MBR helper missing

[ahadmobeen_1]

I was using vista and ubuntu with dual boot option, due to improper shut down my vista crashed and I reinstalled it. but system was not booting from vista, then I used the repair commands of vista bootrec.exe/fixmbr etc and vista started to work, then I installed ubuntu to make dual boot but when I boot from ubuntu it gives mbr helper missing error, but vista is working perfectly. I have formatted the complete hard disk considering it a partition table error but still not working. even only ubuntu cannot be installed
Please tell me the fix to this problem.

hi and welcome to the community,

was this a wubi install (ubuntu in windows)?

Boot into Windows, run chkdsk /r from Windows on the same drive where you have installed Ubuntu, shutdown cleanly and then try to boot into Ubuntu again. Post any error messages verbatim.

You may need to reinstall grub(2) if not a wubi install.

Open Zip:

Win>Testdisk_win

then go to:

No Log>(select drive)>Intel/PC partition(unless you got something different)>MBR code>Write new copy: Y > few more yes's> Then reboot


This will work without your windows recovery CD... I suggest you save this Tutorial.. :)

Took a whole day to find it for me....

I dont know this has worked but when I used it my Vista and ubuntu both get corrupted, some errors like

cannot found system32/windows/winloader.exe

were displayed on both ubuntu and vista for ubuntu it was showing ubuntu drive's path, then I installed vista and then installed ubuntu using grub and it's done.

Thanks everyone for help but install inside windows (wbui) is still not solved.

Still giving same error when i install it inside windows

have you tried another copy of the ubuntu livecd? i think you have a faulty cd.
download the iso from the website: http://releases.ubuntu.com/
check the md5sum after downloading, then burn the image at a low speed (at max.10x) and check the md5sum of the burned cd.
then try booting off the newly burned cd.

I have a similar problem. Waiting for a solution. Please share details if you were able to solve this problem.

this is an old thread and boot problems are often unique. If the solution is not in this thread, it would be better for you to start your own thread.

Two things.
Many have upgraded and installed grub into the windows partiton.
Fix for most, a few have other issues, better than windows fix in many cases as it also fixes other parameters:
This has instructions on using testdisk to repair the install of grub to the boot sector for windows from Ubuntu or Linux LiveCD.

IF that does not work, in your new thread post this:
