Windows 7: Dual-boot: Windows 7 & Ubuntu - problem

Dual-boot: Windows 7 & Ubuntu - problem

I installed Ubuntu 10.04 earlier today.

I have 6 HDs, and I installed Ubuntu on a 400GB partition on one of my REGULAR HD'S. My Windows installation is on my SSD.

Now, when I turn on my computer my Windows bootloader is showing, not GRUB. And if I press the "Start Windows Nornally" option - my Ubuntu boots. How do I fix this ?

I tried to repair my startup (using the Windows CD) without luck.

Thanks in advance!

Did you unplug the SSD when installing Ubuntu?

Please post a screenie of windows disk management - not clear if you can get into it.

If not post a screenie from within Linux.

Also - how did you install Linux - where did you tell it to install grub?

Ssd was plugged in, and I cannot boot into Windows, only Ubuntu.

The cleanest way to Dual Boot with separate HD's is via the BIOS.

Unplug the one OS HD while you install the other HD OS.

After install, plug back in both OS HD's. Set preferred as first to boot in BIOS setup. Boot the other using the one-time BIOS Boot Menu key given on BIOS splash screen.

This keeps the HD's independent to come and go as you please.

So how do I fix this mess ? :/

The OSes are on different harddrives, but I can only boot into Ubuntu (yet, still I have the Windows bootloader which dosent work (when selecting Windows 7 - Ubuntu isn't even listed - it starts Ubuntu).

If I run "bootsect /nt60 C:" in the guide you linked to I get "This tool can only be run on systems booted using PC/AT BIOS. This system was booted using EFI or some other firmware type."

You have to do it on the drive with your "boot" partition. For me, the drive letter was G:. So I had to do. CD G: Then CD boot. Then enter the command. bootsect /nt60 SYS. Try changing to C, D, E, or whatever. Maybe just type DIR to see if you can find the "boot" directory.

You can also try this;

MbrFix - Free software downloads and software reviews - CNET Download.com

I also fixed the problem on one machine which would try to boot but not start at all, it just started the grub loader and stopped, ( because there was no longer a Linux partition on it).

I took out all the drives except one and tried to boot from each one. When I got the error ( on the third try), I formatted that drive on an XP machine, and then replaced it. Everything worked after that.

Just ideas which may or may not work with your specific problem.
