Run partition magic again but make the partition table that has your operating system in it as the active one.

I've never used part magic but I have used linux GParted live cd, and Hirens boot cd.

Windows 8.1 x64 dvd won't boot on UEFI pre-installed Ubuntu laptop


not sure on this one Ubuntu likes to be installed last after windows is set up. I would think that you would have to blow away the ubuntu partitions by resizing the partitions to one partion. But you would want to be extremely careful not to touch the hidden recovery partition. You could use a program called gparted to see what the partions are and resize the partion. Extreme caution is needed as if you get it wrong you will not be able to undo it. The problem you are experiencing is because the boot loader is ubuntu grub. You will need another computer to download a gparted iso file and then use infrarecorder to make a boot cd. it can be found at http://gparted.org/ see http://www.ehow.com/how_6540931_remove-ubuntu.html

BOOTMGR is missing,


  1. Restart the PC. The BOOTMGR error could be a fluke.
  2. Check your optical drives, USB Ports, and floppy drives for media. Often times, the "BOOTMGR is Missing" error will appear if your PC is trying to boot to a non-bootable disc, external drive, or floppy disk.


  3. Reseat all internal data and power cables. BOOTMGR error messages could be caused by unplugged, loose, or malfunctioning power or controller cables.

    Try replacing the PATA or SATA cable if you suspect it might be faulty.
  4. Perform a Startup Repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR.

    Even though a Startup Repair is a common solution for BOOTMGR problems, don't worry if it doesn't fix your problem. Just continue troubleshooting - something will work.
  5. Write a new partition boot sector to the Windows system partition to correct any possible corruption, configuration problem, or other damage.

    The partition boot sector is an important piece in the boot process so if there's any issue with it, you'll see problems like "BOOTMGR is Missing" errors.
  6. Rebuild the Boot Configuration Data (BCD). Similar to the partition boot sector, a corrupted or incorrectly configured BCD could cause BOOTMGR error messages.

    Important: The following troubleshooting steps are much less likely to help fix your BOOTMGR problem. If you've skipped any of the above ideas then you may have overlooked a very likely solution to this problem!
  7. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors.
    Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.
  8. Perform a clean installation of Windows. This type of installation will completely remove Windows from your PC and install it again from scratch. While this will almost certainly resolve any BOOTMGR errors, it's a time consuming process due to the fact that all of your data must be backed up and then later restored.

    If you can't gain access to your files to back them up, please understand that you will lose them all if you continue with a clean installation of Windows!
  9. Replace the hard drive and then install a new copy of Windows. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.

BOOTMGR IS COMPRESSED


Validate and Fix the File System
This runs the check disk program to detect and attempt to repair problems on one partition. For example, to repair the C: drive:
At the prompt type chkdsk c: /r
Repair the Boot Process
Typically this is used if Windows doesn't start and you can't get to the safe mode menu. You might also replace the Master Boot Record (MBR) and boot sector if you suspect a virus infection. There are four options:
New MBR - Insert a new generic MBR without changing the partition table.
At the prompt, type: bootrec /FixMbr
New Boot Sector - Insert a new Windows 7/Vista compatible boot sector. It will automatically insert the right type of sector for the file system type (NTFS, FAT32, etc.)
At the prompt, type: bootrec /FixBoot Rebuild BCD - Rebuild the Boot Configuration Data (BCD). The BCD controls which partition boots. This option will let you select which installations to include in the BCD.
At the prompt, type: bootrec /RebuildBcd Find OSes - Scan the system for all OS installations that are compatible with Vista/2008 and will also show those that are currently included in the BCD.
At the prompt, type: bootrec /ScanOs
in the end type in C:/expand bootmgr temp

Got acer aspire 5535 laptop it is comming up ''BootMGR missing press ctrl alt delete'' have tried this no success


Boot off the Windows Vista DVD and then click Next at the first prompt:
image16.pngYou should see a link in the lower left-hand side for “Repair your computer”
image17.pngThe installation process will attempt to find your Vista installation directory. If there’s more than one in the list, select the correct one and then use the Next button again.
image18.pngClick the first link for “Startup Repair”
image19.pngThe installation process will repair the system, and then prompt for you to reboot.
image20.pngAlternatively you could have chosen the Command Prompt option instead, and use the following command to fix the boot options only:
bootrec /fixboot
image21.pngAt this point you should be able to reboot your computer, remove the DVD and everything should be working. If not, then head over to our forums and ask your question there. We’ve got some top-notch geeks over there!

No internal hard disk found


Hi there.
Use the Vista CD to create the new partition, but first you have to delete the old partition first, (the 220GB partition not the 10GB one because that will be the recovery partition).
Get a calculator and work out your new partition, for example 50GB is 50x1024MB so that will be 51200MB.
When you have deleted the 220GB partition select NEW and input your newly worked out partition and carry on from there, to activate the other partition just format it.

Please post back with the results and for anymore help if needed.

Good luck and thanks for using FixYa!!

If you do not want to loose data, You will need a Vista installation DVD to resolve this issue. You may borrow it from someone.

Following are the steps:


Method 1:

1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Startup Repair.
7. Restart the computer.

6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec /RebuildBcd, and then press ENTER.� If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type Yes. A confirmation message appears that indicates the entry was added successfully.
� If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.
Bcdedit /export C:\BCD_Backup
ren c:\boot\bcd bcd.old
Bootrec /rebuildbcd
8. Restart the computer.


Method 3:
Rebuild the BCD store manually by using the Bcdedit.exe tool

1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type the following command, and then press ENTER:
cd /d Partition:\Windows\System32
Note Partition represents the letter of the partition on which Windows Vista is installed. Typically, this is partition C.
8. Type the following command, and then press ENTER:
bcdedit /enum all

bcdedit -create {bootmgr} -d 'Description'
Note Description represents the description for the new entry.
10. Type the following command, and then press ENTER:
bcdedit -set {bootmgr} device partition=Partition:

bcdedit /default {GUID}
Note GUID represents the GUID that you obtained in step 8.
13. Type the following command, and then press ENTER:
bcdedit /timeout Value

14. Restart the computer.

The master boot record maybe be corrupted or virus infected.
To fix the MBR, boot up with your DOS disk and type fdisk /mbr
Then install XP, and delete all partitions and then create a new partition, then do a full NTFS format on the new partition.
