Cant Boot Windows, Linux Boot Loader Has Taken Over
Nov 13, 2009I 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?
Boot Loader Is Missing
May 1, 2011I 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.

Sep 8, 2011I 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?
Lost Boot Loader / Bcd Entirely?
Jul 6, 2010I'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:
Reinstall Windows 7 Boot Loader?
Jan 24, 2011I 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?

View 3 Replies View RelatedInstall Via Mounting But Don't Want Boot Loader
Jul 25, 2009Is 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.
Windows 7 Boot Loader Recovery
Nov 1, 2012I 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

Aug 29, 2010My laptop apparently is having a hard time booting.

Oct 9, 2009I 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?

Jun 6, 2011All 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$?
View 3 Replies View RelatedBlack Screen After Boot Loader, Pressing F8 Doesn't Do Anything
Jul 25, 2012I 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.
Windows 7 Installed-how To Setup Partitions/boot Loader To Install Linux On Second Hdd
Nov 11, 2011I 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)

Oct 5, 2011I 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.

Feb 9, 2013I have done some looking around and have found lots of mentions of the same issue but people tend to skip through some of the in between key steps as they are working on their own computers and not trying to do this blind.
I had no idea at first what she'd done but apparently this is a common problem. Basically, if a netbook's battery goes dead while it is hibernating then it creates a problem when the user reboots. The machine gets to the windows resume loader page and then freezes there. It offers you a choice but the keyboard is unresponsive. I got her to force quit and restart but same thing.
I found that many were able to use a PS2 keyboard to work around this but my mom does not have one. She doesn't have a start up disc or anything like that.
I found this solution elsewhere but as you see, the guy skips the key steps: Hopefully your computer gives you the opportunity to visit you bios settings/ peripherals. You can usually access this at the very beginning of startup by following the prompts such as "F1, F9, DEL, TAB, "....etc. I am pretty sure that each Motherboard has a different setup. Once I found My way to the peripherals I was able to scroll down to "USB keyboard" and saw that it was disabled. I enabled it, saved those settings and continued on to the "RESUME LOADER" page that had not been responsive before and Ta-Da!!!! it worked.
So, I need the easiest, most explainable steps to follow so I can walk my mom through them. It is the f8 key you press upon startup to get to get to safemode? Or does this guy mean to actually press F1 then F9 and so on?
manually enable the keyboard on her netbook and get past this.
