vista Bootloader from the DVD - NeoSmart Technologies WikiA few questions / thoughts from my google searches:* Is there anything needed in /boot other than the BCD?
* I am wondering if the "active" / "boot" partition flag is causing me trouble. hen I was trying to rebuild the BCD manually using bcdedit i was getting errors that the partition was not flagged active. I tried to use diskpart to flag it active but it said that the partition type was not valid for the active flag? I was able to set it active using the Linux gparted partition manager, but I can't understand why diskpart would not flag it.* Is it possible to have your oot on a different partition then Windows? The recovery console is mapping C: to my "applications" drive and D: to my "system" drive which contains Windows. I was wondering if I need to put oot on C: instead of D:

This is quite a long story, So let me get straight to the point.On my Dell Optiplex 360 Computer (Windows 7-Ultimate) I partitioned the hard drive to make space for another windows installation. I then installed Windows Vista Ultimate on it.All of that went successfully but after a while it became useless for me and my computer.

Is it possible to install Windows 7 (to a different hard drive/partition) by mounting the iso, but then not have it install a boot loader? Obviously you'd have to be using a pre-existing OS to be mounting the iso file, but I can't seem to think of a way for it to not install a boot loader.
I know it's possible to install and then afterwards remove all the boot loader stuff, but it's just a hassle to boot into the DVDs and do all the rebuildbcd or fixmbr stuff.
Also I am aware I could just burn the iso to DVD and install it from that in order to not get a bootloader, but I'd like to know if it's at all possible via mounting the iso.

My laptop apparently is having a hard time booting. I start it up, it will display the blinking cursor and stay like that forever, i hard shut it down and the BIOS will search for new hardware (as its suppose to) and then the blinking cursor will appear for around a minute before booting up! this is really annoying and ive already Reset the BIOS to default and Reinstalled windows (deleted all Partitions and made one)

I know this does not necessarily pertain to Windows installation, but I did not know where else to place this thread. I know it is possible to burn isos to a thumb drive, but is there a way to put a boot loader on a thumb drive so I can have many images on separate partitions? For example, I want to partition my 32GB thumb drive into 700MB partitions, so that I can have Clonezilla live on one, GParted on another, and maybe the Windows 7 repair disk on another. Is this possible?

All I did was open a video strored locally with no connection to the internet. Shut down computer properly. I go to start it up and start up repair kick in. I have let the thing run on startup repair over night and a total of 12 straight hours. It reboots once, maybe even twice. Then it just sit a says attempting repairs. I just did a hard shut done. I was able to pull the data off using Uburba (not sure of the spelling). The USB 2.0 is not recognized in start up repair command prompt. I had a image saved to a CD. I can't get past the username password. The one I had wrote down does not work. System restore fails because I can't it doesn't have a .DDL file or it says something. If I could get the USB 2.0 to work I have an external that has a couple of images that would be better than re-installing. I tried moving the image into the computer then using the image restore, but I learned that doesn't work because it somehow tracks were it wrote the image to. This is way I need the usb 2.0 to pull the image from my external HD.What is the default password of HomeGroupUser$?

I have a Windows 7 Pro x64 which has been running for a many months without any issues.Three days ago I restarted the machine and Windows 7 didn't start anymore. I have spent a lot of time investigating it and could not find anything wrong with the boot loader or the file system where the OS is.So the boot loader works, I have also replaced it just in case but nothing changed. I can go into the boot loader menu and chose the Windows 7 entry but then the black screen which says "Starting Windows" comes and nothing else happens.Note that the computer doesn't hang, it simply gets stuck at some point and doesn't do anything else. The HDD LED stays on from this point forward and that is it, if I press ctrl+alt+del it restarts and if it were completely frozen it wouldn't.
This Windows 7 runs on a pair of drives in RADI1 so it cannot be a problem with the drives. I have run checks just to be sure and couldn't find anything, no file system issues or bad blocks.The raid controller is not reporting any issues with the drives.I have booted with the windows install cd and tried to repair it many times but the auto repair says it could not repair it, other times it tells me that no issue was found.The boot manager is working fine, I have replaced it just in case using bootrec /fixmbr and /fixboot and also bootsect /nt60 all.I have checked for corrupt files with sfc and no files were corrupt, at least no critical system files.I have manually replaced the winload.exe file but this didn't help either.The problem seems to be at the stage where the boot manager passes control to winload.exe.

I am currently using windows 7 ultimate x64. I was in the middle of a process restoring my computer to a few days back and suddenly it froze. I did a power shut down and when I turned it back on, I wasn't able to get back into windows. I was brought to startup repair and it gave me errors. 'Boot manager failed to find OS loader'. There was options for restoring, but all my restore points were gone. Recovery wasn't able to find image backup.
"Startup repair cannot repair this computer automatically". I was told to go into safe mode to restore, but whenever I enter safe mode, startup repair would take over and shows the same errors, also I read a tutorial using a repair disc ( made a copy of it on someone elses ultimate x64 computer) and I get the 0x00000e9 error if i boot from disc. What can I do? As of now I don't have the installation disc with me. I wont be able to get hold of it until tomorrow. There's a lot of important files in that hard drive and I really cant lose any.

my copy of win 7 was getting increasingly ropey the other week (kept freezing etc.) but i was able to start it in safe mode. now it won't boot at all, when i try to start it form the hard disc it says 'loading files' with a white bar along the bottom which crawls up, i have left this for hours with no joy. when i try to reinstall it gets as far as letting me select the language and then just hangs with the busy mouse icon, again i have left for ages with no joy. so the OS seems to be corrupted and sadly i have files on the OS section of the disc (yes i know....backup!) which i need.
so i assume i somehow need to get another OS to work to back my stuff up and then format the hard disc.
i saw you can in theory run linux from a memory stick, enabling me to back the files up. running xp from a stick is another option which i tried but my laptop didn't seem to boot from it, despite being set to do so. i have another laptop, aswell as a device which can use a sata/ide hard disc as usb disc, could i maybe remove the hard disc and do this ?
it's an HP 625 laptop with windows 7 32-bit pro.

A couple weekends ago when I was using my laptop, I fell asleep and awoke to find that it had turned itself off. I rebooted it to find that after the BIOS screen, nothing happened: I just got a blank screen with a cursor. I have seen this thread but unlike the fellow there, I had no problems at all just doing a clean install from a USB drive, as I'd done the same only a week or two before and didn't exactly have much data to lose. The install went completely fine, including the two restarts required, right up to the "Welcome" screen after connecting to a network, upon which it went to "Shutting down", did so, and I was once again back where I'd started, with the blank screen and flashing, immobile cursor and nothing else.I've tried re-creating my bootable USB drive, and the sfc /scannow command in Windows Repair options wouldn't run, saying that I have a process already running that requires Windows to restart (which I can't do, and which doesn't go away even after yet another reinstall).I've tried reformatting and recreating the partition (I have just the one) before installing as well.The laptop is fairly old: a four-year old Acer Aspire:
2GB RAM
Pentium Core 2 Duo 2.0 GHz
Nvidia 7000 (256 MB)
All I know off the top of my head; will give more info if it's needed.Because I was able to install Windows 7 completely right up to the Welcome screen after which my desktop should have been prepared,I don't think this is a hard drive issue.When reinstalling Windows 7 on it,it recognized that Windows 7 was already on it and correctly gave me the size and space remaining on the drive.

About a month ago I had to reinstall Windows 7 Home Premium because it had the win64/sirefef virus. Security essentials would not work and neither would the windows firewall, etc.I have the virus again somehow, but this time when I try to boot it into safe mode and do a system restore or back up my files I can't - it says windows restore won't work and there is a critical error and will restart in 1 minute (this happened last time as well except not in safe mode and I was able to do the restore - but the critical error was occurring in regular mode). How do I backup my files (I have new files since the last time) and reinstall without the discs?

So, had to install XP beside Windows 7 64bit... Windows 7 64bit was installed while in BIOS hdd was set as AHCI.To install XP, I've to put it to IDE. Now if I put AHCI i can boot in Windows 7, but not in XP(BSOD), if I put IDE can't boot in Windows 7(BSOD), can in XP. Downloaded AHCI driver for my MB (MSI P55-GD55) and can't install them in XP, says no system requirements.What to do? Is there a way to boot with IDE to windows 7 64bit without reinstall?

I recently installed Windows 7 professional and had some problems with my first install, so I decided to reinstall. In the course of getting everything working on the the second install the Windows Boot Manager comes up everytime I turn on the computer.
It is very strange because: I have only Windows 7 installed on my computer and no other OS. The only selection is one instance of Windows 7 (I know sometimes when you reinstall the same OS will be listed twice, this is not the case for me) there is no countdown timer to automatically start windows. I have to press the enter key or it just stays there. Other than that, windows 7 is working fine for me. It is very annoying since I sometimes leave the computer after I turn it on and when I'm back it still is on the Boot Manager.
These are the things I have tried to get it working: I've went to msconfig-->Boot Tab and looked to see if there was a more than one OS listed. There is only one instance of Windows 7 listed. I went to my computer properties-->advanced system settings-->advanced and set the boot manager to not run, but it still comes up even after I change this setting I also tried reinstalling windows 7 twice. Once with just formatting the partition. Once with deleting the partition and recreating it before the install.

Problem description: Windows 7 fails to boot. I was playing a game when I was no longer to input anything (kb/mouse stopped working) although animations and sound continued. I restarted and the windows 7 animation appears, plays for awhile then freezes. I can start in safemode but that's it. Attempting to run the recovery tool gives me a "windows loading" screen then goes to a black screen. On my initial install of windows 7 on a brand new HD a week ago I had no problems getting it up and running.
Attempted fixes: System restore. Last good configuration. Uninstall video drivers. I tried doing a new install but all having the DVD in does is give me "loading windows" screen prior to freezing at the windows 7 animation. I tried putting in a vista disk and I get a similar problem, it hangs at the loading windows animated bar, but without the logo. I even tried putting in a brand new HD and disconnecting the old one and it STILL starts trying to load windows 7 (with the install dvd in), and it will still freeze with the vista disk in.

I have a laptop that came with windows 7 installed. It has single hard drive which I have sectioned into c drive and d drive. I have made this laptop dual boot with windows 7 which was already installed and server 2008r2. My server 2008r2 copy is about to expire.So I will have to reinstall the server 2008r2. I am little confused because when I log onto server 2008r2, the C drive becomes the drive where windows(server2008r2) is installed. And similarly when I boot into windows 7 then c drive becomes where windows(windows 7) is installed. So if I were to keep windows 7 intact and reinstall server 2008r2 then,what exact steps will I have to follow to just reinstall a fresh copy of server 2008r2 trial valid again for 6 months? Please guide me. I am totally confused and dont know how to do it.I have important data on laptop so don't want to loose it.

6 months ago I installed windows 7 on a new PC I built. I then decided to switch to a 64 bit system which I did. I bought another HDD and decide to add a second drive with windows XP.I ended up with a system which had windows 7 shown twice on boot up and only one would bring up windows 7. Windows XP was missing. I removed the second drive and it worked fine but I still had 2 Win 7 prompts on boot up.I have a virus or root kit which I can't find or remove so I decided to format the C partition and reload windows 7. The problem is although I have the bios set to boot from the cd with the Win 7 disk, it comes up with the boot manager missing message and I can't get around this.I tried another HDD and get the same message. How do I get rid of this problem where i can re install win 7?

I recently got a new ssd and installed Windows 7 on it (I used the oem code on the bottom of my laptop [Lenovo Y580] along with the iso from digitalriver). It's been... well, as good as you can expect windows to be up until yesterday. When I booted the laptop into Windows, I had no internet despite having an ethernet cable connected. I checked to make sure it wasn't just my router. Sure enough, wifi and ethernet work perfectly in Ubuntu. I went into windows again and checked if I had the latest drivers. I did, so I tried reinstalling them and everything worked fine. Until I restarted. Every single time I restart I need to reinstall my wifi and ethernet drivers. It takes seconds, but it's still annoying and shouldn't be happening.

I used to have Windows 7 which works flawlessly... I used to have linux Mint 11 dual booting with Windows 7, I recently upgraded to Linux Mint 12 and from that upgrade I cannot see the windows 7 option in the boot menu.. I tried to reinstall the boot loader of windows 7 from the Windows 7 CD but when I press "Repair Your Computer" then it does not show any operating system existing on my computer... install the boot menu in the MBR again.

I have an HP G62 laptop which came pre-installed with Windows 7. I would like to fully remove all data on the HDD and reinstall Windows 7.The 'Computer' section of the Start button shows the following HDD (not sure if these are partitions or not, but I'm assuming that they are!):
Local Disk ( C: )
Recovery ( D: )
HP_TOOLS ( F: )
I had a quick look at the D: drive and it showed a few setup files, all of which seem to be related to MSOFFICE. :-?I have been reading about data destruction programs that will absolutely wipe the drive and remove all data; I would like to do this and then reinstall Windows 7 so that the laptop effectively becomes a 'new' one.
1. How do I go about formatting the HDD with a data destruction program and then reinstall Win 7, since I do not have a bootable disc?
2. How reliable are such data destruction programs? Is there any margin of error? (I am a bit concerned about all the sensitive information that I have saved on my laptop such as bank details, family photos, etc.)
