How to remove Phantom Ubuntu OS option in boot menu

commonbill · 09-10-2010, 05:02 PM

Originaly I had Win7 and Ubuntu (Ub) set up OK in dual boot. The Ub was on a seperate drive in its own partition - then the darn drive failed. Without reinstalling Uu I still get it as an option in the dual boot menu. If I do reinstall Ub I end up with a 2nd Ub option. How can I get the boot menu to show Win7 only, so that I can re-install Ub with only 1 entry in the boot table?
I have tried using bootrec.exe from the command line in Win7 recovery mode but that does not fix things.

Not sure what you talk about. Which boot loader are you using? I presume a linux bootloader, ie. grub.

When you have Ubuntu setup you can easily updated the entries for grub in (something like: ) /boot/grub/grub.cfg or /boot/grub/menu.lst (this is for grub 1.) You can edit this file and use the configurations you like.

In this file you should see every bootable configuration for the system, ie. a common ubuntu boot option, windows 7, and (probably ) a failover conifg for ubuntu.

How many physical hard drives do you have now?

Use your Ubuntu install CD, load it and open a terminal and run the command: sudo fdisk -l (lower case Letter L) and post that partition information here.

I think what he is saying. He did the install inside windows and it wrote to the windows MBR. So when the drive failed windows is giving him the option to boot ubuntu. Thats the problem I have on my wifes computer anyways I neverr figured out how to get it to go away so I never do ubuntu installs inside windows again.

Just to add you might be able to remove it by booting with your windows cd and select windows recover. select windows and type your admin password in and then type fixmbr .

I haven't tested it yet so use it at your own risk. Be sure to back you windows files up

The problem as one reply figured out was that Ubuntu installed as a guest of Windows7 then the volume with Ubuntu failed.

Solution was found on web by downloading a utility called EasyBCD which allowed me to clear the boot menu.

I tried to install Ubuntu after that and the menu worked fine but Ub failed to finish installing. On the requested restart it hangs up.

That's a new thread to be entered since the 2 subjects are different.
