I just installed ubuntu and I really like it, even though the dual-boot configuration took me at least 2 days :p

My dual-boot works fine, except for the fact my windows doesn't boot if one of my external drives is already connected?

Here is my setup: I have an SSD for booting that i split (100gb for windows, 25gb for ubuntu), and I dual-drive with an HDD that I use for storage. I have an uefi-bios and 64x I7 cpu, 16gb ram.

I have 2 external HDD's (for video and back-ups) that I allmost never disconnect.

If I come out GRUB, I can get into ubuntu without any trouble of my ext-HDD. But when I select my win7 and 1 of my HDD's is connected with 1 of my usb-ports, I get a black screen with a text-cursor. I can't type or do anything, only hard reset.

I re-installed my usb-ports, searched for hidden boot.ini in my HDD's, checked my boot-order in BIOS, but nothing works. So the only option is something with GRUB i think? Is there a way to make changes to my usb-boot? Or does anyone now what is holding my windows from booting?

Keep in mind that there is absolutely no problem booting windows if ext-HDD is not connected?

Hope you guys can help me, because I know nothing about ubuntu and GRUB :D

So, if an external HDD is connected and you boot into Ubuntu is ok. But if an external HDD is connected and you select Windows 7 in the GRUB, it doesn't work. Is that right? –  Lucio Mar 22 '13 at 21:45
    
I believe if you re-install grub with your HD's plugged in it will fix your issue. –  Weylin Schreck Mar 22 '13 at 22:41

Try booting into ubuntu and then type sudo update-grub . reset your bios to default from bios setup. Make sure, in your boot order internal HDD/SSD is selected as primary boot option.
