Windows 7/Ubuntu 10.10 dual boot issue

November 14, 2010 at 15:16:05
Specs: Windows 7/Ubuntu 10.10, Dual Core/3 GB ram
After installing Ubuntu 10.10, I lost my Windows boot menu. The Grub2 menu works fine for loading Ubuntu but it will not load my Windows 7 install. I do not believe that it is a Grub issue, seeing as I can boot Windows from Hiren's Boot CD. There is an option on the boot disk to "boot Windows Vista/7 (bootmgr)" that does the trick loading Windows. It is a major hassle to boot from the CD everytime. Also, note that when I boot off the disk, it does bring up my Windows 7 boot menu. This menu is able to boot both Ubuntu and Windows 7...How can I get this menu to display without booting from the disc?

I'm using Grub2 so the file is Grub.cfg but yes, Windows 7 is displayed there and it does show up on the menu. However, when I select it on the Grub2 menu, all it does is display a blinking cursor in the top left of the screen.

Thanks for the help. No that doesn't seem to apply. I have a feeling that there is an issue with my Windows 7 boot process. I can boot it, but I need to use a CD to do it. Also, I uninstalled Grub and tried to restore the MBR and when I attempted to boot up, the computer diplayed the initial BIOS splash screen and then displayed two smiley face characters and the blinking cursor in the top left cursor. I am totally befuddled...

hmmm I've never seen that one before. I have my laptop dual booted with Fedora and Windows 7 and I remember having a similar problem. But I don't remember doing anything other than editing the grub config. Sorry.

Should have used the built in WUBI installer.

Try this:

EasyBCD 2.0.2

try mount command to see what linux sees as the windows device.

Wubi may or may not have helped. It could be that your install has the system files on a drive and they are pointing to some other drive or array. This is usually the case where ubuntu and others fail. If you had reloaded or some odd upgrades or installed a raid array this can happen.

Why did it take me over a year to phone in a problem to ATT?

Have you tried using the Windows disk "Start up repair" option?

Check this out http://support.microsoft.com/kb/927... I followed those steps with the bootrec.exe /fixmbr option and it solved all of my problems. Hopefully this helps you out!

I've been struggling in a similar area, but here's my take. Because once you reached the Win7 boot menu either OS would load, I would say the Win7 BCD is good. The problem then is in the mbr.

How did you try to restore the mbr? I would try from a Win7 repair disk (eg, see: technet . Then, once up again, if the BCD didn't offer both Win7 and ubuntu, from Win7 I would use EasyBCD to set that right.
