Bootmgr problem - can't boot windows

Hi.
Please help me with my boot problem. I cannot access my computer, windows will not boot.
I am running windows 7.
Upon starting up my laptop, I get the message "bootmgr is compressed - press ctrl alt del to restart"
I have searched for the problem around the internet, and it seems to be due to people compressing their hard drive to save space and cancelling half way through.
I have not done this- I was playing around with a SLIC Loader program and installed it by mistake, now I can't boot windows.
I have tried using my windows 7 DVD to repair the startup but it didn't work.
I have also tried to restore but I did not set any restore points.
I have tried using some command prompt bootmgr reset procedures which also did not work.
Can I somehow get a backup of bootmgr and restore it?
Please help
Thanks

Hi
I assume your boot manager is damage. Probably by installing the SLIC Loader program
My idea was simply; boot from Win 7 disk and then try to get into the command console.
There you could use the command FIXMBR
But if this will not help then you should take your Windows disk or Toshiba recovery disk and should reinstall the whole system again.

HT4818 I have installed bootcamp that worked properly. Then I have partitioned the OS X 10.8.2 and installed another OS X 10.8.2 and I have got two MAC boot options and Bootcamp disappeared from the Option menu. How can I boot Windows again and keep both

I have installed bootcamp by the bootcamp assistant and worked properly.
Then I have partitioned the OS X 10.8.2 and installed another Mountain Lion System and I have got two MAC boot options and Bootcamp disappeared from the Option menu. However, Bootcamp still remained in the Startup Disk in the System Preferences. When I tried to boot Bootcamp using the Startup Disk it did not boot and received a message that there is no bootable device. I have not lost any data and can read Bootcamp partition from both OS X systems. Please advise how can I boot Windows / Bootcamp again? Thank you.

Recommendation 1: Use a VM for this. It's essentially a giant C.F. to do this with native booting, and is potentially fragile.
But if you're going to ignore that and do this anyway, realizing that it can break anytime in particular with OS upgrades, and that it's very difficult to impossible to resize the three volumes once you've installed the systems:
1. create three partitions, setting each to be the size for OS X copy 1, copy 2, and Windows respectively. The Windows partition needs to be set to MS-DOS format (actually FAT32) which later in the Windows installer you'll reformat as NTFS. Do not use Boot Camp Assistant to resize/partition the disk, it simply won't work for this use case.
2. install OS X copy 1
3. install OS X copy 3
4. Use gdisk (available at sourceforge) which is a command line only application, to create a new hybrid MBR adding only the last partition (Windows) to the hybrid MBR and setting it to be bootable. As a concequence you will not be able to see/share either OS X volume from within Windows. The Windows NTFS volume will be visible from within OS X.
5. Install Windows to the only partition its installer should see (confirm size), you'll need to format it NTFS first, and I suggest using the fast format option if available.

I can't boot windows in my iMac late 2011 as my internal cd reader does not work

i can't boot windows in my iMac late 2011 as my internal cd reader does not work

Which copy or version of Windows? and how where was it purchased?
my window installed itself perfectly on another computer.
One copy and you want to activate on two computers?
With 16GB, it will try to create 16GB hibernation file, 24GB page file, and need 20-30GB for the OS, plus room for temp, cache, applications, 9GB just temp to install SP1 update(s).
did you create 80GB or larger partition?
also, some macs with ssd + hard drive have issues, and of course you need Windows 7 64-bit home premium (Pro to use more).
OWC has up to 32GB, not cheap.

[SOLVED] Can't boot Windows 8 using grub2. invalid EFI file path

English is not my native language. Please excuse typing errors.
I have just successfully installed Arch linux with grub2 as its boot manager. I
followed the arch beginner guide. I've used grub before and I'm familiar with
it, so chose to use grub instead for efistub. I installed os-prober and
ran grub-mkconfig to create the grub.cfg file. The problem now is that I recieve
an error when I try to boot windows 8. I have two drives (/dev/sda and /dev/sdb)
and I believe both are EFI-systems.
However, it's not very important for me to use grub, so if booting into windows
8 is easier using efistub, I will try that.
The computer is ASUS ux32vd with a hybrid disk with 25GB on the SSD and 500GB on
the hard drive. I believe the SSD part is used by Windows.
This is the first error I recieved when I tried to boot windows.
error: can't find command `drivemap'.
error: invalid EFI file path.
Press any key to continue...
Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:
error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found
Press any key to continue...
Here are some command line outputs.

I gave up trying to make grub work, so I uninstalled grub and deleted all the grub files I could find.
# pacrem grub-efi-x86_64
# rm -fr /boot/grub
That last one I came to regret later on. So I installed rEFInd using the archlinux beginners guide. When I then tried to boot into windows It told me that /boot/grub/x86_64-efi/normal.mod was not found. I then reinstalled grub-efi-x86_64 and copied /usr/lib/grub/x86_64 to /boot/grub. Now everything works fine.

The EFI stub loader is a Linux-only boot loader; however, it is possible to use the EFI stub loader in conjunction with a separate boot manager, such as rEFInd or gummiboot. In such a configuration, you'd use the boot manager to select the OS to boot (Windows or Linux, and possibly the specific Linux kernel), and the boot loader (the Windows loader or the EFI stub loader built into a specific kernel) will then take over booting the OS. In Arch, this is often easier to configure than is GRUB, since GRUB is very complex and its automated tools to help with setting things up often get it wrong.
This is the first error I recieved when I tried to boot windows.
error: can't find command `drivemap'.
error: invalid EFI file path.
Press any key to continue...
The "drivemap" command in GRUB is generally used when booting a BIOS-mode boot loader, and in fact your "Windows Recovery Environment (loader) (on /dev/sda2)" and "Windows 8 (loader) (on /dev/sda4)" GRUB entries are both built as for BIOS-mode Windows installations -- but the fact that your disks both use GPT means that Windows won't boot in BIOS mode on your computer. (This is one of the many things that the GRUB setup scripts can get wrong.)
Then I tried to follow this post
https://bbs.archlinux.org/viewtopic.php?id=150183 and made a new boot
entry "Windows 82". And I got a new error:
error: unspecified search type.
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found
Press any key to continue...
Both your "Windows 8" and "Windows 82" entries refer to an EFI boot loader file called EFI/Microsoft/Boot/bootmgfw.efi on your EFI System Partition (ESP). This should be correct, but your Boot Info Script output doesn't show any evidence of such a file. Sometimes Boot Info Script misses such things, so you may want to check it just to be sure. Your ESP is /dev/sda1, and it looks like it's being mounted at /boot/efi by default, so check for the /boot/efi/EFI/Microsoft directory tree, and for /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi in particular. If that file isn't present, then something is wrong -- perhaps you mistakenly erased the ESP when you installed Linux, thus wiping out the Windows boot loader; or perhaps the file was accidentally deleted somewhere along the way. (Note that on FAT, which the ESP uses, case is irrelevant, and in fact case varies between the filenames reported by Boot Info Script and what's recorded in your configuration files.)
You do have another boot loader file that may be a duplicate of the Windows boot loader: EFI/BOOT/bkpbootx64.efi. This filename is generally created by Ubuntu's "Boot Repair" tool, which IMHO can do as much harm as good, especially on a system that's not booting Ubuntu. If you ran this tool, though, it's conceivable that bkpbootx64.efi is a copy of the Windows boot loader, so copying it to EFI/Microsoft/Boot/bootmgfw.efi might get things working. OTOH, the Windows boot loader relies on other files to do its job, so if they're not present, copying the Windows boot loader to its original location won't be sufficient.
If you can't get things working based on the preceding suggestions, I recommend you run a Windows repair tool. These are accessible from a Windows recovery disc. Such disc images are readily available on the Internet, but I don't happen to have any links handy. Try Microsoft's own site; images obtained from random third-party sites might contain malware. Once you've done this, chances are the computer will boot directly into Windows. You'll then need to either restore GRUB as the default boot loader or install another boot loader or boot manager. You can use the Windows "bcdedit" command to do the former, as in:
bcdedit /set {bootmgr} path \EFI\arch-grub\grubx64.efi
You'll need to type this from an Administrator Command Prompt window.

My iMac can't boot Windows 7 From USB while my Macbook Pro can do it

I install Windows 7 64 bit and rEFIt into a USB hard disk and hope to boot from my iMac 27" (2010 Mid). However, it shows that no boot deivce is found.
If I plug the SAME disk to my Macbook Pro 17" (2009 Mid), it can boot Windows 7 without any problem.
I tried with Linux and get same result, iMac says no boot device while my Macbook Pro can boot it without problem.
I tried experiment for weeks and still can't get iMac work.
I think it is very abnormal and I wonder if someone can tell me how to fix it or any directory to solve this problem.

My iMac runs snow leopard and my MacBook pro runs Lion. Both of them are updated with latest updated. I just get one external USB hard disk with Windows 7 32 bit installed and magically, my iMac can boot it from rEFIt. However, I don't know what makes it works. I tried to make same configuration, software and steps on other USB hard disks for hundreds times but I can repeat it again. All other attempt can make USB hard disk boot on MacBook Pro but not iMac only.

Mac OS drives no longer visible, can only boot windows.

I have 4 internal drives and 1 external drive on my Mac Pro. Three drives are Mac OS, on internal drive is XP, and one is Win 7. At the moment I can only boot from the Windows drives. The Mac drives are not visible from boot camp or at startup holding the option button down. I know the cause, but I dont know how to fix it.
I caused the problem while booted into Win 7. I was trying to install VS2010 beta 2. The program failed to install, and I found out the problem was that the installer was trying to access the Mac disks. I removed the drive numbers from the 3 Mac disks, and the installation worked. After I relettered the disks I was able to see them from Win 7 (not XP).
I assume I somehow messed up bootcamp. I have no idea of how to fix this. I would appreciate any help.

We have a BootCamp forum.
Do any of the drives show up in Disk Utility?
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.

Can't boot Windows 8.1 using refind

Hello,
I just installed arch on my computer that has an existing installation of windows 8.1 and am having trouble booting windows using refind.
I've configured refind so that arch loads fine and windows should be autodetected from what I've read, but it isn't. So I tried adding a manual entry for windows but that isn't working either. I think the problem is that windows is installed onto another drive and refind is having trouble seeing it. It may be that I don't have a refind driver for ntfs partitions, but I couldn't find one. Any help would be greatly appreciated. Let me know if I left anything out.
Here's the relevant info from refind.conf
I did try changing the path to the windows loader to have a leading '\' and also to point to bootmgr.efi instead of bootmgfw.efi
menuentry "Windows 8" {

It is best to share ESP with windows and mount it on /boot.
If you didn't then do this
# mkdir /tmp/ESP && mount /dev/sdb1 /tmp/ESP
# find /tmp/ESP -iname bootmgfw.efi
If you want the things going smoothly, consider to mount win8 ESP in Arch /boot and make sure that the old /boot content is copied into the new location. You should need to install the package dosfstools, if not available.

Problem with dual booting Windows 7

Hi!
I've been running Arch for some time now on my laptop, and wanted to get it going on my desktop computer, which was (is) running Windows 7. I followed the guide on the wiki and searched for the problems that occured, but didn't make any progress. After installing grub2 and running the grub-mkconfig. This is how my grub.cfg looks like now:

I'm quite new to this stuff, but when I'm trying to boot Windows 7, it comes back with this:
error: invalid signature
I've tried various different things. Sometimes the error above returns, and sometimes this:
BOOTMGR is missing
Any help is appriciated!

Rydberg95 wrote:
I have os-prober installed and when I run it this returns:
No volume groups found
However, it didn't return this a few hours ago when I ran it in the grub-mkconfig. Back then it return some stuff about the file formats (mostly ext4 and ntfs) and that there was some kind of error with those.
Could be wrong, but I suspect you are using dynamic volumes in Windows 7 (check in Windows: Control Panel > Administrative Tools > Computer Management > Disc Management for current volume type). You probably need to convert to basic disc type in Windows 7. I had to do this once to be able to install Fedora. Unfortunately this is not a trivial undertaking.

I have Win. XP Pro, can't boot windows, no recovery / reimages, Win. repair can't fix, need prompts

I inadvertly used the disk sanitizer on my laptop and now I cannot boot Windows or anything else. I do not have any system images, or recovery disks as this PC was given to me I have used a repair disk from my HP Pavilion Windows 7, which does get me as far as system recovery options. The system repair cannot fix the problem and sends me to HP recovery manager the only option I am permitted to choose is run computer checkup, when I click on this it asks me to open a command prompt. Can anyone walk me through what prompts to use? I have tried and sfc/SCANNOW and it says that I have a scan pending which requires reboot to complete. I cannot start Windows. I do have a license for Windows XP pro, but I do not havde the installation disk. Any help would be great.

Thanks for the replys. After much gnashing of teeth I realised the problem was my keyboard wasn't working in BIOS and eventually remembed I had switched my mouse from the PS/2 slot to a USB port. Switching back solved everything.
I suppose future 'legacy free" PC's will have to install usb drivers in the BIOS. Thaks again!

NOT as a cache, can i boot Windows 8 directly from MSATA 128gb on an Envy 4 1026tu..?

Can i install & boot Windows 8 directly from MSATA 128gb on an Envy 4 1026tu..? Not as a cache. I want to keep my existing HDD as extra storage. Can i clean install Windows 8 and boot directly from a 128gb MSATA on my Envy 4 1026tu? Could anyone please advise me if this could be done. Thanks!

Hi,
In theory nothing can stop you to do that. You have to disable the HDD before install OS on the mSATA. One important thing: The BIOS allows you to do that. I know Dell people have done that. At the mean time, the following article may help:

Good luck.
ps My HP machine has only 32Gb and inaccessible.

Can't boot windows. Stuck at Welcome/login

Hello!
I recently purchased a macbook pro retina, mainly for music production but also for some other stuff.
Now the thing is that the music production software that i'm using, does only work with pc. So i decided to
bootcamp my mac so that i can use it as a pc.
So far everything has gone as planned. I can now operate windows 7 on my mac and the Music Software (FL Studio 10)
works as a charm.
It was just recently when i tried to install my external Sound drive (Audiobox USB) that i was experiencing some problems
with the audio. So i googled about the issue and somewhere i read that it could possibly have to do with the USB drivers being out of date.
So i checked the device manager to see the who the developer of the usb drive is (to find updates) ect.
Now when i've found the updates, i try to uninstall the previous USB devices that i have so that i can install the new ones. But somewhere in between uninstalling and installing the new drivers, the computer suddenly freezes. I try to reboot normally and in safe mode,
but when i come to the windows log in screen, i can't type or move my mouse.
I'm not very bright when it comes to computers (especially macs), but after giving it some thought i think that i might have caused an error since i kinda forgot i was operating on a macbook and not Pc. I mean, when using bootcamp you get the "apple drivers for windows" download and that's probably where i should have gone in the first place, to look for updates. Now instead i have tried to manually take away the usb drivers and install the
updates from Intels website.
Someone suggested that i might have uninstalled the Bootcamp usb drivers accidentaly, which i think is true. But if download the "Bootcamp install/repair drivers setup (which will restore all my drivers to normal) and place it on my usb flashdrive, how am i supposed to open the Usb flashdrive when i can't even get past my login screen?
Is there a way to solve this without having to start over and uninstall/install bootcamp from scratch?
Best regards
Fidelix

Can't boot Windows properly

Hi!
I got some new parts for my comp about 1 week ago. I have been running this system stable for a few days when suddenly the computer wouldn't boot windows properly! It enters the Windows loading screen and then nothing happens.
After like 10 restarts i can enter windows again.
Safe mode with networking works perfectly and the windows has a clean install.
I have tried to boot with only 1 mem-module, then i tried some different sets and i tried to increase the voltage as well on both CPU and memory but no difference whatsoever.
I am not overclocking although i tried overclocking with the built-in system for overclocking but got a bluescreen so i set it back.
When i am in windows, working or gaming then everything runs smooth and i experience no strange things at all.
Please help, this is getting really frustrating...

Yes i have tried both the system restore, full system virus scan, scan for spyware and stuff, and the choice before the safe mode with networking, no difference there :(
As of now, i uninstalled my graphics driver (Catalyst) and rebooted a few times, and it reboots. I reinstalled the graphicsdriver but only the driver and not the catalyst center and it rebooted properly. this doesn't make any sense at all to me. Do you think my PSU is powerful enough?

Can't boot windows after creating new MS-DOS (FAT) partition

I created a new MS-DOS (FAT) partition on Yosemite, and now I am unable to access my windows bootcamp partition.
- I can attempt to boot into windows from Yosemite however after a long while, I am prompted with "no bootable device".
- The option to boot windows from the startup manager is no longer visible.

It still shows the bootcamp partition with windows.
EDIT: Creating the new FAT partition did seem to create another partition which is visible when looking at the partition layout; the other partition is 1.04gb; format "Free Space". Apparently that's from bootcamp - hadn't noticed before.
I took some screens to show what I mean ("WINDOWS EXT" is the new partition I created):

Msi p55-gd65 problem, can't boot

Hello, yesterday i have tried change graphic card to gtx 480, and after that PC can't boot, even if i have changed to old graphic card. Tried other psu, other graphic, put off bios battery and didnt help.
Here is a video what is going on: http://dl.dropbox.com/u/7243958/Wideo0020.3gp

Quote from: Bernhard on 03-March-12, 21:31:17
Well lets trace back the steps. It started happening at the time you added the 480.
I don't want to be a pessimist, but there is the possibility that an overload on the PSU may have caused a problem on the 12V circuit of the PSU causing other damage on the 12V board input circuits.
but how motherboard could be damaged, this psu ocz fatal1ty 550w is about 1,5 year old, and its sufficient to turn on it gtx 480, even pc didn't turn on when i changed on gtx 480.

Can't boot Windows 8 recovery CD via USB! (X1C)

Hi,
I can't boot the windows 8 recovery CD Lenovo sent me via a USB CD drive.
I've used all the combinations of legacy, secure boot and others etc. Am I missing something obvious?
When I boot it shows the boot menu with the CD drive as first piriority and I press enter to select and boot from this device however it just refreshes the screen and goes back to the boot menu straigh away... ??
How the hell can I recover my laptop?
J.

Solved it by using an external CD drive plugged into USB port. By the way anyone contemplating using Lenovo Recovery disks for Vista operating system re-installation, note that the Wireless drivers do not get re-installed. I had to download these after from the Lenovo support site. The whole process took a day to complete.
